Just thought I'd share this, unfortunately didn't get a picture as iPad died with the missus watching films the whole journey.
Anyway I drove 283 miles to visit my parents last night and I got 41.4 MPG! From lingfield to middlesbrough on the A1/A19 70-80mph the whole way.
I'm really chuffed with it and I only used just under half a tank of petrol
What are you guys getting with mapped cars?
