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!

Donnie releases his inner child as he hurtles down the Dean Road at Denholm in a cartie. He's competing in the Border Bogie Challenge, a one-kilometre adrenalin rush for all ages. The Junior competitors give him plenty of advice to keep him on the straight and narrow. Guest presenter Calum MacDonald is on a mission to find out why the diminutive Hyundai i10 scores top marks in all the car reviews. He can't quite believe it's been voted Best Car in the World and decides to test it for himself. Petrolhead Angus Ferguson tells us why he loves his Audi A3 and there's a shopping trolley on the loose in Wacky Races.
