The McLaren P1 is the epitome of hybrid insanity. Powered by a twin-turbocharged 3.8-litre V8 engine paired to an electric motor, the P1 pumps out a whopping 903 horsepower. After debuting as a concept at the 2012 Paris Motor Show, the first P1 hit the road in September 2013. Since then, a total of 375 McLaren P1s have been produced, with the last rolling off the assembly line in December 2015. When it comes to sheer hybridized power, the P1 may very well stand in a class all its own for a while to come.
