The Circuit of the Americas held its first series of night races during the 2014 WEC Lone Star LeMans. This brought on a new challenge to the track regulars, like Hooniverse-favorite Jeff Mosing, and to the giants of WEC. This was in part due to the fact that COTA is not a night circuit — lighting is provided by rented light towers placed along the track in select areas.
This means much of the course is lit solely by the lighting signatures of the cars racing it. It turns into a dark carnival at times. A pack of raucous GT and LMP cars break the crest of the kilometer-long straight at 170 miles per hour, their bombastic engine notes harmonizing on the back-half of the slope as they prepare to ignite their brake rotors for the 30 mile per hour 90-degree left at the end.
