Cadillac Challenge Takes To The Circuit Of The Americas: Video - GM Authority (blog)
The Cadillac Challenge, the first and only race series exclusively for Cadillac vehicles, recently took to the Circuit of the Americas in Austin, TX, for Round 4 and 5 of the ten round series. Stock vehicles join the Cadillac Racing C1 class while tuned vehicles get lumped into the Borla Exhaust C2 category. Meanwhile, all the “unlimited” Cadillacs – the most extreme class – get thrown into the D3 Cadillac C3 class. The next round of the Cadillac Challenge will take place at Spring Mountain on May 16-17. Until then, you can get caught up on the first three rounds right here. Source: gmauthority.com
