F1 engine in Mercedes-AMG Project One will have a rev limit of 11,000 rpm

No, Mercedes-AMG didn’t take the veil off its new hypercar -- the Mercedes-AMG Project One – at the 2017 Geneva Motor Show. It might because there are still some details or specs of the AMG Project One that need to be taken care of. Perhaps, Mercedes-Benz thinks it would be best to unveil its new ultimate creation at an event closer at home – the 2017 Frankfurt Motor Show.

Mercedes-AMG is set to unveil the Formula One-powered AMG Project One road-going car in its near-complete form at the 2017 Frankfurt Motor Show in September as part of AMG’s 50th anniversary celebration. However, that didn’t prevent AMG from providing more details about the Project One at the 2017 Geneva Motor Show.

In September 2016, Mercedes-AMG did confirm that a hypercar was under development, with a power output that could reach four digits. This means that the Project One hypercar – known then through an internal codename of R50 – would have an engine that could develop at least 1,000 horsepower, which is basically the same power level of the AMG’s championship-winning W07 racer in qualifying mode at Formula. In fact, Formula One was more than just an inspiration for AMG, since the engine that will become as the core of the AMG Project One is a powered-down version of the technology used in its W07 Hybrid race car.

As revealed, Project One will get a hybrid powertrain that employs the same turbocharged 1.6-liter 90-degree angle engine in the W07 car, an electric drive with three electric motors as well as an Energy Recovery System (ERS). Since the demands and running conditions of road cars and F1 racers are really different, the hybrid powertrain needs to be heavily tweaked for road use.

For example, the 1.6-liter F1 engine revs up to 15,000 rpm, which could be too much for the road. This means that the rev speed would be toned significantly, and Mercedes-AMG chief executive and chairman Tobias Moers just defined the red line. During an event at the Geneva Motor Show, Moers said that the 1.6-liter Formula One engine would be tweaked to rev up to 11,000 rpm. However, a high-revving mill – especially one developed for F1 races – isn’t exactly expected to have a long life expectancy. In fact, according to Moers, the tweaked turbocharged 1.6-liter W07 engine would be able to reach just 50,000 kilometers (31,000 miles) and after that, it would have to be re-worked to be able to run optimally.

Moreover, this engine cold be tweaked to allow it to idle at rev levels much lower than the 4,000 rpm of the original F1 unit.

AMG Project One is expected to be officially launched sometime in 2018, with deliveries set to commence in 2019. Mercedes-AMG plans to build between 200 and 300 examples, with the list of interested buyers already nearing the order limit. Each example will cost around EUR2.4 million ($2.5 million).
