BMW's new i-line of models is slowly making its way to market and Car Magazine claims to have ascertained all the official specs of the new i8 supercar. The plug-in hybrid model with the gorgeous gullwing doors that made its cinematic debut (in concept form) in Mission Impossible IV: Ghost Protocol will allegedly hit a top speed of 156mph and 0-62mph in 4.9 seconds. The new i8 supercar will weigh just under 3,200lbs and boast combined power figures of 393hp and 406 lb-ft of torque.
