Delphi's New Gasoline Direct Injection (GDi) System Lowers Emissions and Ignites Performance

Affordable, Quiet, Flexible System Improves Power and Performance While Reducing CO2 and Regulated Emissions

FRANKFURT, GERMANY--(Marketwire - September 7, 2007) - Delphi (PINKSHEETS: DPHIQ) is launching a new, high-performance Gasoline Direct Injection (GDi) system that is optimised for the increasing use of turbochargers and bio-fuels as a flexible, cost-effective solution to global pressures on emissions and CO2 emissions. Supported by its global network of powertrain technical centers, Delphi is poised to supply the total system -- including injectors, pumps, engine control units, electrical/electronic systems, fuel rails and fuel handling hardware -- or individual components.

The heart of Delphi's homogeneous GDi system -- named Multec 10® -- is a new multi-hole injector, designed for homogeneous lambda=1 combustion and available with spray preparation options optimised for a wide variety of combustion chamber shapes and static flow requirements. Highly refined solenoid technology allows very fast opening and closing, which enables the Delphi system to provide a linear range of more than 15 (the relationship between maximum fuel flow and minimum fuel flow), substantially higher than today's best production systems.

"Delphi's GDi system takes into account two key trends that we see in the requirement for gas injection systems," explains Mark Shost, Delphi Engineering Director for Engine Management Systems and Products. "First, there will be rapid growth in turbocharging as engines are downsized to reduce CO2 emissions. Second, we see bio-fuel content of gasoline increasing, particularly in the United States and Europe."

Delphi injectors' high linear range make the system ideal for turbocharged applications, where significantly higher fuel rates on a full load are required without compromising fuel rate control at idle. Innovative engineering delivers zero pintle bounce when closing, with very low noise, making it the quietest injector on the market. Careful optimisation of the magnetic and hydraulic characteristics allows extremely high performance economically.

After tapping into extensive experience with bio-fuels in the South American market, Delphi achieved bio-fuel optimisation by carefully selecting and testing materials and coatings to ensure they will withstand high bio-fuel contents -- like ethanol. For example, high-pressure fuel rails are manufactured from stainless steel with brazed caps instead of today's popular aluminium rails which may suffer from internal corrosion if run for long periods on bio-fuels. To increase durability, fuel-contacted parts inside the all-new high-flow fuel pump are constructed from stainless steel. The same pump can be adapted for all sizes of four- and six-cylinder application, providing component cost savings, part number reduction and simplified manufacturing. The pump delivers up to 150 bar pressure for homogenous charge applications and up to 200 bar for next-generation stratified charge applications.

Delphi's new GDi system is targeted to meet today's most demanding emissions requirements -- including SULEV and EURO 6 -- without the cost of a complex after-treatment system. After engine start, multiple injection pulses enable accelerated catalyst heating reducing unburned hydrocarbons, thereby allowing further cost savings by reducing catalyst precious metal content.

Coupled with Delphi's components is a comprehensive library of Engine Management Systems (EMS) control algorithms. This set of "state-of-the-art" algorithms uses a torque-based strategy that seamlessly aligns the driver's command to the powertrain output, thus simplifying the application of the Delphi system to various vehicles over a wide array of regional and customer driven requirements. Delphi continues to lead the industry in cost and flexibility through the use of innovative control algorithm solutions.

Multec GDi is ready for applications engineering today, with production expected early 2010. Delphi predicts that about 40 percent of new European gasoline vehicles will be fitted with direct gas systems by 2010.

Delphi is also developing a GDi system for stratified charge (lean) combustion engines named Multec 20®. These systems require very low sulphur fuel to protect lean-burn-compatible catalytic converters, but offer a further fuel economy saving of around 15 percent. Delphi actuates its outward opening injector for stratified charge systems by a single coil, which offers a significant cost advantage over competitors' piezoelectric injectors. With the same external diameter as the homogenous charge GDi injector, systems can be fitted to engines with centrally mounted injectors with minimal, if any, revisions to the cylinder head. Due to the injector's solenoid actuation, the system can use the standard GDi ECU, bringing further simplification and cost savings.

