A corvette has more HP, more displacement and gets around 28mpg.
I am nto saying the engine is not great but it sure is not for its efficiency

you get 30 hwy and 20 city with an N54?? are you pulling my leg?
two and half years ago I got a loaner 335i (n54) with 4000 miles for a week when my e46 M3 was in for service. i was only able to get about 22 mpg combined..(daily driving, with the same route and behavior when compared to driving my m3s)
considering it's a FI engine, it's not that different from my S54 engine (avg. 19 combined). My S65 engine averages about 17 mpg combined.
