Forums are great if the info posted is correct, but Martin I am not sure where you get yours from but you could not be more wrong Cold air improves the engines power output for a given throttle opening, it therefore improves efficiency in cold weather. Secondly wet surfaces unless it's glue or tar etc give reduced grip and therefore reduced rolling resistance And return better mpg, this further improves mpg as most tend to drive slower due to reduced grip.

Hi Just took delivery of an F-Sport today, drove 110 miles, with a mixture of town and country roads, no duals or motorways. I had full air con and cooling seats. I gave it the gun a few times and dabbled with some Eco driving. The tank I assume was full, it's still showing full with a range of 618 miles and an ave of 52.3mpg. I am pleasantly surprised, it beats my 15-30 disco 4 on the same trip.
