XM WEATHER TECHNOLOGY DRIVES ANDRETTI GREEN RACE DAY STRATEGY

Indianapolis, IN, May 27, 2007 - The latest race technology was engineered for wings, not wheels, but it is now a unique new addition to Andretti Green Racing's arsenal of strategic tools. While other teams rely on local weather forecasts, AGR through its partnership with XM Satellite Radio has exclusive access to real-time weather data, delivered trackside to team computers by XM's powerful satellites. The result is up-to-the-second intelligence about critical weather elements that can impact race car performance, from wind speed and humidity to storm cells and lightning strikes.

While other teams rely on local weather forecasts to formulate their strategy, AGR engineers receive a constant stream of localized weather data directly to pit computers. The data is overlaid on a GPS map, and can be viewed in multiple formats. The result is an extensive system of current and approaching weather measurements, all of which allow AGR to customize racecar set-up and formulate strategy.

For example, accurate humidity and air density measurements are critical in optimizing car set-up as they can impact downforce, overall engine performance, even gear ratios. And, a weather condition such as cloud cover has a direct impact on track surface temperature, which in turn is a consideration when planning tire strategy.

"With weather forecast to be a major factor in this year's Indy 500, we're happy to have XM Weather technology available as an additional strategic tool," said Kim Green, co-owner, Andretti Green Racing. "Racing is both science and art, and successful racing requires the absolute best combination of both."
