More muscle for Corvette

2007-05-07 09:47
The ultimate American muscle car just got better. Check out the revised Chev Corvette with plenty of new kit, including a new 321 kW 6.2-litre V8. The performance Z06 has also received some attention.

The new V8 engine will be standard issue on the coupe and convertible models with claimed outputs of 321 kW at 5 900 r/min and 575 Nm of torque at 4 600 r/min. And optional two-mode exhaust system pushes this up to 325 kW and 580 Nm - goodness!

This V8 uses an aluminium block with reinforced bulkheads and new pistons designed particularly for performance at high engine speeds. The combustion chamber and exhaust ports have also been redesigned for better flow, while the camshaft timing has been revised too.

The optional two-mode performance exhaust system uses vacuum-actuated outlet valves to give the Corvette a more aggressive exhaust note under full acceleration.

Regarding the six-speed manual and automatic transmissions, the gearboxes have have been improved with more definite changes with the manual and quicker shifts on the automatic.

Inside the cabin, all models feature a new instrument panel with metallic surrounds for the gearshift and cupholders, metallic sill plates, two-tone leather finishes, and a longer list of standard features. These include a navigation system, satellite radio and auto dimming rearview mirrors.

The exterior appearance has been slightly tweaked with a more tapered rear end aiding high-speed performance. The new rear end also has a centrally-mounted exhaust outlet.

On the road, three suspension settings allow drivers to choose the driving setup that best suits their driving style. An optional Magnetic Selective Ride Control suspension features dampers that are able to detect road surfaces and adjust the damping rated to suit these surfaces.

The race-inspired Z06 has also had its exterior enhanced with several go-faster bits and a 7.0-litre V8 that produces 377 kW at 6 300 r/min and peak torque of 637 Nm at 4 800 r/min. These performance credentials allow the car to sprint from 0 - 100 km/h in under four seconds and hit a top speed of 319 km/h.
