Automobile Show

The all-new 2010 Lexus IS 350C and IS 250C hard-top convertibles give Lexus a coupe and convertible in the entry luxury segment for the first time. The IS C models combine the expressiveness of a convertible with the athletic styling of a coupe.


Sophisticated Retractable Hardtop Convertible

The Lexus IS250C and IS350C represent Lexus' second convertible and its first since the debut of the Lexus SC430 in 2001. Featuring a convenient single-switch operation, the new three-piece hard top provides open-air freedom with the top down without sacrificing the quiet and comfort of a coupe. Constructed primarily of lightweight aluminum, the hard top also provides surprising storage space but with low noise and increased security not typically found in soft-top convertibles. In addition, the top completely retracts with no elements remaining in view.

The Four-link roof assembly, also made of aluminum for a lightweight design, provides smooth even movement. Engineered to operate in an easy, efficient manner, each component is motor driven with detection switches, allowing the control unit to know their exact position at all times. In addition to the two main roof panels being constructed of light-weight aluminum, the back window's reinforced glass construction also lends itself to reduced weight. Weather-strip changes in areas around the doors and windows ensure tight seals.

A roof-speed brake-control system decreases the roof speed especially as it approaches the end of the closing operation in either direction, ensuring an elegant and quiet movement. On models equipped with available Intuitive Park Assist (IPA), sonar sensors in the rear bumper will stop the movement of the luggage door at the start of operation if it detects an obstacle will interfere. Also, a visual warning will appear on the instrument panel if a detected obstacle may soon interfere with top operation.

When the Lexus IS convertible's top is opened or closed, the power windows will automatically lower if in the closed position, and raise back up when the operating switch is held. Also, when the top is up, the door windows automatically lower 15 mm when the door opens, and then raise back into a fully closed position when the door closes. This ensures the doors' clean open/close function while also maintaining a tight seal around the glass. The aluminum hard top features an automatic front lock assembly that provides the interior security not found in soft-top convertibles. When the top is stowed in the down position in the rear of the Lexus IS convertible, the lock assembly is engaged to kept the panel in a fixed, stable position.

Convertible Aerodynamics

The Lexus IS convertible has a best-in-class 0.29 drag coefficient (Cd). This is accomplished with the help of underbody covers below the engine (with aerodynamic steps), the full floor, and fuel-tank covers, as well as s rear-floor diffuser with vertical fin and airfoil. Other areas that contribute to the low Cd include the design shape of the outer mirrors, high-mount stop lamps, and the rear tailamps. Fender fairings before the front and rear tires reduce airflow into the wheel house, improving aero characteristics and reducing air turbulence.

The Lexus IS convertible's air conditioning system automatically adjusts for the outside temperature when the top is lowered, improving interior temperature consistency and comfort. The system adjusts the air outlets, temperature and air flow exiting the outlets. The airflow volume adjusts to outside temperature and vehicle speed, while the temperature control adjusts to outside temperature, amount of sunlight and vehicle speed. The system also includes a pollen filter and variable-control compressor.

Convertible Body Rigidity

The Lexus IS convertible's body structure has excellent rigidity and strength, achieved by effective structural changes and additions to the existing IS sedan platform. Additional bracing was implemented to help provide excellent handling control, ride comfort and body durability while also minimizing weight gain.

Areas that received modifications or additions include the rocker area; A and B pillar under structure; side collision crossmember, and upper and rear-floor crossmembers. In addition, underfloor braces were added both in the front and the rear.

The transformation to a convertible also required reevaluation of noise, vibration and harshness (NVH) characteristics in order to meet Lexus standards. All body and chassis revisions have gone through extensive testing to ensure that the IS250C and IS350C have nearly identical NVH characteristics as the IS sedans. High-rigidity damping materials and asphalt sheets have been added to minimize vibration effects. Redesigned rear-suspension-mount bushings help reduce noise and vibration associated with the changes in body characteristics from a sedan to a convertible. Additional sound absorption and insulation materials have been optimally positioned to create a quiet, comfortable cabin.

Dual-Mode Redesign

The IS250C and IS350C's new exterior design has its lineage in the IS sedan but possesses its own dynamic styling, including unique characteristics when interchanging between convertible and coupe configurations. With the exception of the hood, all other body panels have been redesigned to blend seamlessly with the new three-panel folding roof.

The convex shoulder lines distinguish the convertible's profile, while the top-up configuration provides a sweeping cabin silhouette. With the top down, the belt-line draws up around the rear deck lid, providing a muscular look.

In the front, hood lines flow into a unique chrome grille shape, then continue down into an air inlet before flowing outward past the more distinctive elliptical fog-lamp design.

The rear view features a clean, continuous design, with flowing bumper corners and a strong bumper shape that flows inward towards the exhaust. All-new combination tail-lamp clusters feature LED lights and two distinct horizontal lines that emphasize breadth, while the LED brake light integrated within the standard rear spoiler imparts a sporty impression.

