Cadillac equips the 2026 CT5-V Blackwing F1 Collector Series with a supercharged 6.2-liter V8 that produces 685 horsepower. That represents a bump from the standard 668 hp output found in the regular Blackwing. The collector variant bundles this engine upgrade with the Precision Pack as standard equipment, which includes performance chassis tuning and premium braking components.

This move targets collectors and performance purists willing to pay for engineering substance rather than cosmetic tweaks alone. The additional 17 horses demand respect from a sedan that already delivers genuine performance credentials. Cadillac positions this as a limited-run model, capitalizing on the final years of V8 muscle before electrification inevitably dominates the luxury sedan segment.

The F1 designation references the car's connection to Cadillac's racing program. For buyers seeking a traditional high-displacement, naturally-aspirated-plus-forced-induction American luxury sedan, this represents the final chapter. Cadillac builds real performance here rather than chasing horsepower theater. The Precision Pack addition underscores that philosophy, ensuring the extra power translates to measurable improvements in handling and stopping authority.
