Cadillac is determined to win back domestic buyers from the stranglehold of German sport sedans. Their latest weapons are the 2020 Cadillac CT4 and 2020 Cadillac CT5.

The CT4 and CT5 replace the outgoing ATS and CTS, respectively. Both are sport sedans that aim to bring a luxury experience within easy reach. We took a closer look to see which best fulfills that mission.

What the CT4 Gets Right

As the smaller sedan, the CT4 is also cheaper. Starting just under $34,000, the CT4 is just under $4,000 less than a base CT5.

Even with its price advantage, the CT4 starts with the same engine as the CT5. The 2.0-liter turbocharged four-cylinder engine is better suited to the CT4’s smaller body, with less inertia to overcome.

The other advantage of the CT4’s size is playfulness. The outgoing ATS and CTS were both excellent in the corners, but, so far, it looks like the CT4 inherited more handling ability than the CT5. Cadillac is subtly shifting its larger cars back toward plush comfort, and enthusiasts may prefer the smaller package.

The interiors of these two cars share much in common. The CT5 gets a larger infotainment touchscreen, but the CT4 otherwise closely mirrors its bigger sibling. For those who don’t mind the smaller size, that makes for excellent value.

What the CT5 Gets Right

The CT5’s biggest advantage is size. The second row is more spacious than the outgoing CTS and provides an extra 4.5 inches of rear leg room. The CT5 has more cargo space as well, though not by as much as you might expect.

Both cars start with the same turbo four-cylinder engine, but the CT5 gets the option of a V6. With 335 horsepower and 400 pound-feet of torque, the 3.0-liter twin-turbo V6 gives the CT5 formidable oomph.

As you might expect of the larger car, the CT5 extends further into luxury territory than the CT4. The CT6 still owns the flagship position, but the CT5 still gets access to exclusive features like massage-capable seats. In equivalent trims, the CT5 gets extra standard features like wireless charging and blind-spot monitoring.

Comfort vs. Character

In their newest iterations, Cadillac’s sedans share more parts but less personality. The CT4 and CT5 share an engine and much of their interior feel, but the CT4 continues as a compact sport sedan while the CT5 leans toward a comfortable cruiser.

These are two different purposes, but the CT4 seems closer to the mark. For the price, the materials in the CT5 aren’t as premium as luxury competitors. From a value perspective, the CT4 is the better buy.

Our Verdict: Cadillac CT4

We wish Cadillac the best of luck in taking on the European competition, but if we’re to become converts, we’d rather ride in the Cadillac CT4. The CT5’s extra leg room is welcome, but not at the cost of handling and acceleration. Size matters, but these are sport sedans, after all.