The Lexus IS convertible features two new wheels unique from the IS sedan line up. Standard 17-inch wheels utilize two multi-layered five-spoke patterns for a contemporary 10-spoke design with a clean liquid-graphite finish. Optional 18-inch wheels have an athletic five-spoke design with asymmetrical changes in shape and a liquid-graphite finish. Both feature the tire-pressure warning system found on the sedan models. In addition to standard all-season tires, an optional run-flat tire is available either with or without a spare, adding to the available luggage space.

Five colors common with the IS sedan are available on the convertible, ultrasonic blue is shared with the ISF, and Cerulean Blue is an all-new color exclusive to the IS C. Like the sedans, additional wet sanding is applied in mid-coat application to provide a premium finish.

Unique Interior Look

The Lexus IS convertible interior maintains the luxury touch points associated with the Lexus IS sport sedans, while new comfort and entertainment features provide a consistent atmosphere regardless of top configuration. Special attention was given to providing an attractive interior design when viewing the convertible externally. The door and side trim is fashioned to create continuity and continuous flow from front to back.

A four-seat configuration provides each passenger with their own comfort space, and the rear-seat console enhances the rear-passenger amenities with cup holders and storage. Soft padding on the sides of the console and the outer trim areas improve comfort. The rear headrests are retractable for improved visibility and the lever can easily be accessed from the rear console or from the driver's seat. Rear-seat comfort is enhanced by shifting seat position inboard, providing for sizeable headroom.

Eight-way adjustable power front seats, including power lumbar support are standard, and the available heated/ventilated function has increased heating range to include the shoulder areas and increases airflow in ventilation function. Front-seat backs are scaled inward, and slim, leather seat-back pockets help to maximize rear-seat legroom.

The gauge cluster is similar to that of the IS sedan, some additions on the Lexus IS convertible add style and function. A higher-contrast multi-information LCD, dial-color change for more contrast, and decreased surface-glass transmittance all enhance visibility when the top is down. The multi-information display also includes status of the hardtop while in transformation, providing a bar graph showing its progress. It also displays a warning to inform the driver if the roof is not completely open/closed, a rear obstacle may impede proper open/close operation, or if the open/close function is not available while the vehicle is in motion. Metallic trim around the two main gauges contribute to a premium look.

The interior adopts recycled materials in 13 various areas including door and side trim. The Lexus IS convertible will have three interior trim color options, including two new color combinations. In addition to black leather interior, a new alabaster color is joined by a distinctive alabaster/blue contrast trim.

Dynamic Driving Performance

The IS250C and IS350C provide a consistent blend of driving performance and comfort in either convertible or coupe configuration. They share common double-wishbone front and multi-link rear suspension systems with the IS sport sedan models.

The double-wishbone front suspension received a number of changes to provide the handling stability and ride comfort required for a convertible. The torsional rigidity of the suspension bushings was optimized, as was the spring constant on the coil springs, and the shock absorber damping force. The stabilizer shape and the Electric Power Steering (EPS) gear ratio were also revised to help provide improved control.

The multi-link rear suspension also received similar changes to suspension bushings, coil springs and shock-damping force. In addition, the rear-suspension tower was lowered with enhanced rigidity to help provide rear control and linear yaw response; it also provides improved trunk space.

Performance Oriented Drivetrains

The Lexus IS convertible models feature the same powertrains as the IS sedans. The IS 350C's 3.5-liter V6 delivers exhilarating performance with outstanding 306 horsepower at 6,400 RPM along with 277 lb.-ft. of torque at 4,800 rpm. The IS 250C's 2.5-liter V6 engine has a great combination of fuel efficiency and performance. The IS 250C's V6 produces 204 horsepower at 6,400 RPM and 185 lb.-ft. of peak torque at 4,800 rpm. Both engines utilize aluminum cylinder blocks and heads, while employing dual Variable Valve Timing with intelligence (VVT-i), which controls timing on both the intake and exhaust camshafts.

A direct-type fuel-injection system provides a cooling effect in the cylinders, enabling the high compression needed to extract maximum energy from the fuel. Aside from its larger displacement, the 3.5-liter V6 differs chiefly in that it augments the direct fuel injection with port fuel injectors. In light- and medium-load conditions, these additional injectors help produce a precise burn, increasing power and efficiency, while reducing emissions. A dual exhaust system reduces backpressure at higher engine speeds. Like IS sedans, the IS250C and IS350C meet the Ultra-Low Emission Vehicle II (ULEV II) certification.

An advanced six-speed automatic transmission with steering-wheel-mounted paddle shifters is standard on the IS 350. The IS 250 comes with either a six-speed manual transmission or the paddle-shift, six-speed automatic transmission.

Easy Access Utility & Comfort

The new Lexus IS convertible emphasizes easy access and rear-seat comfort. In addition to front doors that are 11.8 inches longer than the IS sedans, two convenient fold-forward lock-release levers are standard on both sides of the front passenger seats, making it easier to operate from any location inside the vehicle. In addition, the passenger seat features a power slide button on the top of the seatback to ease rear seat ingress/egress. An available new automatic one-touch, easy-entry power-seat mechanism provides even easier egress and ingress through quick-acting, front-seat fold-and-slide activation. The two passenger doors also have three open-stopping positions (rather than the normal two) to add convenience in various parking situations with different spacing between vehicles. The IS C also is equipped with a standard power tilt and telescoping steering column to help the driver quickly get into a comfortable position.

