Holden Torana GTR XU-1: The Downshift That Started a Racing Revolution
The Torana GTR XU-1 shattered the American muscle car theory that high performance was only measured in cubic inches. Shoehorning a 3.0 litre six from a large car into a small one was not only bold but also marketing gold for Holden, because the XU-1 just couldn’t lose in the public’s eyes. When it lost to a larger car, it was courageous. And when it won, it was a giant killer!
How the XU-1 went from inspired thought to a super successful race and rally car is a testament to the lateral thinking of GM-H management and Holden Dealer Team boss Harry Firth. And to the local company’s determination to keep its clandestine racing program alive, despite GM’s global ban at the time.
