As for the diesels, they sound pretty good, too -- particularly the 123d, which benefits from BMW's Efficient Dynamics program (Stop/Start, brake regeneration, active aero, etc). In addition to being rated at over 44 mpg (US) in the combined cycle. the 123d is gutsy. Its twin-turbocharged 1998cc diesel four-cylinder makes 204 horses -- that's over 100 hp/liter. The run to sixty takes 7 seconds and it tops out at 148 mph. The entry-level 120d also gets the Efficient Dynamics tech, but makes 177 horses. It's performance is a slight downgrade from the 123d (.6 seconds longer to 60 mph) but it beats it in fuel economy.
