BorgWarner Delivers DualTronic(TM) Transmission Technology and Variable Cam Timing Presentations at SAE World Congress

AUBURN HILLS, Mich., April 11 -- Engineers from leading global powertrain supplier BorgWarner Inc. will present white papers on two of the company's most exciting and high-potential advanced technologies -- BorgWarner DualTronic(TM) transmission technology and variable cam timing -- at the 2005 SAE World Congress, April 11 - 14, 2005 in Detroit.

BorgWarner DualTronic(TM) is the company's wet-clutch and control-system technology for automated transmissions that enables a conventional-looking gearbox to function as a fully automatic transmission, while delivering performance and fuel economy that rivals a manual transmission. DualTronic(TM) eliminates the "torque-interrupt" feeling that occurs when a manual transmission shifts gears, and offers emissions and fuel economy improvements of up to 15 percent over a traditional automatic, depending on the application. DualTronic(TM) debuted on the VW Golf R32 DSG and the Audi TT 3.2 in 2003. It is now available on six other VW/Audi vehicles and will be introduced on several other vehicles during 2005. BorgWarner expects the demand for this technology to grow to 20 percent of the European passenger car market by 2015.

Also featured at SAE this year is a discussion of BorgWarner's technology for variable cam timing (VCT), a development that constitutes a major step in the expansion of BorgWarner's growing engine management business. Variable cam timing is a means of precisely controlling the flow of air into and out of an engine by allowing the camshaft to be dynamically phased relative to its crankshaft. BorgWarner VCT technology includes devices that use camshaft torque as their actuation energy, in contrast to conventional phaser devices that depend on engine oil pressure for actuation. BorgWarner supplies the system that includes the phasing device as well as the variable force solenoid.

The BorgWarner system uses a Torsional Assist(TM) technology that is unique to the industry instead of the conventional oil-pressure actuated approach. It requires fewer engine architecture changes and yields fuel and emissions benefits greater than conventional oil-pressure actuated devices. The new technology is beneficial for both overhead valve and overhead cam engines, and represents a leap to the next generation of cam phasing.

BorgWarner's first VCT systems are being launched on a new family of General Motors V6 engines being introduced this year. Camshaft phasing technology is rapidly becoming a standard in the global engine market. The worldwide market that will use this technology is expected to grow 500 percent from 2000 figures of 5.2 million engines, to over 26 million engines by 2009.

"A Camshaft Torque-Actuated Vane Style (VCT) Phaser" will be presented on Tuesday, April 12th at 10:15 a.m. "Dual-Clutch Transmissions -- Lessons Learned and Future Potential" will be presented that day at 1:30 p.m.
