"... The heart of the system is a six piston radial digital displacement hydraulic pump/motor. This hydraulic motor replaces the port plates and swash plates in conventional hydraulic machines with computer controlled high-speed solenoid valves. Driven by a microprocessor, these solenoids actively control poppet valves that rectify the flow into and out of each cylinder. The hydraulic pump attaches to the flywheel an conventional combustion motor replacing the gearbox. It is hydraulically connected to Digital Displacement Motors coupled to the wheels, so the only connection between the internal combustion motor and the wheels is the hydraulic system.

In operation the system is conceptually similar to an electric series hybrid but with a pressure accumulator taking the place of the battery. The combustion engine generates hydraulic pressure at a steady rpm that can either drive the wheels with the hydraulic motor coupled to the wheels, or be added to the accumulator for later use. When the vehicle slows down the wheel coupled motor turns into a pump and regenerates braking energy into hydraulic pressure that is stored in the accumulator..."

Neat! But that would be really weird to drive, since the correlation between motor output and power to the wheels is lessened.

So the american government is giving billions of dollars to the car companies to figure out some new technology to improve gas milliage or create a better solution, and BMW figured it out without any extra cash? WTF?

BMW is freaking awesome!
