This is it. After years of development and challenges getting it to a road-ready state, the production-spec Mercedes-AMG One hypercar has finally been revealed in full.
This is basically a Formula 1 car for the road. And yes, it has been done before, in the 1980s and ’90s. But this is 2022, where we have lots more rules and regulations governing what a road-legal car can and can’t do. In other words, it’s amazing that AMG seems to have pulled it off in this day and age.
At its heart is a 1.6-litre turbocharged V6 hybrid engine. This package is similar to the current Formula 1 power unit, featuring an electronically-assisted turbocharger that runs up to 3.5 bar of boost (50.7psi), with gear-driven camshafts and pneumatic valve springs helping the V6 rev to 11,000rpm.
An electric motor mounted at the crankshaft provides a 120kW boost, while two 120kW electric motors help turn the front wheels. Another 90kW e-motor helps the turbocharger spool up, although it does not directly power the wheels. But all up that’s 450kW of electric motors within the vehicle.
Combined and running at its peak, the package produces a colossal 782kW (1063hp). Surprisingly, the One can run on electric power alone (as a front-wheel drive) for a distance of about 18.1km. That’s thanks to an 8.4kWh battery.
In terms of performance indications, Mercedes-AMG says it’ll do 0-100km/h in 2.9 seconds and 0-200km/h in 7.0 seconds. To achieve 0-300km/h it needs 15.6 seconds, which is just insane. The One also offers a top speed of 353km/h and presents a fuel economy average of 8.7L/100km (under the WLTP cycle).
Mercedes-AMG has developed a brand new seven-speed automated-manual transmission for the One, featuring four shift rods and a four-disc carbon fibre clutch. It says the transmission is specifically designed for the high-speed engine, and it is light in weight and comes integrated at the body-in-white stage of the build.
Other highlights, of which there are many, include multi-link suspension in a push-rod layout with coil-over springs and dampers, forged aluminium wheels with a centre-lock design (just like a racing car), and carbon-ceramic brakes with six-piston front and four-piston rear calipers.
Drivers can select between six main drive modes which alter the powertrain characteristics, aerodynamic platforms, and suspension tune. These include Race Safe (a general hybrid mode), Race (hybrid with engine running to optimise charge), EV (all electric), Race Plus (lowered suspension, active aero), and Strat 2 (for racing tracks only with maximum settings). There’s also an Individual mode allowing owners to configure different parameters.
Mercedes-AMG is planning to produce just 275 examples of the One, and all have apparently be sold. The hypercar will make its dynamic debut at the 2022 Goodwood Festival of Speed which takes place from June 23-26. See below for the full specs:
