Fresh from racing a Group C car at Spa-Francorchamps this weekend, Calum Lockie will now switch his attention to competing in the daunting Nurburgring 24-Hour race next weekend (24/25 May) in a 680bhp BMW M3.Calum has been invited to race the V10-engined M3 in the round-the-clock race by Hilux Motorsport from Luxembourg and will be renewing a partnership with Dutch ace Cor Euser. The four-strong driver squad also includes team owner Franjo Kovac and Martin Tschornia and Lockie believes that a top ten finish is within their reach."It's a very exciting car and it's going to be extremely rapid; it's potentially a front running car, and we've got four good drivers," said Lockie. "I'd be disappointed if we're not in the top 10 and we've got every opportunity to be in the top six. We'll be hitting very nearly 200mph on the main straight."Racing for the Luxembourg team is rather special for Calum as his heritage means that he is a quarter Luxembourg, a quarter Dutch and half Scots. The 24-Hour race on the daunting Nordschleife circuit is one of the most challenging races in the world. "It is an absolutely awesome race," said Lockie. "When I did it back in 2001, there were 240 cars starting in four groups of 60. You always need a little bit of luck in a 24-hour race and the weather is also a big factor at the Nurburgring. You just need to be consistent and keep clear of trouble."
