TRW Announces Contracts For Vehicle Stability Control Systems For North American and European Platforms

Company Introduces New Product Features and Benefits

May 1, 2002

Building on the success of its advances in vehicle stability control technology, TRW Automotive has announced it will launch its vehicle stability control (VSC) system on four European platforms this year and General Motors full-size sport utility vehicles (SUVs) built in North America. The contract values were not disclosed.

TRW is the supplier for the advanced VSC system on the GM Opel Vectra, launched in January of this year as part of GM's Epsilon platform. This launch was followed by a VSC introduction on the Fiat Lancia Thesis in March. Additional VSC introductions are planned for another GM Epsilon platform vehicle and an unnamed European luxury vehicle this fall. Last year, TRW successfully launched its VSC system for the Fiat Lancia Lybra.

"Launching these European platforms is a significant achievement, illustrates TRW's continuing market share growth, and establishes a significant presence for TRW VSC systems in Europe," said Peter Lake, vice president, Sales and Business Development, TRW Automotive. "It is a testimony to TRW's position as an advanced technology supplier and systems engineering skills."

In North America, TRW is introducing its next generation VSC system on GM full-size SUVs, which include the 2003 Cadillac Escalade, Chevrolet Tahoe, GMC Denali, Chevrolet Suburban, GMC Yukon and Chevrolet Avalanche models. General Motors refers to TRW's VSC systems as Vehicle Stability Enhancement Systems (VSES), under GM's StabiliTrak(TM) name. TRW introduced its first GM application for VSES on the Cadillac Escalade in 2001. TRW will start production of VSC systems for the Ford Windstar minivan within the next year.

TRW's latest generation vehicle stability system provides traction control capability on 4x4 vehicles with open differential drivelines. This industry leading capability provides significant cost benefits to the customer because fewer components are required for the system. The system was designed to provide quieter and smoother performance than previous generations. In addition to standard VSES components, which include an inertial module and electro-hydraulic control unit, TRW also supplies a pre-charge pump and proportioning valve which are especially important for large vehicles, such as the Suburban, to ensure superior system performance at all operating temperatures.

"TRW has brought a best-in-class vehicle stability control system to market and we are proud to work in partnership with General Motors," said Lake. "The success of the Escalade's StabiliTrak(TM) with consumers has proven that TRW provides innovative technology with excellent performance and quality characteristics." TRW developed StabiliTrak(TM) in close collaboration with General Motors, with a large team of TRW engineers working on numerous aspects of the program.

TRW Automotive continues to enhance the functionality of its vehicle stability control systems by including new features in the system, such as "panic brake assist" and "hill hold," which will be introduced on major European platforms this year.

"Panic brake assist" recognizes a panic stop by monitoring the speed and force the driver uses to apply the brakes and augments that braking force to ensure ABS braking in the event of a panic stop situation. TRW has achieved an established leadership position in panic brake assist with its electronically controlled vacuum boosters and is extending its position by incorporating next generation panic brake assist functionality into the VSC system. This VSC-based panic brake assist provides additional functionality by allowing braking modulation throughout the panic stop while increasing the braking force.

The "hill hold" feature uses the vehicle stability system to maintain a driver-generated brake pressure to prevent the vehicle from rolling on a hill in the time between when a driver releases the brake and drives away -- an automatic transmission-style driving feature for manual transmission vehicles.

TRW Automotive is a world leader in braking systems, steering systems, suspension systems, occupant safety systems, electronics, engine valves, fastening systems and aftermarket replacement parts for the global automotive industry. TRW Inc. (NYSE: TRW) provides advanced technology products and services to the automotive, aerospace and information technology markets. The company's 2001 sales were $16.4 billion.
