Compare the2022 Kia TellurideVS 2022 Mercedes GLS

Both the Telluride and GLS have child safety locks to prevent children from opening the rear doors. The Telluride has power child safety locks, allowing the driver to activate and deactivate them from the driver's seat and to know when they're engaged. The GLS’ child locks have to be individually engaged at each rear door with a manual switch. The driver can’t know the status of the locks without opening the doors and checking them.

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 Telluride are reminded to check the back seat when a sensor determines the back seat is occupied. The GLS doesn’t offer a back seat reminder.

The Telluride’s standard lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane and gently nudges the vehicle back towards its lane. A lane departure warning system costs extra on the GLS.

Both the Telluride and the GLS have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front seatbelt pretensioners, height adjustable front shoulder belts, plastic fuel tanks, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, blind spot warning systems, rearview cameras, rear cross-path warning, driver alert monitors, available all wheel drive and around view monitors.

For its top level performance in IIHS driver and passenger-side small overlap frontal, moderate overlap frontal, side impact, roof strength and head restraint tests, its standard vehicle-to-vehicle front crash prevention system, its standard vehicle-to-pedestrian front crash prevention system, and its available headlight’s “Acceptable” rating, the Insurance Institute for Highway Safety grants the Telluride the rating of “Top Safety Pick” for 2022, a rating granted to only 139 vehicles tested by the IIHS. The GLS has not been tested, yet.

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

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

There are over 2 times as many Kia dealers as there are Mercedes dealers, which makes it much easier should you ever need service under the Telluride’s warranty.

For better handling and stability, the track (width between the wheels) on the Telluride is 1.5 inches wider in the front and 1 inch wider in the rear than on the GLS.

For better maneuverability, the Telluride’s turning circle is .6 feet tighter than the GLS’ (38.8 feet vs. 39.4 feet).

The Kia Telluride may be more efficient, handle and accelerate better because it weighs about 1050 to 1350 pounds less than the Mercedes GLS.

To improve rear visibility by keeping the rear window clear, the Telluride has a standard rear fixed intermittent wiper with a full on position. The rear wiper standard on the GLS only has an intermittent setting, so in a hard rain visibility isn’t as good.

Consumer Reports rated the Telluride’s headlight performance “Very Good,” a higher rating than the GLS’ headlights, which were rated “Good.”

The Telluride is available in both front-wheel drive and four-wheel drive configurations. The GLS doesn’t offer a two-wheel drive configuration.
