For what it's worth, it looks like we're going to run the outer loop rather than the full course at UMC.
I'm assuming demand for rides in the new car will be high. Even on the outer loop, which is 3.05 miles, you're really hauling ass if you're doing a 2:10 lap. Considering an out lap, hot lap, in lap and then the time to get people in and out, there's just no way we'd be able to get people in and out by extending the course even further. Still gets the big straight, and it should be better for all years of the car in hot Utah by getting more air through the car.
I talked to Scott Maxwell (long-time Multimatic driver, FGT race car/road car development driver, CTSC champ) which he preferred, and he told me the 3.05 was more fun in his opinion.
