It’s been a little over five years since Mercedes went crazy and promised to shove a Formula 1 engine into a street legal road car. That day has finally come, and sure enough, the AMG One lives up to the hype with a hybridized F1 engine for a heart and a total system output of 1,049 horsepower, all of which is 100-percent road legal. Somehow, despite the fact that the AMG One probably shouldn’t have ever happened, AMG pulled it off. Here’s what we know about it so far.

The AMG One Really Does Have an F1 Engine

The most important component of the AMG One isn’t its wicked aerodynamics or the fact that it just somehow looks like an AMG – even if you took away the not-so-subtle logos. No; the most important component is the F1 engine, which displaces just 1.6-liters across six cylinders and can spin to as high as 11,000 RPM before it hits the redline. The engine itself was a big hurdle to overcome, as it wasn’t the easiest thing to cram into a road-going supercar. The valvetrain consists of dual-overhead camshafts, air spring valves, direct fuel injection, an electrically assisted turbocharger, and an impressively complex exhaust gas filtration system. Mercedes-AMG was able to make this 1.6-liter V-6 spit out a total of 566 horsepower (422 kW) all by itself while still meeting Euro 6 emissions standards. This is, however, just one part of the equation.

The AMG One might have an F1 engine, but that engine isn’t responsible for doing all the work. It is paired with a hybrid system that’s composed of four electric motors. Two motors are located on the front axle (one at each wheel) that produce a combined output of 322 horsepower (240 kW). The third electric motor is attached to the gasoline engine and sends 161 horsepower (120 kW)to the engine’s crankshaft. The fourth motor is apparently mixed in with a high-tech turbocharger that can produce a total of 121 horsepower (90kW). This motor can also recuperate energy from the turbo to provide more juice for the other motors. You put all of this together and you’ve got that impressive system rating of 1,049 horsepower or 782 kW.

Electrifying Performance That Only AMG Could Deliver

There really isn’t a shortage of high-performance electric or hybrid vehicles out there, but the AMG One really stands out in the pack, largely because AMG engineers left no stone unturned. The lithium-ion batteries that power the electric motors, for example, have a capacity of just 8.4 kWh, but thanks to some wicked cooling wizardry like the stand-alone liquid cooling system, battery weight is kept to a minimum as is the temperature. Even when running at full force, the battery in the AMG One runs consistently at around 45 degrees Celsius.

This low operating temperature and optimization have led to that tiny battery being able to deliver as much as 11.2 miles of electric range. The car itself tips the scales at around 3,730 pounds (1,695 kg), which is painfully close to cars like the Honda Accord with a max curb weight of 3,428 pounds. It’s no surprise, then, that the AMG One can sprint to 62 mph (100 km/h) in 2.9 seconds or from 0 to 124 mph in just seven seconds flat. AMG’s 4Matic AWD and the new seven-speed automated manual are geared so that the AMG One can cruise up to a top speed of 219 mph.

Unfortunately, AMG hasn’t revealed all the details, but watch this space as we’ll continue to update this story as new information becomes available.
