Air An Rathad

Donnie drives the latest Ford Mustang, which is available as a right hand drive for the first time. It's got modern multilink suspension too, so is this a Mustang, a proper drivers car, rather than a slice of Americana? And when Donnie meets up with members of the Moray Muscle Group, will they like it enough for Donnie to join them on a cruise? Linda takes the second generation Mini Clubman to the roads around Torridon to see if this Mini for grown-ups has come of age. The previous Clubman had wonky doors, which didn't make sense in the UK. Will this car's more conventional arrangement make the car more practical as Mini intended? The teams head to a kart track in their respective steeds for the latest instalment of Ralaidh na Trealaich. The Blue team's Volvo is a wobbly, underpowered estate; the Smart is a small underpowered city car. Consequently, neither is especially suited to track work. How will they get on?

Linda is learning how to be part of a rally service crew with mechanic Ian Ross. She uses the skills she learns to assist the team, as driver Mairi Ross takes part in the Rally Hebrides. She'll need to operate as smoothly and quickly as possible to ensure the car is fully prepared to tackle each stage. Murray is testing Jaguar's first entry into the competitive SUV market, the F-Pace, both on and off road. While most SUV's rarely see anything more challenging than a muddy track, Murray takes it up the Lecht ski slopes treacherous access road to see how it copes. If it survives that, how will it drive on the road? And the Air An Rathad Rally teams head to Stornoway airport for a challenge where they leave their cars behind, and move up to something a little larger. None of the teams has driven a lorry before, so when faced with a 50-foot articulated tanker who will master it the best?

Murray takes a look at the history of vehicle safety systems and how they have evolved, so that today's cars are much safer than those of the past. He is driving, or should that be being driven in, a car, that is capable of driving itself. It's a Mercedes E-Class fitted with Driving Assistance Plus, a £1,600 option that takes control of the car for you. Does Murray think it's a safe option? Donnie is driving a MacLaren 570S, a £140,000 sports car with the performance of a supercar that's designed to be used every day. Is this really a car for popping to the shops or driving the daily commute in? And it's the final of Ralaidh na Trealaich. With the Blue team leading and five points up for grabs, the Orange team can still draw level. With a wonderful trophy at stake, both teams are desperate to win.

Murray and Fiona go head to head against Donnie and Linda again, as they make their way through the islands in this Air an Rathad Railidh na Trealaich Special. Join Donald 'Sweeny' MacSween as he keeps a close eye on their antics, and has a good laugh at their expense. From Barra to the Butt, each team puts their best wheel forwards, and tries to beat the other team. Can Donnie and Linda prise the prize from Murray and Fiona's hands? Is an old Volvo 940 faster around a go-kart track than a Smart car? And exactly how many creels can you get inside either of them? Find out the answers to these, and other important questions, in this Railidh na Trealaich special.
