CarGurus Analysis: 2021 Cadillac CT4
Summary
With 262 currently listed for sale and an average price of $25,892.00, 32.1% of 2021 Cadillac CT4s for sale on CarGurus are rated as good or great deals.
75.2% of 2021 CT4 models on CarGurus are accident free.
The 2021 Cadillac CT4 continues to impress with its front-engine, rear-wheel-drive layout, sporty performance options, and advanced technology features.
Why it stands out
The 2021 Cadillac CT4 builds on its reputation as a compelling entry in the small luxury sedan market, offering excellent handling characteristics thanks to its rear-wheel-drive architecture, which is derived from the Chevrolet Camaro. Notably, the CT4's turbocharged engine options—including a 2.0-liter with 237 horsepower and a 2.7-liter with 309 to 325 horsepower—provide a power range appealing to performance enthusiasts. The cabin boasts impressive technology, including a standard touchscreen infotainment system with Apple CarPlay and Android Auto. Moreover, with Cadillac's commitment to quality, the CT4 delivers a refined driving experience. However, potential buyers should consider the confined back seat and note that the base model's performance could be sluggish compared to higher trims.
