After a long period of teasing and playing with
shadows, the new Mercedes AMG Project One finally made its world debut as the
world’s first road legal car with a Formula 1 powertrain. Power comes from a
reworked version of the hybrid system found in the W08 F1 car, including the
turbocharged 1.6-liter V6 engine and no less than four electric motors.
The two front electric motors are state-of-the-art
units, being capable of revving up to 50,000 rpm when the current best motors in
the market rev up to 20,000 rpm. The third electric motor is integrated into the
turbocharger while the fourth one is mounted directly on the combustion engine.
Each one of the front motors are producing 160 hp,
with the electric motor on the engine making the same amount of power and the
one mounted on the turbocharger being a 120 hp unit. Total power output
is "over 1000 hp".
Mercedes AMG claims that turbo lag isn’t just
eliminated with this setup but the response times are now even shorter than
those of a naturally aspirated V8. All this was possible not just because of
the torque-fill provided by the electric motors but also thanks to the
electrically-assisted turbocharger which in turn features exhaust gas and
compressor turbines that are separate from each other and mounted at an optimum
position to the exhaust side and the intake side of the V6 unit, and connected
to one another by a shaft powered by the 90kW unit.
Just in case you haven’t realized it yet, this isn’t
your normal boosted hybrid powertrain, this is some next level engineering that
finds its way on public roads for the first time. But what does that mean for
the acceleration figures? Mercedes AMG says that the Project One is capable of
exceeding 350 km/h flat out but we already knew that. What we didn’t
know is that the Project One is capable of a 0-200 km/h in less than
six seconds.
Other things we’ve learned include a 15.5-mile
all-electric range, a drive system that operates with 800 volts instead of the
usual 400, a variable all-wheel drive system with torque vectoring and a
sizeable lithium-ion battery pack that uses the same cells, arrangement and
cell cooling system with -you guessed it- the Mercedes-AMG F1 car. The company
also says that under normal driving conditions, the system recuperates up to 80
percent of the energy needed, which is then fed back to the battery.
Power is transmitted to the rear wheels via an
all-new automated eight-speed manual transmission developed specifically for
the Project One. The gearbox is activated hydraulically and offers both auto
and manual modes, with the latter operated via paddles unsurprisingly. A
high-strength carbon-fiber monocoque body forms the basis for the car, with the
integrated engine and transmission also having load-bearing functions, as both
completely support the rear suspension.
The interior gets a pair of 10-inch high-definition
displays while the steering wheel with the flattened upper and lower sections
hosts the controls for driving modes and suspension setup, the LED shift
display and an airbag. There’s also air-conditioning, power windows and a
rear-view camera, since there’s no back window.
Mercedes AMG will make only 275 examples of the
Project One in left-hand drive only configuration for a price of 2.27 million
each (US$ 2.7 million). All build slots are sold-out at
the moment but don’t expect to see the Project One on the streets anytime soon
as the company has still 18 months of development ahead of delivering the first
production examples.
