It also, though, has an electric motor that provides additional power to the rear wheels (through the same gearbox) and a second electric motor connected directly to the front axle.
ECONOMIST: Fast cars will go even faster with electric power
In addition to the petrol engine and electric motor, the LF-CC hybrid drive system further comprises a generator, a high-performance battery, a power split device which, via planetary reduction gears, combines and re-allocates power from the engine, electric motor and generator according to operational requirements, and a compact power control unit to govern the high speed interaction of the system components.

PowerBox Concept hybrid, for example, shown at the L.A. show, looks a lot like a standard sports utility vehicle (SUV) but combines a supercharged V-6 engine that runs on compressed natural gas and an electric motor that provides added power for acceleration and passing.
In the latter scenarios, the regenerative drive generates electric power as the motor rotates backwards.

The electric motor is used for propulsive power as often as possible in this situation.

The hybrid recaptures energy through a process known as regenerative braking -- where the energy normally lost through braking or coasting goes to power the electric motor.
It runs on battery power for about 40 miles, after which a small gasoline engine kicks in to power an electric motor that extends the EV range for up to 300 miles.

In this case, however, the front electric motor-which is now supplied with energy by the TDI engine-operates exclusively as a generator and a power source for the electric motor at the rear.

The electric drive produces 95 hp, more than double the power of the previous model's electric motor (47 hp).

Essentially leveraged as a form of high-tech turbocharging, here a small electric motor gives a modest fuel-free power boost to a direct-fuel-injected 2.4-liter four-cylinder engine.
For an example, in a hybrid car, a radiator works to cool the combustion engine while a second radiator cools the power electronic system that runs the electric motor.

Members included Ford Motor, Amtrak, DuPont, Dow Corning, American Electric Power, International Paper and Waste Management, along with the states of Illinois and New Mexico, seven cities and a number of universities.
The 2.5-liter inline 4-cylinder gas engine and permanent magnet AC synchronous electric motor in the MKZ deliver 191 net horsepower, a modest amount of power for a 3, 752 lb vehicle.
The system delivers about 165 watts of power per hour to an added battery, which helps powers the electric motor, Johanson said.
Because peak power arrives at different rpm for the gas engine and the electric traction motor, peak system horsepower nets out to be an even 200 hp at 5, 600 rpm, which is the rated redline.

The first patent for strapping an electric motor onto a bike was filed with the US Patent office in 1890 but, lacking sufficient battery power, these early bikes had a very limited range.
