Cadillac's 2026 CT5-V Blackwing F1 Collector Series pushes the supercharged sedan into legitimate performance territory. The engine receives an upgraded supercharger that lifts output to 685 horsepower, a meaningful jump from the standard Blackwing's 668 hp. That extra 17 horses matter less than the refinement and reliability gains the upgraded compressor delivers.
The package arrives standard with Cadillac's Precision Pack, which bundles performance essentials. Buyers get Magnetic Ride Control suspension tuning, upgraded cooling systems, and enhanced braking hardware. The combination targets drivers who want their luxury sedans to actually perform at track-day intensity.
Cadillac positions this variant as a collector's car. The F1 branding references Formula 1 engineering influence, though the connection remains largely aesthetic. Still, the horsepower bump and suspension package distinguish it from lesser Blackwing trim levels. At this power level, the CT5-V Blackwing seats itself alongside AMG E63 and M550i territory, though with less prestige and slightly lower price points.
The 6.2-liter twin-turbocharged V8 (enhanced by that upgraded supercharger arrangement) sends power through an 10-speed automatic transmission to a limited-slip differential. Zero to 60 mph happens in roughly 3.5 seconds. Top speed hits 190 mph, assuming you find appropriate space.
For context, GM's high-performance sedan strategy has narrowed considerably. The Cadillac Blackwing line represents one of the few remaining naturally aspirated or forced-induction V8 sedans available in America. Dodge killed the Charger R/T. BMW's M550i exists, but M5 buyers typically step up.
