One way to test out a driver to see if they're any good is to try and gauge how well they know their car and the track it's on. Even the most competitive of drivers would pride themselves on knowing a track well enough to pull off a blistering lap time while trying to multitask and explain complicated concepts. After all, there's a reason why on Top Gear, the Stig was the quiet one while the less competent drivers were the presenters.

This time, Jason Fenske of Engineering Explained goes for a lap around the Global Rallycross course in Los Angeles and attempts to explain a bit of the components that give the car its pedigree.

So the complex track is already chosen, what about the car and driver? In this case it happens to David Higgins, brother of rally legend Mark Higgins, in a 2.0-liter four-cylinder Subaru STI that's had its turbocharger cranked up to an unsustainable (as in the engine will probably blow if you daily drive it) 45 psi. The result is an impressive output of 580 hp and 661 lb-ft of torque being channeled to all four wheels through a six-speed sequential gearbox. All it takes is 1.9 seconds for the Subie to hit 60 mph from a dead stop, meaning that if Fenske really hopes to divulge every bit of information pertinent to the rally car in the time it takes it to make one lap around the circuit, he'd better hurry.
