For enhanced safety, the front and middle seat shoulder belts of the Volvo XC90 have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The Acura MDX doesn’t offer pretensioners for the middle seat belts.

For enhanced safety, the front and middle seat shoulder belts of the Volvo XC90 are height-adjustable to accommodate a wide variety of driver and passenger heights. A better fit can prevent injuries and the increased comfort also encourages passengers to buckle up. The Acura MDX doesn’t offer height-adjustable middle seat belts.

Both the XC90 and MDX have child safety locks to prevent children from opening the rear doors. The XC90 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 Volvo XC90 offers an optional built in child booster seat. It’s more crash worthy than an added child seat because of its direct attachment to the seat. Acura doesn’t offer the convenience and security of a built-in child booster seat in the MDX. Their owners must carry a heavy booster seat in and out of the vehicle; XC90 owners can just fold their built-in child seat up or down.

Using vehicle speed sensors and seat sensors, smart airbags in the XC90 deploy with different levels of force or don’t deploy at all to help better protect passengers of all sizes in different collisions. The XC90’s side airbags will shut off if a child is leaning against the door. The MDX’s airbags don’t have smart features and will always deploy full force.

The XC90 has a standard Whiplash Protection System (WHIPS), which use a specially designed seat to protect the driver and front passenger from whiplash. During a rear-end collision, the WHIPS allows the backrest to travel backwards to cushion the occupants and the headrests move forward to prevent neck and spine injuries. At the same time the pretensioning seatbelts fire, removing slack from the belts. The MDX doesn’t offer a whiplash protection system.

The XC90 has standard Automatic Braking After Collision, which automatically apply 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.

The XC90’s driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The MDX doesn’t offer a driver alert monitor.

Both the XC90 and the MDX have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front wheel drive, 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, lane departure warning systems, rearview cameras and available around view monitors.

The National Highway Traffic Safety Administration does side impact tests on new vehicles. In this test, which crashes the vehicle into a flat barrier at 38.5 MPH and into a post at 20 MPH, results indicate that the Volvo XC90 is safer than the Acura MDX:

For its top level performance in IIHS driver-side small overlap frontal, moderate overlap frontal, side impact, rear impact and roof-crush tests, its standard front crash prevention system, its “Good” rating in the new passenger-side small overlap crash test, and its headlight’s “Acceptable” rating, the Insurance Institute for Highway Safety grants the XC90 the rating of “Top Pick” for 2019, a rating granted to only 132 vehicles tested by the IIHS. The MDX has not been fully tested, yet.

To reliably power the ignition and other systems and to recharge the battery, the XC90 has a standard 210-amp alternator. The MDX’s 150-amp alternator isn’t as powerful.

The battery on the XC90 is in the trunk, which protects it from hot underhood temperatures that can degrade battery life. By keeping the XC90’s battery 20 to 30 degrees cooler, its life is increased by years. The MDX’s battery is in the hot engine compartment.

From surveys of all its subscribers, Consumer Reports’ December 2019 Auto Issue reports that Volvo vehicles are more reliable than Acura vehicles. Consumer Reports ranks Volvo 4 places higher in reliability than Acura.

For better traction, the XC90’s optional tires are larger than the largest tires available on the MDX (275/45R20 vs. 265/45R20).

The XC90’s standard tires provide better handling because they have a lower 55 series profile (height to width ratio) that provides a stiffer sidewall than the MDX’s standard 60 series tires. The XC90’s optional tires have a lower 35 series profile than the MDX A-Spec’s 45 series tires.

For better ride, handling and brake cooling the XC90 has standard 19-inch wheels. Smaller 18-inch wheels are standard on the MDX. The XC90’s optional 22-inch wheels are larger than the 20-inch wheels optional on the MDX.

The XC90 R-Design/Inscription has a standard automatic front and rear load leveling suspension to keep ride height level with a heavy load or when towing. The XC90’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 XC90’s wheelbase is 6.5 inches longer than on the MDX (117.5 inches vs. 111 inches).

The XC90’s front to rear weight distribution is more even (51.7% to 48.3%) than the MDX’s (57% to 43%). This gives the XC90 more stable handling and braking.

The XC90 T6 AWD handles at .84 G’s, while the MDX SH-AWD pulls only .82 G’s of cornering force in a Car and Driver skidpad test.

For greater off-road capability the XC90 has a greater minimum ground clearance than the MDX (8.3 vs. 7.3 inches), allowing the XC90 to travel over rougher terrain without being stopped or damaged. The XC90 w/Air Suspension’s minimum ground clearance is 2.6 inches higher than on the MDX (9.9 vs. 7.3 inches).

The XC90 has a standard third row seat which folds flat into the floor. This completely clears a very large cargo area quickly. The MDX doesn’t offer seats that fold into the floor.

Pressing a switch automatically lowers or raises the XC90’s optional third row seats, to make changing between cargo and passengers easier. The MDX doesn’t offer automatic folding seats.

To make loading groceries and cargo easier when your hands are full, the XC90’s liftgate can be opened and closed just by kicking your foot under the back bumper, leaving your hands completely free. The MDX doesn’t offer a hands-free gesture to open its liftgate, forcing you to put cargo down if your hands are full.

The power windows standard on both the XC90 and the MDX have locks to prevent small children from operating them. When the lock on the XC90 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 XC90’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 MDX’s power mirror switches are unlit, making them difficult to find at night and operate safely.

The XC90’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.

Heated windshield washer nozzles are optional on the XC90 to prevent washer fluid and nozzles from freezing and help continue to keep the windshield clear in sub-freezing temperatures. The MDX doesn’t offer heated windshield washer nozzles.

In poor weather, headlights can lose their effectiveness as grime builds up on their lenses. This can reduce visibility without the driver realizing. The XC90 has standard headlight washers to keep headlight output high. The MDX doesn’t offer headlight washers.

To help drivers avoid possible obstacles, the XC90 has standard cornering lights to illuminate around corners when the turn signals are activated. The MDX doesn’t offer cornering lights. The XC90 also has standard adaptive headlights to illuminate around corners automatically by reading vehicle speed and steering wheel angle.

A manual rear sunshade and rear side window sunshades are optional in the XC90 to help block heat and glare for the rear passengers. The MDX doesn’t offer a rear sunshade.

The XC90 Inscription offers optional massaging front seats in order to maximize comfort and eliminate fatigue on long trips. Massaging seats aren’t available in the MDX.

The XC90 R-Design/Inscription’s optional Park Assist Pilot can parallel park or back into a parking spot by itself, with the driver only controlling speed with the brake pedal. The MDX doesn’t offer an automated parking system.
