Cadillac is giving its already formidable CT5-V Blackwing an extra dose of performance as the luxury brand prepares for its upcoming Formula 1 debut, unveiling a new ultra-limited F1 Collector Series that quietly raises the bar for the super sedan.Check out these cars for sale:1983 Buick Electra Park Avenue1951 Pontiac Chieftain Custom Street RodPierce Arrow MotoretteCadillac DevilleThe special-edition CT5-V Blackwing becomes the most powerful version of the car yet, now producing 685 horsepower and 673 lb-ft of torque from its supercharged 6.2-liter LT4 V8. The increase may appear modest on paper compared to the standard Blackwing’s 668 horsepower output, but Cadillac’s engineering changes go beyond a simple power bump.AdvertisementAdvertisementDeveloped with input from GM Motorsports, the upgrades focus heavily on improving airflow, cooling efficiency, and consistency during demanding driving conditions, particularly on track. The revised setup centers around the Eaton TVS R1740 supercharger, which already plays a major role in the Blackwing’s aggressive performance characteristics.Cadillac engineers fitted the engine with a smaller supercharger pulley, increasing the drive ratio from 3.14 to 3.24. The adjustment allows the supercharger rotors to spin faster, generating additional airflow and higher boost pressure for the V8.The company also redesigned the supercharger lid with a taller CNC-machined billet cover that increases internal air volume. The revised housing is intended to help reduce charge-air temperatures during repeated hard laps or prolonged aggressive driving, an important factor for maintaining reliable performance in supercharged engines where heat buildup can quickly reduce efficiency.Rather than focusing solely on headline numbers, Cadillac appears to have prioritized sustained performance and drivability under demanding conditions, giving the F1 Collector Series a more serious track-oriented edge than the standard CT5-V Blackwing.AdvertisementAdvertisementVisually, the limited-production sedan adopts a darker and more understated appearance. The car features Midnight Stone Frost paint, carbon flash wheels, and gloss black exterior accents. Cadillac also incorporated Formula 1 and FIA-inspired branding throughout the vehicle, though the design details remain intentionally subtle.Production will be extremely limited, with just 26 examples planned worldwide. The number was chosen to coincide with Cadillac’s first Formula 1 season while also marking the closing years of the current Blackwing generation.Cadillac has not yet released official pricing for the F1 Collector Series, though the combination of increased performance, motorsports engineering, exclusivity, and Formula 1 branding is expected to place it well above the standard CT5-V Blackwing in cost.The result is a sedan that keeps the core ingredients enthusiasts value most — rear-wheel drive, a supercharged V8, and a six-speed manual transmission — while adding a sharper motorsports connection and even more capability beneath the surface.⚡️ Read the full article on MotoriousSign up for the Motorious Newsletter.
