In addition to being pure chaos distilled into a motorsport, Red Bull Global Rallycross’ top-class Supercars are absolutely insane, capable of going 0 to 60 mph in just 1.9 seconds, pulling over 1.4 G in the process. Here’s what makes them so face-meltingly fast.

For one, there’s the ridiculous power-to-weight ratio. As Engineering Explained notes, GRC cars carry less than five pounds per one horsepower.

Two-liter turbocharged engines producing 600 horsepower and 650 ft-lbs of torque certainly help make the cars ridiculously quick, but some other key ingredients including all-wheel-drive, a trick limited-slip differential and series-specific tires also play a role.

Engineering Explained not only describes how it all works together, but also consults GRC driver Tanner Foust for how the driver makes it work. Spoiler: it’s a bit more than putting the car in first gear.
