2025 Cadillac CT5-V Blackwing | 682 HP 
If you’re scratching your head wondering why the heck a four-door Cadillac sedan—the Cadillac CT5-V Blackwing—is suddenly on a list of most powerful muscle cars to buy, it’s because under the skin it’s mechanically identical to the 2017–2024 ZL1 Camaro. Same Alpha platform chassis, same magnificent supercharged LT4 powerplant, same selection of six-speed manual/10-speed automatic transmissions. We’ve never driven one here at HOT ROD, so if you want the detailed scoop on this highest-horsepower car we suggest you click here to drill into the details before these cars are all gone. (Speaking of which, the CT5-V Blackwing’s final year of production will be 2025.) Note that the Blackwing is a slightly heftier car than the ZL1, so the LT4 mill has been endowed with a slightly larger supercharger (2.7 liters vs. 1.7 liters) which boosts power from the Camaro’s 650 hp another 32 clicks to 682 hp.
