ok so if you have 2 identical cars

one being Fwd and the other Rwd

would their be a MPG difference ?

MikeHunt79 · 3 Apr 2008 at 14:38

Yes (but they wouldn't be identical then tho...)

I thought that RWD cars had slightly higher transmission losses than FWD cars? Well I thought I saw someone mention it in another thread, so based on that I would have said the RWD would have a worse fuel consumption by a small margin.

I'd of thought they'd be virtually identical.

Or at least what you ate for breakfast would make more of a difference.

RWD tend to be heavier and have slightly more transmission losses so the RWD car should be slightly worse on MPG

Surely this is only going to be true for a front engined RWD car?

My MR2 shouldn't be suffering any additional tranny loses over the equivalent engined FWD car.

Yeah probably

Mid or rear engined cars will also have more weight over the rear wheels so if anything, and it will be marginal will have better traction, therefore waste less power spinning wheels.
