Ariel Atom V8 pitted against Citroën DS3 racer and BMW HP4 superbike
It's still a fun theoretical battle. The 550-kilogram Ariel Atom brings a 3.3-liter V8 with 475 horsepower, 268 pound-feet of torque and a 748-hp-per-ton ratio. The engine-restricted, 1,300-kg DS3 Rallycross rocks a 2.0-liter four-cylinder set for the day to about 560 hp, 600 lb-ft and – because of its variable boost – anywhere from 454-577 hp-per-ton. The HP4, naturally, does the most with the least, its 169 kg hauling a 1.0-liter engine with 163 hp, 83 lb-ft and a screaming 757 hp-per-ton.
It's a shame the weather didn't allow the entrants to show all they could do, especially the two-wheel-drive Atom. Nevertheless, it does demonstrate how critical the amount of available traction is to get the most from high-performance machinery, and there's lots of launch-controlled action and a winner crowned in the video below.
