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 A4 Allroad doesn’t offer a back seat reminder.

Over 200 people are killed each year when backed over by motor vehicles. The Terrain has standard Reverse Automatic Braking that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The A4 Allroad doesn’t offer automatic braking for stationary objects directly to the rear.

The Terrain has a standard blind spot warning system that uses sensors to alert the driver to objects in the vehicle’s blind spots where the side view mirrors don’t reveal them and moves the vehicle back into its lane. A system to reveal vehicles in the A4 Allroad’s blind spot costs extra.

To help make backing out of a parking space safer, the Terrain has standard Rear Cross Traffic Alert and Rear Cross Traffic Braking automatically engages the brakes to help avoid a collision. Audi charges extra for Rear Cross-Traffic Assist on the A4 Allroad.

Both the Terrain and the A4 Allroad have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front and rear seatbelt pretensioners, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, rearview cameras and available around view monitors.

GMC’s powertrain warranty covers the Terrain 1 year and 10,000 miles longer than Audi covers the A4 Allroad. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 5 years or 60,000 miles. Coverage on the A4 Allroad 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.

To reliably start during all conditions and help handle large electrical loads, the Terrain has a standard 760-amp battery. The A4 Allroad’s 420-amp battery isn’t as powerful.

To lower fuel costs and make buying fuel easier, the GMC Terrain uses regular unleaded gasoline. The A4 Allroad 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 A4 Allroad 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 A4 Allroad.

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 A4 Allroad doesn’t offer a CVT.

For better ride, handling and brake cooling the Terrain offers optional 19-inch wheels. The A4 Allroad’s largest wheels are only 18-inches.

For better handling and stability, the track (width between the wheels) on the Terrain is 1.9 inches wider in the front and 2.4 inches wider in the rear than on the A4 Allroad.

For better maneuverability, the Terrain’s turning circle is 1.3 feet tighter than the A4 Allroad’s (37.1 feet vs. 38.4 feet).

The GMC Terrain may be more efficient, handle and accelerate better because it weighs about 250 to 400 pounds less than the Audi A4 Allroad.

The Terrain is 6.5 inches shorter than the A4 Allroad, 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 A4 Allroad 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 A4 Allroad doesn’t offer active noise cancellation.

The Terrain has 2.6 inches more front headroom, 1.8 inches more front shoulder room, 1.8 inches more rear headroom, 3.5 inches more rear legroom and 1.2 inches more rear shoulder room than the A4 Allroad.

The Terrain has a much larger cargo volume with its rear seat up than the A4 Allroad with its rear seat up (29.8 vs. 24.2 cubic feet). The Terrain has a much larger cargo volume with its rear seat folded than the A4 Allroad with its rear seat folded (63.5 vs. 58.4 cubic feet).

The Terrain’s optional easy entry system glides the driver’s seat back when the door is unlocked or the ignition is switched off, making it easier for the driver to get in and out. The A4 Allroad doesn’t offer an easy entry system.

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 A4 Allroad has neither an oil pressure gauge nor a temperature gauge.

The Terrain’s standard Keyless Open and Start allow you to unlock the doors from any outside door handle, unlock the cargo door, and start the engine, all without removing the key from the pocket or purse. Keyless Engine Start/Stop standard on the A4 Allroad only offers hands-free access for the ignition, none to unlock the car.

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 A4 Allroad only has an intermittent setting, so in a hard rain visibility isn’t as good.

The Terrain is available in both front-wheel drive and four-wheel drive configurations. The A4 Allroad doesn’t offer a two-wheel drive configuration.

The GMC Terrain outsold the Audi A4/S4 by over five to one during 2023.
