GM Racing Q&A on Chevy Indy V8

PHOENIX - Chevrolet's 2003 Chevy Indy V8 racing engine, which was designed
and developed in-house by GM Racing, debuted at the season-opening event of
the 16-race Indy Racing League IndyCar Series in Homestead, Fla., on March
2. In the following Q&A, Joe Negri, GM Racing Group manager, and Steve
Shannon, GM executive director - marketing services, discuss the progress
of Chevrolet's IRL program going into the second round of the IndyCar
Series, the Purex/Dial Indy 200 at Phoenix International Raceway on March
23.

Q. What is the current status of Chevy's IndyCar Series program?

Joe Negri: We are aggressively pursuing research and development programs
with the new Chevy Indy V8, and we have made improvements for Phoenix. In
addition to our engine development program, we have been working very hard
with Chevrolet teams on chassis and aerodynamics because we recognize that
it takes a complete package to be competitive on the race track.

Q. What are the areas that GM Racing is focusing on?

Negri: We are concentrating on areas that will increase horsepower and
improve fuel economy. These include optimization of the camshaft timing,
compression ratio, and intake and system tuning. Experience teaches us that
at the beginning of a season with an all-new engine design, reliability is
paramount. There were no failures in the opening race at Homestead with the
new engines, which was a remarkable achievement by all three of the
manufacturers in the IRL.

Our top priority was to bring a reliable engine package to Homestead, and
we achieved that goal. Now that we have proven the soundness of the basic
engine design, we are shifting our focus to developing more power and
enhancing fuel economy.

Q. Were there any issues with the new 2003 chassis?

Negri: Most of our preseason testing was done with modified 2002 chassis.
When teams tested the 2003 chassis at the Test in the West, we found that
the new chassis were not as well suited to our engine as the previous
version. The teams and chassis manufacturer responded quickly to make
changes before the Homestead race and those problems are now resolved.

Q. What are your expectations for the Phoenix race and beyond?

Negri: Like Homestead, the Phoenix track emphasizes handling as well
as horsepower. Chevy teams have tested well at Phoenix and have made
significant strides in understanding the setups for their new chassis. We
are making continuous improvements in engine performance as well and we
expect that they will become apparent as the season continues.

Q. Are you planning to add any teams to the Chevrolet roster?

Negri: At this point we do not intend to add any more development teams,
and we are working hard to help our one-car teams grow to two-car teams.
While the current economic climate has made sponsorship a difficult issue
in all forms of motorsports, we have programs in place to assist Chevrolet
teams in securing the funding they need. We are optimistic that these
efforts will ultimately prove successful.

Q. Has GM sought any concessions from the IRL?

Negri: Absolutely not. We have never discussed concessions, and we do
not expect or want the IRL to make concessions for any manufacturer.

Q. Will GM Racing submit new "closed" engine components to the IRL
for approval?

Negri: That is the system that has been in place during the six years that
GM has competed in the IRL. In the past, when GM or Infiniti developed new
major engine components, they were submitted to IRL technical officials
for approval. In some instances, they were approved immediately, and in
others we had to wait for approval. For example, we introduced new cylinder
heads for the IRL Aurora V8 in August 2000. GM Racing subsequently made
changes in the block which we also submitted for approval.

We are committed to continuously improving the Chevy Indy V8, and when
we develop new major components we will submit them for IRL approval as we
have done in the past.

Q. Can GM compete with the new manufacturers in the IRL?

Steve Shannon: The fact is that we compete successfully with them every day
in the marketplace for car and truck sales. GM is the No. 1
automobile manufacturer in the world, and we very familiar with global
competition. Competition is what drives us to improve quality and value for
our customers.

GM competes with a wide range of manufacturers on the race track, from
our domestic rivals in stock car racing to exotic marques in international
road racing. Chevy has won more championships in major motorsports series
than any other manufacturer, and Chevy engines dominate grassroots auto
racing. Today Chevrolet is the only manufacturer that races in the Daytona
500, the Indianapolis 500 and the 24 Hours of Le Mans. So when you look at
the big picture, the IndyCar Series is one of many series in which
Chevrolet participates as part of its overall business plan.

Q. What is GM's commitment to the IRL?

Shannon: GM is committed to be an engine supplier and marketing partner
with the IRL through at least 2005. This is the continuation of a
relationship that began in 1996, so we have made a long-term commitment to
the success of the series.
Motorsports is cyclical, and we recognize that you can't win every
race. Students of racing history know GM's current rivals in the IRL have
struggled at times in the past in open-wheel racing, just as Chevrolet
initially struggled in the mid-'80s. The first-generation Chevy Indy V8 was
winless in 1986, but just two years later Chevrolet won 14 out of 15 races.
To put the current situation in perspective, we've had one race in the
first season of a three-year commitment we've made to the IRL. Chevy is in
racing for the long run, and that is what has made Chevy the most
successful manufacturer in American motorsports.
