Compare the2023 Toyota HighlanderVS 2023 Mercedes GLS

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 Highlander are reminded to check the back seat if they opened the rear door before starting out. The GLS doesn’t offer a back seat reminder.

Over 200 people are killed each year when backed over by motor vehicles. The Highlander Limited/Platinum has a standard Parking Support Brake that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The GLS doesn’t offer automatic braking for stationary objects directly to the rear.

The Highlander’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 Highlander and the GLS have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front and rear 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, rearview cameras, driver alert monitors, available all wheel drive, blind spot warning systems, around view monitors and rear cross-path warning.

For its performance in IIHS driver-side and passenger-side small overlap frontal, moderate overlap frontal, updated side impact, headlight, daytime pedestrian crash prevention, and nighttime pedestrian crash prevention testing, the Insurance Institute for Highway Safety grants the Highlander its highest rating: “Top Safety Pick Plus” for 2023, a rating granted to only 29 vehicles tested by the IIHS. The GLS has not been tested, yet.

Toyota’s powertrain warranty covers the Highlander 1 year and 10,000 miles longer than Mercedes covers the GLS. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 5 years or 60,000 miles. Coverage on the GLS ends after only 4 years or 50,000 miles.

Toyota pays for scheduled maintenance on the Highlander for 2 years and 25000 miles. Toyota will pay for oil changes, lubrication and any other required maintenance. Mercedes doesn’t pay scheduled maintenance for the GLS.

There are over 3 times as many Toyota dealers as there are Mercedes dealers, which makes it much easier should you ever need service under the Highlander’s warranty.

On the EPA test cycle the Highlander gets better mileage than the GLS:

To lower fuel costs and make buying fuel easier, the Toyota Highlander uses regular unleaded gasoline. The GLS requires premium, which can cost 20 to 55 cents more per gallon.

For better maneuverability, the Highlander’s turning circle is 2 feet tighter than the GLS’ (37.4 feet vs. 39.4 feet).

The Toyota Highlander may be more efficient, handle and accelerate better because it weighs about 1300 to 1650 pounds less than the Mercedes GLS.

The Highlander is 10 inches shorter than the GLS 450, making the Highlander easier to handle, maneuver and park in tight spaces.

The Highlander has standard seating for 8 passengers; the GLS can only carry 7.

The Highlander has 1.8 inches more front headroom and 1.7 inches more front legroom than the GLS.

For enhanced passenger comfort on long trips the Highlander’s middle and third row seats recline. The GLS’ third row seats don’t recline.

The Highlander’s cargo area provides more volume than the GLS.

A Trailer Sway Control (TSC) is standard on the Highlander, using the Enhanced Vehicle Stability Control sensors to detect trailer sway, then uses individual brakes to counteract any swaying and help keep the tow vehicle and trailer steady. A trailer sway program costs extra on the GLS.

To improve rear visibility by keeping the rear window clear, the Highlander 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.

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

Consumer Reports® recommends the Toyota Highlander, based on reliability, safety and performance. The Mercedes GLS isn't recommended.
