Daimler is now building its own version of the two-mode hybrid transmissions that were co-developed with General Motors and BMW. The Daimler-built transmissions are used in the Mercedes-Benz ML450 and BMW X6 hybrids. Inside of each of those transmissions are two electric motor/generators which are produced by former GM parts division Remy International.

The motors are based on Remy's high-voltage-hybrid (HVH) technology, which provides increased power and torque density with better cooling efficiency. Daimler wanted to build a more compact version of the two-mode transmission than the one used by GM, so a more efficient motor was required. Each transmission contains tow motors, both of which can provide electric drive. The forward-mounted motor also provides engine-driven electric generation to charge the battery and power vehicle systems. The rear motor provides regenerative braking.

The motors are built at a Remy plant in Hungary and assembled into the transmissions in Germany. Both the X6 and ML hybrids are built in the U.S., in South Carolina and Alabama respectively.
