Both the 2.0-liter four-cylinder and 3.0-liter V6 engines remain unchanged for 2025. The turbocharged four-cylinder will continue to make 237 horsepower and 258 lb-ft of torque, while the twin-turbo V6 will make 335 hp and 405 lb-ft. Rear-wheel drive is standard, with all-wheel drive available; both engines and drive combos utilize a 10-speed automatic transmission.
If you think a midsize luxury sedan sporting a four-cylinder engine is out of the ordinary, remember that BMW, Audi, and Mercedes-Benz all start their midsize sedans off with turbocharged four-cylinder engines too. It is worth noting, however, that the German engines are all more powerful than the Cadillac's offerings in its base cars.
Thankfully for those who crave a performance sedan, Cadillac offers the V and V Blackwing versions of the CT5, which remain just as potent as they did last year. That means the CT5-V uses an uprated version of the turbocharged 3.0-liter V6 that's optional on the regular CT5 and maintains its 360 horsepower and 405 lb-ft of torque. It comes exclusively with a 10-speed automatic transmission and rear- or all-wheel drive. The supercharged 6.2-liter V8 in the CT5-V Blackwing also remains the same and cranks out a delicious 668 horsepower and 659 lb-ft of torque. Buyers can opt for either a six-speed manual or a 10-speed automatic, but the Blackwing is rear-drive only.
