BorgWarner's Innovative All-Wheel Drive Technology Powers New Porsche Sports Car

BorgWarner friction products, high-flow air pump, lubrication pump and twin turbochargers also provide powertrain benefits

AUBURN HILLS, Mich., Aug. 17 -- BorgWarner's InterActive Torque Management (ITM3e(TM)) all-wheel drive system is standard on the 2006 Porsche sports car that launched this year.

"This application of ITM3e(TM) was by far our most challenging, because of Porsche's legendary vehicle performance targets and a short development timeframe," said Cindy Niekamp, President and General Manager, BorgWarner TorqTransfer Systems. "There were other challenges associated with balancing vehicle traction and dynamics with temperature management."

The all-wheel drive system is compact and lightweight. Its best-in-class low drag torque assures compatibility with brake-based stability control systems and enables fuel economy benefits.

"BorgWarner's electronic control unit (ECU), control algorithms, and precise vehicle tuning, combined with Porsche's standard-setting technology and engineering expertise, equip this vehicle with a combination of racing- level performance and on-road driveability. The result is a truly exceptional driving experience," said Ms. Niekamp.

The Porsche ITM3e(TM) system incorporates technology from other BorgWarner business units as well. The application's torque accuracy and temperature management requirements are achieved through proprietary optimization of BorgWarner Transmissions Systems friction elements and magnetic circuit, combined with BorgWarner electronic controls. To further manage heat energy requirements, the design incorporates a high-speed, low-energy lubrication pump from BorgWarner Morse TEC.

BorgWarner's ITM3e(TM) product family debuted in 2005 on the Hyundai Santa Fe, and will be standard on the 2007 model year Chrysler Pacifica models with AWD.

The Porsche vehicle also includes the first production application of BorgWarner's high-flow air pump, which provides a 30-percent increase in air flow over previous-generation air pumps and plays a significant role in reducing emissions. In addition, it features twin BorgWarner turbochargers, in the first variable turbine geometry application in a gasoline-powered car. The electronically adjustable vanes in the turbocharger provide more torque output to avoid "turbo lag" at lower speeds. Built with high temperature- resistant materials pioneered by the aerospace industry, the system also withstands extreme engine heat. BorgWarner Turbo Systems has been engineering solutions with Porsche for more than 35 years.
