Why it stands out

The 2021 Cadillac CT4 distinguishes itself in the compact luxury sedan segment by blending performance with style, making it a compelling choice for buyers looking for an American alternative to European rivals like the Audi A3 and BMW 2 Series. With a choice between rear-wheel drive and optional all-wheel drive, the CT4 caters to driving enthusiasts who appreciate a spirited driving experience. The two turbocharged engine options, including a high-performance 3.6-liter twin-turbo V6 in the CT4-V model, provide ample power for those seeking thrills on the road. Inside, the CT4 is equipped with impressive technology, including an 8-inch touchscreen infotainment system with Apple CarPlay and Android Auto.
