Safety

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

Warranty

Acura’s powertrain warranty covers the RDX 2 years and 20,000 miles longer than Audi covers the Allroad. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 6 years or 70,000 miles. Coverage on the Allroad ends after only 4 years or 50,000 miles.

Reliability

To reliably start during all conditions and help handle large electrical loads, the RDX has a standard 550-amp battery. The Allroad’s 420-amp battery isn’t as powerful.

J.D. Power and Associates’ 2017 Initial Quality Study of new car owners surveyed provide the statistics that show that Acura vehicles are better in initial quality than Audi vehicles. J.D. Power ranks Acura 19th in initial quality. With 12 more problems per 100 vehicles, Audi is ranked 26th.

Engine

The RDX’s 2.0 turbo 4 cyl. produces 20 more horsepower (272 vs. 252) and 7 lbs.-ft. more torque (280 vs. 273) than the Allroad’s 2.0 turbo 4 cyl.

Fuel Economy and Range

The RDX has 1.8 gallons more fuel capacity than the Allroad (17.1 vs. 15.3 gallons), for longer range between fill-ups.

The RDX 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 Allroad doesn’t offer a cap-less fueling system.

Transmission

A 10-speed automatic is standard on the Acura RDX, for better acceleration and lower engine speed on the highway. Only a seven-speed automatic is available for the Allroad.

Tires and Wheels

For better traction, the RDX A-Spec’s tires are larger than the largest tires available on the Allroad (255/40R20 vs. 245/45R18).

The RDX A-Spec’s tires provide better handling because they have a lower 40 series profile (height to width ratio) that provides a stiffer sidewall than the Allroad’s 45 series tires.

For better ride, handling and brake cooling the RDX has standard 19-inch wheels. Only 18-inch wheels are available on the Allroad. The RDX A-Spec has standard 20-inch wheels.

The RDX has a standard easy tire fill system. When inflating the tires, the vehicle’s integrated tire pressure sensors keep track of the pressure as the tires fill and tell the driver when the tires are inflated to the proper pressure. The Allroad doesn’t offer vehicle monitored tire inflation.

Suspension and Handling

For better handling and stability, the track (width between the wheels) on the RDX is 2.1 inches wider in the front and 3 inches wider in the rear than on the Allroad.

For greater off-road capability the RDX has a 1.7 inches greater minimum ground clearance than the Allroad (8.2 vs. 6.5 inches), allowing the RDX to travel over rougher terrain without being stopped or damaged.

Chassis

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

Passenger Space

The RDX has 12 cubic feet more passenger volume than the Allroad (104 vs. 92).

The RDX has .4 inches more front headroom, .3 inches more front legroom, 3.8 inches more front shoulder room, .1 inches more rear headroom, 2.7 inches more rear legroom and 2.1 inches more rear shoulder room than the Allroad.

Cargo Capacity

The RDX has a much larger cargo area with its rear seat up than the Allroad with its rear seat up (31.1 vs. 24.2 cubic feet). The RDX has a much larger cargo area with its rear seat folded than the Allroad with its rear seat folded (79.8 vs. 58.5 cubic feet).

Pressing a switch automatically lowers the RDX’s rear seats, to make changing between passengers and cargo easier. The Allroad doesn’t offer automatic folding seats.

To make loading groceries and cargo easier when your hands are full, the RDX Advance’s liftgate can be opened and closed just by kicking your foot under the back bumper, leaving your hands completely free. The Allroad doesn’t offer a hands-free gesture to open its trunk, forcing you to put cargo down if your hands are full.

Ergonomics

The RDX has a standard remote vehicle starting system, so the vehicle can be started from inside the driver's house. This allows the driver to comfortably warm up the engine before going out to the vehicle. The climate system will also automatically heat or cool the interior. The Allroad doesn’t offer a remote starting system.

If the windows are left open on the RDX the driver can close them all at the outside door handle or from a distance using the remote. On a hot day the driver can lower the windows from a distance using the keyless remote. The driver of the Allroad can’t use the remote to operate the windows.

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

When the RDX is put in reverse, both rearview mirrors tilt from their original position. This gives the driver a better view of the curb during parallel parking maneuvers. Shifting out of reverse puts the mirrors into their original positions. The Allroad’s mirrors don’t automatically adjust for backing.

Model Availability

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

Recommendations

The Car Book by Jack Gillis recommends the Acura RDX, based on economy, maintenance, safety and complaint levels. The Audi Allroad isn't recommended.

The Acura RDX outsold the Audi Allroad by almost 16 to one during 2017.
