BMW has four-cylinder engines coming to the Z4 and 5 series lines. These engines will be turbocharged, of course. This is BMW we’re talking about here, and power is not *optional*, but required. Anytime a manufacturer can increase fuel economy without sacrificing power, I’m certainly listening.
By swapping a turbo 4 for the traditional inline six, BMW is doing just that. These engines put out the same 240 HP we’re used to, but with 30% higher torque (260 lb-ft.) We don’t yet know how much better the fuel economy is, but surely it’s going to be a few MPG’s at the least. That is, if you can manage to stay out of the boost.
Normally when you downsize to a smaller engine, you get the added bonus of saving some money. Since we’re talking about a premium German automaker, that’s not the case here. In fact, BMW is charging about $2500 **more** for their four cylinder offerings. That, my friends, is what we call chutzpah.
