It depends on so many factors. Driving style is the biggest factor.
Years ago I had the misfortune to be lent a 1.2 litre Fiat Punto. My usual car was a Nissan Primera 2.0, which is a 16v 150bhp unit. It usually turned in about 30mpg, or quite a lot more on a run.
This Punto, 1.2 litre 55bhp managed 24mpg on a hard run to Bristol and back (200 mile round trip)!
Why? Because I whipped its arse trying to get the bloody thing to go.
So you have to drive to the car's ability too. I'm sure my father could wring 55mpg from it on the same trip but it would take days. |
