One of the Prototype Challenge cars at Kansas Speedway last night. The main Prototypes weren't there, the LMP2's or the DP cars. And this was only the challenge cars that sport 6.2L Chevy engines only and the prototype lights which run turbocharged 4 cyl Mazda engines.

Even though the challenge cars were bigger, louder, more powerful and faster the lights were more fun to watch because of how hard they fought each other for positions.

The Continental Tire championship series was also there and was the main attraction as they had a 2.5 hour race and the prototype cars ran split 45 minute races. One during the day and one at night after the CTC race.
