We've already given you all of the details on the new 2012 BMW 3-Series, including our first drive impressions from Spain, but if you haven't yet gotten familiar with BMW's newest midsize, this video from the Detroit Auto Show gives you the highlights.

Along with the three new main trim lines (Modern, Luxury, and Sport), and a new exterior look, the 2012 3-Series packs a new turbocharged 2.0-liter four-cylinder engine good for 240 horsepower and 260 pound-feet of torque. Paired with the new eight-speed automatic transmission, it's capable of both better performance and better gas mileage than the previous 328i's 3.0-liter inline six-cylinder.
