The biggest single factor in fuel consumption is how YOU drive. Most cars have a large variance depending on how they are driven. It is FACT that most people struggle to mtach the optimistic figures quoted by the Gov agencies and manufacturers, and withn the confines of real world driving, the MPG YOU achieve may or may NOT come close to those claimed.

That said, there will be some cars that are more or less fuel efficent, whilst operating with similar performance.

I would use the smiles per miles as the ultimate decider, UNLESS fuel IS THE defining factor in the equation.

I suspect for many, cost of fuel per mile, whilst not irrelevant, is not high on the list.

I am sure they will rate the smiles per mile, and the linear power delivery as more important. Its like, if you have to ask how much, you cant (or dont) want to afford it. Simple.
