Cadillac XT4 vs XT5 vs XT6 Ruston LA

Seating

A big part of picking the right Cadillac SUV is deciding how much room you’ll need for passengers and cargo. The Cadillac XT4 is the smallest of the lineup, followed by the XT5 and then the XT6. Both the XT4 and the XT5 have seating for five passengers, but since the XT5 is slightly larger it offers more room for cargo and passenger comfort. There’s up to 48.9 cubic feet of cargo space behind the front seats in the 2020 XT4, and 63.0 cubic feet in the 2020 XT5 with the rear seatbacks down.

If you need extra space for people and things, the XT6 is probably right for you. This SUV seats up to seven in three rows of seating, with 29.5 feet of third-row legroom, and up to 78.70 cubic feet of cargo space.

Power

The Cadillac XT4 is the most compact of these Cadillac crossovers, and as such it has a more modest engine under its hood. For the 2020 model year, it’s powered by a 2.0-liter turbo 4-cylinder that delivers a generous 237 horsepower and 258 lb-ft of torque.

The Cadillac XT5 sits in the middle in terms of size and power options. For 2020, its standard powertrain is the 2.0-liter turbo engine, but it’s also available with a peppier 3.6-liter V6, which is standard in the XT6 for the 2020 model year.

Extra pep from the V6 provides the acceleration needed to fuel these slightly larger models, and also makes for a versatile towing capacity in the XT6. The 3.6-liter V6 kicks out 310 horsepower and 271 lb-ft of torque. This engine also pairs with a 9-speed automatic transmission. When properly equipped with the Smart Tow Trailering System, the 2020 model of the XT6 can tow up to 4,000 pounds.

Fuel economy

If you want the best possible fuel economy for local and long-distance travel, you should go for the Cadillac XT4. Its smaller size allows it to get more miles to the gallon. For 2020, its standard engine delivers an EPA estimated 26 mpg combined.* Although the larger XT5 and XT6 have slightly less miles to the gallon, their fuel economy is still impressive for crossovers of their respective sizes. The largest model, the Cadillac XT6, delivers an estimated 20 mpg combined, while the XT5 delivers a happy medium at an estimated 24 mpg combined for FWD.**
