Compare the2026 GMC TerrainVS 2025 Audi new Q5

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 new Q5 doesn’t offer a back seat reminder.

Both the Terrain and the new Q5 have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, blind spot warning systems, rearview cameras, rear cross-path warning and available around view monitors.

GMC’s powertrain warranty covers the Terrain 1 year and 10,000 miles longer than Audi covers the new Q5. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 5 years or 60,000 miles. Coverage on the new Q5 ends after only 4 years or 50,000 miles.

There are over 5 times as many GMC dealers as there are Audi dealers, which makes it much easier should you ever need service under the Terrain’s warranty.

J.D. Power and Associates’ 2025 Initial Quality Study of new car owners surveyed provide the statistics that show that GMC vehicles are better in initial quality than Audi vehicles. With 70 fewer problems per 100 vehicles, JD Power ranks GMC higher than Audi.

J.D. Power and Associates’ 2025 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that GMC vehicles are more reliable than Audi vehicles. J.D. Power ranks GMC above average in long-term dependability. With 21 more problems per 100 vehicles in the first three years of ownership, Audi is rated below average.

To lower fuel costs and make buying fuel easier, the GMC Terrain uses regular unleaded gasoline. The new Q5 requires premium for maximum efficiency, which can cost on average about 84.9 cents more per gallon.

The Terrain has a standard cap-less fueling system. The fuel filler is automatically opened when the fuel nozzle is inserted and automatically closed when it’s removed. This eliminates the need to unscrew and replace the cap and it reduces fuel evaporation, which causes pollution. The new Q5 doesn’t offer a cap-less fueling system.

An eight-speed automatic is standard on the GMC Terrain AWD, for better acceleration and lower engine speed on the highway. Only a seven-speed automatic is available for the new Q5.

The Terrain FWD has a standard continuously variable transmission (CVT). With no “steps” between gears, it can keep the engine at the most efficient speed for fuel economy, or keep it at its peak horsepower indefinitely for maximum acceleration. The new Q5 doesn’t offer a CVT.

The Terrain has a standard space-saver spare tire so you can replace a flat tire and drive to have the flat repaired or replaced. A spare tire isn’t available on the new Q5; it requires you to depend on its run-flat tires, which limits mileage and speed before they are repaired. If a run-flat is damaged beyond repair by a road hazard your vehicle will have to be towed.

For better maneuverability, the Terrain’s turning circle is 1.6 feet tighter than the new Q5’s (37.1 feet vs. 38.7 feet).

The GMC Terrain may be more efficient, handle and accelerate better because it weighs about 500 to 800 pounds less than the Audi new Q5.

The Terrain is 4.7 inches shorter than the new Q5, 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 new Q5 doesn’t offer active grille shutters.

The Terrain uses computer-generated active noise cancellation to help remove annoying noise and vibration from the passenger compartment, especially at low frequencies. The new Q5 doesn’t offer active noise cancellation.

The Terrain has 2.4 inches more front headroom, 3.1 inches more front legroom, 1.4 inches more rear headroom and 1.7 inches more rear legroom than the new Q5.

The front step up height for the Terrain is .6 inches lower than the new Q5 (18.4” vs. 19”). The Terrain’s rear step up height is 1.7 inches lower than the new Q5’s (18” vs. 19.7”).

The Terrain has a much larger cargo volume with its rear seat up than the new Q5 with its rear seat up (29.8 vs. 27.6 cubic feet). The Terrain has a much larger cargo volume with its rear seat folded than the new Q5 with its rear seat folded (63.5 vs. 57.1 cubic feet).

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 new Q5 does not have an oil pressure gauge.

To improve rear visibility by keeping the rear window clear, the Terrain has a standard rear fixed intermittent wiper with a full on position. The rear wiper standard on the new Q5 only has an intermittent setting, so in a hard rain visibility isn’t as good.

The Terrain has a standard heated steering wheel to take the chill out of steering on extremely cold winter days before the vehicle heater warms up. A heated steering wheel costs extra on the new Q5.

The Terrain is available in both front-wheel drive and four-wheel drive configurations. The new Q5 doesn’t offer a two-wheel drive configuration.

The GMC Terrain outsold the Audi Q5/SQ5 by 56% during 2024.
