In this Chasing Curves video, a heavily modified McLaren 720S was taken deep into the mountains along US129—but instead of heading toward the famous Tail of the Dragon, the drive went in the opposite direction. What followed was a surprising discovery: a road that may rival the Dragon in excitement, offering wide, flowing corners, fast straight sections, and a surreal landscape blanketed by invasive kudzu vines.
This particular 720S is far from stock. Its custom-built 4.0-liter engine is engineered to handle up to 2,000 horsepower and currently produces around 1,000 wheel horsepower. The setup includes Pure 1300 turbochargers, 1050x fuel injectors, and a dual-pump fuel system, complemented by 3.5-inch titanium downpipes, inlets, and exhaust. Power delivery is optimized through an M Engineering ProTune calibration.
Performance upgrades extend beyond the engine. The car features a 765LT transmission and upgraded clutches, along with a 765LT suspension conversion paired with a one-off, custom-tuned hydraulic system—the only example of its kind. Braking performance is also enhanced with 765LT brakes.
