More on Oil and Engines

I guess the implicit part of my previous posts is that diesel engines tend to be much more efficient than corresponding gasoline engines, with many diesel cars able to reach high 30's/low 40's mpg, as opposed to the mid 20's mpg for gasoline engines.

It's clear that if we are to adopt agrofuels, then diesel seems to be an easier step in that direction. The only issue for drivers seems to be the need for that visceral feel caused by great acceleration, and in some cases auto manufacturers have addressed that problem to a significant degree, so that most drivers will be happy with the acceleration they'll get. This is already true in Europe, the home of the no speed limit autobahn.
