For enhanced safety, the GMC Terrain’s rear seat shoulder belts have child comfort guides to move the belt to properly fit children. A better fit can prevent injuries and the increased comfort also encourages children to buckle up. The Acura RDX doesn’t offer comfort guides on its rear seat belts.

In the past twenty years hundreds of infants and young children have died after being left in vehicles, usually by accident. When turning the vehicle off, drivers of the Terrain are reminded to check the back seat if they opened the rear door before starting out. The RDX doesn’t offer a back seat reminder.

Both the Terrain and the RDX have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, front wheel drive, plastic fuel tanks, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, rearview cameras, available all wheel drive, blind spot warning systems, around view monitors and rear cross-path warning.

The National Highway Traffic Safety Administration does 35 MPH front crash tests on new vehicles. In this test, results indicate that the GMC Terrain is safer than the Acura RDX:

The GMC Terrain may be more efficient, handle and accelerate better because it weighs about 250 to 350 pounds less than the Acura RDX.

The Terrain is 4.5 inches shorter than the RDX, making the Terrain easier to handle, maneuver and park in tight spaces.

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 RDX doesn’t offer active grille shutters.

The Terrain’s instruments include an oil pressure gauge and a temperature gauge - which could save your engine! Often ‘idiot lights’ don’t warn you until damage has been done. The RDX does not have an oil pressure gauge.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the GMC Terrain Denali has a standard wireless phone charging system (Qi) in the center console. The RDX doesn’t offer wireless personal charging.

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 RDX doesn’t offer a house-current electrical outlet.

The Terrain Denali’s optional Automatic Parking Assist can parallel park or back into a parking spot by itself, with the driver only controlling speed with the brake pedal. The RDX doesn’t offer an automated parking system.
