BMW 3-Series, 2012: Sixth generation sedan will match sibings' technology

James Raia

Now 37 years old, the BMW 3 series in its sixth generation will debut at the 2012 North American International Auto Show (NAIAS) and for the first time will include the technology currently available in its 5 and 7 series siblings.

That technology currently includes lane-departure warning system, night vision, a system to prevent the driver from falling asleep, and radar-based adaptive cruise control with collision-mitigating automatic braking.

The 2012 3 Series is expected to be powered by a new family of aluminum four-cylinder petrol engines ranging from 135 to 245 horsepower. These will include new technologies such as variable intake and exhaust-valve timing, sequential turbochargers, and direct fuel injection. The 245 hp (183 kW; 248 PS) four-cylinder may be included in US-bound models (the last four-cylinder 3 series was the 1999 318ti with a 138 hp (103 kW; 140 PS) engine). The N52 3.0L naturally aspirated I6 may be replaced by the N20 with almost equivalent output.

A hybrid version featuring two electric motors and expected fuel savings of 20 percent, will also be available in the 3 and in the pending X5 hybrid, developed in a joint venture with GM, Chrysler, and Daimler.  The new 3 Series is expected to be in sale in February
