I wonder if the S5's fuel efficiency will be improved as compared to the S4...

I know, I know... something "car people" aren't supposed to worry about, but I'm curious...

social/environmental conscience thing... :-p

I figured between FSI, slight weight reduction (??? - I think we're talking one belt size, not like the subway sammiches guy...), perhaps slightly different gearing, and better aero dynamics/less drag (???)... the S5 might be a little bit less of a piggy than is the S4?

Of course, I might be slightly more heavy-footed than I should be...

...8.7l/100km, which works out to about 27 mpg. I am assuming that is hwy mpg, but don't know for a fact.

While that's not bad (and I wonder if that is based on the new testing requirements???), in comparison the 3.0 twin-turbo of the 335i is rated at 300hp, 300lb/ft (which apparently is a very conservative hp/trq rating)and gets 29mpg hwy - again, by the old measuring system.

The relatively fuel inefficiency of the Audi V6's and V8's is one of the reasons I love my little 1.8T so much! Even with Stage II mods I get ~ 30-31 mpg on the highway. That's been very nice.

P.S. I consider myself a "car person" and mileage very much matters to me! :-)

Cheers,

better fuel efficiency... I agree about small and relatively efficient but still very high output turbo-charged engines!
