I know a lot of folks complain that their cars don't achieve anything like the official figures but I have to say I'm well impressed by Dafny so far despite not being fully run in yet. I have to wonder if it is simply that people are not driving economically, only doing very short distances so the engine is not warmed up or are selecting inappropriate engines for their typical journeys?
Her official figures are: (1.4T 100PS stop/start)
Urban: 42.8
Extra Urban: 64.2
Combined: 54
Today I did a mostly motorway 52 mile round trip from Scunthorpe to Doncaster at a steady 56mph using cruise control. This is a much higher average speed than the government test is run at (39mph) and it was not ideal conditions due to a bit a breeze. She managed a very impressive 59mpg average over the 52 miles
So far on this tank I've done 152 miles, the 52 miles of motorway plus about 100 miles of shorter local trips. The majority of those local journeys have been with myself, my wife and two kids on board (8 and 10yr olds) plus shopping etc. About 30 miles were in heavy stop start town traffic.
We averaged about 42mpg in town conditions so very close to the official urban figure despite the full load of people on board.
The average over this tank so far is 45.7mpg with 60% town driving/40% motorway. Had I done a 50/50 split of town/motorway (and without the whole family on board) the tank average would also be much closer to the official combined figure.
I think this shows that official figures can be achieved even in real world driving with appropriate engine for conditions and driving more carefully and slowing down. Congratulations to Vauxhall on a fantastic engine too.
