Mercedes wins the simple horsepower comparison, but Acura wins more of the feature-and-comfort conversation.
The 2026 Acura ADX and Mercedes-Benz GLA are both trying to win over shoppers who want a smaller luxury SUV without giving up premium features. The Mercedes-Benz GLA has the stronger power figure and a recognizable badge story. The ADX answers with a more complete feature set, stronger comfort value, and a better all-around everyday package for many buyers.
The 2026 Acura ADX is the better premium-small-SUV value for most buyers. The Mercedes-Benz GLA does offer more horsepower and a polished digital-cabin presentation, but the ADX gives you standard Google built-in, a standard panoramic moonroof, a 15-speaker premium audio system, better cargo space, and more front-seat comfort for the money.

Mercedes wins the simple horsepower comparison, but Acura wins more of the feature-and-comfort conversation.
Acura's official compare page calls out the ADX's stronger standard-equipment story here.
Acura specifically says the Lexus UX, Mercedes GLA, and Volvo XC40 do not match the ADX's cargo space.
Mercedes-Benz gives the GLA 250 a respectable power advantage. Its official model page lists 221 horsepower and 258 lb-ft of torque, which is a stronger headline than the ADX's 190 horsepower and 179 lb-ft.
The ADX still makes the better all-around ownership case. Acura uses the ADX to give shoppers the premium features they will notice every day, instead of asking them to keep climbing the options ladder. For many buyers, that is the more persuasive form of luxury value.
The GLA's digital presentation is a real strength. Mercedes highlights dual 10.25-inch displays, wireless CarPlay, and its virtual voice assistant as standard technology strengths in the current GLA 250.
The ADX counters with a smarter integrated-tech story. Acura says Google built-in is standard on the ADX A-Spec with Advance and unavailable on the GLA, while also giving the ADX a 15-speaker Bang & Olufsen system and a standard panoramic moonroof. That creates a more complete premium-feeling package without as much option logic.
Acura's compare chart makes a very strong comfort case for the ADX. It calls out standard ventilated front seats, more front legroom, and cargo space advantages over the Mercedes-Benz GLA.
Those things matter more than they may seem on a spec sheet. If you are using your premium compact SUV for commuting, errands, gym runs, weekend luggage, and occasional passengers, the ADX feels more generous and easier to live with over time.
The Mercedes-Benz GLA is still a reasonable pick for buyers who care most about the Mercedes badge and stronger output. It is stylish, modern, and clearly premium.
The ADX is the better recommendation for the buyer who wants luxury to show up in more of the places that matter every day. Better standard equipment, more comfort-forward details, and stronger practical packaging make the Acura the more convincing everyday choice.
Choose the Mercedes-Benz GLA if your top priority is stronger output and the specific Mercedes-Benz look and feel.
Choose the 2026 Acura ADX if you want the small luxury SUV that feels more complete, more comfortable, and more useful for the money. For most Westchester buyers, the ADX is the smarter recommendation.
Verdict: the 2026 Acura ADX delivers more for Westchester drivers because it turns premium-small-SUV money into stronger comfort, technology, and everyday practicality than the Mercedes-Benz GLA.
