What You Will Like

The CT4 holds legitimate appeal as a solid entry-luxury compact car in a class with established rivals in this German-dominated segment. The CT4's key rivals include the Audi A3, BMW 2-series Gran Coupe, and the Mercedes Benz A-class. The vital difference between the CT4 versus its German counterparts is the rear-wheel drive platform, which provides the CT4 with a more genuinely sporty feel from the get-go compared to the basic front-wheel drive chassis arrangements found in the competition.

What's New For 2021

The Cadillac CT4 carries over into 2021 with a host of new equipment changes in its second model year to attract more luxury shoppers to the sporty coupe platform. The first custom trim package to be rolled out for the CT4 is the Diamond Sky Special Edition Package. The new and optional Technology Package will offer a configurable, fully digital 12-inch instrument panel. Super Cruise will be offered as a convenient, reliable semi-autonomous driving system. Previously optional automated emergency braking and pedestrian detection are now standard equipment. Finally, the CT4-V Blackwing will make its debut for performance driving enthusiasts.
