The S90’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Prius Prime doesn’t offer pre-crash pretensioners.

Both the S90 and Prius Prime have child safety locks to prevent children from opening the rear doors. The S90 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 Prius Prime’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 S90 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. Toyota doesn’t offer the convenience and security of a built-in child booster seat in the Prius Prime. Their owners must carry a heavy booster seat in and out of the vehicle; S90 owners can just fold their built-in child seat up or down.

The Volvo S90 has a standard driver’s side knee airbag mounted low on the dashboard. The knee airbag helps prevent the driver from sliding under the seatbelts or the main frontal airbag; this keeps the driver better positioned during a collision for maximum protection. A knee airbag also helps keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The Prius Prime doesn’t offer knee airbags.

The S90 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 Prius Prime doesn’t offer a whiplash protection system.

The S90 has all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The Prius Prime doesn’t offer all-wheel drive.

To help make backing out of a parking space safer, the S90 has standard Cross Traffic Alert with Braking Intervention, systems which detect vehicles approaching from the sides and can automatically apply the brakes to prevent a collision. Parking Support Brake costs extra on the Prius Prime.

Both the S90 and the Prius Prime have standard driver and passenger frontal airbags, front and rear side-impact airbags, side-impact head airbags, front and rear seatbelt pretensioners, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, post-collision automatic braking systems, daytime running lights, lane departure warning systems, blind spot warning systems, rearview cameras, rear cross-path warning and driver alert monitors.

The Volvo S90 weighs 725 to 1212 pounds more than the Toyota Prius Prime. The NHTSA advises that heavier cars are much safer in collisions than their significantly lighter counterparts.

For its top level performance in IIHS driver and passenger-side small overlap frontal, moderate overlap frontal, side impact, roof strength and head restraint tests, its standard vehicle-to-vehicle front crash prevention system, its standard vehicle-to-pedestrian front crash prevention system, and its standard headlight’s “Acceptable” rating, the Insurance Institute for Highway Safety grants the S90 its highest rating: “Top Safety Pick Plus” for 2022, a rating granted to only 128 vehicles tested by the IIHS. The Prius Prime has not been tested, yet.

Warranty

The S90 comes with a full 4-year/50,000-mile basic warranty, which covers the entire car and includes 24-hour roadside assistance. The Prius Prime’s 3-year/36,000-mile basic warranty expires 1 year or 14,000 miles sooner.

The S90’s corrosion warranty is 7 years longer than the Prius Prime’s (12 vs. 5 years).

Volvo pays for scheduled maintenance on the S90 for 1 year and 11000 miles longer than Toyota pays for maintenance for the Prius Prime (3/36,000 vs. 2/25000).

Engine

The S90 B6’s standard 2.0 turbo/supercharged 4-cylinder hybrid produces 75 more horsepower (295 vs. 220) than the Prius Prime’s 2.0 DOHC 4-cylinder hybrid. The S90 T8’s standard 2.0 turbo/supercharged 4-cylinder hybrid produces 235 more horsepower (455 vs. 220) than the Prius Prime’s 2.0 DOHC 4-cylinder hybrid.

Fuel Economy and Range

In heavy traffic or at stoplights the S90’s engine automatically turns off when the vehicle is stopped, saving fuel and reducing pollution. The engine is automatically restarted when the driver gets ready to move again. If the conditions warrant or the driver wishes, the system can be manually disabled at any time for the duration of a trip (not available T8). The Prius Prime doesn’t offer an automatic engine start/stop system.

The S90 has 5.3 gallons more fuel capacity than the Prius Prime (15.9 vs. 10.6 gallons), for longer range between fill-ups.

The S90 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 Prius Prime doesn’t offer a cap-less fueling system.

Brakes and Stopping

For better stopping power the S90’s brake rotors are larger than those on the Prius Prime:

	S90	Prius Prime
Front Rotors	13.6 inches	12 inches
Rear Rotors	12.6 inches	11 inches

The S90’s standard front and rear disc brakes are vented to help dissipate heat for shorter stops with less fading. The rear discs on the Prius Prime are solid, not vented.

Tires and Wheels

For better traction, the S90 has larger tires than the Prius Prime (255/35R20 vs. 195/60R17).

The S90’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 Prius Prime SE’s standard 60 series tires. The S90’s optional tires have a lower 35 series profile than the Prius Prime XSE’s 50 series tires.

For better ride, handling and brake cooling the S90 has standard 19-inch wheels. Smaller 17-inch wheels are standard on the Prius Prime SE. The S90’s optional 20-inch wheels are larger than the 19-inch wheels on the Prius Prime XSE.

