Chevrolet Corvette

With the addition of the Grand Sport model last year, and the new Z06 Carbon Limited Edition for 2011, there are plenty of Corvettes to choose from. The base coupe and convertible have a 6.2-liter, 430-hp V8 engine, known as the LS3, and a standard 6-speed manual transmission. A 6-speed paddle-shift automatic is optional. The paddle shifter includes a "push and hold" function to make it easier to transition back to automatic after you've had your fun through the chicane.

The sport-tuned Z06 comes with the larger LS7 engine, which is a 7-liter powerplant that makes 505 hp and is connected to a 6-speed manual. This combination is capable of 0-60 mph in 3.7 seconds-in first gear. The body is lightened by using an aluminum structure with bonded carbon fiber composites. It features a firmer suspension, 6-piston brake calipers and 18-inch front/19-inch rear aluminum wheels. New this year is a Z06 Carbon Limited Edition, which adds the Z06 Ultimate Performance Package and Z06 Carbon-Fiber Package, which are also available separately. The ZR1 turns up the heat with the LS9 6.2-liter engine and Tremec 6-speed manual transmission, plus a Performance Traction Management system for improved on-track performance. It's built on the same chassis as the Z06, but with a specially tuned suspension and Michelin performance tires exclusive to the ZR1.

With 638 horsepower and 604 pound-feet of torque on tap, the ZR1's top speed has been tested at over 200 mph, making it the fastest production Corvette ever. The Grand Sport coupe and convertible share the LS3 engine with the base model coupe and convertible, and can be had with a 6-speed manual or automatic transmission. The Grand Sport comes standard with wider wheels and tires, a revised suspension, extra cooling, larger brakes, and specific manual gear ratios.
