Had a hard blast down to Gatwick in very early hours!
Main reason for that was a diversion at the Bracknell/Ascot junction which meant I had to go back down the M3 to next junction of and back on again.
Ummmmm I can say what speed I did to catch up time again but the mpg only went down to 27 which I was very surprised with!
Seems faster I go the more efficient the car is!
