I'M LOSING MY BET ON DIESELS

A few years back I made a bet with a former Director of Engineering at General Motors. I bet him five bucks that Americans would fall in love with modern diesel engines and would want them in their cars. Specifically, I predicted that diesel sales in passenger cars would reach 1 million units by 2012. He bet it wouldn't happen.

Last year I ran into him and he ruefully conceded he was probably going to lose the bet. But that was last year. Now I'm pretty sure I'm the one who's going to lose. What a difference a year makes!
