The World's Toughest Driving Tests

Châtel, France: Snow Groomer (1x5)

Air date: Mar 20, 2010

Will Mellor and Kirsten O'Brien take on the ultimate driving challenge, travelling the globe learning to drive and race the world's biggest, most expensive and hardest-to-master vehicles in a bid to find out who is the better driver. With the scores level at 2-2, Will and Kirsten are flying to France for the next examination. High in the Alps on the French-Swiss border, in the breathtaking ski resort of Châtel, they must learn to drive and then race the gravity-defying and mountain-climbing Snow Groomer, a machine packed with over 400 horse power. Mentor and judge Jean-Louis puts Will and Kirsten through a gruelling three-day training regime to prepare them for race day, when they must battle it out for victory. But after a week packed with crashes and blunders and Will dislocating his knee, it is an uphill struggle just to getting to the starting line. Desperate to beat rival Will, Kirsten has another battle to fight - her anxiety. Racked with fear, can she keep her cool and her emotions in check? So, it's all to play for in this penultimate driving test. Faced with driving their most challenging vehicle yet, Will and Kirsten know that whoever wins this week takes the lead into the final showdown.
