Compare the2027 Kia Seltos VS 2026 Mercedes GLA

For enhanced safety, the front seat shoulder belts of the Kia Seltos are height-adjustable to accommodate a wide variety of driver and passenger heights. A better fit can prevent injuries and the increased comfort also encourages passengers to buckle up. The Mercedes GLA doesn’t offer height-adjustable seat belts.

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

Over 200 people are killed each year when backed over by motor vehicles. The Seltos X-Line SX offers optional Parking Collision-Avoidance Assist-Reverse that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The GLA doesn’t offer automatic braking for stationary objects directly to the rear.

The Seltos’ 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 GLA.

Both the Seltos and the GLA have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, front wheel drive, 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.

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

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

To lower fuel costs and make buying fuel easier, the Kia Seltos uses regular unleaded gasoline. The GLA requires premium, which can cost on average about 84.9 cents more per gallon.

The Seltos has a standard continuously variable transmission (CVT). With no “steps” between gears, it can keep the engine at the most efficient speed for fuel economy, or keep it at its peak horsepower indefinitely for maximum acceleration. The GLA doesn’t offer a CVT.

The Seltos offers an optional space-saver spare tire so you can replace a flat tire and drive to have the flat repaired or replaced. A spare tire isn’t available on the GLA; it requires you to depend on its run-flat tires, which limits mileage and speed before they are repaired. If a run-flat is damaged beyond repair by a road hazard your vehicle will have to be towed. Some tire options on the GLA don’t have a run-flat feature, either.

The Seltos has standard front and rear gas-charged shocks for better control over choppy roads. The GLA’s suspension doesn’t offer gas-charged shocks.

For better maneuverability, the Seltos’ turning circle is 2.2 feet tighter than the GLA’s (35.2 feet vs. 37.4 feet).

For greater off-road capability the Seltos LX has a 1.9 inches greater minimum ground clearance than the GLA (7.5 vs. 5.6 inches), allowing the Seltos to travel over rougher terrain without being stopped or damaged. The Seltos X-Line SX’s minimum ground clearance is 2.5 inches higher than on the GLA (8.1 vs. 5.6 inches).

The Kia Seltos may be more efficient, handle and accelerate better because it weighs about 200 to 500 pounds less than the Mercedes GLA.

Standard on the Seltos uses the Electronic Stability Control sensors to detect trailer sway, then uses individual brakes to counteract any swaying and help keep the tow vehicle and trailer steady. The GLA doesn’t offer electronic trailer sway control.

The Seltos’ standard Smart Key allows you to unlock the doors from either front door handle, unlock the cargo door, and start the engine, all without removing the key from pocket or purse. Keyless-Start standard on the GLA only offers hands-free access for the ignition, none to unlock the vehicle.

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

Optional air-conditioned seats in the Seltos X-Line SX keep the driver and front passenger comfortable and take the sting out of hot seats in Summer. The GLA doesn’t offer air-conditioned seats.

The Kia Seltos outsold the Mercedes GLA by over four to one during 2025.
