The main challenge is simply a lap-time shoot-out of the full GP circuit and the organisers have already signed up companies as diverse as Hartge, Techart, Litchfield Imports and AMD for the competition. There's also a quarter-mile drag race including honours for fastest 0-60mph and 0-100mph times, and the Melbourne Loop will witness a spectacular drifting challenge. evo's Richard Meaden will be driving a 500bhp Subaru and we're also hoping to bring a couple of surprises along to slug it out with the mega-horsepower entries.
