The K900 comes with a full 5-year/60,000-mile basic warranty, which covers the entire car and includes 24-hour roadside assistance. The S90’s 4-year/50,000-mile basic warranty expires 1 year and 10,000 miles sooner.

Kia’s powertrain warranty covers the K900 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 almost 3 times as many Kia dealers as there are Volvo dealers, which makes it much easier should you ever need service under the K900’s warranty.

To lower fuel costs and make buying fuel easier, the Kia K900 uses regular unleaded gasoline (premium recommended for maximum performance). The S90 requires premium, which can cost 20 to 55 cents more per gallon.

The K900 has 7.1 gallons more fuel capacity than the S90 T8 Plug-In Hybrid’s standard fuel tank (20.3 vs. 13.2 gallons), for longer range between fill-ups. The K900 has 4.4 gallons more fuel capacity than the S90 T6’s standard fuel tank (20.3 vs. 15.9 gallons).

For better traction and acceleration, the K900 has larger rear tires than the S90 (275/40R19 vs. 245/45R18). The K900’s rear tires are larger than the largest rear tires available on the S90 (275/40R19 vs. 255/35R20).

The K900’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 K900 has standard 19-inch wheels. Smaller 18-inch wheels are standard on the S90.

The front and rear suspension of the K900 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 K900’s wheelbase is 1.7 inches longer than on the S90 (122.2 inches vs. 120.5 inches).

The K900 executes Motor Trend’s “Figure Eight” maneuver quicker than the S90 T6 Inscription (25.7 seconds @ .72 average G’s vs. 26.3 seconds @ .68 average G’s).

The design of the Kia K900 amounts to more than styling. The K900 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 K900 get better fuel mileage.

The front grille of the K900 uses electronically controlled shutters to close off airflow and reduce drag when less engine cooling is needed. This helps improve highway fuel economy. The S90 doesn’t offer active grille shutters.

Because it has more passenger and cargo room, the EPA rates the K900 a Large car, while the S90 is rated a Mid-size.

The K900 has 8 cubic feet more passenger volume than the S90 (110 vs. 102).

The K900 has 3.3 inches more front headroom, 3.5 inches more front legroom, 1.5 inches more front shoulder room, .2 inches more rear headroom and 1.8 inches more rear shoulder room than the S90.

For enhanced passenger comfort on long trips the K900’s available rear seats recline. The S90’s rear seats don’t recline.

The engine in the K900 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 K900 to save the owner time and money by calculating maintenance intervals 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.

The K900’s standard easy entry system 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 K900 has standard extendable sun visors. The S90 doesn’t offer extendable visors.

The K900 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.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the Kia K900 has a standard wireless phone charging system (Qi) in the center console and for the rear passengers. The S90 doesn’t offer wireless personal charging.