The optional Intuitive Park Assist (IPA) system uses ultrasonic sensors to detect objects close to the car's front and rear bumpers, alerting the driver and showing distance to objects in the multi-information display within the speedometer. When any IS model is also equipped with the optional navigation system, information on objects detected in the rear are shown in greater detail on that system's seven-inch display via the backup camera.

The optional Pre-Collision System (PCS) is packaged with Dynamic Radar Cruise Control, which uses millimeter-wave radar to measure and help maintain a set distance from a vehicle traveling ahead. PCS relies on the radar sensor to detect obstacles in front of the car, and a PCS computer with sensor inputs from vehicle speed, steering angle and yaw rate is designed to determine whether a collision is unavoidable. In such a situation, PCS alerts the driver via sound and visual warnings while preemptively retracting front seat belts and pre-initializing Brake Assist so that increased braking will be applied the instant the driver depresses the pedal.

Standard Hill-start Assist Control helps prevent the vehicle from moving backward when the driver moves their foot from brake pedal to the accelerator. The system will also be available for the first time with the manual transmission.

The standard Lexus Premium Audio System features a six-disc, in-dash CD changer, and eight speakers. An equalizer system maintains the same acoustic field when the top is either open or closed, compensating for the natural loss of bass sounds when open. In addition to the 1/8th-inch audio mini jack on the IS sedan, the Lexus IS convertible will also have a standard USB connector in the center console for interface with an iPod® that will not only play the music on the device, it will display information on the navigation screen such as artist, album and song track.

Bluetooth® Audio wireless connectivity is another new feature available for those customers with compatible devices. Standard XM® satellite radio (subscription required) offers a wide variety of programming, while standard hands-free voice recognition and Bluetooth® technology for models without optional navigation allow phone calls to be made and received while driving.

Lexus' latest Hard-Disk Drive (HDD) navigation system, with a new set-up display and increased audio-display tabs, is available on the Lexus IS convertible and is complete with a seven-inch VGA touch-screen, back-up camera, and XM® NavTraffic and NavWeather (subscription required). The navigation system also includes as standard on all navigation-equipped Lexus IS convertibles Lexus' latest voice recognition system, Voice Command, which builds upon the previous-generation system's functionality, adding more spoken-command flexibility. With Voice Command users avoid having to speak commands in a specific order (e.g., "Phone > Dial by Name > Dial Bob"). Now this same task can be completed simply by saying, "Call Bob at home." The Voice Command system also works to control many functions of the audio system, heating and air conditioning, and the navigation system. Commands such as, "Make it cooler," "Let's find XM channel 46," "Show me Japanese restaurants," and "I need a gas station," make tasks easier to accomplish, in fewer steps, and help allow drivers to focus more on the road ahead. A Mark Levinson® Premium Surround Sound Audio system, exclusive to Lexus, is available in conjunction with the optional navigation system. This 12-speaker audio system features discrete 5.1 multi-channel playback with 5.1-channel speaker architecture. Its 10 amplifier channels provide 270 watts total output at 0.1 percent total harmonic distortion (THD). From 20-20,000hz, the Mark Levinson system plays conventional CDs and specially encoded DVD audio and DVD video discs, plus MP3/WMA-formatted CD-R/RW and DVD-R/RW. DVD movies can be viewed on the optional navigation system's seven-inch color touch screen when the parking brake is engaged.

Lexus Safety & Security

Standard Vehicle Dynamics Integrated Management System (VDIM) governs all of the vehicle's dynamic handling systems - the Anti-lock Braking System (ABS), Brake Assist, Vehicle Stability Control (VSC) and Traction Control (TRAC) - employing them collectively and seamlessly to make corrections while helping provide higher dynamic capability. VDIM also interfaces with the electronic throttle control system.

The Lexus IS convertible features large, ventilated four-wheel disc brakes with Anti-lock Braking System (ABS), Electronic Brake force Distribution (EBD) and Brake Assist. The IS350C is equipped with 13.15-inch front and 12.20-inch rear rotors with aluminum four-piston front calipers to aid in heat dissipation and stopping power and reduce unsprung weight. The IS250C has 11.65-inch front and 12.20-inch rear rotors.

Passive-safety technology begins with a number of body-structure changes integrated in the IS250C and IS350C to help augment strength and torsional rigidity. Seatbelt pre-tensioners and force limiters are used for the front seats, while the rear seats adopt emergency locking retractor seatbelts with an automatic locking retractor.

In addition to the dual-front airbags, the Lexus Supplemental Restraint System (SRS) for the Lexus IS convertible includes new enlarged front-seat-mounted head and torso side airbags, and knee airbags for both the driver and the front passenger. The front-passenger airbag features two chambers, creating an indentation in the center impact area that helps to provide overall occupant protection.

The available High Intensity Discharge (HID) headlamps paired with the Adaptive Front-lighting System (AFS) helps to illuminate a curve as the driver steers into it.

