Join Wacky Race commentator Alec MacDonald for more fun and mayhem from the Air an Rathad team with this Wacky Races Special! Your favourite funny features from series five handily combined in one programme - now that's entertainment!

Old friend 'Rollover Roy' is competing in the Speyside Rally with a new car and a new navigator - can they keep the car upright this time? Fiona enjoys taking a furry friend for a spin in the new Mini Roadster, uber cool but a tad chilly for the Scottish climate! Cudig's final classic of the series is the Landrover, a reliable workhorse loved my millions; and it's a thrilling end to Wacky Races - if you think it's a done deal, think again!

Fiona is in the Cairngorms in search of the Abominable Snowman, helped in her quest by the Skoda Yeti. Murray is practising his handbrake turns in Ashaig as he takes part in the Skye Rally Club's Auto Test, and Cudig has the team reminiscing over days gone by as he shares this week's classic - the Bedford CA Van. Calum Iain has the scent of victory in Wacky Races, but will pride come before a fall?

It's the Air an Rathad Energy Special this week, as Murray drives one of the very first commercial hydrogen fuelled cars in the UK - a Hyundai IX35. How does it compare to other renewable fuelled cars on the market? The Arnold family put the all electric Vauxhall Ampera to the test - it's won 2012 Car of the Year, but is it to their liking? Wacky Races also goes green as the team try to catch the wind, and Cudig's classic reminds us of the old days when petrol was 16p a litre - and the Ford Cortina was the car to be seen in!

Murray takes on a real heavyweight - eight tons of raw power - as he learns to drive The Grizzly, an American Monster truck. Fiona is turning heads, and making friends, as she drives the quirky Renault Twizy around Glasgow. Cudig's classic is also a head turner; good looking, popular and super handsome, the Rover 2000 was *the* car for the man who had 'made it'. And in Wacky Races, our bold heroes have lost the plot - can their Doric SatNav help them get back on track?!

There's a lot of burning rubber in this episode, as Calum Iain heads to Crail for a master class in Drifting. And we stay in Crail for more fun and frolics in Wacky Races. The scores are all equal so whoever wins this next challenge is setting the pace! Murray is on home ground as he test drives the Volvo XC60 in Lewis. Can it get him from A to B as comfortably and safely as he would like? And Fiona's very happy with Cudig's classic selection- it's the ever popular MG.

Fiona is in Fraserburgh at Crimond Racewayy, and the stock cars are smashing their way around the track. She takes part in her very first Ladies race - and it's not for the faint hearted! Calum Iain is behind the wheel of a hot hatch from France - the Citroen DS4. Is it l'amour or a lemon? One thing's for sure, he'll tell us what he thinks of it! Cudig remembers the Vauxhall Chevette - one of the first superminis - but have they stood the test of time?

One super fast sports car - the Lotus Exige S. One super excited presenter - Calum Iain. Mix them together and you have Mr Mackenzie giving it welly round the Lotus test track, breaking the previous Air an Rathad top speed by miles! While Calum Iain gets a tour of the Lotus factory in Norfolk, Murray is taking a wee run around Ballater on Royal Deeside in the World Car of the Year, the VW Up. Cudig shares another classic car choice and Calum Iain is in complete agreement - but what is it? You'll have to tune in to find out! And we're back on the Wacky Race track for more fun and games with cars long past their sell by dates...

The new series of Air an Rathad roars into view with coverage of the Solway Junior Rally. Scotland's motor sport stars of the future get fast and furious on the Borders forest tracks. Donald Neil Macleod, aka Cudig, shares his extensive knowledge of classic cars in a brand new weekly feature, while veteran presenter Calum Iain is out and about test driving the Subaru BRZ - is it a beauty ? Or a beast.
