I have a question about CAFE standards. As someone mentioned, it is virtually impossible for a car manufacturer to design or re-design a car within 2 or 3 years to meet tighter CAFE requirements. However, can't they just eliminate the offering of higher HP engines?
Let's look at the BMW 5-series. BMW has always offered a base 6-cylinder engine, an upgraded V8, and even a supercharged V8 (for the M-version) of the 5-series. How does CAFE treat those different versions? Is the average MPG based on how many cars of each engine are actually sold? If BMW wanted to instantly improve CAFE mileage, I would think they could sell just the 6-cylinder engine and stop offering the V8s (of course, the market may not like that).
