The Z06 arrived as a 2006 model in the third quarter of 2005 and is the lightest of all Corvette models. The Z06 was equipped with the largest-displacement small-block ever produced, a new 7.0 L (427 cu in) engine codenamed LS7. The LS7 produced 505 hp (376 kW) and is the most powerful naturally aspirated engine put into a production car from General Motors.
In addition to the larger displacement engine, the Corvette Z06 has a dry sump oiling system, and connecting rods made out of titanium alloy. The frame of the Z06 is constructed from aluminium saving 136 pounds over the standard steel frame. Other weight saving measures such as balsa wood/carbon fiber composite floors and a magnesium alloy engine cradle were used.
The Z06’s body differentiates itself from the standard Corvette with its larger front and rear fenders and an intake inlet scoop on the front bumper. The front fenders are constructed with carbon fiber and the rear fenders contain ducts to aid in cooling the rear brakes. The Z06 weighed 3,130 lb (1,420 kg), giving it a weight to power ratio of 6.2 pounds per horsepower (3.8 kg/kW), allowing it to achieve a fuel economy of 15 mpg–
This 2006 Chevrolet Corvette Z06 is powered by a 7.0-liter Sequential Fuel Injection (SFI) Chevrolet V8 engine including a 6 speed Standard transmission. The exterior is a Blade Silver Metallic with black leather interior. Factory options include Keyless Entry, Heated Seats, Air Conditioning, Power Windows, Alloy Wheels, Power Locks, and Navigation System. Runs and drives extremely well.
