Safety

The XT6’s optional pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Sorento doesn’t offer pre-crash pretensioners.

In the past twenty years hundreds of infants and young children have died after being left in vehicles, usually by accident. When turning the vehicle off, drivers of the XT6 are reminded to check the back seat if they opened the rear door before starting out. The Sorento doesn’t offer a back seat reminder.

Over 200 people are killed each year when backed over by motor vehicles. The XT6 offers optional Reverse Automatic Braking that uses rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The Sorento doesn’t offer backup collision prevention brakes.

A passive infrared night vision system optional on the XT6 helps the driver to more easily detect people, animals or other objects in front of the vehicle at night. Using an infrared camera to detect heat, the system then displays the image on a monitor in the dashboard. The Sorento doesn’t offer a night vision system.

The XT6 has standard OnStar®, which uses a global positioning satellite (GPS) receiver and a cellular system to get turn-by-turn driving directions, remotely unlock your doors if you lock your keys in, help track down your vehicle if it’s stolen 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 XT6 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, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, rearview cameras, available all wheel drive and around view monitors.

Warranty

The XT6’s corrosion warranty is 1 year and unlimited miles longer than the Sorento’s (6/unlimited vs. 5/100,000).

There are over 16 percent more Cadillac dealers than there are Kia dealers, which makes it easier should you ever need service under the XT6’s warranty.

Engine

The XT6’s 3.6 DOHC V6 produces 125 more horsepower (310 vs. 185) and 93 lbs.-ft. more torque (271 vs. 178) than the Sorento’s standard 2.4 DOHC 4-cyl. The XT6’s 3.6 DOHC V6 produces 20 more horsepower (310 vs. 290) and 19 lbs.-ft. more torque (271 vs. 252) than the Sorento’s optional 3.3 DOHC V6.

Fuel Economy and Range

An engine control system that can shut down half of the engine’s cylinders helps improve the XT6’s fuel efficiency. The Sorento doesn’t offer a system that can shut down part of the engine.

In heavy traffic or at stoplights the XT6’s engine automatically turns off when the vehicle is stopped, saving fuel and reducing pollution. The engine is automatically restarted when the driver gets ready to move again. (Start/Stop isn’t accounted in present EPA fuel mileage tests.) The Sorento doesn’t offer an automatic engine start/stop system.

The XT6 AWD’s standard fuel tank has 3.2 gallons more fuel capacity than the Sorento (22 vs. 18.8 gallons).

The XT6 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.

Transmission

A nine-speed automatic is standard on the Cadillac XT6, for better acceleration and lower engine speed on the highway. Only an eight-speed automatic is available for the Sorento.

Brakes and Stopping

The XT6’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

For better traction, the XT6Sport’s optional tires are larger than the largest tires available on the Sorento (265/45R21 vs. 235/65R17).

The XT6’s standard tires provide better handling because they have a lower 55 series profile (height to width ratio) that provides a stiffer sidewall than the Sorento L/LX’s standard 65 series tires. The XT6Sport’s optional tires have a lower 45 series profile than the Sorento SX/SXL’s 55 series tires.

For better ride, handling and brake cooling the XT6 has standard 20-inch wheels. Smaller 17-inch wheels are standard on the Sorento L/LX. The XT6Sport’s optional 21-inch wheels are larger than the 19-inch wheels on the Sorento SX/SXL.

The Cadillac XT6’s wheels have 6 lugs for longer wheel bearing life, less chance of rotor warping and greater strength. The Kia Sorento only has 5 wheel lugs per wheel.

Suspension and Handling

The XT6 offers an optional driver-adjustable suspension system. It allows the driver to choose between an extra-supple ride, reducing fatigue on long trips, or a sport setting, which allows maximum control for tricky roads or off-road. The Sorento’s suspension doesn’t offer adjustable shock absorbers.

For a smoother ride and more stable handling, the XT6’s wheelbase is 3.3 inches longer than on the Sorento (112.7 inches vs. 109.4 inches).

For better handling and stability, the track (width between the wheels) on the XT6 is 2.2 inches wider in the front and 1.6 inches wider in the rear than the average track on the Sorento.

Chassis

The XT6 uses computer-generated active noise cancellation to help remove annoying noise and vibration from the passenger compartment, especially at low frequencies. The Sorento doesn’t offer active noise cancellation.

Passenger Space

The XT6 has .3 inches more front headroom, .9 inches more third row headroom and .7 inches more third row shoulder room than the Sorento.

Cargo Capacity

The XT6’s cargo area provides more volume than the Sorento.

Servicing Ease

J.D. Power and Associates surveys of service recipients show that Cadillac service is better than Kia. J.D. Power ranks Cadillac third in service department satisfaction. With a 55% lower rating, Kia is ranked 20th.

Ergonomics

The XT6 offers an optional heads-up display that projects speed and other key instrumentation readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The Sorento doesn’t offer a heads-up display.

The XT6’s front and rear power windows all open fully with one touch of the switches and its front windows also automatically close, 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.

On a hot day the XT6’s driver can lower all the windows from a distance using the keyless remote. The driver of the Sorento can only operate the windows from inside the vehicle, with the ignition on.

The XT6’s rain-sensitive wipers adjust their speed and turn on and off automatically based on the amount of rainfall on the windshield. This allows the driver to concentrate on driving without constantly adjusting the wipers. The Sorento’s standard manually variable intermittent wipers have to be constantly adjusted.

The XT6’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 XT6 has standard automatic dimming rear and side view mirrors which automatically darken quickly when headlights shine on them, keeping following vehicles from blinding or distracting the driver. The Sorento offers an automatic rear view mirror, but its side mirrors don’t dim.

The XT6 has a standard heated steering wheel to take the chill out of steering on extremely cold winter days before the vehicle heater warms up. A heated steering wheel costs extra on the Sorento.

The XT6 has a standard dual zone air conditioning allows the driver and front passenger to choose two completely different temperatures so people with different temperature preferences won’t have to compromise. This makes both the driver and front passenger as comfortable as possible. Dual zone air conditioning costs extra on the Sorento and isn’t available on the Sorento L.

The XT6’s standard automatic temperature control maintains the temperature you set, automatically controlling fan speed, vents and temperature to maintain a consistent, comfortable environment. The Sorento L doesn’t offer automatic air conditioning.

The XT6’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 XT6’s optional Automatic Park Assist can parallel park or back into a parking spot by itself, starting and stopping automatically, with the driver only responsible for switching from reverse to drive. The Sorento doesn’t offer an automated parking system.
