US: BorgWarner claims dual-clutch advances

By just-auto.com editorial team | 12 November 2007

BorgWarner says it is introducing new, high efficiency shifting technology as it partners with customers to develop next generation dual-clutch transmissions. 

BorgWarner claims that innovations in advanced materials and control systems have led to fuel efficiency that is projected to be 40% greater than the improvement delivered by the already fuel-efficient dual-clutch transmissions in production today.

"As a pioneer in dual-clutch technology we are always working to improve shifting efficiency and provide the best value to our customers," said Dr. Bernd Matthes, President and General Manager, BorgWarner Transmission Systems.

"Given the traditional lengthy process for new transmission developments, our market-leading expertise in dual-clutch transmissions and clutch and controls technology helps us shorten the development cycle in line with customer and market needs."

BorgWarner says breakthroughs in advanced friction materials, heat exchange improvements and optimised control systems enable a dual-clutch design that uses less lubrication and a smaller pump.  This "humid" or moist-clutch operating environment fosters greater fuel efficiency than the current wet- clutch configuration.  Today's dual-clutch transmissions on average deliver a 5% or more improvement in fuel economy over current six-speed transmissions. Now, BorgWarner's next generation dual-clutch technology provides enhanced materials and controls that boost the efficiency by an additional 2%, the firm claims.

The company expects to quadruple its dual-clutch module production over the next six years.  At full-launch of announced programs, BorgWarner expects to be providing its innovative DualTronic technology to an expected 2.3 million dual-clutch transmissions per year.  The company says it has been awarded business from transmission and vehicle makers around the world, including programs with VW, Audi, Bugatti, SAIC, Nissan, and Getrag programs with five global automakers.

Global manufacturing capacity for BorgWarner dual-clutch transmission modules is supported by its facilities in the United States, Germany, France and China, and a new facility in Mexico.
