Performance

The 6.2L LS3 small-block V-8 is the standard engine in coupe and convertible models. It 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 brings a power rating increase to 436 horses (325 kW) and 428 lb.-ft. (580 Nm). A standard six-speed manual transmission and an optional six-speed automatic with paddle-shift control are offered.

Corvette coupe and convertible have a hydroformed steel rail backbone structure, which features cored composite floors, an enclosed center tunnel, rear-mounted transmission and aluminum cockpit structure. Suspension cradles, control arms, knuckles, springs, dampers, bushings, stabilizer bars and §teering gear deliver low mass, direct response and great driver feedback.

Three suspension choices allow drivers to choose the setup that best suits their driving style. The standard suspension is tuned for a balance of ride comfort and precise handling. The optional Magnetic Selective Ride Control suspension features magneto-rheological dampers able to detect road surfaces and adjust the damping rates to those surfaces almost instantly for optimal ride control. It includes larger, cross-drilled brake rotors.

Structure

The Z06 has a unique aluminum body structure for optimum stiffness and light weight for the fixed-roof body style. Perimeter rails are one-piece hydroformed aluminum members featuring cast suspension nodes, which replace many welded steel components on other Corvette models. Advanced structural composites featuring carbon-fiber are bonded to the aluminum structure. The wider front wheelhouses, for example, are carbon composites and the passenger compartment floors combine carbon-fiber skins with an ultra-lightweight balsa wood core.

The Z06 has a magnesium cradle that serves as the attachment point for the engine and some front suspension components. Magnesium is lighter than aluminum, yet incredibly strong. The magnesium cradle helps improve the front-to-rear weight distribution, as do carbon-fiber front fenders and wheelhouses. Engineers also moved the battery from underhood to a position in the rear cargo area, behind one of the rear wheels.

Interior

Corvette’s interior is inspired by the car’s dual-cockpit heritage. High-quality materials, craftsmanship and functionality help deliver premium quality meant to enhance performance driving. The instrument panel and doors are covered with cast-skin foam-in-place trim with the look of a leather panel. It is warm and inviting and has double the life of conventional trim materials. An AM/FM/XM radio with CD player and audio input jack is standard. An optional Bose audio system or an in-dash six-disc changer is available. Steering-wheel mounted audio controls are on all models. XM Satellite Radio with a one-year subscription is included with the Bose audio system.

A full-function OnStar system with Turn-by-Turn Navigation capability is standard and an onboard navigation system with voice recognition is available. It is a DVD-based system that uses a 6.5-inch (165 mm) color touch-screen display. Corvette also features k eyless access. When the owner touches the door’s touch pad, the key fob’s signal unlocks the door. The system’s emergency key and other remote-function controls are integrated in a single unit.

Design

The aerodynamics of the Z06′s exterior were shaped by the experiences of the Corvette racing program, where high-speed stability and cornering capability are paramount. While the race cars use large rear wings, the Z06′s elevated spoiler provides sufficient downforce to balance the road-worthy front splitter without adversely affecting aerodynamic drag.

For all of its race-inspired functionality, the Z06 is designed to be a daily-drivable high-performance vehicle. To that end, comfort and convenience are held to a very high standard. High-Intensity Discharge lighting, fog lamps, leather seating, dual-zone air conditioning, cabin air filtration and head-up display (HÚD) with track mode and g-meter are standard.

The Z06 gauge cluster displays the Z06 logo on the 7000-redline tachometer, and has a readout on the oil pressure gauge to reflect the higher standard pressure of the dry-sump oiling system. The seats feature two-tone leather surfaces with Z06-logo embroidery and contrasting stitching.

Engine

The Z06′s LS7 7.0L (427 cubic inches) engine delivers 505 horsepower (377 kW) in a 3,175-pound (1,440 kg) package – a combination that delivers 0-60 performance of 3.7 seconds in first gear, quarter-mile times of 11.7 seconds at 125 mph and a top speed of 198 mph (as recorded on Germany’s Autobahn).

Drivetrain

The Corvette Z06′s powertrain and drivetrain systems are matched to the LS7′s performance capability. The light, four-into-one headers discharge into close-coupled catalytic converters and through two-mode mufflers. The mufflers each feature a vacuum-actuated outlet valve, which controls exhaust noise during low-load operation but opens for maximum power.

