Air An Rathad

Fiona gets lost on Harris and Murray is all at sea when the presenters two go head-to-head in an intriguing challenge. Murray has come up with a test to find out if a more ancient form of transport could be a faster way to get around the Western Isles than a super-fast boy racer's car. Louise tops up her racing skills with one of Knockhill's top instructors and gets the chance to live her dream behind the wheel of a Formula One car. How does she perform in the wet? Calum Iain has never been happier as he puts the brand new top-of-the-range Jaguar XJ Supercharged V8 Supersport through its paces. He also discovers levels of comfort previously unknown to him in a Mark 2 Escort. And we welcome Wacky Races - a brand-new feature in which our presenters battle it out on the race track, competing against each other in a driving challenge with a twist.

Calum Iain heads to the borders to see his rally driving buddy Robin Parkinson in a rally with a difference. These superfast 4x4 cars are designed for off-road racing and the course through the Galloway Forest is one of the toughest Calum Iain has ever come across. Many of the cars and drivers struggle to cope with the tough race conditions. The lucky ones are those who manage tocomplete the race. Meanwhile, Louise joins a band of VW campervan enthusiasts on a more leisurely tour and discovers the amazing history of this iconic symbol of the 1960's counter culture movement. BMW enthusiast Fiona test drives a 5 series with a difference and asks if the new Gran Turismo saloon, can be all things to all people. And on the Wacky Race Track our presenters are ready for their next challenge. What will they be racing this week?

Fiona checks in at Stornoway airport where her estimated flying time is just 12.5 seconds. Calum Iain takes on the Catterline Cartie Challenge and Murray discovers the innovative technology of the new Mercedes E-Class Estate.

This week the Air an Rathad team reveal how to cut the cost of motoring in this new age of austerity. Murray investigates a cheaper alternative to the regular diesel you buy at the pumps, while Fiona meets an island man who, for the past five years, has been running his van on fuel which he makes himself for just 20p a litre! Over the past decade, the UK has gone from being one of the most expensive places in Europe to buy a new car to one of the cheapest. Murray searches out the best deals and comes up with the two cheapest new cars available in Scotland. He calls in Louise's help to put them through their paces. And we also enlist the help of a Highland family to test drive one of the most affordable family cars on the market.

There's a retro feel to this episode when we meet up with the Western Isles Classic Car Club. Tensions are frayed when Fiona and Murray get lost on Lewis on the club's 10th anniversary Treasure Hunt. They discover that you don't have to be driving the fastest car to win this 'tortoise and the hare' style race. At a motor event with a difference, Louise meets the audiophiles who spend much more on their car stereos than they do on their cars. Murray lowers the roof on the new convertible Fiat 500 Pop. At first he's convinced it's been designed with the female driver in mind, so he decides to find out if it's just as much fun to drive for blokes like him. Also, there's more chaos in this programme's Wacky Races as our presenters race towards the chequered flag.

The team joins forces with Central Scotland's police advanced driver training team. Louise is given a one to one lesson on police driving techniques and gets the chance to switch on the blue light for a high speed chase along one of Scotland's busiest motorways. Fiona is on Harris where she drives a VW Beetle which can outrun a Porche 911. When she meets the man who built the car's super charged engine, she's in for a big surprise. He turns out to be the ex drummer of one of her favourite punk rock bands, the Buzzcocks. And somehow, Fiona also finds the time to put the stunningly good-looking Ferrari F430 F1 Spyder to the test...nice work if you can get it! Our presenters get a taste of real work in this week's Wacky Races, but are they up to the job in hand?

Air an Rathad's very own rally driving presenter Calum Iain, has just won his first race of the season. Will his impressive form continue on the tough forest tracks of Argyll? Overnight rain has soaked the course. Calum Iain couldn't have asked for more favourable conditions. And by way of a contrast, what will he make of the latest version of Toyota's silent running, petrol hating, Prius? Calum Iain puts this part electric, part petrol, hybrid through its paces. After the Model T Ford and the Mini, could you name the next best designed car of all time? Louise discovers the answer when she takes one of the most innovative cars ever, for a spin along Royal Deeside. It all gets a bit wet in this week's Wacky Races, as our presenters battle it out on the track.

In the last of the series, Calum Iain has a taste of the Big Apple...in Inverurie! There he meets up with the Moray Muscle Group, a bunch of people who are obsessed with classic American 'muscle cars'. He even gets the chance to flex his biceps behind the wheel of the original 1950's Capri. Fiona meets some of the fastest Go-Kart drivers in the UK at the Grampian Kart Club. She doesn't take much persuading to strap in and burn some rubber on the clubs super fast circuit near Banff. Fiona also takes a close look at the sensuous curves of Peugeot's RCZ. Will it mark a return to form for the French company, after several years of lack-lustre models? And it's the final race of the series - who will win the coveted Wacky Races Cup? You'll have to watch to find out!
