2006-2009 Chevrolet C6 Corvette Z06: LS7 Engine, Performance, and Suspension
The C6 Chevrolet Corvette Z06 has a small block V-8 called the LS7. This 7 liter, 7008 cc engine develops 505 horsepower/377 kW. The engine has a “dry sump” oil delivery system, whose purpose is to make sure the Vette engine is properly lubricated at high acceleration. This configuration also allows the engine to be situated low in the chassis.
In an effort to reduce weight, the connecting rods are
stronger-than-steel titanium. The primary structural material for the
body is hydro-formed aluminum, which also results in less weight. The
front fenders are constructed of light carbon fiber while the engine
cradle is die-cast magnesium. All of these combine for a weight of 3130
pounds or 1421 kg. The Corvette’s power-to-weight ratio is 6.2 lbs./hp
In 2007, the damping of the rear suspension was improved to produce
better drivability. In 2008, the Z06 C6 Corvette’s steering was
improved; also the car got a new manual six-speed transmission. Two
thousand nine saw the addition of Spider wheels, better software for
the Traction Control and Active Handling systems, and a change of
supplier from Delphi to BOSCH for many of the Z06’s parts.
Fun facts include the 2006 Corvette C6 Z06 being selected as the pace
car for both the Indianapolis 500 and the Daytona 500 races; the car
was also given to 2006 World Series MVP David Eckstein who could not
drive stick. (The Corvette was later re-gifted to Eckstein’s father).