The S90 B6 has a standard space-saver spare (not available on Recharge) so you can replace a flat tire and drive to have the flat repaired or replaced. A spare tire isn’t available on the Prius Prime; it requires you to depend on roadside assistance and your vehicle will have to be towed.

Suspension and Handling

The S90 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. The Prius Prime’s suspension doesn’t offer adjustable shock absorbers.

For a smoother ride and more stable handling, the S90’s wheelbase is 12.2 inches longer than on the Prius Prime (120.5 inches vs. 108.3 inches).

For better handling and stability, the track (width between the wheels) on the S90 is 2.2 inches wider in the front and 1.5 inches wider in the rear than on the Prius Prime.

Passenger Space

The S90 has 10.8 cubic feet more passenger volume than the Prius Prime (102 vs. 91.2).

The S90 has 1.7 inches more front hip room, 2.2 inches more front shoulder room, 1.4 inches more rear headroom, 4.5 inches more rear legroom, 3.2 inches more rear hip room and 2.6 inches more rear shoulder room than the Prius Prime.

Cargo Capacity

Pressing a button automatically lowers the S90’s rear seats, to make changing between passengers and cargo easier. The Prius Prime doesn’t offer automatic folding seats.

With its sedan body style, locking rear seatbacks and remote trunk release lockout, the S90 offers cargo security. The Prius Prime’s hatchback body style, non-lockable folding seat and non-lockable remote release defeat cargo security.

A standard locking glovebox keeps your small valuables safer in the S90. The Prius Prime doesn’t offer locking storage for small valuables.

To make loading groceries and cargo easier when your hands are full, the S90’s trunk can be opened and closed just by kicking your foot under the back bumper, leaving your hands completely free. The Prius Prime doesn’t offer a hands-free gesture to open its liftgate, forcing you to put cargo down if your hands are full.

Servicing Ease

The S90 uses gas struts to support the hood for easier service access. The Prius Prime 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.

Ergonomics

The S90 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 Prius Prime doesn’t offer a remote starting system.

Unlike the driver-only memory seat in the Prius Prime XSE Premium, the S90 Ultimate 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 S90 Ultimate has a standard heads-up display that projects speed and navigation instruction readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The Prius Prime doesn’t offer a heads-up display.

Heated windshield washer nozzles are standard on the S90 to prevent washer fluid and nozzles from freezing and help continue to keep the windshield clear in sub-freezing temperatures. The Prius Prime 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 S90 has standard headlight washers to keep headlight output high. The Prius Prime doesn’t offer headlight washers.

The S90 has a standard automatic headlight on/off feature. When the ignition is on, the headlights automatically turn on at dusk and off after dawn. The Prius Prime has an automatic headlight on/off feature standard only on the XSE.

To help drivers avoid possible obstacles, the S90 has standard cornering lights to illuminate around corners when the turn signals are activated. The Prius Prime doesn’t offer cornering lights. The S90 also has standard adaptive headlights to illuminate around corners automatically by reading vehicle speed and steering wheel angle.

A power rear sunshade and rear side window sunshades are standard in the S90 to help block heat and glare for the rear passengers. The Prius Prime doesn’t offer a rear or rear side window sunshades.

When the S90 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 Prius Prime’s mirrors don’t automatically adjust for backing.

The S90’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 Prius Prime offers an automatic rear view mirror, but its side mirrors don’t dim.

The S90 Ultimate has standard front air conditioned seats and offers them optionally in the rear. This keeps the passengers comfortable and takes the sting out of hot seats in summer. The Prius Prime doesn’t offer air-conditioned seats in the rear.

The S90 Ultimate offers optional massaging front seats in order to maximize comfort and eliminate fatigue on long trips. Massaging seats aren’t available in the Prius Prime.

The S90’s standard dual zone air conditioning allows the driver and front passenger to choose two completely different temperatures so people with different temperature preferences won’t have to compromise. This makes both the driver and front passenger as comfortable as possible. The Prius Prime doesn’t offer dual zone air conditioning.

Both the S90 and the Prius Prime offer rear vents. For greater rear passenger comfort, the S90 has standard rear air conditioning vents to keep rear occupants cool in summer or warm in winter. The Prius Prime doesn’t offer rear air conditioning vents, only heat vents.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the Volvo S90 has a standard wireless phone charging system (Qi) in the center console. Only the Prius Prime XSE offers wireless charging.
