CarGurus Analysis: 2021 Cadillac CT4
Summary
With 295 currently listed for sale and an average price of $26,227.00, 32.2% of 2021 Cadillac CT4s for sale on CarGurus are rated as good or great deals.
76.9% of 2021 CT4 models on CarGurus are accident free.
Why it stands out
The 2021 Cadillac CT4 stands out as a compact luxury sedan with a distinctly American personality. Its front-engine, rear-wheel-drive layout and stiff chassis give it a true sport-sedan character, and the design is unapologetically Cadillac, with a blocky shape and T-shaped headlights and taillights that separate it from softer-looking rivals. It also offers a choice of turbocharged 2.0-liter or 2.7-liter four-cylinder engines, which helps the CT4 cover both everyday commuting and more energetic driving.
For 2021, the CT4 gained wireless Apple CarPlay and Android Auto compatibility, and forward-collision warning and automatic emergency braking became standard. General Motors’ Super Cruise semi-automated driving tech also became available that year. The CT4’s appeal is strengthened by its available all-wheel drive, its sporty drive modes, and the fact that even the base model includes an 8-inch touchscreen, a digital instrument cluster, and Active Noise Cancellation. Buyers looking for a more performance-focused version will also appreciate that the CT4 lineup includes a V-Series model with a stronger engine, upgraded suspension hardware, and performance-oriented details.
There are trade-offs, though. The base model is described as sluggish, and the back seat is cramped. Even so, the 2021 Cadillac CT4 remains distinctive because it combines rear-drive dynamics, sharp styling, and a strong technology story in a segment where many competitors lean more heavily toward conventional luxury-car formulas.
