Mercedes-AMG’s preparing to put a F1 engine in a road-legal hypercar (£2.4 million value) are developing well, with its 1000bhp drivetrain revealed to the press at the Nurburgring 24 Hours last weekend.
Uses a deeply modified version of the electrically turbocharged 1.6-litre V6 housed in the Mercedes-AMG W08 EQ Power+ race car, as driven by Lewis Hamilton and Valtteri Bottas in the 2017 F1 World Championship.
Autocar reports the upcoming four-wheel drive AMG road car also features both an MGU-K (motor generation unit – kinetic) and MGU-H (motor generation unit-heat) functions as part of a complex Energy Recovery System (ERS) mounted around the mid-mounted petrol engine at the rear.
The combustion engine and the rear-mounted electric motors provide drive exclusively to the rear wheels. Featuring is a an eight speed automated manual gearbox that acts as a structural bearing element within the driveline at the rear of the engine, where it supports an intricate five-link rear suspension featuring pushrod style spring and damper units.
Formula 1 engine and tech
Talking about the F1-derived powertrain, Moers told Autocar: “We have to change something for sure. 3500-4000 revs is not that great for the road.” He added: “The red line is over 10,000 even in the street legal car.” In fact, Moers has since confirmed that the Project One will be able to rev to 11,000rpm.”Our F1 engine is far more durable than many people expect, and if you look at the load it must take in an F1 race compared to how it’s likely to be used in a street-legal machine, you can see it’s going to have a lot less work to do.” The unit is expected to have more power than that used in an F1 car.
“I can tell you we will be using an ‘AMT’ (automated manual transmission) because there’s no twin-clutch gearbox capable of working with an engine that revs to 11,000rpm,” said Moers. “We will have four electric motors – one for each front wheel, one on the crankshaft and one on the engine turbocharger. We will use the same ‘perfomance’ battery cells as the F1 cars, which have advantages and limitations; but we will still be able to deliver 30km of EV range. And our target for kerbweight is 1300kg ‘DIN'”
