GM RACING'S NEW TWO-STORY ENGINEERING TRAILER RAISES IRL TECHNOLOGY TO
NEW HEIGHTS

INDIANAPOLIS, May 14, 2004 - GM Racing has literally raised the roof with
its new two-story engineering trackside support trailer for the IRL
IndyCar Series. GM's new mobile command center, which expands to a
double-decker "Mission Control" at the touch of a button, is making its
debut at the Indianapolis 500. This state-of-the-art technology center can
accommodate up to 30 trackside support personnel for the Chevy Indy V-8
engine program, yet requires less space and has lower operating costs than
the multiple trailers used by other manufacturers.

On the highway, the GM Racing engineering trailer measures 13-feet,
6-inches tall and 102 inches wide, allowing it to pass easily through
tunnels and beneath bridges. On site at IRL events, a pushbutton hydraulic
system expands the trailer to a height of 17 feet and a width of 150
inches, providing 1,000 square feet of interior space. The trailer is
equipped with a satellite dish for high-speed data transmission, a weather
station, a vehicle simulator, a local area network and a radio
communications center.

"GM Racing's engineering support for Chevrolet's IRL engine program
has expanded dramatically in 2004 with new services for teams using Chevy
Indy V-8 engines," said GM Powertrain IRL program manager Dennis Weglarz.
"There was a real need for more workspace, but we wanted to come up with a
more innovative solution that simply parking more trailers in the already
crowded pits. The new two-story trackside support center achieves this goal
efficiently and effectively."

The ground floor of the trailer contains workstations for 15 trackside
support personnel, all linked through a local area network. There is
storage for four Chevy Indy V-8 engines, tool cabinets, workbenches, a
kitchen and a restroom. A staircase at the front of the trailer leads to
the GM Racing Communications trackside office and a second workroom on the
upper level with six workstations and a 12-seat conference room. Fully
enclosed with glass windows, the upper level provides a panoramic view of
the track. A satellite dish, weather station and UHF radio antenna are
mounted on the roof.

"While some people might think that a two-story trailer is a luxury,
the project was really driven by efficiency," said Weglarz. "The expanding
trailer is actually less expensive than two comparable conventional
trailers. It requires only one truck and one driver, so the over-the-road
costs are reduced. At GM Racing, we strive to spend every dollar wisely. We
decided that we could best serve the Chevy teams, who are our customers at
the track, if we had a single trailer that was large enough to house our
entire trackside engineering support staff in one location.

"We have technical partners around the world working together on the
Chevy Indy V-8 engine program," Weglarz noted. "Through the satellite dish
we have a high-speed data link with Detroit, England and Europe. Using the
onboard weather station and a system of pagers, all of the Chevy teams,
engineers and trackside technicians have access to the same accurate
weather information in real time. That's important not only for the
calibration of the engines, but also for tuning the aerodynamics of the
race cars. The trailer also has a radio repeater that ensures dependable
communications throughout the track."

GM Racing's engineering focus at the race track is on electronics
and software. The trailer is outfitted with a vehicle simulator that allows
GM Racing engineers to develop new algorithms and test calibrations for the
Chevy Indy V-8's electronic engine management system before putting them in
a race car.

"The best people need the best tools," Weglarz noted. "The GM
Racing engineering trailer is a cutting-edge tool that demonstrates our
commitment to provide exceptional engineering support for teams using the
Chevy Indy V-8 engine."
