Safety

Both the G90 and the S90 have standard driver and passenger frontal airbags, front and rear 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, lane departure warning systems, blind spot warning systems, rearview cameras, rear cross-path warning, driver alert monitors and available all wheel drive.

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 “Good” rating, the Insurance Institute for Highway Safety grants the G90 its highest rating: “Top Pick Plus” for 2018, a rating granted to only 28 vehicles tested by the IIHS. The S90 was last qualified as only a “Top Pick” in 2017.

Warranty

The G90 comes with a full 5-year/60,000-mile basic warranty, which covers the entire car and includes free 24-hour roadside assistance. The S90’s 4-year/50,000-mile basic warranty expires 1 year and 10,000 miles sooner.

Genesis’ powertrain warranty covers the G90 6 years and 50,000 miles longer than Volvo covers the S90. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 10 years or 100,000 miles. Coverage on the S90 ends after only 4 years or 50,000 miles.

There are over 18 percent more Genesis dealers than there are Volvo dealers, which makes it easier should you ever need service under the G90’s warranty.

Reliability

To reliably start during all conditions and help handle large electrical loads, the G90 has a standard 950-amp battery. The S90’s 800-amp battery isn’t as powerful.

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 G90’s reliability 20 points higher than the S90.

J.D. Power and Associates rated the G90 first among large premium cars in their 2018 Initial Quality Study. The S90 isn’t in the top three in its category.

J.D. Power and Associates’ 2018 Initial Quality Study of new car owners surveyed provide the statistics that show that Genesis vehicles are better in initial quality than Volvo vehicles. J.D. Power ranks Genesis first in initial quality, above the industry average. With 54 more problems per 100 vehicles, Volvo is ranked 29th, below the industry average.

Fuel Economy and Range

To lower fuel costs and make buying fuel easier, the Genesis G90 uses regular unleaded gasoline (premium recommended for maximum performance). The S90 T5 requires premium, which can cost 20 to 55 cents more per gallon.

The G90 has 8.7 gallons more fuel capacity than the S90 T8 Plug-In Hybrid’s standard fuel tank (21.9 vs. 13.2 gallons), for longer range between fill-ups. The G90 has 6 gallons more fuel capacity than the S90 T6’s standard fuel tank (21.9 vs. 15.9 gallons).

Brakes and Stopping

For better stopping power the G90’s brake rotors are larger than those on the S90:

Tires and Wheels

For better traction and acceleration, the G90 has larger rear tires than the S90 (275/40R19 vs. 245/45R18). The G90’s rear tires are larger than the largest rear tires available on the S90 (275/40R19 vs. 255/35R20).

The G90’s 275/40R19 rear tires provide better handling because they have a lower 40 series profile (height to width ratio) that provides a stiffer sidewall than the S90’s standard 45 series tires.

For better ride, handling and brake cooling the G90 has standard 19-inch wheels. Smaller 18-inch wheels are standard on the S90.

Suspension and Handling

The G90 has standard front and rear gas-charged shocks for better control over choppy roads. The S90’s suspension doesn’t offer gas-charged shocks.

The front and rear suspension of the G90 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.

For a smoother ride and more stable handling, the G90’s wheelbase is 3.9 inches longer than on the S90 (124.4 inches vs. 120.5 inches).

Chassis

The design of the Genesis G90 amounts to more than styling. The G90 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 G90 get better fuel mileage.

Passenger Space

Because it has more passenger and cargo room, the EPA rates the G90 a Large car, while the S90 is rated a Mid-size.

The G90 has 11.2 cubic feet more passenger volume than the S90 (113.2 vs. 102).

The G90 has 3.3 inches more front headroom, 4.1 inches more front legroom, .1 inches more front hip room, 1.6 inches more front shoulder room, .2 inches more rear headroom, .1 inches more rear hip room and 2.5 inches more rear shoulder room than the S90.

For enhanced passenger comfort on long trips the G90 5.0’s rear seats recline. The S90’s rear seats don’t recline.

Cargo Capacity

The G90 has a much larger trunk than the S90 (15.7 vs. 13.5 cubic feet).

Servicing Ease

The engine in the G90 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.

Ergonomics

The Insurance Institute for Highway Safety (IIHS) conducts detailed tests on headlights for their range both straight ahead and in curves and to be certain they don’t exceed acceptable amounts of glare to oncoming drivers. The G90’s available headlights were rated “Acceptable” by the IIHS, while the S90’s headlights are rated “Marginal” to “Poor.”

To shield the driver and front passenger’s vision over a larger portion of the windshield and side windows, the G90 has standard extendable sun visors. The S90 doesn’t offer extendable visors.

The G90 has a standard heated steering wheel to take the chill out of steering on extremely cold winter days before the car heater warms up. A heated steering wheel costs extra on the S90.

Recommendations

Consumer Reports® recommends the Genesis G90, based on reliability, safety and performance. The Volvo S90 isn't recommended.
