Pikes Peak International Raceway (PPIR). Indy Racing League (IRL). These pictures were taken during the second IRL race at PPIR in 1999.
The cockpit is all high-tech. LCD displays for all functions.
All IRL cars use this super-modified Oldsmobile Aurora engine.
 
 
You can get a good look at the cars in the pits.
This dude is ready for racing.
