Ann am prògram na seachdain seo tha seann charaid Air an Rathad, Calum Iain MacCoinnich còmhla rinn - a' dèanamh coimeas eadar dà chàr chliùiteach - am Ford Escort RS200 agus an Nissan GT-R. Agus tha aonfhear gu sònraicte a' còrdadh ris - ach cò am fear? Tha Murray a' feuchainn dhan chàr dealain aig BMW, an i3 agus tha e a' còrdadh ris.

Tha e ga thoirt air cuairt ann an Obar Dheathain agus sna sgìrean mu thimcheal gus am faic e mar a tha e sa bhaile agus air an rathad-mhòr. Tha an Ceann-Connaidh, Niall MacLeòid measail air BMW, ach bidh an 318is aige ag òl a' chonnaidh. Thall ann an Crail, tha Donnie, Linda agus Murray a' gabhail dha anns an dàrna fear mu dheireadh de na Rèisean Craicte anns an t-sreath. Am bi cùisean teann aig an deireadh?

In this programme, Air an Rathad veteran Calum Iain Mackenzie makes a guest appearance - comparing two iconic cars - the Ford Escort RS200 and the Nissan GT-R. He has a firm favourite - but which is it?

Murray test drives BMW's all-electric i3 and is impressed with it's performance. He takes it for a spin in and around Aberdeen to see how it handles both in the city and on the dual carriageway.

Petrolhead Neil MacLeod loves his BMW, but his 318is drinks petrol. Over in Crail, Donnie, Linda and Murray are going all out in the penultimate Wacky Race of the series. Will it be a close finish? Show less
