The production version of the Mercedes-AMG One hypercar, which took five years to develop, uses a Formula 1 inspired hybrid drivetrain to produce 1,049 hp (1,063 PS) from a 1.6-liter gasoline engine paired with four electric motors.
The One was first shown as a concept called the Project One at the 2017 Frankfurt auto show, and since then Mercedes has reportedly sold all 275 units planned for production at a price of $2.7 million.
Mercedes said it faced daunting technical challenges to bring the mid-engine, all-wheel-drive One to production, and hinted that the project was not certain to be completed.
