To celebrate 50 years since the brand's first Bathurst win, GM Holden has developed a futuristic 'Time Attack Concept' car that will take on a simulated lap of the famous Mount Panorama circuit.
The wildly-powerful concept has four electric engines pumping out 1340 horsepower and 3240 Nm of torque, fitted to a carbon fibre and Kevlar body.
The predicted performance figures are a 0-100 km/h time of just 1.25s, a top speed of 480 km/h and a Mount Panorama lap time of 1m29.30s.
To put that into perspective, the current outright lap is a 2m01.567s set in a GT3 car, while Jenson Button lapped the circuit in 1m48s in a McLaren Formula 1 car at a promo event back in 2011.
The Holden concept will actually be built, but only as a 3D printed model, not a functional car.
“The cessation of motor shows in Australia left a hole in our automotive culture in some ways and we lost a forum to showcase our passion and creativity to the Australian public with physical concept cars," said Holden's design director Richard Ferlazzo.
"However, with the realism and detail achievable through modern technology, I felt we could still deliver uniquely Holden concepts via virtual technology and digital media.
“Automotive design and engineering remains a core strength and competitive advantage for Holden and for Australia. The Time Attack Concept racer is an illustration of how we can utilise cutting-edge technology to develop transportation solutions for the future."
