Mercedes-AMG One specs appear in Forza Horizon 5

Details of Mercedes-AMG's highly anticipated hypercar have been 'leaked' in the latest Forza Horizon video game, providing the first look at its performance figures.

Launching as the cover car in the Microsoft-exclusive Forza Horizon 5 earlier this week, players found the hypercar available to purchase in-game alongside other offerings from Mercedes-AMG – with previously unconfirmed power and weight information readily available.

According to the game, the Formula 1-engined machine develops 654kW and 725Nm from its 1.6-litre, turbocharged V6 engine – down on the projected 735kW+ output expected from its internal combustion engine and hybrid motors.

While the powertrain's outputs are slightly down on what was first predicted, the AMG One's relatively high weight of 1695 kilograms would be down to its battery systems and extra ancillaries, adding mass for the sacrifice of power.

Just shy of a perfect 50:50 weight distribution, the game shows 49 per cent of the AMG One's weight is over the front axle, although this doesn't take its aerodynamic aids into account which would likely even things up at speed.

The One was first launched at the 2017 Frankfurt Motor Show as the Project One, launched off the back of the Mercedes-AMG Formula 1 team's three straight constructors championships, a feat it has now stretched to seven years with all cars powered by the V6 in the hypercar.

With a production run of 275 units expected, Mercedes-AMG is reportedly charging in excess of $5 million for each example, or in sports terms, around $2 million less than Lewis Hamilton's bonus every time he wins a race.
