Yes, and I agree with lovegroova on principle, but its not as simple as that. The more powerful torquey engine will not have to work as hard, so may well be just as easy on fuel, see what I mean?Well I'll tell you why I ask.
I am about to change from an Audi 90 Quattro 2.3l 20v to an Audi 100 Quattro 2.8l V6. On paper the MPG is about the same. Now the BHP of both cars is similar. The 100 weighs a bit more, but gives it's best torque around 2k revs lower. It's also a 'lazy engine' there as the 90 is a bit tuned.
See where I'm coming from?
Explain?A small turbocharged engine in a light aerodynamic car might be even better though....
Take a look at the fuel consumption figures of any range on the same car 3-series, Mondeo, whatever and you'll see that the bigger the engine, the higher the fuel consumption. Always. (There may be an exception somewhere but you get my drift.)Yes, and I agree with lovegroova on principle, but its not as simple as that.

So many things affect MPG, its very difficult to call. Generally speaking though, a small, naturally aspirated engine in a light aerodynamic car will be very good.
Assuming everything else is equal, he car with the most efficient engine will have lower fuel economy. If the turbo can be used to make the engine more efficient, then there you go.Explain?
(not saying your wrong btw, just curious).
I kind of agree, but sometimes the difference can be smaller than you might imagine due to not having to work the car as hard. If you have to rev the tits off it just to make it move, you'll still end up using as much fuel as in a bigger engine worked at a much gentler rate (except that with the bigger engine, you actually have some power in reserve - never a bad thing). Example, when i had my micras (shudder) my economy never matched the claimed figures because they were so gutless so i had to work them that much harder, yet in my more powerful cars, they were'nt much worse because i never had to work them as hard... if that makes senseTake a look at the fuel consumption figures of any range on the same car 3-series, Mondeo, whatever and you'll see that the bigger the engine, the higher the fuel consumption.
