It was cuz emissions and they get tax credits for having hybrids and such.
The car can have zero emissions but the range is 6.8 miles
6.8 fucking miles
It's not meant to save the planet or gas, its meant to go fast. Hybrid power gives torque instantly, while gas doesn't.
Gas has to build up and gives more power over time, while electricity is instant.
A Ford Excursion gets better MPG than a Mclaren P1.
The Porsche 918 is almost double the P1 in range, but still sucks.
A Volkswagen Jetta is more fuel efficent than both of those supercars combined.
