Power, Where you Least Expect It

Vonnen Shadow Drive Electric Motor/GeneratorTucked between the engine and the transaxle, the liquid-cooled Vonnen Shadow Drive™ motor delivers a serious punch of additional torque from idle through redline.
The patent pending technology in Shadow Drive allows a slim-profile electric motor to take the place of the factory flywheel.

150hp (110kW) Fits in a Pizza Box?

Vonnen’s compact electric motor adds more horsepower than a 1973 Porsche 911 engine and recharges it’s own battery pack on the fly

A Featherweight with a Powerful Punch

Optimized for rapid bursts of power instead of maximizing driving range, Shadow Drive’s battery is a lot lighter and more compact than those found in traditional EVs. As a result, the entire system weighs in at a mere 170lbs (77kg) net – about the same as a passenger or a tank of fuel.

Power Management

Shadow Drive’s inverter converts DC power from the batteries to AC power for the motor for acceleration and AC power back to DC power to recharge the batteries when the engine has surplus power, for example, during deacceleration or via regenerative braking.

Keeping it Cool

Like your car’s engine, Vonnen’s electric motor and battery pack are liquid-cooled. This helps keep them in the ideal temperature range regardless of the ambient outdoor temperature

Seriously Smart, and Seriously Rewarding Too

There’s something immensely satisfying about watching the power meter sweep in real time. Shadow Drive’s Bluetooth® app allows you to select various drive modes through your smartphone or to disable it entirely