The standard SmartAccess keyless entry and push-button-start/stop allows the driver to keep the access key FOB in a pocket or purse. The standard HomeLink® programmable garage door opener also operates home security devices and other systems.

BMW has a long and illustrious history of building two seat sports cars. From the very first 3/15 PA Wartburg Roadster in 1930, BMW has produced highly distinctive roadsters. With their long bonnet, setback glasshouse, front engine rear-wheel-drive configuration and with the two seats positioned close to the rear axle, every BMW roadster lives up to the ultimate driving machine promise.


Now, nearly 80 years after the first BMW roadster went on sale, the latest has been launched in the UK. Featuring a host of innovations never before featured on a BMW of this type, the new BMW Z4 is the first to come with a two-piece, electro-hydraulically operated Retractable Hard-Top roof that can be raised or lowered in 20 seconds. The new BMW Z4 is also the first roadster to be offered with Adaptive M Sport Suspension. This system features a ride height 10mm lower than the standard car for a more dynamic drive. Adaptive M Sport Suspension also comes with electronically controlled dampers that offer three different configurations from Normal to Sport+ so a driver can fine tune the car's set-up.

The standard Drive Dynamic Control function is another BMW roadster first and allows the driver to alter the chassis configuration to suit their needs. Now the vehicle has the capability to morph between comfortable yet sporty cruiser through to outright performance car. Depending on model specification, the throttle and steering response, level of ride comfort, Dynamic Stability Control response and, on automatic or Double Clutch Transmission cars, gear change times can all be altered.

Drivetrain

To underscore the potency of the new BMW Z4 the model comes with a choice of three high output six-cylinder powerplants. The range flagship is an International Engine of the Year winner in the shape of the 3.0-litre twin-turbocharged engine. The 306hp BMW Z4 sDrive35i powers its way from zero to 62mph in 5.2 seconds before going on to an electronically-limited top speed of 155mph. The strong performance credentials are matched in terms of economy and emissions.

The BMW Z4 sDrive35i records a combined consumption figure of 30.1mpg and CO2 emissions of 219g/km. It is worth nothing that the sDrive35i can be specified with a Double Clutch Transmission and a vehicle so equipped records a faster zero to 62mph time of 5.1 seconds, 31.4mpg consumption and lower CO2 emissions at 210g/km.

Joining this model in the launch line-up are the BMW Z4 sDrive23i and the Z4 sDrive30i. Both use the same magnesium aluminium alloy engine with Double VANOS and VALVETRONIC technology, but with varying capacities. The 2.5-litre entry-level BMW Z4 sDrive23i produces 204hp to achieve its zero to 62mph time of 6.6 seconds and a top speed of 151mph. In contrast the BMW Z4 sDrive23i is capable of a combined 33.2mpg and CO2 emissions of 199g/km.

The BMW Z4 sDrive30i comes with a 3.0-litre powerplant producing 258hp. The six-cylinder engine records a zero to 62mph time of 5.8 seconds before going on to an electronically-limited top speed of 155mph. Like the BMW Z4 sDrive23i, the Z4 sDrive30i posts impressive combined consumption and CO2 emission figures, recording 33.2mpg and 199g/km.

Transmitting the power to the road in all three Z4s is a six-speed manual gearbox as standard. Customers of the BMW Z4 sDrive23i and the Z4 sDrive30i who prefer the characteristics of an automatic can specify a six-speed Sport Automatic transmission featuring gear change paddles on the steering wheel. Buyers of the BMW Z4 sDrive35i can choose a seven-speed Double Clutch Transmission, again with gear shift paddles located on the steering wheel.

Increased comfort and practicality

BMW's latest roadster is larger than its predecessor measuring 148mm longer at 4,239mm and 9mm wider at 1,790mm, and this results in greater interior space and luggage capacity. With the roof up, headroom has been increased by 44mm while the greater car width and design enhancements have led to 20mm more shoulder room and 43mm more elbow room.

Driver visibility in the BMW Z4 has also been improved. All round visibility is up by 14 per cent while, courtesy of the four electric windows creating a larger glasshouse, side visibility is up 40 per cent. The Retractable Hard-Top roof features a glass rear window and this too improves visibility by 52 per cent.

The most recent incarnation of iDrive makes its first appearance on a BMW Z4. The optional BMW Professional Multimedia Navigation system features a hard disc drive capable of 12Gb of audio file storage and BMW ConnectedDrive functionality. A vehicle specified with this system also comes with eight programmable Favourite buttons as system shortcuts.

Market

The new BMW Z4 has been introduced to compete head-on with the two big biggest sellers in the UK premium roadster market - the Mercedes SLK and the Audi TT Roadster. According to BMW's own market research one of the key reasons for selecting the Mercedes over the previous BMW Z4 was the added benefit of a folding metal roof. The majority of buyers in this segment also craved a degree more comfort and practicality. The designers and engineers of the new BMW Z4 took these considerations on board so the BMW Z4 should now appeal to a broader church, while at the same time not diluting the range's previous excellent driving dynamics.

