From Chevrolet press: Chevrolet brings significant updates to the Corvette Z06 for 2011, with special packages and new options that enhance performance and styling. They include: new standard Goodyear F1 Supercar Gen 2 tires and exhaust system tuning; new Z07 Performance Package; new CFZ Carbon Fiber Package; and the Z06 Carbon limited-edition model. The Z07 Performance Package brings greater handling and braking capability to the Z06, with Brembo ceramic brakes, with gray metallic calipers, similar to those offered on the Corvette ZR1; Magnetic Ride Control; Michelin Pilot Sport 2 tires; and 20-spoke wheels in competition gray (19 x 10-inch front, 20 x 12-inch rear).
The CFZ Carbon Fiber Package gives the Z06 lightweight aero enhancements similar to those found on the ZR1. Included in the optional package is a black-painted carbon fiber front splitter, rockers, roof panel and a body-color full-width rear spoiler. The Z06 Carbon limited-edition model blends the performance features of the Z07 package and the styling cues of the Carbon Fiber package. In addition to the features included with both new packages, this sinister-looking Z06 also includes a raised carbon fiber hood, along with black wheels, outside mirrors and headlamp housings.
Corvette Z06 is propelled by the LS7 7.0L (427 cubic inches) engine that delivers 505 horsepower (377 kW). Unique features include a racing-style dry-sump oiling system that helps ensure adequate oil pressure during high-load cornering. The LS7 engine powers a 3,175-pound (1,440 kg) package to help deliver 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. A six-speed manual is the only transmission offered with the engine.
