Linda, Donnie and Murray are back where they belong, in the driving seat. They're test driving the newest cars on the market, taking part in car club rallies and thrashing old bangers round the race track. Air an Rathad is back with a brand new series! Linda journeys home to North Uist in a very exclusive motor - the Rolls Royce Wraith, while Murray puts an old Land Rover through its paces at a quarry near Huntly. Petrolhead Paul Mackie takes his very exclusive DeLorean out for a spin, while all three presenters are back on the Wacky Races track competing for their name on the Air an Rathad Cup. Murray won it last year, and he's keen to defend his title!
