New presenters Linda Macleod and Donnie Mackay join old hand Murray MacLeod in a new series of Air an Rathad. Donnie joins members of the Highland Car Club on their summer rally through the Great Glen, while Murray takes a spin in Vauxhall's new sports car, the Cascada, to Callanish. Petrolhead Eilidh Mackinnon, from Skye, shows off her Mark 4 Golf, and over in Fife on the Wacky Race Track, all three presenters search for the superhero inside themselves.

In this programme, Murray is on manoeuvres with the very latest army vehicles, including the new million pound Foxhound, while guest reviewer, Eilidh Davies, test drives the Seat Mii. The Mii has some exciting new safety features, but when Eilidh tries them out, things don't go according to plan. This week's Petrolhead is Mark MacPherson, from Tong, who shows off his customised Corsa, and there's more fun and games as the team get wet on the Wacky Race track.
