Safety Comparison

The middle row seatbelts optional on the Flex inflate when a collision is detected, helping to spread crash forces over a much larger area of the body and limiting head and neck movement. This can help prevent spinal and internal injuries. The Sorento doesn’t offer inflatable seatbelts.

The Flex has standard 911 Assist, which uses a global positioning satellite (GPS) receiver and a cellular system to get turn-by-turn driving directions or send emergency personnel to the scene if any airbags deploy. The Sorento doesn’t offer a GPS response system, only a navigation computer with no live response for emergencies, so if you’re involved in an accident and you’re incapacitated help may not come as quickly.

Both the Flex and the Sorento have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, front-wheel drive, height-adjustable front shoulder belts, plastic fuel tanks, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, available collision warning systems, blind spot warning systems and rear cross-path warning.

Warranty Comparison

The Flex’s 5 year corrosion warranty has no mileage limitations, but the corrosion warranty on the Sorento runs out after 100,000 miles.

There are over 5 times as many Ford dealers as there are Kia dealers, which makes it much easier should you ever need service under the Flex’s warranty.

Fuel Economy and Range Comparison

The Flex 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 Sorento doesn’t offer a cap-less fueling system.

Brakes and Stopping Comparison

For better stopping power the Flex’s brake rotors are larger than those on the Sorento:

 

Flex

Sorento

Front Rotors

12.8 inches

12.6 inches

Rear Rotors

13 inches

12.1 inches

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

Tires and Wheels Comparison

For better traction, the Flex’s optional tires are larger than the largest tires available on the Sorento (255/45R20 vs. 235/65R17).

The Flex SEL’s standard tires provide better handling because they have a lower 60 series profile (height to width ratio) that provides a stiffer sidewall than the Sorento L/LX’s standard 65 series tires. The Flex’s optional tires have a lower 45 series profile than the Sorento SX/Limited’s 55 series tires.

For better ride, handling and brake cooling the Flex offers optional 20-inch wheels. The Sorento’s largest wheels are only 19-inches.

Suspension and Handling Comparison

The Flex’s 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 Sorento doesn’t offer drift compensation steering.

For a smoother ride and more stable handling, the Flex’s wheelbase is 8.5 inches longer than on the Sorento (117.9 inches vs. 109.4 inches).

For better handling and stability, the track (width between the wheels) on the Flex is 1.2 inches wider in the front and .8 inches wider in the rear than the average track on the Sorento.

Passenger Space Comparison

The Flex has 2.3 inches more front headroom, 1.2 inches more rear headroom, 4.9 inches more rear legroom, .1 inches more rear shoulder room, 2.4 inches more third row headroom and 1.6 inches more third row legroom than the Sorento.

The Flex Limited offers an optional rear tailgate seat that can be flipped rearward and used for tailgate picnics. (Do not use seat reversed while vehicle in motion.) The Sorento doesn’t offer a rear tailgate seat.

Cargo Capacity Comparison

The Flex’s cargo area provides more volume than the Sorento.

The Flex’s cargo area is larger than the Sorento’s in almost every dimension:

16.5”/47”/83.3”

14.7”/44.7”/78”

Pressing a switch automatically lowers the Flex’s second and third row seats, to make changing between passengers and cargo easier. The Sorento doesn’t offer automatic folding seats.

Ergonomics Comparison

The Flex’s front power windows open or close fully with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside the car. The Sorento’s standard passenger windows don’t open or close automatically.

In case you lock your keys in your vehicle, or don’t have them with you, you can let yourself in using the Flex’s exterior PIN entry system. The Sorento doesn’t offer an exterior PIN entry system.

The Flex SE/SEL’s standard speed-sensitive wipers speed up when the vehicle does, so that the driver doesn’t have to continually adjust the speed of the wipers. The Sorento’s manually variable intermittent wipers have to be constantly adjusted. The Flex Limited’s standard wipers adjust their speed and turn on and off automatically according to the amount of rainfall on the windshield.

The Flex has a standard automatic headlight on/off feature. When the ignition is on, the headlights automatically turn on at dusk and off after dawn. When the ignition turns off, the headlights turn off after a delay timed to allow you to securely get to your front door. The Sorento only offers an automatic headlight on/off feature as an extra cost option.

The Flex’s standard side window demisters help clear frost or condensation from the side windows in the winter. The Sorento doesn’t even offer side window demisters, so the driver may have to wipe the windows from the outside to gain side vision.

The Flex (except SE)’s available GPS navigation system has a real-time traffic update feature that plots alternative routes to automatically bypass traffic problems. (Service not available in all areas.) The Sorento’s navigation system doesn’t offer real-time traffic updates.

The Flex Limited’s optional Active Park Assist can parallel park or back into a parking spot by itself, with the driver only controlling speed with the brake pedal. The Sorento doesn’t offer an automated parking system.

Economic Advantages Comparison

According to The Car Book by Jack Gillis, the Flex is less expensive to operate than the Sorento because it costs $135 less to do the manufacturer’s suggested maintenance for 50,000 miles. Typical repairs cost much less on the Flex than the Sorento, including $121 less for fuel injection, $43 less for a fuel pump, $70 less for front struts and $757 less for a timing belt/chain.