Drawing inspiration from classic sports cars, the 2009 Pontiac Solstice coupe was created for drivers who appreciate both dramatic styling and balanced performance. Unveiled at the New York Auto Show as a GXP model, the Solstice coupe builds on the success of the convertible model while offering a greater range of all-season driving opportunities.

For drivers still wanting an open-air experience, the coupe also features a removable roof panel, fully opening the cockpit to all of the sensations of the road.

"Today's Solstice is the top-selling roadster in the U.S., and we believe this new model has even broader appeal," said Jim Bunnell, Buick-Pontiac-GMC general manager. "The coupe has all the design cues and pleasing performance of the original roadster, and is an all-season alternative for people who enjoy open-air driving."

The coupe is expected to arrive in Pontiac dealerships in early 2009

The making of a coupe

The new coupe was inspired by the Pontiac Solstice coupe concept shown at the North American International Auto Show in 2002. True to the concept, it is a modern sports car with classic lines. The roofline has a "fastback" shape with stylized "rails" that run from the front of the roof to the rear, culminating in a stylish and functional ducktail-style rear spoiler.

The coupe's roof is fixed aft of the B-pillars, with side windows and a rear liftglass for access to the cargo area. The roof panel is easily removed from the passenger compartment, and an optional soft roof cover stores in the cargo area. A home storage case for the roof panel will be offered through GM Accessories.

Engineering the design

Despite its dramatic new look, engineers made only minor structural changes to create the Pontiac Solstice coupe. The rear fenders and rear fascia are the same as those on the convertible. New taillight assemblies flow more smoothly into the tapered roofline.

"The Solstice coupe represents a major collaboration of design and engineering," said Bruce Kosbab, chief engineer. "The sleek lines of the new roof give the car a fresh appearance, yet only minimal changes were made to the body structure - it's a great example of building on an already solid foundation."

Lightweight structure

The roof's structure was strengthened with additional support elements, including an aluminum roof bow attached with aluminum brackets. The bow and brackets are stiff, yet low in mass, a design feature that pervades the coupe's overall construction. The roof includes a lightweight sheet molding compound cover affixed to a rigid aluminum frame for additional lightweight support. A lightweight magnesium roof panel frame weighs just 31 pounds (14.2 kg) and can be removed by one person. The cover is also made of sheet molding compound

Powertrain and suspension

Because the change to a coupe body style resulted in only a slight increase in curb weight, no drivetrain or suspension changes were necessary to shift from the convertible body structure. Initial tests have shown that the Solstice coupe will deliver ride and handling, acceleration, braking and fuel economy comparable to the convertible model.

The coupe is powered by a standard 2.4L Ecotec four-cylinder engine that generates 173 horsepower (129 kW), while the GXP version is equipped with a 2.0L turbocharged Ecotec engine with 260 horsepower (194 kW).

Interior additions

Much of the coupe's interior remains the same as that of the convertible. However, the area behind the seats was redesigned for easy access to the cargo area, and a storage tray was mounted directly behind the headrests.

Removing the folding-top mechanism made way for a new, flat cargo floor and several storage compartments. The cargo area's covered bins provide secure storage for smaller items. Cargo tie-down hooks help secure irregularly shaped items.

The Chevrolet Corvette Grand Sport combines the Corvette's LS3-based powertrain with unique, wide-body styling and a racing-bred suspension for a distinctive model that delivers a great balance of road and race track performance. It is offered in both coupe and convertible body styles, with either a six-speed manual or six-speed automatic transmission. The LS3 6.2L engine is rated at 430 horsepower (321 kW) and 424 lb.-ft. of torque (575 Nm) with the standard exhaust system. An optional two-mode exhaust system elevates the power ratings to 436 horses (325 kW) and 428 lb.-ft. (580 Nm). The Chevrolet Corvette Grand Sport replaces the Corvette's previous Z51 package and brings a greater degree of handling performance, with wider wheels and tires; revised shock, stabilizer bar and spring specifications; and specific gearing. The equipment enables cornering capability of 1.0 g, as well as a 0.2-second improvement in 0-60 acceleration vs. standard LS3-powered models.

Chevrolet Corvette Grand Sport coupe models equipped with the manual transmission are uniquely outfitted for race track competition, too, with a dry-sump oiling system, differential cooler and a rear-mounted battery.

The complete list of content and special features for the Chevrolet Corvette Grand Sport includes:

* Wider front and rear fenders - including specific front fenders with integrated Grand Sport badges
* Z06-style front splitter and tall rear spoiler
* Functional brake ducts and extra cooling
* Unique 18-inch front and 19-inch rear wheels; painted finish standard and chrome finish optional
* Large 275/35ZR18 tires in front and 325/30ZR19 tires in the rear
* Z06-size brakes, including 14-inch (355 mm) front rotors with six-piston calipers and 13.4-inch (340 mm) rear rotors with four-piston calipers
* Specific manual transmission gear ratios
* Specific rear axle ratio on automatic-equipped models
* With its special equipment, the Chevrolet Corvette Grand Sport offers a unique blend of performance and amenities. Its suspension package approaches that of the Chevrolet Corvette Z06, but includes a removable roof on coupes (Z06 has a fixed roof) and, of course, the availability of a convertible body style. Also, the paddle-shift six-speed automatic transmission is offered, while a manual transmission is the only choice with the Z06.

