Tom – Taking the channel tunnel it is 1302km (809miles) non stop from Cambridge to Biarritz. 6 fuel stops and 209.79L. Therefore 17.53mpg 0.16l/km at 80 – 100 km/h. Its a good thing fuel is cheaper in Asia!

I still have no heater and it was below freezing  inside for most of the trip. It turns out though that no heater definitely helps you stay awake!
