The Blackwing name has been slapping since Cadillac first bolted a twin-turbocharged 4.2-liter V8 to the CT6 back in 2019 — a hand-built, no-compromise unit that Cadillac's engineers literally assembled by hand, one at a time, like some kind of horsepower artisans. It was so good, so over-engineered, and so wildly impractical for a luxury sedan that Cadillac killed it almost immediately.But the Blackwing has gone on through the years showcasing the amzing engineering of Cadillac, and now, just ahead of the F1 race weekend in Miami this year, the legendary American carmaker has launched something that none of us expected - a more powerful CT5-V Blackwing. 685 HP, Only 26 Units: Cadillac's CT5-V Blackwing F1 Collector Series Is the Ultimate Limited-Edition Muscle Sedan CadillacCadillac looked at their already legendary, already borderline unhinged CT5-V Blackwing and said, "we need something more powerful."And that is how we got the CT5-V Blackwing F1 Collector Series. The monster performance sedan just dropped on the eve of the Formula 1 Miami Grand Prix 2026, which just so happens to be Cadillac's first-ever home race as an F1 team.CadillacHonestly, this is genuinely one of the most exciting collector cars we've seen from an American carmaker in years. Only 26 units. That's the whole run. Your odds of owning one are roughly the same as wining the lottery, which you would probably need to win to even think about getting one of these bad boys in the first place.Under the hood sits the same supercharged 6.2-liter V8 that made the standard Blackwing a legend, but Cadillac and GM Motorsports turned the wick up to produce 685 horsepower and 673 lb-ft of torque — making this the most powerful Blackwing ever built. A Manual Transmission Makes It The Perfect Limited-Edition Performance Car CadillacIt comes exclusively with a 6-speed manual transmission because Cadillac knows what's up, and it ships with the full Precision Package so you can actually take it to a track and embarrass people in Porsches.The whole car is drenched in F1 details. There's a stamped F1 logo on the driver's door, a CNC-machined F1 logo on the supercharger cover, laser-etched FIA badges, 3D-printed F1 logo on the shifter medallion, embossed logos on the headrests, and the Cadillac F1 Team logo on the sill plate. CadillacAesthetically, the car wears Midnight Stone Frost paint with a full monochromatic treatment that mirrors the Cadillac F1 livery. Carbon Flash Metallic wheels, Harbor Gray Metallic brake calipers, carbon fiber lower bodywork with a Switchblade Silver pinstripe, and gloss black badging throughout. It looks like it's doing 80mph standing still. Absolutely unreal fitment.CadillacGM President Mark Reuss called it "a centerpiece in any collection" — which is a very polished way of saying this thing goes stupidly hard.Production kicks off mid-2026 in the U.S. and Canada. All 26 will sell immediately to people who are better connected than you. But hey — at least we'll get to watch one lap a parking lot on Instagram and collectively lose our minds.
