Yea here in the states the only models they offer in Diesel is the 328 Sedan and Wagon, the 535, and the 740. Other than that, the rest of the gargantuan lineup of models are all gasoline. They do have the hybrids in the 3, 5, and 7, but they aren't that common from what I've seen.
Since I live in the perpetually traffic clogged area of Los Angeles, I just throw it into Eco-Pro mode if I'm looking to save a bit on gas. Although, I couldn't resist throwing it into Sport+ mode and taking it out for a late night joy ride on some winding canyon roads out near Malibu
What a blast that was! haha
