2006 CORVETTE: Z06 HITS THE GROUND RUNNING; NEW SIX-SPEED AUTOMATIC AVAILABLE FOR COUPE AND CONVERTIBLE
Model year 2006 will always be known as the year the 505-horsepower* Z06 was let loose on the sports car world. With its 505-horsepower (377 kw) LS7 7.0L engine, racing-bred suspension, hydroformed aluminum frame and unique bodywork, the Z06 is the fastest, most technologically advanced production model in Corvette’s 53-year history.
Performance enhancements also are found on ’06 Coupe and Convertible models, with the availability of a new electronically controlled 6-Speed Paddle Shift transmission with automatic modes. The transmission has three driving modes – Drive, Sport and Paddle Shift – and a wide, 6.04:1 overall ratio that enables a balance of stirring acceleration and excellent fuel economy.
Other changes for 2006 Corvettes include a new three-spoke, 370-mm-diameter (9.4 inches) steering wheel. The wheel is smaller in diameter than the previous steering wheel, allowing the driver to maintain a “tighter” feel on the wheel and help improve turn-in response. The three-spoke design is characteristic of a sporty design that is being implemented in other performance-oriented Chevrolet vehicles.
6-Speed Paddle Shift automatic details
The new electronically controlled 6-Speed Paddle Shift automatic transmission is one of the most technologically advanced transmissions in the industry, featuring clutch to clutch operation, manual control shift operation and an integrated 32-bit electronic controller. A wide, 6.04:1 overall ratio helps deliver exciting acceleration performance along with excellent fuel economy.
The six forward gears have smaller “steps” between them, which enhances the feeling of performance and smoothness. The smaller steps also enable a steep, 4.02:1 first gear, which provides an improved-performance launch feel when compared with the previous four-speed automatic’s 3.06:1 first gear. There are two overdrive gears: a 0.85:1 ratio in fifth gear and a 0.67:1 ratio in sixth. The final drive ratio of Corvette models equipped with the new transmission is 2.56:1.
Technological sophistication is exemplified by two electronically controlled automatic modes, Drive and Sport; plus manual Paddle Shift. The Drive mode follows a specific shift schedule of predetermined shift points, while the Sport mode enables Performance Algorithm Shifting (PAS). PAS modifies shift patterns when performance driving is recognized by the controller. The Drive mode optimizes shifts for smoothness, while the Sport mode enables firmer shifts for better performance. With the Paddle Shift mode, gear changes are made with manual control paddles located on the steering wheel.
The performance and functions of the six-speed paddle shift transmission with automatic modes are guided by an integrated controller. The controller is located inside the transmission, reducing complexity. A new 300-mm torque converter, new rear bell housing, new driveline support and revised-length driveshaft also support the transmission’s integration into the Corvette.