All of Corvette's exterior colors are offered on the Chevrolet Corvette Grand Sport, and an available Heritage package adds iconic front fender hash marks offered in four colors, as well as two-tone seats with Grand Sport embroidery. The Chevrolet Corvette Grand Sport can be ordered with 1LT, 2LT, 3LT and 4LT trim packages, too.

Grand Sport history

Envisioned by legendary Corvette engineer Zora Arkus-Duntov as a factory-built, lightweight and race-ready production model that would trump domestic and foreign road-racing competitors, the original Chevrolet Corvette Grand Sport was a promising idea that led to the production of five special prototypes in 1963. The project was later shelved, following GM's agreement to stay out of manufacturer-backed motorsports.

The five prototypes were based on the styling of the 1963 Corvette and were hand-assembled under Duntov's watchful eye. But while they looked like production models, the prototypes were purpose-built race cars that shared little with their assembly-line cousins. Duntov also oversaw the Chevrolet Corvette Grand Sport engine program that featured a special, 377-cubic-inch small-block V-8 with side-draft carburetors.

Although never officially sanctioned by General Motors, the five Grand Sport prototypes saw extensive racing experience throughout the 1960s in the hands of "private" racers who had strong contacts within Duntov's engineering circle. All five original cars are accounted for today and are among the most valuable in the collector market.

Chevrolet offered a limited-edition  production model in 1996, commemorating the original racing cars and marking the end of the C4 era in Corvette production. All of the 1,000 examples were painted Admiral Blue and featured a white center stripe and red "hash mark" graphics on the left front fender, a graphic scheme that mimicked the look of some of the original race cars.

The definitive version of the gorgeous exclusive Alfa Romeo 8C Competizione, Gran Turismo car that is to be produced in a limited edition makes its debut in Paris. The car, designed by Alfa Romeo, is directly derived from the concept car that aroused such admiration at the 2003 Frankfurt Motor Show and has benefited from the best technical and industrial know-how that the Alfa-Maserati Sports Centre can offer. The cooperative venture between both manufacturers was conducted with a view to ensuring integration between the Alfa Romeo design departments and the Maserati production departments.


The Alfa Romeo 8C Competizione is inspired by Alfa Romeo's glorious past, projecting its brand values of technology and emotion into the future. The historical allusions begin with the evocative name, recalling the great sporting tradition of Alfa Romeo. The 8C code was used to identify cars (racing and on-road) of the Thirties and Forties equipped with the revolutionary eight cylinder engine produced by the famous designer Vittorio Jano. The term 'Competizione' is intended as a homage to the '6C 2500 Competizione', a sports coupé driven in 1950 by the duo Fangio and Zanardi in the famous Mille Miglia race.

The name, '8C Competizione' is not an arbitrary invention but a distinctive mark of Alfa Romeo's own sporting history. A veritable legend that has arisen out of the innumerable victories won on circuits throughout the world through the skill of men and their passion for racing, engine research and advanced technology and a reawakened taste for new challenges.

This link with the values of Alfa Romeo's history adds extra poignancy to the term 'Competizione'; when projected into the future it represents the sense of constant dynamism that distinguishes a brand engaged in a quest for excellence, increased competitiveness and technological innovation. This is the explanation behind the role of the new car, which is not a point of arrival but a point of departure designed to reaffirm Alfa Romeo's unique place in the world: its ability to match a thrilling shape to driving satisfaction.

Styling and aerodynamics: tradition and innovation

The attractive shape created by the Alfa Romeo Style Centre makes this car with its two bucket seats unique in the Gran Turismo scenario. The designers have worked hard to ensure that the aerodynamic and performance demands have not altered the car's original concept. The style maintains an incredibly clean shape, uncluttered by any element interfering with the overall harmony.

The solutions introduced on the Alfa Romeo 8C to achieve the highest levels of aerodynamic efficiency are not limited to the shape. Air wraps around the car and follows its natural course, unhindered by corners and unevenness. All the pillar and glass surfaces and profiles together with the door mirror shape and position have been optimised by mathematical modelling and also by wind tunnel tests and tests on actual models. Much attention has been devoted to the creation of a ground effect that has allowed a negative Cz (lift coefficient) to help increase stability at high speed, as on racing cars.


The compact dimensions concentrate the aggression of a car designed to ensure maximum driving efficiency.

The car surfaces are highly sculpted and skilfully moulded. In detail, the body is given extra dynamism by the horizontal furrow cut into the side above the front wheelarch. The big wheels and powerful musculature of the rear wings emphasise the model's personality and strength without detracting from the lines that flow smoothly, almost as though to underscore the formal good looks of the individual exterior details: the drop-shaped headlight embedded, gem-like, in the front wing, the led tail-lights that are a blend of technology and rationalism, the spare door handle. The front end still displays the distinctive Alfa Romeo traits, with a new interpretation of the 'whiskers' and shield.


