BMW i8 prototype gives us clearest view yet of its form

The BMW i8 is still dashing through the snow on its way to a 2013 debut, and getting more revealing as it does so. The outline of the kidney grille has opened up a bit, and the outline of a Hoffmeister kink has been placed at the rear of the side windows. The door handles appear to have moved off the doors themselves to a spot behind the door shutline. It's too early to tell definitively, but the new door handle location and the lack of the once-plain gap at the A-pillar lead us to believe that the butterfly openings are gone for good.

The plug-in hybrid i8 is expected to pair a 1.5-liter three-cylinder driving the rear wheels with an electric motor driving the front, the combined output predicted at 393 horsepower and 406 pound-feet of torque. Assuming its weight really does come in at 3,125 pounds, it will have a 20-mile all-electric range, a top speed of 156 miles per hour, and get from zero to 62 mph in 4.9 seconds.
