Last week, we brought you the teaser video as to which car was the world's fastest-accelerating full hybrid. This week, Infiniti announced the winner - the Infiniti M Hybrid.

The Japanese company pitted the Infiniti M Hybrid against the Porsche Panamera S Hybrid in a straight-line drag race and the win was decisive. Now, before you go all "Yea, but it was produced by Infiniti so is the race actually fair?" take note - Guinness World Records verified the results of the race back in August, so you know it was a fair fight.
