It's on — a drag race of epic proportions. It's the world's fastest four-door sedan, the Tesla Model S P85D, against Australia's fastest four-door sedans, the Supercheap Auto Racing Holden Commodore V8 Supercar and the Walkinshaw Performance W507 HSV GTS. The Tesla Model S P85D rockets from 0-100km/h in just 3.3-seconds, while the V8 Supercar does it in 3.4-seconds, but weighs just 1400kg with the driver.  Strap on as we see who wins — USA v Australia.
