Compare the2022 Audi e-tronVS 2022 Acura MDX

The e-tron’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The MDX doesn’t offer pre-crash pretensioners.

Both the e-tron and MDX have child safety locks to prevent children from opening the rear doors. The e-tron has power child safety locks, allowing the driver to activate and deactivate them from the driver's seat and to know when they're engaged. The MDX’s child locks have to be individually engaged at each rear door with a manual switch. The driver can’t know the status of the locks without opening the doors and checking them.

The e-tron’s standard pretensioning seatbelts also sense rear collisions and remove slack from the seatbelts to help protect the occupants from whiplash and other injuries. The MDX doesn’t offer a whiplash protection system.

The e-tron has a standard Secondary Collision Brake Assist, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The MDX doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.

To allow off-road and deep snow capability, Four-Wheel Drive is standard on the e-tron. But it costs extra on the MDX.

When descending a steep, off-road slope, the e-tron’s standard Hill Descent Control allows you to creep down safely. The MDX doesn’t offer Hill Descent Control.

An active infrared night vision system optional on the e-tron helps the driver to more easily detect people, animals or other objects in front of the vehicle at night. Using an infrared camera and near-infrared lights to detect heat, the system then displays the image on a monitor in the dashboard. The MDX doesn’t offer a night vision system.

Both the e-tron and the MDX 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, 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.

The Audi e-tron weighs 1200 to 1803 pounds more than the Acura MDX. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.

The e-tron’s corrosion warranty is 7 years longer than the MDX’s (12 vs. 5 years).

There are over 12 percent more Audi dealers than there are Acura dealers, which makes it easier should you ever need service under the e-tron’s warranty.

From surveys of all its subscribers, Consumer Reports’ January 2021 Auto Issue reports that Audi vehicles are more reliable than Acura vehicles. Consumer Reports ranks Audi 14 places higher in reliability than Acura.

The e-tron’s standard electric motors produce 112 more horsepower (402 vs. 290) and 223 lbs.-ft. more torque (490 vs. 267) than the MDX’s 3.5 SOHC V6. The e-tron S’ standard electric motors produce 206 more horsepower (496 vs. 290) and 450 lbs.-ft. more torque (717 vs. 267) than the MDX’s 3.5 SOHC V6.

As tested in Motor Trend the Audi e-tron (base engine) is faster than the Acura MDX:

On the EPA test cycle the e-tron gets better mileage than the MDX:

The e-tron’s maximum EPA estimated driving range is 181 to 222 miles on a full charge. The MDX has to start its internal combustion engine to move.

Regenerative brakes improve the e-tron’s fuel efficiency by converting inertia back into energy instead of wasting it. The MDX doesn’t offer a regenerative braking system.

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Audi e-tron higher (10 out of 10) than the Acura MDX (5). This means the e-tron produces up to 19.8 pounds less smog-producing pollutants than the MDX every 15,000 miles.

The e-tron’s launch control uses engine electronics to hold engine RPM’s precisely in order to provide the most stable and rapid acceleration possible, using all of the available traction. The MDX doesn’t offer launch control.

For better stopping power the e-tron’s brake rotors are larger than those on the MDX:

The e-tron’s standard front and rear disc brakes are vented to help dissipate heat for shorter stops with less fading. The rear discs on the MDX are solid, not vented.

The e-tron stops shorter than the MDX:

For better traction, the e-tron’s optional tires are larger than the largest tires available on the MDX (265/45R21 vs. 255/55R19).

The e-tron’s standard tires provide better handling because they have a lower 50 series profile (height to width ratio) that provides a stiffer sidewall than the MDX’s standard 55 series tires. The e-tron’s optional tires have a lower 45 series profile than the MDX’s optional 50 series tires.

For better ride, handling and brake cooling the e-tron has standard 20-inch wheels. Smaller 19-inch wheels are standard on the MDX. The e-tron’s optional 21-inch wheels are larger than the 20-inch wheels optional on the MDX.

The front and rear suspension of the e-tron uses air springs for a smoother, controlled ride than the MDX, which uses coil springs. Air springs maintain proper ride height and ride more smoothly.

The e-tron has a standard 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 MDX’s suspension doesn’t offer adjustable shock absorbers.

The e-tron has a standard automatic front and rear load leveling suspension to keep ride height level with a heavy load or when towing. The e-tron’s height leveling suspension allows the driver to raise ride height for better off-road clearance and then lower it again for easier entering and exiting and better on-road handling. The MDX doesn’t offer a load leveling suspension.

For a smoother ride and more stable handling, the e-tron’s wheelbase is 1.3 inches longer than on the MDX (115.1 inches vs. 113.8 inches).

The e-tron Chronos Edition executes Motor Trend’s “Figure Eight” maneuver quicker than the MDX SH-AWD (26.6 seconds @ .71 average G’s vs. 27.2 seconds @ .63 average G’s).

The e-tron is 5.4 inches shorter than the MDX, making the e-tron easier to handle, maneuver and park in tight spaces.

The front grille of the e-tron uses electronically controlled shutters to close off airflow and reduce drag when less engine cooling is needed. This helps improve highway fuel economy. The MDX doesn’t offer active grille shutters.

The e-tron has .5 inches more rear headroom and .6 inches more rear legroom than the MDX.

The e-tron has a much larger cargo volume than the MDX with its rear seat up (28.5 vs. 18.1 cubic feet).

Pulling a handle automatically lowers the e-tron’s rear seats, to make changing between passengers and cargo easier. The MDX doesn’t offer automatic folding seats.

The e-tron’s standard towing capacity is much higher than the MDX’s (4000 vs. 3500 pounds).

The power windows standard on both the e-tron and the MDX have locks to prevent small children from operating them. When the lock on the e-tron is engaged the driver can still operate all of the windows, for instance to close one opened by a child. The MDX prevents the driver from operating the other windows just as it does the other passengers.

The e-tron’s rain-sensitive wipers adjust their speed and turn on and off automatically based on the amount of rainfall on the windshield. This allows the driver to concentrate on driving without constantly adjusting the wipers. The MDX’s standard intermittent wipers change speed with vehicle speed, but can’t turn on and off or change speed based on changing rainfall.

The e-tron’s standard rear and side view mirrors have an automatic dimming feature. These mirrors can be set to automatically darken quickly when headlights shine on them, keeping following vehicles from blinding or distracting the driver. The MDX has an automatic rear view mirror, but its side mirrors don’t dim.

The e-tron 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 MDX.

The e-tron Prestige has standard massaging front seats in order to maximize comfort and eliminate fatigue on long trips. Massaging seats aren’t available in the MDX.