To further increase the operating range and improve fuel economy on stratified GDi engines, Delphi has employed its Multi-Charge Ignition System. Multi-Charge features a coil-per-cylinder control system that enables

--  longer spark duration,
--  increased spark energy, and
--  re-ignition in the event of combustion blow-out when liquid is
    present.
    

Firing multiple times in a short timeframe, Multi-Charge Ignition ensures initiation of robust combustion and compensation of fuel spray variation.

"We now have a complete range of diesel and gasoline injection systems that includes MPFI, GDi, Common Rail diesel and heavy duty diesel," says Shost. "With our stratified charge GDi system and a technology pipeline ready for HCCI -- including enabling technologies like advanced variable and two-step valve train -- and other advanced combustion technologies, Delphi can support engine design strategies well into the future."

FORWARD-LOOKING STATEMENT

This press release, as well as other statements made by Delphi may contain forward-looking statements that reflect, when made, the Company's current views with respect to current events and financial performance. Such forward-looking statements are and will be, as the case may be, subject to many risks, uncertainties and factors relating to the Company's operations and business environment which may cause the actual results of the Company to be materially different from any future results, express or implied, by such forward-looking statements. In some cases, you can identify these statements by forward-looking words such as "may," "might," "will," "should," "expects," "plans," "anticipates," "believes," "estimates," "predicts," "potential" or "continue," the negative of these terms and other comparable terminology. Factors that could cause actual results to differ materially from these forward-looking statements include, but are not limited to, the following: the ability of the Company to continue as a going concern; the ability of the Company to operate pursuant to the terms of the debtor-in-possession financing facility; the terms of any reorganization plan ultimately confirmed; the Company's ability to obtain Court approval with respect to motions in the chapter 11 cases prosecuted by it from time to time; the ability of the Company to develop, prosecute, confirm and consummate one or more plans of reorganization with respect to the chapter 11 cases; the Company's ability to satisfy the terms and conditions of the Equity Purchase and Commitment Agreement (including the Company's ability to achieve consensual agreements with GM and its U.S. labor unions on a timely basis that are acceptable to the Plan Investors in their sole discretion); the Company's ability to satisfy the terms and conditions of the Plan Framework Support Agreement; risks associated with third parties seeking and obtaining Court approval to terminate or shorten the exclusivity period for the Company to propose and confirm one or more plans of reorganization, for the appointment of a chapter 11 trustee or to convert the cases to chapter 7 cases; the ability of the Company to obtain and maintain normal terms with vendors and service providers; the Company's ability to maintain contracts that are critical to its operations; the potential adverse impact of the chapter 11 cases on the Company's liquidity or results of operations; the ability of the Company to fund and execute its business plan (including the transformation plan described in Item 1. Business "Potential Divestitures, Consolidations and Wind-Downs" of the Annual Report on Form 10-K for the year ended December 31, 2006 filed with the SEC) and to do so in a timely manner; the ability of the Company to attract, motivate and/or retain key executives and associates; the ability of the Company to avoid or continue to operate during a strike, or partial work stoppage or slow down by any of its unionized employees and the ability of the Company to attract and retain customers.

Similarly, these and other factors, including the terms of any reorganization plan ultimately confirmed, can affect the value of the Company's various prepetition liabilities, common stock and/or other equity securities. Additionally, no assurance can be given as to what values, if any, will be ascribed in the bankruptcy cases to each of these constituencies. A plan of reorganization could result in holders of Delphi's common stock receiving no distribution on account of their interest and cancellation of their interests. In addition, under certain conditions specified in the Bankruptcy Code, a plan of reorganization may be confirmed notwithstanding its rejection by an impaired class of creditors or equity holders and notwithstanding the fact that equity holders do not receive or retain property on account of their equity interests under the plan. In light of the foregoing, the Company considers the value of the common stock to be highly speculative and cautions equity holders that the stock may ultimately be determined to have no value. Accordingly, the Company urges that appropriate caution be exercised with respect to existing and future investments in Delphi's common stock or other equity interests or any claims relating to prepetition liabilities.
