For enhanced safety, the front and rear seat shoulder belts of the Volvo V90 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 RDX doesn’t offer pretensioners for the rear seat belts.

The V90’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The RDX doesn’t offer pre-crash pretensioners.

Both the V90 and RDX have child safety locks to prevent children from opening the rear doors. The V90 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 RDX’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 V90 offers optional built in child booster seats. They’re more crash worthy than an added child seat because of their direct attachment to the seat. Acura doesn’t offer the convenience and security of a built-in child booster seat in the RDX. Their owners must carry a heavy booster seat in and out of the vehicle; V90 owners can just fold their built-in child seat up or down.

The V90 has a standard Whiplash Protection System (WHIPS), which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the WHIPS moves the headrests forward to prevent neck and spine injuries. At the same time the pretensioning seatbelts fire, removing slack from the belts. The RDX doesn’t offer a whiplash protection system.

The V90 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 RDX 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 V90’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 RDX doesn’t offer a driver alert monitor.

Both the V90 and the RDX 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 V90’s corrosion warranty is 7 years longer than the RDX’s (12 vs. 5 years).

Volvo pays for scheduled maintenance on the V90 for 3 years and 36,000 miles. Volvo will pay for oil changes, lubrication and any other required maintenance. Acura doesn’t pay scheduled maintenance for the RDX.

The RDX’s redline is at 7000 RPM, which causes more engine wear, and a greater chance of a catastrophic engine failure. The V90 has a 6000 RPM redline.

The battery on the V90 is in the trunk, which protects it from hot underhood temperatures that can degrade battery life. By keeping the V90’s battery 20 to 30 degrees cooler, its life is increased by years. The RDX’s battery is in the hot engine compartment.

A reliable vehicle saves its owner time, money and trouble. Nobody wants to be stranded or have to be without a vehicle while it’s being repaired. Consumer Reports rates the V90’s reliability 14 points higher than the RDX.

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.

On the EPA test cycle the V90 T5 FWD gets better fuel mileage than the RDX FWD (22 city/33 hwy vs. 22 city/28 hwy).

Regenerative brakes improve the V90’s fuel efficiency by converting inertia back into energy instead of wasting it. The RDX doesn’t offer a regenerative braking system.

For better traction, the V90 has larger tires than the RDX (255/40R19 vs. 235/55R19).

The V90’s standard tires provide better handling because they have a lower 40 series profile (height to width ratio) that provides a stiffer sidewall than the RDX’s standard 55 series tires. The V90’s optional tires have a lower 35 series profile than the RDX A-Spec’s 40 series tires.

For a smoother ride and more stable handling, the V90’s wheelbase is 7.5 inches longer than on the RDX (115.8 inches vs. 108.3 inches).

The V90’s front to rear weight distribution is more even (53.7% to 46.3%) than the RDX’s (57% to 43%). This gives the V90 more stable handling and braking.

The V90 T6 AWD Inscription handles at .94 G’s, while the RDX A-Spec AWD pulls only .81 G’s of cornering force in a Car and Driver skidpad test.

The V90 T6 AWD Inscription executes Motor Trend’s “Figure Eight” maneuver 1.4 seconds quicker than the RDX AWD (26.3 seconds @ .67 average G’s vs. 27.7 seconds @ .62 average G’s).

Unlike the driver-only memory system in the RDX, the V90 Inscription has a passenger memory, so that when drivers switch, the memory setting adjusts the driver’s seat and outside mirror angle and the front passenger seat also adjusts to the new passenger’s preset preferences.

The V90’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 RDX’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 V90 to prevent washer fluid and nozzles from freezing and help continue to keep the windshield clear in sub-freezing temperatures. The RDX 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 V90 has standard headlight washers to keep headlight output high. The RDX doesn’t offer headlight washers.

To help drivers avoid possible obstacles, the V90 has standard cornering lights to illuminate around corners when the turn signals are activated. The RDX doesn’t offer cornering lights. The V90 also has standard adaptive headlights to illuminate around corners automatically by reading vehicle speed and steering wheel angle.

The V90 Inscription offers optional massaging front seats in order to maximize comfort and eliminate fatigue on long trips. Massaging seats aren’t available in the RDX.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the Volvo V90 has a standard wireless phone charging system (Qi) in the center console. The RDX doesn’t offer wireless personal charging.

The V90’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 RDX doesn’t offer an automated parking system.
