Delphi's Direct Acting Common Rail Injection System -- Now on Mercedes-Benz E-Class Sedan and Coupe -- Showcased at Event; Delphi Presenting Paper on Breakthrough Direct Acting Common Rail System Improvements in Emissions, Power and Fuel Economy

VIENNA, AUSTRIA -- (Marketwire) -- 05/06/09 -- Discussions at the 2009 Vienna Motor Symposium are sure to center upon how automakers and suppliers are striving to meet stringent emissions standards while improving fuel economy and performance. During the show, Delphi Corporation (PINKSHEETS: DPHIQ) will showcase a variety of solutions to those issues with a product line-up that includes a full range of gasoline and diesel engine management systems, modules and components as well as a line-up of fuel handling solutions.

In addition, Delphi is announcing that its revolutionary Direct Acting diesel fuel injection system is being used more widely by Mercedes-Benz vehicles, and Delphi executives will present a paper at the symposium providing a technical description of the premium system's design, working principles and performance characteristics. The results presented in the paper show that the new Direct Acting common rail system is designed to meet the needs of future diesel powertrains that are being designed for high boost, high power density, and low emissions using advanced injections strategies and low fuel consumption -- potentially in conjunction with other technologies.

MERCEDES-BENZ E-CLASS LINE-UP FEATURES OUTSTANDING FUEL ECONOMY, REDUCED EMISSIONS AND IMPROVED ENGINE POWER AND TORQUE

Delphi unveiled the next generation of diesel fuel injectors -- named the Delphi Direct Acting common rail system -- in Sept. 2008. Last December, Delphi announced that the new system would debut on the Mercedes C250 CDI.

Since the beginning of this year, Daimler has introduced two new models fitted with Delphi's system: the new E-Class sedan unveiled at the North American International Auto Show in January and the new E-Class coupé which debuted at the Geneva Motor Show in March.

The new E-Class line-up takes advantage of Delphi's revolutionary technology to offer drivers improved engine output and torque while reducing emissions and fuel consumption. The new E-Class sedan is available with completely new four-cylinder engines in two versions equipped with Delphi's Direct Acting common rail injection system:

--  The E250 CDI with 150 kW/204 hp and 500 Newton meters develops a 25
    percent higher torque than the previous V6 diesel engine but uses around 23
    percent less fuel at only 5.3 liters per 100 kilometers (combined NEDC
    consumption).
