J.D. Power and Associates’ 2023 Initial Quality Study of new car owners surveyed provide the statistics that show that Infiniti vehicles are better in initial quality than Volvo vehicles. With 38 fewer problems per 100 vehicles, JD Power ranks Infiniti higher than Volvo.

J.D. Power and Associates’ 2022 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Infiniti vehicles are more reliable than Volvo With 28 fewer problems per 100 vehicles in the first three years of ownership, J.D. Power ranks Infiniti higher than Volvo.

From surveys of all its subscribers, Consumer Reports’ January 2024 Auto Issue reports that Infiniti vehicles are more reliable than Volvo vehicles. Consumer Reports ranks Infiniti 12 places higher in reliability than Volvo.

The Q50’s standard 3.0 turbo V6 produces 5 more horsepower (300 vs. 295) than the S90 B6’s standard 2.0 turbo/supercharged 4-cylinder hybrid.

As tested in Consumer Reports the Infiniti Q50 3.0 is faster than the S90 B6 2.0 turbo/supercharged 4-cylinder:

The Q50 has 4.1 gallons more fuel capacity than the S90 (20 vs. 15.9 gallons), for longer range between fill-ups.

For better stopping power the Q50 Red Sport 400’s front brake rotors are larger than those on the S90:

The Q50 stops shorter than the S90:

The Q50 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 S90 doesn’t offer vehicle monitored tire inflation.

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires standard on the Q50 can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. The S90 doesn’t offer run-flat tires.

The front and rear suspension of the Q50 uses coil springs for better ride, handling and control than the S90, which uses transverse leafs springs in the rear. Coil springs compress more progressively and offer more suspension travel for a smoother ride with less bottoming out.

The Q50 Sport’s optional drift compensation steering can automatically compensate for road conditions which would cause the vehicle to drift from side to side, helping the driver to keep the vehicle straight more easily. The S90 doesn’t offer drift compensation steering.

For better maneuverability, the Q50’s turning circle is 2 feet tighter than the S90’s (36.7 feet vs. 38.7 feet). The Q50 AWD’s turning circle is 1.3 feet tighter than the S90’s (37.4 feet vs. 38.7 feet).

The Infiniti Q50 may be more efficient, handle and accelerate better because it weighs about 500 to 650 pounds less than the Volvo S90.

The Q50 is 10.5 inches shorter than the S90, making the Q50 easier to handle, maneuver and park in tight spaces.

The design of the Infiniti Q50 amounts to more than styling. The Q50 offers aerodynamic coefficients of drag from .26 to .29 Cd (depending on bodystyle and options). That is lower than the S90 (.28 to .33) and many sports cars. A more efficient exterior helps keep the interior quieter and helps the Q50 get better fuel mileage.

The Q50 has 1.7 inches more front headroom, 2.3 inches more front legroom and .7 inches more rear shoulder room than the S90.

The Q50’s standard rear seats fold to accommodate long and bulky cargo. The S90 Luxury Package doesn’t offer folding rear seats.

The engine in the Q50 is mounted longitudinally (North-South), instead of sideways, as in the S90. This makes it easier to service and maintain, because the accessory belts are in front.

A maintenance reminder system is standard on the Q50 to save the owner time and money by calculating maintenance intervals for oil changes and tire rotation based on odometer mileage. This takes the guesswork out of keeping your vehicle in top condition and helps it last longer. Volvo doesn’t offer a maintenance reminder on the S90.

J.D. Power and Associates surveys of service recipients show that Infiniti service is better than Volvo. J.D. Power ranks Infiniti 9th in service department satisfaction (above the industry average). With an 8% lower rating, Volvo is ranked 12th.

The Q50’s standard Entry/Exit Assist raises the steering wheel and glides the driver’s seat back, making it easier for the driver to get in and out. The S90 doesn’t offer an easy entry system.

To shield the driver and front passenger’s vision over a larger portion of the windshield and side windows, the Q50 has standard extendable sun visors. The S90 doesn’t offer extendable visors.

The Q50 is available in both rear-wheel drive and all-wheel drive configurations. The S90 doesn’t offer a two-wheel drive configuration.

Consumer Reports® recommends the Infiniti Q50, based on reliability, safety and performance. The Volvo S90 isn't recommended.