The innovative shape heralds the details and proportions of future Alfa Romeo cars but is also redolent with past thrills and historical allusions: the 33 Coupé Stradale, the Giulia TZ and many other great names of motoring history. The Alfa Romeo style centre also developed new colours to emphasise the shape of the Alfa Romeo 8C Competizione that match the car's sinuous shape while also suggesting modernity and a hint of technology.

8 cylinder 4.7 engine: Italian 'belcanto'

The engine is the beating heart of any Alfa Romeo. In this case it takes the form of a brand new 90° V 8 cylinder unit with a cylinder capacity of 4691 cc that was designed with one aim in mind: to ensure extraordinary performance while still offering a smooth drive and being usable in all circumstances, from the track to city traffic.

The top engine performance figures may be summarised as a maximum power output of 450 bhp at 7000 rpm, a peak torque of 470 Nm at 4750 rpm and a top speed of 7500 rpm.

The layout of internal fluid movements and the cylinder head cooling system is designed to achieve high duct permeability and effective intake load cooling to maximise volumetric efficiency and engine performance.


Harmonisation of the intake and exhaust geometry together with the introduction of continuous variable valve timing on the intake camshafts and optimisation of the combustion chamber and engine calibration means that 80% of torque is available from 2000 rpm.

In sporty driving conditions over mixed routes, the power unit offers impressively short response times due to the high permeability of the intake duct and the low inertia of the flywheel-twin plate clutch system.

A crankshaft with counterweights at 90°, fully balanced through careful selection of connecting rods and pistons, ensures the engine runs with low vibration levels.

The engine block and base assembly is in aluminium with 5 main bearings to ensure the structure is very rigid with little loss due to friction. The cylinder heads are also in aluminium alloy.

All the ducts (water, oil, secondary air) are cast directly into the engine to produce a system with great rigidity, low dimensions and guarantees of safe installation, i.e. great reliability.


Casting accessory systems into the main engine casting and the use of very rigid, thick-walled components ensures that little noise radiates from the engine and the components are very reliable.

Longitudinal engine packaging has also received particular attention, as evidenced by the introduction of a single chain timing system that guarantees exceptional lifetime dependability.

Special attention has also been devoted to the acoustic definition and tuning of the intake and exhaust in the quest for a sound timbre that enhances the car's character and makes it unmistakable. The result is a full, distinctive sound, emphasised by the permeable intake system and an exhaust system with electronically controlled valves that enhance the car's sound without infringing any type-approval or environmental constraints.


Transmission, robotised gearbox and self-locking differential

The engineers used a layout familiar from other Alfa Romeo cars on the 8C Competizione: the transaxle architecture with gearbox at the rear that is an acknowledged asset of Alfa Romeo cars. This layout allows outstanding dynamic performance while also offering the active safety for which Alfa Romeo cars are fabled.

The engine-gearbox unit is designed in accordance with a transaxle configuration that ensures the weight distribution is very effective for vehicle handling. Due to the small axial engine size and the integration with frame components from the drawing board, the entire power unit can be housed well back to ensure the required sporty configuration.

The 6-speed gearbox with computerised speed selection by means of levers behind the steering wheel is designed to ensure ultra-slick gear shifts and may be used in Manual-Normal; Manual-Sport; Automatic-Normal; Automatic-Sport and Ice modes. The self-locking differential allows acceleration and stability to be managed with extraordinary efficiency in all situations.



Suspension, wheels and braking system

In the very best Alfa Romeo tradition, the engineering is directly derived from the race track. The suspension on the new model is no exception, with a double wishbone layout, forged aluminium axle carrier and arms and extra strut for toe-in control.

The braking system offers perforated, ventilated discs with aluminium brake callipers to ensure prompt, effective braking even with heavy use. To ensure the car stays glued to the road, it is fitted with 20" tyres specially developed to ensure outstanding performance: 245/35 at the front and 285/35 at the rear, fitted on perforated rims in fluid moulded aluminium to ensure lightness and maximum brake ventilation efficiency.

To ensure the car is entertaining and safe in any driving condition, the Alfa Romeo 8C Competizione comes with the latest Alfa Romeo VDC, an advanced stability and traction control system to ensure the driver feels at one with his car.



Rigid, light structure

A rigid, light structure is the rule when configuring a good high performance car. This is also the guiding principle behind the Alfa Romeo 8C Competizione. In detail, the compact frame is in steel to achieve the greatest torsional rigidity to ensure an accurate, safe drive at all times while the body is in carbon fibre. This choice was motivated by the need to minimise weights while also optimising the car's centre of gravity for better agility and handling on demanding routes.



Interiors: personality and technology

The car's distinctive look comes from extensive use of composite materials on the facia and interior panels. This is a technical choice but also reinforces the car's spirit and emphasises its personality. The same thinking lies behind the adoption of anatomical seats made out of carbon fibre that can be adjusted and customised on the basis of the driver's physical characteristics (a facility previously reserved for racing cars).



Everything is designed and produced to ensure the greatest user-friendliness for the driver and whoever is lucky enough to share the thrill: relaxed driving position, intuitive instruments that are always visible, robotised gear levers secured to the steering column and easy to reach without removing your hands from the sporty steering wheel.

