Earlier this week I read something about the RS4 actually getting better mileage than the S4 despite it's increased horsepower/torque. How is this possible? I have this feeling I'm missing something obvious but it seems that people's real life mileage runs 20 to 25 on the freeway and 15 to 20 around town... not that it's worth mentioning but they claim 10 to 13 in stop and go traffic. Can anyone explain this to be me please? Thanks ahead of time.

RS4 is a hybrid.

Direct injection is about 5-10% more efficient than standard manifold injection. It's very easy to get 23 mpg on the highway cruising with the RS4.

yep...it's even been better than my B7 S4 tiptronic, which supposedly is better than the 6spd S4.

let me guess, it burns petrol AND rubber? lame lame lame

so the s4 doesnt have direct injection? i definitely missed that. thanks!

TonyBenino

wow, glad to know it wasnt just some stupid rumor.

because I never use the upper gears anymore...

All new V8 models are getting direct injection - and some Audi models have it now besides the RS

because the RS4 is an FSI engine, but the B6 and B7 S4 engine isn't. So the RS4 had direct injection and lean burn, but the S4 has neither.
