The Cadillac XT4 is the smallest SUV in the automaker's lineup. It arrived in 2019 as a compact crossover made for people seeking Cadillac design, quality, features, and technology without the bulk or price of a larger vehicle. The XT4 has a turbocharged four-cylinder engine and available all-wheel drive, and it offers more passenger and cargo room than its exterior dimensions might suggest. Like every member of the Cadillac family, the XT4 conveys affluence and high-tech minimalism. In the XT4, however, those traits are rendered in a bite-size package that is both agile and efficient.