The carefully-crafted and detailed finish naturally allows the car to be customised to the driver's taste and a choice of different interior environments is available.


The absolute satisfaction of a sporty drive

To see it is to love it: wide tyres, low-slung ride and styling of poised aggression. To die for, in fact. Hear the engine and weep: a full, convincing throaty roar. Now all that remains is to sit behind the wheel, engage first gear and you are off to try out your Alfa Romeo 8C Competizione. You are left with one doubt: how will you drive a sports model whose bonnet conceals a 4700 cc eight cylinder engine hat unleashes 450 bhp of power and 470 Nm of torque when you touch the accelerator. The unexpected answer is: with great ease - even more easily, simply and instinctively than your normal car in fact. Provided you allow yourself the time and satisfaction (because this is about pleasure, after all) of getting used to the more direct controls and prompter responses: the sort you could only expect from a true sports car on mixed routes or - even more so - on the track where speed and transverse acceleration are much more controllable.

The new Alfa Romeo 8C Competizione is self-avowedly an Alfa in its uncompromising sense of control and driving satisfaction. Driving comfort and dynamic behaviour have always been specific features of Alfa Romeo cars: on this car, they amount to a real strength.


Alfa Romeo 8C Competizione: a legendary name for a unique car

Since the very beginning, the Alfa Romeo spirit has been driven by a constant quest for technical perfection, achieving performances that are better and better. This is all about the engine: the beating heart of every Alfa Romeo car. Racetracks throughout the world have provided the perfect backdrops for truly unique technical and technological progress, with Alfa Romeo always occupying the highest position on the winners' podium.

The key to Alfa Romeo's engineering prominence was the 8 cylinder engine developed during the first half of the Twenties by a young engineer named Vittorio Jano. His original brief was to revise the 6 cylinder engine to meet the needs of standard production model buyers and also to stand up to the competition offered by rival manufacturers in races.

The first 8C was tested in 1923, with the P1, already fitted with a compressor and twin spark ignition, and then the P2. Its debut could not have gone better: in 1925 the Alfa Romeo P2 won first place in the first World Championship. The positive effects of these innovations were not restricted to the engines of production cars but the glory of this result was included in the 'Alfa Romeo - Milan' badge in the form of the laurel crown that was to adorn all Alfa Romeo cars from that day on.

At the beginning of the Thirties, the powerfully reliable 8 cylinder engines - now in light alloy - purred like cats under the bonnets of stylish cabriolets and coupes (whose bodies were built by the Milanese Zagato and Castagna) and roared like lions in the dust of races such as the Mille Miglia and Targa Florio, that added to the impressive list of victories. The thrilling wins achieved by the Alfa Romeo 8C in 1931, 1932, 1933 and 1934 at Le Mans deserve special attention (the car was later called the 'Le Mans' in the wake of these great successes).

The 8 cylinder engine achieved its technical peak in the Alfa Romeo Tipo B engine, known as the 'P3' to highlight its technological relationship with the P2. Campari, Nuvolari, Caracciola, Borzacchini, Marinoni, Guidotti and Fagioli were just some of the champions who owed their successes to the 1932 and 1934 versions of the 8C engine in the face of the challenges posed by the most prestigious circuits in the world.

The continual progress and consistent technical research culminated in the 8C 2900, the unbeaten star of racing from the Mille Miglia to the Le Mans 24 hour. The car, an extremely stylish 8C with its body built by Touring especially for Le Mans, was driven peerlessly by its driver Biondetti. This engine was exceptionally long-lived: an 8C 2900 B driven by Biondetti and Romano won the Mille Miglia again in 1947, proving yet again and over an exceptionally arduous route, that Alfa Romeo engines were possessed of truly extraordinary power and reliability.

World War II only halted the victorious progress of the 158 for a short period. The legendary 'Alfetta', a distillate of superlative automotive engineering qualities, first saw the light in 1946. In the words of Juan Manuel Fangio, driving this 8 cylinder car was like 'holding the bow of a Stradivarius in your hands'. First the 158 and later the 159 brought Alfa Romeo laurels in the first two modern Formula 1 world championships, with Nino Farina in 1950 and with Fangio in 1951.

After the Formula 1 victories, Alfa Romeo decided to withdraw from racing to devote itself to the demands put on it by its latest arrival, the 1900 and later the Giulietta range. 1967 saw the return of the powerful 8 cylinder engine fitted to racing 33 models and responsible for the attractive, resolute shape of the road version of the 33. This car also enjoyed a very encouraging racing debut, with Teodoro Zeccoli taking top position on the winners' podium after the uphill race in Fleron, Belgium, in a 33/2 Sport Prototype.

Other 33 cars met with considerable success on tracks and circuits throughout the world during the Seventies. This technical perfection was transferred to standard production cars such as the Montreal, a car of great prestige and performance, whose 8 Cylinder engine was derived from the unit fitted to the 33 models used for racing. In 1977, the 8 cylinder engine was fitted to a limited series of the Alfetta GTV, produced by Autodelta which thus continued the sporting tradition applied to engine production.

Now the legendary heart of that engine comes back to beat under the bonnet of the new Alfa Romeo 8C Competizione.
