By winning every race in the 2004 season, the Corvette C5-R racing team wrapped up the most successful era in Corvette’s 50-year racing history. In its five years, the C5-R racing program took 35 victories in 55 races, four American Le Mans Series championships and three double victories at the 24 Hours of Le Mans.The Corvette Z06 sparked the second half of the C5’s life span with a Corvette model for the extreme performance enthusiast. Now, Team Corvette combines the numerous attributes of the sixth-generation Corvette with the technology and winning determination from the C5-R program to take the new Corvette Z06 to the next level in total performance.
Chevrolet introduced the Corvette Z06 at the North American International Auto Show. It is the fastest, most powerful car ever offered by Chevrolet and General Motors. It is comprised of an unprecedented level of capability and technology, making it one of the greatest performance values on the market. And with an unmistakably muscular appearance, the 2007 Z06 has a visual attitude that always looks ready to demonstrate Corvette’s winning attitude to any challenger around the globe.
New For 2007
* The safety and security of OnStar is now available on the Z06 when the 2LZ package is ordered.
* Because air bag technology advancements allowed engineers to remove the old passenger-side air bag on/off switch box, Corvette designers were able to provide a roomier glove compartment.
* New exterior color: Atomic Orange Tintcoat Metallicreplaces Daytona Sunset Orange Metallic. The specific tintcoat adds depth to create an exciting new color.
LS7 Engine
The all-new LS7 of the 2007 Z06 reintroduces the 427-cubic-inch engine to the Corvette lineup. Unlike the previous 427 engine, which was a big-block design, the new 7.0-liter LS7 is a small-block V-8 – the largest-displacement small-block ever produced by GM and a tribute to its 50 years as a performance icon.
With 500 horsepower and 475 lb-ft of torque, it also is the most powerful passenger car engine ever produced by Chevrolet and GM. The LS7 is easily identified under the hood by red engine covers with black lettering.
The LS7 shares the same basic Gen IV V-8 architecture as the Corvette’s 6.0-liter LS2, but the LS7 uses a different cylinder block casting with pressed-in steel cylinder liners to accommodate the engine’s wide, 104.8-mm-wide cylinder bores; the LS2 has 101.6-mm bores. And when compared to the LS2, the LS7 also has a different front cover, oil pan, exhaust manifolds and cylinder heads.
Internally, the LS7’s reciprocating components make use of racing-derived lightweight technology, including titanium connecting rods and intake valves, to help boost horsepower and rpm capability. The rpm fuel shut-off limit is 7000 rpm.
One of the clearest examples of the LS7’s race-bred technology is its use of titanium connecting rods. They weigh just 480 grams apiece, almost 30 percent less than the rods in the LS2 V-8. Besides being lightweight, which enhances high-rpm performance and rpm range, titanium makes the rods extremely durable.
Drivetrain
The Corvette Z06’s powertrain and drivetrain systems are matched to the LS7’s performance capability. The light, four-into-one headers discharge in to new, close-coupled catalytic converters and through to new “bi-modal” 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 which sends transmission fluid to the front radiator for cooling. Upon its return, the fluid removes additional heat from the differential lube before returning to the transmission.
Distinct 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. And while the racecars use large rear wings, the Z06’s elevated spoiler provides sufficient downforce to balance the road-worthy front splitter without adversely affecting aerodynamic drag. The Z06’s Cd is 0.31.
Uncompromising Amenities
For all 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. HID lighting, fog lamps, leather seating, dual-zone air conditioning, cabin air filtration and Head-Up Display (HUD) with track mode and g-meter are standard.
The Z06 also has a revised gauge cluster that displays the Z06 logo on the 7000-redline tachometer and has a new readout on the oil pressure gauge to reflect the higher standard pressure of the dry-sump oiling system. And, like other 2007 Corvettes, the Z06 has a new, smaller-diameter three-spoke steering wheel that provides a more agile, performance-oriented feel. The seats feature two-tone leathering surfaces, with Z06-logo embroidery and contrasting stitching.
Z06 options include a Bose audio system with an in-dash six-CD changer, polished wheels, a telescoping steering wheel, heated seats, side air bags, a navigation system with GPS, Homelink and XM Satellite Radio.
