This video of the BMW i8 caught winter testing in Sweden proves a few things: The $150,000 plug-in hybrid sports car is radically short. And cold weather can do a number on your bladder.

Expected in 2013, the i8 sports twin electric motors, one for each axle, yoked to a 1.5-liter diesel three-cylinder, for total power now estimated at 328 hp. The rest of its concept targets — 0-60 in 4 seconds and change, 75 mpg, body by aliens — are expected to survive into production as well.

Thanks, Andrus!
