2021 Cadillac CT5 Review: American Modesty

by Aiden Eksteen

The roar of a V6 or V8 engine is typically American, and Cadillac has proven its capability at building sedans that are both plush and powerful. And, while the Blackwing brothers of the milder CT5 sibling take the cake when it comes to pure power, the 2021 Cadillac CT5 still has something to offer. The base engine is a slightly lethargic 2.0-liter turbo-four, but you have access to a more appropriately American 3.0-liter twin-turbo V6 on the Premium Luxury trim, which gives the driver a healthy 335 horsepower and 400 lb-ft of torque. This enables a 0-60 sprint time of around five seconds, depending on drivetrain. And, while this isn't awful, it's still not on the level of some rivals. At least the humble CT5 is a looker with loads of standard features, at a really reasonable price. This goes a long way to distract you from a cabin that feels rather cheap in some places. Still, if your desire is for a fun and engaging sedan, the BMW 3 Series or the Audi A4 sedans will be better picks.

Verdict: 🏁Is the 2021 Cadillac CT5 a good sedan?

The first-generation CT5 is a really impressive luxury midsize sedan for the price Cadillac presents it at, although it doesn't quite offer the performance proficiencies of its predecessor. It's a pretty handsome vehicle and it boasts a spacious and comfortable interior that looks and feels high quality - for the most part. We found a few low-grade bits and pieces here and there, but the cabin is well built and plush enough to stay in competition with some of the CT5's European rivals. The base turbo-four motor is a major disappointment, however, lacking in power and fuel efficiency. The optional twin-turbo V6 unit is a much better option.

All models are refined on the road, though, with a well-insulated cabin that absorbs road abrasions and road noise, and is thoroughly loaded with value. The 2021 Cadillac CT5 underwent review by the NHTSA and scored exceptionally well, with a full house of top mars. Although two recalls exist for this model year - both pertaining to potential airbag malfunctions - ratings from J.D. Power are high, with a score of 85 out of 100 for quality and reliability. The CT5 may not be as proficient or engaging as its European 4-door contemporaries, but for the price it's offered at, it can't be ignored.
