The McLaren P1 is breathtaking. It's technically insane. It's fast. And it's very, very powerful. Probably more powerful than we know.

HammerheadFistpunch kicked off a rather lengthy discussion about what causes fire from the exhaust. But he stepped upon one point we probably haven't thought of before.

Alternate theory - the car generates sufficient downforce to extract fire and brimstone from the very depths of hell and uses the exhaust as a dumping point.

Another reason you're going to want to stand a ways away from it when it's going quickly.
