German auto maker, BMW, unveiled its 2012 3 Series sedan at its Munich headquarters last week, giving those in attendance a sneak peak at the new version before it arrives at U.S. dealerships in February.

The forthcoming 3 Series is larger than its predecessor, but is 88 pounds lighter, says the company. And, to appeal to the green-friendly buyer, upgraded the 2012 model with green features — including an eight-speed automatic transmissions, automatic start-stop technology, and brake-energy regeneration, all of which help make the cars more fuel efficient.

It also re-introduces the BMW four-cylinder engine, which has been absent for more than a decade. Buyers will have a choice between a 328i with a turbocharged four-cylinder, generating 240 horsepower; and a 335i with a 300-horsepower in-line six-cylinder power plant.

Additionally, later next year, BMW will roll out an ActiveHybrid version of the 3 Series.
