Season 6 - Episode Guide

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.

Linda gets behind the wheel of a customised vehicle, the 'Dutton', but is it a car, or a boat? Could it be both? Donnie test drives an American muscle car, the iconic Chevrolet Camaro. It looks good, it sounds good, so Donnie's hoping it drives well too. Calum MacNeill from Inverness is this week's petrolhead with his Range Rover Evoque, and there's a winter sports theme to this week's Wacky Race.

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.

It's the Colin McRae rally, and we're following Davy and James Cameron from Skye in their Escort Mk2. They wrote off their car in the competition last year - will they make it to the finish line this time? Guest reviewer Niall Iain MacDonald is on the magical isle of Skye, where he finds his wish to drive a high performance car comes true; as the brand new Jaguar F Type is his for a day! Ruairidh Mackay from Inverness tells us why he loves his Subaru Impreza, and on the Wacky Race track, the team want to play with a giant beach ball, but it has other ideas.

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!

Over 70 lorries are on show at the first ever Truckness and Donnie is in Inverness to check them out. De a Nis presenter Derek MacIntosh test drives the all new Mazda 6, and the Wacky Race caravan gets its very own challenge.

Donnie has his foot on the floor on the Knockhill racing circuit, where he joins petrolheads on a 'hot hatch' day. Unlike public roads, you can drive as fast as you like on the track, with no speed restrictions! Donnie gets a masterclass on how to drive safely at speed, and enjoys every minute. Linda is test driving the new Mercedes A class in Montrose. It's packed full of new safety features and she decides to try the self park system. Can the car really park better without her hands on the steering wheel? Wacky Races gets messy this week - can Murray's lead be toppled? Donnie and Linda are determined to wrestle the Cup from his grasp. And Morven Graham tells us why her Honda Civic is the right car for her.

It's the last programme in the current series, and Murray is in Angus celebrating 100 years of Aston Martin with members of the exclusive Aston Martin Owners Club. It's James Bond's car of choice - but what about Murray? Over on the Black Isle, Donald 'Sweeny' MacSween is testing the Dacia Duster. It's a no frills 4 wheel drive for the bargain price of £9,000 - so would he buy one? Donnie is showing off his own classic Audi coupe and all three presenters give everything on the Wacky Race track in the final race of the series. The winner of the Wacky Race Cup is revealed - but has Murray done enough to retain his lead?

Donald 'Sweeny' MacSween guides us through the weird, and wonderful, world of Wacky Races in this hour-long compilation. Join him as he takes a look at all the challenges from series 6, and has a good laugh at everyone's favourite moments! Costumes, cars and craziness feature in abundance, as Murray, Linda and Donnie compete for the title of Wacky Races Champion. Who will earn the honour of lifting the cup this year?
