The Mercedes case. Mercedes presents its Hypercar and challenges colossal carmakers.

 

The teaser images of the car, although vague and undefined, have sparked our imagination. We know so little, at least for the time being, but our curiosity grows more with each passing day. And if expectations are very high, the price is no joke either. We’re talking about 2.8 million dollars, to start.

With this car Mercedes joins the club of Hypercars, rivalling vehicles such as the Aston Martin Valkyrie, McLaren BP23 and Ferrari LaFerrari Aperta. It is set to go on sale in 2019.

The AMG chief Tobias Moers shared some precious details on the Project One, speaking about powertrain and suspension setup. Mercedes did not leave anything to chance in this ambitious project: it borrowed the technology of the Formula 1 team to give its engineers the right tips to support them in every phase.

The car has a turbocharged 1.6-liter V6 engine. This might seem tiny for this sort of vehicle, but we have to keep in mind that this engine is a close cousin to the one that drove Lewis Hamilton to a F1 championship in 2015, obviously with some opportune modifications and accommodations. The engine of a “classic” Mercedes sports car is sized to offer max power around 6,500 rpm to limit heat, wear and vibrations. In a Formula One car, that value is doubled, reaching around 13,500 rpm. The Project One engine is much closer to the F1 than you may think: it will reach an amazing speed of 11,000 rpm.

The Mercedes engineers also outfitted each front wheel with battery-powered motor good for 161 hp. There is also a third electric motor that supports the turbocharger and an innovative suspension system. 

Mercedes suggests that the main powertrain elements might need to be replaced every 30,000 miles or around every two years.
