Mercedes is heavily playing up the Formula 1 roots of the car. From their press release:
“The Mercedes-AMG Project ONE is the first Formula 1 car with MOT approval. Our highly efficient hybrid assembly stems from motor racing and the electrically powered front axle generates a fascinating mixture of performance and efficiency. With a system output of over 1,000 hp and a top speed beyond 217 mph (350 km/h) this hypercar handles exactly as it looks: it takes your breath away,” Ola Källenius says, Member of the Daimler AG Board of Management responsible for Group Research and Mercedes-Benz Cars Development.
The 1.6-liter V6 hybrid gasoline motor with direct injection and electrically assisted single turbocharging comes right from the Mercedes-AMG Petronas Formula 1 racing car. It’s got pneumatic valve springs and can reach an insane 11,000 RPM.
Also, unlike an F1 car, there seems to be a phone caddy in the middle.
