For its top level performance in all IIHS frontal, side, rear impact and roof-crush tests, and with its optional front crash prevention system, the Insurance Institute for Highway Safety grants the Terrain the rating of “Top Pick” for 2017, a rating granted to only 157 vehicles tested by the IIHS. The XT4 has not been tested, yet.


There are over 89 percent more GMC dealers than there are Cadillac dealers, which makes it much easier should you ever need service under the Terrain’s warranty.

Consumer Reports

Suspension and Handling

For better maneuverability, the Terrain w/17” wheels’ turning circle is .6 feet tighter than the XT4’s (37.4 feet vs. 38 feet).

For greater off-road capability the Terrain SLE has a greater minimum ground clearance than the XT4 (6.9 vs. 6.8 inches), allowing the Terrain to travel over rougher terrain without being stopped or damaged. The Terrain SLT/Denali’s minimum ground clearance is 1.1 inches higher than on the XT4 (7.9 vs. 6.8 inches).


The GMC Terrain may be more efficient, handle and accelerate better because it weighs about 100 to 200 pounds less than the Cadillac XT4.

The front grille of the Terrain uses electronically controlled shutters to close off airflow and reduce drag when less engine cooling is needed. This helps improve highway fuel economy. The XT4 doesn’t offer active grille shutters.

Passenger Space

The Terrain has 2.2 cubic feet more passenger volume than the XT4 (103.2 vs. 101).

The Terrain has .6 inches more front headroom, .5 inches more front legroom, .2 inches more front shoulder room, .2 inches more rear headroom, .2 inches more rear legroom, 2 inches more rear hip room and .5 inches more rear shoulder room than the XT4.

For enhanced passenger comfort on long trips the Terrain’s rear seats recline. The XT4’s rear seats don’t recline.

Cargo Capacity

The Terrain has a much larger cargo volume with its rear seat up than the XT4 with its rear seat up (29.6 vs. 22.5 cubic feet). The Terrain has a much larger cargo volume with its rear seat folded than the XT4 with its rear seat folded (63.3 vs. 48.9 cubic feet).

Pressing a switch automatically lowers the Terrain SLE/SLT/Denali’s rear seats, to make changing between passengers and cargo easier. The XT4 doesn’t offer automatic folding seats.


The Terrain (except SL) offers an optional 115-volt a/c outlet on the center console, allowing you to recharge a laptop or run small household appliances without special adapters that can break or get misplaced. The XT4 doesn’t offer a house-current electrical outlet.


The GMC Terrain outsold the Cadillac XT4 by almost 15 to one during 2018.
