To celebrate General Motors’ return to endurance racing at Bathurst, local wing GMSV has today unveiled a limited-edition version of the C8 Z06 Corvette, badged the Corvette Z06 Bathurst 12 Hour Specialty Edition.

Just 12 will be offered across Australia and New Zealand only – one for each hour of Sunday’s 12 Hour race, where the Z06 GT3.R will be competing.

There is no change to the 5.5-litre, flat-plane-crank LT6 V8’s power output, which sits at 636hp (475kW) in its Aussie-market configuration, backed by an eight-speed auto.

However, there’s improved performance elsewhere in the Bathurst-edition Z06, as it comes with the Z07 Performance Package – normally an optional extra for the Z06 – fitted as standard. That includes adaptive suspension, Brembo carbon-ceramic brakes, sticky Michelin Pilot Sport Cup 2 R tyres, and an exterior aero package with a high-wing spoiler.

Speaking of the exterior, the limited-edition model also introduces a new Switchblade Silver colour, and features the C8.R graphics package, engine lighting and appearance fanciness, blue brake calipers, and carbonfibre roof, mirror caps and badging.

Inside, buyers will get a numbered build plate, Competition-spec seats, two-tone blue and black Nappa leather upholstery, carbonfibre highlights, and blue seatbelts.

Those who froth memorabilia will also love that a Bathurst 12 Hour Edition print, indoor car cover with Corvette GT3.R scrawled on it, and a Corvette Racing merchandise pack including a cap, polo and jacket are all included with delivery. No New Balance sneakers, though.

The price, you ask? Yet to be confirmed, but industry experts are tipping north of the Z06’s current $336,000 price tag, which is before on-road costs.

The C8 Bathurst 12 Hour Specialty Edition is the second go at a toned-down version of a Bathurst endurance racer. The mighty Holden Monaro HRT 427 road car was conceived to homologate the Monaro 427C racers built by Garry Rogers Motorsport, which went on to win the 2002 and 2003 Bathurst 24 Hour endurance races with their beastly 7.0-litre LS behemoths. Sadly, unlike the Corvette, the Monaro road car never made it to production.