At the rear of the LS7 engine, a single-mass flywheel and lightweight, high-capacity clutch channel torque to the rear transaxle. The six-speed manual transmission has been strengthened to handle the LS7′s increased torque load. The transmission includes a pump that sends transmission fluid to the front radiator for cooling. Úpon its return, the fluid removes additional heat from the differential lube before returning to the transmission. The six-speed transmission connects to a limited-slip differential, with enlarged ring and pinion gears. Stronger axle half-shafts with tougher universal joints transmit power to the rear wheels.

Suspension And Brakes

The Z06 retains the 105.7-inch (2,686-mm) wheelbase of other Corvette models, as well as the short-long arm suspension and transverse spring design, but it rides on all-new wheels, tires and brakes, as well as its own rear spring and roll stabilizer.

The firmer suspension works harmoniously with large 18 x 9.5-inch cast-spun aluminum wheels and 275/35ZR18 tires in the front, and 19 x 12-inch cast-spun aluminum wheels with 325/30ZR19 tires in the rear. The tires use the latest extended-mobility technology from Goodyear to provide a satisfactory ride, but still allow the vehicle to achieve lateral acceleration of more than 1 g.

Complementing the suspension system and large rolling stock is an equally capable four-wheel disc brake system, consisting of 14-inch (355 mm) vented and cross-drilled front rotors and 13.4-inch (340 mm) vented and cross-drilled rear rotors.

The front rotors are acted upon by large, red-painted six-piston calipers that use six individual brake pads. Individual brake pads are used because they deliver more equalized wear compared to what would otherwise be a pair of very long single-piece pads. The rear brakes use four-piston calipers with four individual brake pads. A four-channel ABS system is standard, as is a very competent active handling system – complete with a Competitive Driving mode.

The 2011 Chevrolet Corvette Z06 gets some new performance options and a limited-edition trim. Other versions of General Motors’ flagship sports car are largely unchanged. Corvette is offered as a hatchback or convertible in Base and sporty Grand Sport trims. These versions have a 430-horsepower 6.2-liter V8 engine. An optional “dual-mode” exhaust system increases horsepower to 436. Transmission choices include a 6-speed manual or 6-speed automatic.

Chevy offers other high-performance Corvette models, the Z06 and ZR1, both available only as coupes. Z06 has a 505-horsepower 7.0-liter V8, 6-speed manual transmission, specific suspension tuning, tires, and brakes. ZR1 has a supercharged 638-horsepower 6.2-liter V8 engine and 6-speed manual transmission. ZR1 differs from other Corvettes by its unique suspension tuning that employs GM’s Magnetic Ride Control adaptive suspension. It also uses lightweight carbon fiber on the hood, roof panel, roof bow, front-fascia splitter, and rocker moldings. Magnetic Ride Control and the ZR1′s carbon-fiber panels are new options on all 2011 Corvette models.

The Z06 can also be equipped as the Carbon, which GM says will be limited to 500 units. In addition to Magnetic Ride Control and carbon-fiber trim, Z06 Carbon has unique exterior and interior trim. All manual-transmission Corvette models incorporate GM’s Launch Control, which modulates engine speed in order to maximize grip during full-throttle launches. The ZR1 adds a “Performance Traction Management” system, which automatically adjusts the traction control and suspension to suit high-performance driving. Available safety features include ABS, traction control, antiskid system, and side airbags. Among the available features are a head-up display, navigation system, and wireless cell phone link. This report is based on evaluations of the 2010 Chevrolet Corvette.

Performance

The 6.2L LS3 small-block V-8 is the engine in Corvette and Grand Sport models. It is rated at 430 horsepower (321 kW)* and 424 lb.-ft. of torque (575 Nm)* with the standard exhaust system. An optional dual-mode exhaust system brings a power rating increase to 436 horses (325 kW) and 428 lb.-ft. (580 Nm). A standard six-speed manual transmission and an optional six-speed automatic paddle-shift automatic are offered.

Launch control is standard on manual-transmission-equipped models, and optimizes performance for full-throttle starts on a track. In competitive mode, the system will hold a predetermined engine speed while the driver pushes the throttle to the floor. That allows the driver to quickly release the clutch and the system modulates engine torque 100 times per second to maximize the available traction. The system is capable of approaching a skilled driver’s best effort and repeats it consistently.

Corvette and Grand Sport models have a hydroformed steel rail backbone structure, which features cored composite floors, an enclosed center tunnel, rear-mounted transmission and aluminum cockpit structure. Suspension cradles, control arms, knuckles, springs, dampers, bushings, stabilizer bars and steering gear deliver low mass, direct response and great driver feedback.

Coupe and convertible models offer two suspension choices that allow drivers to choose the setup that best suits their driving style.
