SRT® Viper GTS-R Unveiled; Set for Return to American Le Mans Series

New two-car SRT Motorsports team plans on-track debut in summer 2012

April 4, 2012 , Auburn Hills, Mich. - The street legal 2013 SRT® Viper unveiled to the world today at the New York
International Auto Show isn’t the only high-performance snake making a triumphant return in 2012.

The purpose-built, non-street legal and competition-ready SRT Viper GTS-R also was revealed as part of the Chrysler
Group’s announcement that a factory-backed SRT Viper Racing team will return to the American Le Mans Series
(ALMS) in 2012.

“Racing has been a significant part of the illustrious history of Viper not only with wins on the track, but also in the
continued development of the street cars – and our new 2013 SRT Viper models are proof of those lessons learned,”
said Ralph Gilles, President and CEO – Street and Racing Technology Brand and Motorsports, Chrysler Group LLC.
“Now with our new team and the launch of the GTS-R, we’re excited and proud to begin writing more chapters in the
racing history of the Viper later this summer.”

SRT Motorsports has partnered with Riley Technologies, based in Mooresville, N.C., on the design-and-build process of
the new SRT Viper GTS-R.

Two identical SRT Viper GTS-Rs will compete in the production-based GT class in the series. Four drivers currently are
signed to drive including Dominik Farnbacher, from Ansbach, Germany; Marc Goossens from Geel, Belgium; Ryan
Hunter-Reay from Dallas and Kuno Wittmer from Montreal. Additional driver and team announcements will be
forthcoming.

Both Viper GTS-Rs will race on the proven Michelin GT tires extending the successful technical partnership.

Scott Atherton, President and CEO of the American Le Mans Series, hails the SRT Viper’s return to the Series as one of
2012’s top announcements.

“I don’t think it’s possible to overstate the significance of the SRT Viper returning to the top level of professional sports
car racing,” Atherton said. “The Chrysler Group has a long, storied and very successful history of competing with the
American Le Mans Series. The fact that they’re coming back concurrently with the introduction of the new production
car and doing it simultaneously, we would be hard-pressed to come up with a better-case scenario. What a great way
for SRT Viper to come back to racing.”

All ALMS teams compete in the prestigious MICHELIN® GREEN X® Challenge. Entering its fourth season, the program
objectively ranks the competing cars in terms of their environmental footprint, their energy efficiency and speed on the
racetrack. A separate, season-long award is given by the U.S. Department of Energy, the U.S. Environmental Protection
Agency and SAE International, acknowledging the vehicle manufacturer and its technology contribution to improving
efficiency and reducing environmental impacts of racing. The scoring system for the program was developed by series
officials and the U.S. Department of Energy, and it is based on a combination of on-track performance and energy
consumption. The LMP and GT teams that win MICHELIN GREEN X Challenge championship will earn an entry to the
2013 24 Hours of Le Mans.

“We often say it’s clean, fast and efficient,” Bob Larsen, president of Obotech and a contractor for the U.S. Department
of Energy, said. “There’s a lot of science that goes into the actual scoring, a very thorough and technically rigorous way
to factor in the environmental footprint. We look at each car’s average speed and the distance that they travel and we
adjust their amount of fuel that they would have had to burn in order to go as fast and as far as the leader, and that
gives us an equitable basis for comparing the performance of the vehicles.”

Viper racing heritage

The Viper has enjoyed a successful racing heritage that began in 1996 with the first Dodge Viper racing entry, the
original GTS-R, which earned five international GT championships and the 1997-1999 FIA GT championships. It also
posted an amazing overall win at the Rolex 24 Hours of Daytona in 2000 – the first for a production-based American car.

Viper finished one-two at the 24 Hours of Le Mans in GTS class in three consecutive years - 1998–2000 - and also
captured GTS class, and driver’s championships in the American Le Mans Series in 1999 along with the Series class,
manufacturer’s and driver’s championships in 2000.

The Dodge Viper Competition Coupe, introduced in 2003, delivered the next chapter of that history with its coupe-
shaped carbon/Kevlar body and a track-ready chassis, based on the Dodge Viper SRT10®. The Viper Competition
Coupe continued the on-track prowess by capturing the 2004 SCCA Speed World Challenge GT title, championships in
Formula D Drifting series in 2004 and 2006 and the British GT Championship in 2007 and 2008.

In 2010, the Dodge Viper Cup Series was founded using the limited-edition Dodge Viper ACR-X spec series cars. Now in
its third year, the series has been renamed the SRT Viper Cup Series.
