Future BMW i8 in Extreme Cold Test Video

I8 expected that 2013 will be a 2 +2 coupe with hybrid battery and my faith in the butt very long. You can see the video, the i8 is not silent and sound is not really smooth. However, it promises a 0-100km / h in 4.8 seconds with 2 electric motors placed on each axle and a 3 cylinder diesel 1.5-liter, all offering about 330 hp and improved fuel economy. However, rumors suggest that this 3-cylinder heat would be replaced by a 4 cylinder.
