Mercedes-AMG has confirmed that its upcoming hypercar will be named the One for production, with the model name signifying its position at the very top of Mercedes-AMG’s road car range.
The name is also a reference to the Mercedes-AMG Formula 1 engine used in the car. The powertrain itself has undergone hundreds of hours of testing in British facilities to meet what Mercedes-AMG refers to as "the immense challenge" of making it ready for series production. The Formula 1-derived 1.6-litre V6 will produce more than 1000bhp, although the specific figure is yet to be confirmed.

Earlier this year the Aston Martin Valkyrie rival was shown for the first time on the move and in near-production form. The concept version was revealed at the 2017 Frankfurt Motor Show. The brand has now revealed that the car’s active aerodynamics culminate on its retractable rear wing, with two stages of extension giving maximum downforce in the car’s most hardcore Race mode.
Mercedes-AMG boss Tobias Moers told Autocar that the downforce generated will be “approximately half the weight of the car” and confirmed that the One will weigh between 1300kg and 1400kg. Taking the 1350kg midpoint, this would indicate that the car is likely to produce around 675kg of aerodynamic downforce. The lap time will be assisted by this, despite the car not having an enormous fixed rear wing such as that on the recently revealed McLaren Senna, which produces a maximum downforce of 800kg.
The One is being tested on "closed-off test grounds and race tracks", with images showing it on the handling circuit at Millbrook Proving Ground in Bedfordshire.
Moers has previously said it "makes sense" to build the hypercar in Britain, where the brand's Formula 1 team is based. The car's F1-derived powertrain is to be built at the racing squad's Brixworth base, but it is being adapted for road use by AMG. Moers admitted that the process is extremely challenging during a conversation at the New York motor show. "That powertrain is really complicated," he said. "It's good, but not good enough yet."
While not an immediate priority, Moers revealed that it's "reasonable to speculate" the One will eventually try to set a new Nürburgring lap record. He wouldn't be drawn on the car’s simulated Nürburgring lap time, but AMG is known to have studied past lap records in detail, including the outright record of Stefan Bellof, who lapped the circuit in 6min 11sec in a Porsche 956 sports car in qualifying for the 1000km race there in 1983. Bellof also set a race lap record of 6min 25.9sec in the same car.
