A partly enforced economy run. Got an unexpected early release from work so thought I'd give the GTI a bit of a run so took the long way home. 18 miles, mostly motorway. Was intending to give the right pedal some exercise only to find the M25 a bit slow. The mpg was clocking up rather nicely so I thought I'd see how high I could get it. Settled in nicely behind a slow lorry and just as I left the M3 it was on 50.1. Peaked at 50.3 about 3/4 mile from home but some junctions knocked it back to an average 49.4 once reversed on to the drive. Not bad though! Not in any rush to repeat it anytime soon...
