Yeah the battery is far more spritely aswell such that the car tends to feel peppier in warmer weather. Doesnt really cool off but Ive only seen the battery get as high as 38C. Tend to park at work with windows open a little and sunshade in.
Main benefit from warm weather for MPG is the warm up to reach 90C coolant is no more than 2 miles and the higher Inlet air temp makes the lean burn mode piece of cake to use. I still probably drive a little too fast to make a big increase in the time in lean burn though. My 37mile drive to work has something like 10 roundabouts aswell. Brillant car for penny motoring... Im still in 45p per mile for business use of my LTD co so if you take the 20% corp tax reduction I 'make' 9p per mile.... and over the last tank the fuel cost was 8.4p per mile.
