The Corvette is a significantly lighter vehicle due to its fiberglass body.
I consistently got 19mpg or less in my 335i. They've improved the mileage a bit in newer versions, but not much. An M3 would be worse of course.
- x0054 13y agoIt's not all that different, 3,245 lb for the C5 vs 3,483 lb for the M3. This is why I used it as a counterpoint example.
- alayne 13y agoCorvettes are known for getting unusually high mpg on the highway. I always understood the primary factors to be light weight and tall gearing. V8 Silverados don't get great highway mileage, right?
- nl 13y agoThe high gearing/high torque thing is a fair point. (V8) M3s are notorious (or lauded, depending on your point of view) for being rev-hungry.
- x0054 13y agoOf course not, but for that matter nor do the V6 Silverados, or any pickup trucks in general. That has to do with wight and aerodynamic form factor, or lack there of.
- bliti 13y agoThe Corvette does have a very tall 6th gear, which allows the engine to cruise at very low RPM. It does have enough torque to overtake on 6th, though. :)
- stevenrace 13y agoYou should look into flashing your ECU. In additon to substantial power increases, there is a dramatic improvement in MPG. I can cite 35 MPG in a E60 535i (+200lbs over an E90 335i) on highway trips when in 'fuel economy mode'.
