The CT5 compact luxury sedan is launching a car renaissance at Cadillac. Smaller than the CT6, it replaces the CTS. Under the hood is a turbocharged 2.0-litre four-cylinder engine that delivers 237 horsepower or a twin-turbo 3.0-litre V6 good for 335 horsepower. But wait, it gets even better with the CT5-V, which pushes the V6 to 355 horsepower while receiving high-performance components and systems like Brembo brakes. Cadillac’s Super Cruise semi-autonomous driving tech is available, too.
