GENERAL Motors has stuffed the latest version of its Chevrolet Corvette muscle
car with enough supercharged growl under the bonnet to scare a homegrown HSV
Featuring the same displacement as the HSV engine, the all-new donk under the
bonnet of the racetrack-honed, aluminium-bodied Chevrolet Corvette Z06 features
lightweighting technology and a more compact supercharger strapped in between
the cylinder banks.
The Z06 even features a removable carbon-fibre roof panel.
Under the bonnet, though, is a 6.2-litre “LT4” V8 featuring carbon fibre rocker
covers, 442kW of power, and 861Nm of torque. By comparison, the 6.2-litre
supercharged HSV GTS spits out 430kW and 740Nm.
But while the HSV engine likes a drink – officially it guzzles an average of
15.3L/100km – the more powerful Corvette’s eight-pot donk can shut down
cylinders to save juice.
Also helping is either a seven-speed manual gearbox borrowed from the Stingray
or an all-new eight-speed automatic transmission with paddle shifters – both of
which will fire all that performance at the rear wheels.
The automatic, basically a robotic manual gearbox, is unique in that it has
five clutches instead of the normal two developed by other car-makers.
The gearbox’s design, and the use of lightweight metals including magnesium,
means the eight-speeder is the same size as the six-speed gearbox currently
used in the Corvette, and 4kg lighter.
The Z06 carries a wider stance than its more road-friendly siblings, with the
rear tyres stretching an extra 5cm wider under specially plumped guards.
That extra grip is sent to the ground via a specially designed body that
increases downforce at high speed, and stopping it all are six-pot Brembos
wrapped around big 371mm two-piece rotors hidden behind lightweight 19-inch
alloys up front, and four-pot Brembos working on 365mm discs inside 20-inch
rims down the rear.
Three different levels of aero package will be available to US buyers,
Chevrolet says, including a rear wing with “wickerbills” – small, vertical tabs
at the edge of the spoiler that significantly increase downforce.
The US car-maker has not yet revealed performance details for the Z06, although
with features such as launch control, a competition setting for the electronic
stability control, five different torque and braking settings and an electronic
limited slip differential that can help push the Corvette around corners, it
should be fairly eyebrow-raising.
According to Mark Reuss, the former managing director of Holden and current
GM head of global product development, the Z06 should deliver “levels of
performance, technology and design that rival the most exotic supercars in the
“The Z06 leverages the engineering expertise of GM, offering the choice of two
world-class transmissions, supercar performance without supercar fuel
consumption and technologies that make it easier to fully enjoy the incredible
experience of driving it,” he said.
The Corvette will sell alongside the Australian-made Chevrolet SS as part of
the Bow Tie brand’s US muscle car line-up.
Holden has promised access to its worldwide portfolio of vehicles once it
ceases making the Commodore large car and ute, and Cruze small car range in
Australia from 2017.
The Corvette Z06 could potentially sell under the brand’s HSV badge if it is
developed for right-hand-drive markets worldwide.
