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.

PRESS RELEASE

Remy International, Inc. Supplying HVH™ Electric Motors to Daimler for 2010 Mercedes-Benz ML450 Hybrid


PENDLETON, Ind., Jan. 20 /PRNewswire/ -- Remy International, Inc. today announced it is supplying Daimler with the Remy HVH™ electric motor used in the 2010 Mercedes-Benz ML450 Hybrid recently released to the United States market.

Remy CEO John Weber said, "Daimler has proven to be a strong partner and we are proud to have our HVH electric motors in the new ML450 Hybrid. Like Remy, the Mercedes brand has represented excellence in quality and design for a century. We look forward to many more years of innovative collaboration with Daimler as we seek to continually improve upon our successful pasts."

The ML450 Hybrid, using Remy HVH electric motor technology, works together with a 3.5-liter V6 engine to attain improved fuel efficiency over comparably powered sports utility vehicles - or when needed, provide the acceleration of a powerful V8. Around town, the ML450 Hybrid can operate as a zero-emission vehicle when powered by its electric drive alone. Using a modified Atkinson cycle for maximum fuel efficiency, the V6 engine kicks in when needed and when accelerating on a freeway entrance ramp for example, the electric drive and combustion engine work together for a total of 335 horsepower.

Remy's advanced motor technology contributes greatly to the Mercedes ML450 Hybrid's performance and efficiency. The ML450 Hybrid will perform like a V8 consuming fuel like a 4-cylinder and can travel as fast as 35 mph while operating in full electric mode. Fuel consumption and emissions are down nearly 60 percent compared to similarly powered vehicles like the ML550.

Remy will be supplying two HVH electric motors per vehicle. The ML450 Hybrid will use the Remy HVH electric motors to provide drive and generation functions. These motors have the highest power and torque density on the market today and are a perfect fit for the ML450 which needed to decrease the transmission size to aid efficiency. The first motor is positioned close to the internal combustion engine and is used both as a motor and generator, providing over 80 hp to assist the drivetrain or charge the vehicle battery. The second motor located at the output end of the transmission generates 80 hp and 192 lb-ft of torque and is tuned for maximum electric drive performance plus recovery of regenerative braking energy to the battery.

The Remy HVH motors for the Mercedes ML450 Hybrid will be manufactured at Remy's manufacturing plant in Mezokovesd, Hungary. And the Mercedes ML450 Hybrid will be produced at the Mercedes manufacturing plant in Tuscaloosa, Alabama.

Remy recently announced the Remy HVH250™ which is an advanced electric motor for hybrid and electric applications based on Remy's patented High Voltage Hairpin (HVH) technology. The HVH technology provides dramatically improved motor performance and cooling effectiveness. The world-class torque and power density allows for increased range in all-electric drive mode and the potential for a smaller internal combustion engine. These factors and more led Daimler to choose Remy's HVH electric motor technology.
