2021 Cadillac XT4 Engine

  The Cadillac XT4 is powered by a 237-horsepower 2.0-liter four-cylinder engine and a nine-speed automatic transmission. The XT4 isn't slow, but it's never overly energetic. The engine is noisy and feels overworked at higher speeds, and acceleration from a standstill is only adequate.

2021 Cadillac XT4 Engine, Transmission, and Performance

All XT4s are powered by a 237-horsepower turbocharged four-cylinder engine. It comes with a nine-speed automatic transmission and either front-wheel drive or all-wheel drive. The 2019 XT4 Sport we tested reached 60 mph in 7.8 seconds, 1.5 seconds slower than the X1. Despite the differences, the XT4 felt quick around town and on the highway. Ignore Cadillac's claim that the XT4 is sporty. It's more of a roadster than a sports car.

So long as the road is relatively smooth, the ride is fine. Rough asphalt stretches transmit a lot of vibrations and sharp impacts into the cabin, especially if you're riding on the optional 20-inch wheels. The steering is also disappointing, as it is neither pleasant nor direct in its action. The only decisive controls on the XT4 are its brakes, which hauled our test car down from 70 mph in our emergency-braking test in 172 feet with one of the firmest brake pedals we've encountered.
