Cadillac is celebrating its new Formula 1 team with a very limited run of CT5-V Blackwing sedans. The CT5-V Blackwing F1 Collectors Series features an upgraded supercharger, which raises the engine's output to 685 horsepower and 673 pound-feet of torque. In addition to the extra power, the F1 Collectors Series wears a murdered-out appearance meant to celebrate the Cadillac F1 team's livery.
