Compare the2025 Acura RDXVS 2024 Audi Q4 e-tron

The Acura RDX has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags helps prevent the driver and front passenger from sliding under their seatbelts or the main frontal airbags; this keeps them better positioned during a collision for maximum protection. Knee airbags also help keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The Q4 e-tron doesn’t offer knee airbags.

To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the RDX. But it costs extra on the Q4 e-tron.

The RDX’s 2.0 turbo 4-cylinder produces 71 more horsepower (272 vs. 201) and 51 lbs.-ft. more torque (280 vs. 229) than the Q4 40 e-tron’s standard electric motor.

The Acura RDX has standard four-wheel disc brakes for better stopping power and improved directional control in poor weather. Only rear drums come on the Q4 e-tron. Drums can heat up and make stops longer, especially with antilock brakes that work much harder than conventional brakes.

The RDX stops shorter than the Q4 e-tron:

For better traction, the RDX A-Spec’s tires are larger than the largest tires available on the Q4 e-tron (255/45R20 vs. 235/55R19).

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 Q4 e-tron doesn’t offer vehicle monitored tire inflation.

The RDX has a standard space-saver spare (not available on A-Spec) so you can replace a flat tire and drive to have the flat repaired or replaced. A spare tire isn’t available on the Q4 e-tron; it requires you to depend on roadside assistance and your vehicle will have to be towed.

The RDX offers an available driver-adjustable suspension system. It allows the driver to choose between an extra-supple ride, reducing fatigue on long trips, or a sport setting, which allows maximum control for tricky roads or off-road. The Q4 e-tron’s suspension doesn’t offer adjustable shock absorbers.

For better handling and stability, the track (width between the wheels) on the RDX is 1.9 inches wider in the front and 3.2 inches wider in the rear than on the Q4 e-tron.

For greater off-road capability the RDX has a 2.4 inches greater minimum ground clearance than the Q4 e-tron (8.2 vs. 5.8 inches), allowing the RDX to travel over rougher terrain without being stopped or damaged.

The RDX uses computer-generated active noise cancellation to help remove annoying noise and vibration from the passenger compartment, especially at low frequencies. The Q4 e-tron doesn’t offer active noise cancellation.

The RDX has 1.1 inches more front headroom, .4 inches more front legroom, 3 inches more front shoulder room, 1.2 inches more rear legroom and 1.5 inches more rear shoulder room than the Q4 e-tron.

The RDX has a much larger cargo volume with its rear seat up than the Q4 e-tron with its rear seat up (31.1 vs. 24.8 cubic feet). The RDX has a much larger cargo volume with its rear seat folded than the Q4 e-tron with its rear seat folded (79.8 vs. 53.1 cubic feet).

The RDX uses gas struts to support the hood for easier service access. The Q4 e-tron uses a prop rod to support its heavy hood. It takes two hands to open the hood and set the prop rod, the prop rod gets in the way during maintenance and service, and the prop rod could be knocked out, causing the heavy hood to fall on the person maintaining or servicing the car.

J.D. Power and Associates surveys of service recipients show that Acura service is better than Audi. J.D. Power ranks Acura 9th in service department satisfaction (above the industry average). With a 16% lower rating, Audi is ranked 18th.

The RDX’s power window, power lock, power mirror and cruise control switches are lit from behind, making them plainly visible and easier to operate at night. The Q4 e-tron’s cruise control switches are unlit, making them difficult to find at night and operate safely.

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 Q4 e-tron only has an intermittent setting, so in a hard rain visibility isn’t as good.
