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.

Donnie Campbell from Lewis is on a mission to become one of Europe's fastest amateur drivers, so he's entered his Subaru Impreza into a major speed trial - Ten of the Best. He's souped up the engine to 1000 bhp - but is that enough to qualify? Fiona Mackenzie returns to Air an Rathad as this week's guest reviewer. She's always been a fan of the BMW brand, but will a spin around Perthshire in an Audi A3 Sportback change her allegiance? Ian Mackenzie from Stornoway is this week's Petrolhead, driving his Firenza Droopsnoot, and on the Wacky Race track the team are having a 'smashing' time!
