The hybrid
propulsion system (V6 1.6 turbo gasoline engine, two
electric engines driving the front axle, another one driving the rear axle — MGU - K, and one more, called MGU - H, virtually driving the turbocharger electrically so no need to rely on excess exhaust gases as until now) from Formula 1
provide a fascinating combination of performance and efficiency.
When cruising at medium to high speeds, the high - efficiency Atkinson - cycle i - VTEC gasoline engine
provides propulsion via a high capacity lock - up clutch, which connects the generator motor (always linked to the engine) and the
electric drive motor, effectively sending motive power directly from the engine to the drive wheels.
In this type mode, the system works as a parallel hybrid in which both the gasoline engine and, when required — for example, upon quick acceleration — the
electric propulsion motor, both
provide power to the wheels.
The
electric propulsion motor alone powers the front wheels, while the gasoline engine (decoupled from the drive wheels) powers the
electric motor / generator motor, which in turn
provides power to charge the 1.3 kilowatt - hour lithium - ion battery pack.
When starting off, the system is in
electric mode in which the
electric motor
provides the
propulsion in first gear.
It leverages drive system components and software from the plug - in Chevrolet Volt to
provide all -
electric propulsion in some driving scenarios, along with power to assist the gas engine.
Apart from the first all -
electric R8,
propulsion is once again likely to be
provided by a naturally aspirated 4.2 - litre V8, albeit with power reportedly ramped up from 316kW to 331kW.
E-power
provides zero - emission
propulsion in front - wheel drive all -
electric mode for up to 19.9 miles.
Engine choices include a normally aspirated V6, a turbocharged V6 in two states of tune, a turbocharged V8, and a plug - in hybrid drivetrain
providing limited
electric - only range before reverting to traditional gas -
electric propulsion.
When cruising at medium to high speeds, the high - efficiency Atkinson - cycle i - VTEC gasoline engine
provides propulsion via a new higher capacity lock - up clutch, which connects the generator motor (always linked to the engine) and the
electric drive motor, effectively sending motive power directly from the engine to the drive wheels.
The
electric propulsion motor alone powers the front wheels, as the gasoline engine (decoupled from the drive wheels) powers the
electric - generator motor, which in turn
provides power to the battery pack.
That's because the Volt also can rely on an
electric propulsion system capable of
providing up to 38 miles of all -
electric travel, matched by a combined efficiency rating of 98 MPGe.
In certain driving situations, the gas engine can also
provide propulsion to the vehicle's front wheels as an assist to the
electric motor.
In this type of operation the system works as a «parallel hybrid» where both the gasoline engine and, when required — for instance upon quick acceleration — the
electric propulsion motor, both
provide power to the wheels.
Detailed energy management for each component, as controlled by the Power Control Unit (PCU), enables this system to make the best use of both the
electric propulsion motor and the gasoline engine to seamlessly
provide smooth and responsive performance and to garner top EPA fuel economy ratings in the midsize hybrid sedan class.
It is thus still working all - electrically, albeit with the engine turning the generator to
provide on - board
electric propulsion energy.
