Mercedes-AMG One debuts at long last, brings along 1,063 PS

Pinch yourself: five and a half years after the original announcement by Mercedes of a road-legal supercar with a Formula One engine under the hood, the AMG One has actually arrived.

The engineering masterpiece has 782 kilowatts of drivetrain power, which is equivalent to 1,063 metric horsepower or 1,048 U.S. horsepower. Its 1.6-liter six-cylinder engine uses a single turbocharger alongside an electric booster to rev up to 11,000 RPM. A quartet of electric motors assists the main engine and ensures that all four wheels are driven.

For a plug-in hybrid, the One has a rather minuscule battery. At 8.4 kilowatt-hours, the power cell pack lasts 18 kilometers (11 miles) before running dry. On the upside, the coupe weighs in at just 1,695 kilograms (3,737 lbs), which lets it zap from zero to 100 km/h (62 mph) in 2.9 seconds. Going from standstill to 200 km/h (124 mph) is even more impressive at 7 seconds flat, and the top speed lies as high as 352 km/h (218.7 mph).

The body comes equipped with an elaborately designed aerodynamic kit, but Mercedes does not reveal any downforce numbers for it. Included are multiple active spoilers, front fender vents, a rear wing, and more.

A look inside the cabin reveals a squared-off, F1-style steering wheel, two 10-inch displays and sport seats. Carbon fiber and leather are the main trim materials. The wheels default to a ten-spoke design, but buyers could opt for a forged magnesium set wrapped in Michelin Pilot Sport Cup 2 M01 tires.
