Compare the2022 Mercedes CLSVS 2022 Volvo S90

The Mercedes CLS has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags helps prevent the driver and front passenger from sliding under their seatbelts or the main frontal airbags; this keeps them better positioned during a collision for maximum protection. Knee airbags also help keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The S90 doesn’t offer a front passenger side knee airbag.

Both the CLS and the S90 have standard driver and passenger frontal airbags, front side-impact airbags, driver knee 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, daytime running lights, blind spot warning systems, rearview cameras, driver alert monitors, available all wheel drive, lane departure warning systems, around view monitors and rear cross-path warning.

There are over 36 percent more Mercedes dealers than there are Volvo dealers, which makes it easier should you ever need service under the CLS’ warranty.

J.D. Power and Associates’ 2021 Initial Quality Study of new car owners surveyed provide the statistics that show that Mercedes vehicles are better in initial quality than Volvo vehicles. J.D. Power ranks Mercedes 25th in initial quality. With 17 more problems per 100 vehicles, Volvo is ranked 29th.

J.D. Power and Associates’ 2021 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Mercedes vehicles are more reliable than Volvo vehicles. J.D. Power ranks Mercedes 15th in reliability. With 21 more problems per 100 vehicles, Volvo is ranked 25th.

The CLS’ 3.0 turbo 6-cylinder hybrid produces 46 more horsepower (362 vs. 316) and 74 lbs.-ft. more torque (369 vs. 295) than the S90 B6’s standard 2.0 turbo/supercharged 4-cylinder hybrid.

As tested in Car and Driver the Mercedes CLS is faster than the S90 B6 2.0 turbo/supercharged 4-cylinder:

Both the CLS and the S90 have a standard automatic start/stop engine feature to stop unnecessary fuel waste and pollution at stop lights and heavy traffic. All CLSs have a standard disable switch for the system, so a driver can keep the engine from shutting off when the vehicle stops temporarily. A disable switch costs extra on the S90.

The CLS has 5.2 gallons more fuel capacity than the S90 (21.1 vs. 15.9 gallons), for longer range between fill-ups.

A nine-speed automatic is standard on the Mercedes CLS, for better acceleration and lower engine speed on the highway. Only an eight-speed automatic is available for the S90.

For better stopping power the CLS’ brake rotors are larger than those on the S90:

For better traction and acceleration, the CLS has larger rear tires than the S90 (275/35R19 vs. 245/45R18). The CLS’ rear tires are larger than the largest rear tires available on the S90 (275/35R19 vs. 255/35R20).

The CLS’ standard 245/40R19 front and 275/35R19 rear tires provide better handling because they have a lower 40 series front and 35 series rear profile (height to width ratio) that provides a stiffer sidewall than the S90’s standard 45 series tires. The CLS’ optional 275/30R20 rear tires have a lower 30 series profile than the S90’s optional 35 series tires.

For better ride, handling and brake cooling the CLS has standard 19-inch wheels. Smaller 18-inch wheels are standard on the S90.

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires standard on the CLS 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 CLS 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 CLS has a standard automatic front and rear load leveling suspension to keep ride height level with a heavy load or when towing. The CLS’ 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 S90 doesn’t offer a load leveling suspension.

The CLS’ 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.

The CLS 450 4MATIC handles at .93 G’s, while the S90 T6 Momentum pulls only .90 G’s of cornering force in a Car and Driver skidpad test.

The CLS 450 4MATIC executes Motor Trend’s “Figure Eight” maneuver quicker than the S90 T6 Inscription (25.8 seconds @ .72 average G’s vs. 26.3 seconds @ .68 average G’s).

The CLS is 3.7 inches shorter than the S90, making the CLS easier to handle, maneuver and park in tight spaces.

The design of the Mercedes CLS amounts to more than styling. The CLS has an aerodynamic coefficient of drag of .27 Cd. 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 CLS get better fuel mileage.

The CLS has .3 inches more front shoulder room and 1.1 inches more rear shoulder room than the S90.

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

The engine in the CLS 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.

An ASSYST PLUS is standard on the CLS to save the owner time and money by calculating maintenance intervals for oil changes 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 Mercedes service is better than Volvo. J.D. Power ranks Mercedes 6th in service department satisfaction (above the industry average). With a 4% lower rating, Volvo is ranked 11th.

The CLS’ standard easy entry system raises the steering wheel, making it easier for the driver to get in and out. The S90 doesn’t offer an easy entry system.

Heated windshield washer fluid is standard on the CLS to defrost the washer nozzles and quickly clear ice and frost from the windshield without scraping. The S90 doesn’t offer heated windshield washer fluid. Its optional heated washer nozzles will defrost the washer fluid but not the windshield.

The CLS’ optional Active Parking Assist can parallel park or back into a parking spot by itself, starting, stopping and changing direction automatically. The S90 doesn’t offer an automated parking system.

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

The CLS will cost the buyer less in the long run because of its superior resale value. The IntelliChoice estimates that the CLS will retain 40.26% to 41.01% of its original price after five years, while the S90 only retains 38.82% to 38.97%.

The Mercedes E-Class/CLS outsold the Volvo 90 Series by almost 14 to one during the 2021 model year.
