Yahoo Autos Mercedes-AMG One finally here with 1,049 hp of awesome
Dieter Zetsche and Lewis Hamilton presided over the debut of what was then called the Mercedes-AMG Project One at the 2017 Frankfurt Motor Show. Back then, "the hottest and coolest car" Mercedes-AMG had ever attempted was going to be released in 2019. Then the 11,000-rpm, 1.6-liter V6 engine and its dislike for low-speed urban driving met increasingly strict emissions regulations, and it took the carmaker's engineering might five years to overcome that hurdle and others. Five years on, the delay provided AMG the chance to launch what is now the Mercedes-AMG One on the 55th anniversary of AMG's first building, the foundation stone for which was laid on June 1, 1967.
Not since the McLaren F1 have we seen a road car work so hard to adhere to Formula 1 principles, and in fact, the AMG One (and the Aston Martin Valkyrie) go further. Much has changed since the show car — Zetsche and Moers are no longer Mercedes execs, for instance — but not the vital hardpoints. The root is the E Performance powertrain, which is that 1.6-liter V6 boosted by two turbochargers. The 121-hp MGU-H turbo works off exhaust gasses but gets help spinning up to speed with an electric motor. The 161-hp MGU-K turbo is connected to the crankshaft via a spur gear. There's 1,049 system horsepower. AMG declined to peg a torque figure, saying, "Specification not possible due to complex drive train." AMG also declined to list an actual rev limit; the engine's been designed to spin to 11,000 rpm, but the engineers decided "for longer durability and use of commercial super plus petrol, [the engine] deliberately stays below the F1 rev limit." Engine output is marked as 566 horsepower at 9,000 rpm, so owners won't be walled off far away from the physical limits.
Output runs through a new seven-speed manual transmission with shift rods and four carbon clutches instead of the eight-speed manual in the Frankfurt show car. The fully locking differential is integrated into the gearbox.
Two more motors each contribute 161 hp to drive the front wheels, providing fully-variable all-wheel drive and torque vectoring. They also provide the car a pure-electric range of 11.2 miles thanks to an 8.4-kWh liquid-cooled lithium battery that mimics the unit from the Mercedes-AMG Petronas Formula 1 car, but with more cells. This being a PHEV, the charge port is on the rear left of the car, opposite the fuel filler cap for the 14.5-gallon tank.
Getting access to the ICE power means pressing the red start button between the front seats. That activates the electric motors immediately. The driver must then wait for the exhaust aftertreatment subsystem to reach operating temperature. The subsystem consists of four metal catalytic converters, two ceramic catalytic converters, and two gasoline particulate filters, and it was the circuit that pushed engineers to their limits.
