Calum Iain heads to the borders to see his rally driving buddy Robin Parkinson in a rally with a difference. These superfast 4x4 cars are designed for off-road racing and the course through the Galloway Forest is one of the toughest Calum Iain has ever come across. Many of the cars and drivers struggle to cope with the tough race conditions. The lucky ones are those who manage to complete the race. Meanwhile, Louise joins a band of VW campervan enthusiasts on a more leisurely tour and discovers the amazing history of this iconic symbol of the 1960's counter culture movement. BMW enthusiast Fiona test drives a 5 series with a difference and asks if the new Gran Turismo saloon, can be all things to all people. And on the Wacky Race Track our presenters are ready for their next challenge. What will they be racing this week?

This week the Air an Rathad team reveal how to cut the cost of motoring in this new age of austerity. Murray investigates a cheaper alternative to the regular diesel you buy at the pumps, while Fiona meets an island man who, for the past five years, has been running his van on fuel which he makes himself for just 20p a litre! Over the past decade, the UK has gone from being one of the most expensive places in Europe to buy a new car to one of the cheapest. Murray searches out the best deals and comes up with the two cheapest new cars available in Scotland. He calls in Louise's help to put them through their paces. And we also enlist the help of a Highland family to test drive one of the most affordable family cars on the market.
