One of the leading international teams headed for the World Time Attack Challenge has issued a warning to its global rivals. The Sierra Sierra Enterprises squad says it has put its Evo 8 through a major development program in search of extra single-lap pace.
“The car has undergone a very complex engine R&D program with Cosworth Racing in recent months, with weekly updates that have raised output by more than 75 kilowatts,” said team manager Richard Raeder.
“At the same time we’ve put the car on a detailed weight-loss program to improve the power-to-weight ratio and spent a lot of time developing the suspension, braking, aero and overall handling.”
The development program resulted in the Sierra Sierra Evo breaking the long-standing lap record at Buttonwillow raceway in California last month – former open-wheel and sports car racing champion David Empringham setting a time of 1min 43.346. That bettered the previous time of 1min 43.523 set by the world famous HKS CT230R in 2007.
Raeder says the Sierra Sierra team’s ambition to build the fastest time attack car in the world will clearly be put to the test in Sydney.
“For a professional race team like us, with a background of Toyota Atlantic racing, it’s not enough to just compete in the States – so we’re coming to Australia to race the best from Japan.”
“The Challenge is an exciting concept,” says Raeder. “I like that the cars will be competing on road-legal tyres rather than pure racing slicks – it adds grass-roots feel to the event.”
