The 2026 Acura ADX is engineered around a 1.5L I4 engine that works in tandem with a Continuously Variable Transmission (CVT). This powertrain is designed to provide consistent response, especially in the A-Spec Package, which utilizes a FWD drivetrain to maximize its efficiency. In comparison, the 2026 Mercedes-Benz GLA 250 SUV employs a 2.0L Inline-4 turbo with mild hybrid drive. This engine generates 221 hp @ 5,500 rpm and 258 lb-ft @ 1,800-4,000 rpm. For drivers seeking more aggressive output, the AMG GLA 35 SUV features an AMG-enhanced 2.0L inline-4 turbo with hybrid assist, delivering 302 hp @ 5,800 rpm and 295 lb-ft @ 3,000-4,000 rpm through an AMG SPEEDSHIFT DCT 8-speed dual-clutch.
The GLA features a larger turbocharged engine with mild-hybrid technology and a dual-clutch transmission compared to the ADX's CVT.

The Mercedes-Benz GLA SUV focuses on a tighter urban aesthetic. The GLA 250 SUV comes standard with 18-inch twin 5-spoke wheels and 235/55R18 tires, while the AMG GLA 35 SUV features standard AMG body styling and 19-inch AMG twin 5-spoke wheels. While the Mercedes-Benz GLA SUV is designed for agility in tight spaces, the larger exterior dimensions of the Acura ADX provide a more versatile platform for those who prioritize a commanding silhouette and greater physical scale in their luxury crossover.
The 2026 Acura ADX and 2026 Mercedes-Benz GLA SUV both provide refined 5-passenger seating, but they approach cabin utility with different philosophies. Inside the Acura ADX Base, owners can tailor their comfort with a $525 Heated Steering Wheel and ensure privacy for their belongings with a $185 Cargo Cover. Moving to the A-Spec Package, the interior takes on a more athletic character, offering a $525 Sport Steering Wheel with Heating Function to match its performance-oriented mission. Acura also emphasizes protection and longevity through specific accessories like the $205 All-Season Floor Mats and a $265 Pet Rear Cabin Liner, ensuring the cabin remains pristine during daily use.

The Mercedes-Benz GLA SUV counters with standard power front seats with 3-position memory and MB-Tex upholstery in the GLA 250 SUV. While the Mercedes-Benz provides about 50.5 cu ft of cargo space, the Acura ADX provides more granular organization options, such as a $90 Cargo Organizer and $115 Seat Back Protectors. The AMG GLA 35 SUV elevates the experience with standard heated power front seats and an illuminated entry system, though many premium features remain tied to tiered bundles. For instance, the GLA requires the $450 Winter Package to gain a heated steering wheel and heated windshield washers, whereas Acura offers these comfort upgrades as specific, accessible additions.
Utility is further refined in the Acura ADX through the available Cargo Protection Package, which includes a $165 Cargo Tray to manage gear more effectively than a standard flat floor. While the GLA 250 SUV includes 40/20/40-split folding and reclining rear seats for flexibility, the Acura ADX focuses on long-term durability with its various All-Season Protection Packages. This emphasis on individual comfort and resilient luxury materials makes the Acura ADX a more adaptable choice for those who demand both style and substance in their daily driver.
The GLA features larger standard screens and a digital key, while the ADX includes wireless charging and 5G Wi-Fi as standard across the line.

The digital landscape of the luxury crossover segment is defined by how seamlessly a vehicle integrates into the owner's digital life. In the 2026 Acura ADX, drivers are greeted by a 10.2-inch Acura Precision Cockpit digital instrument cluster, a high-resolution interface that compares closely with the 10.25-inch display found in the 2026 Mercedes-Benz GLA SUV. While the GLA features a 10.25-inch touchscreen multimedia display compared to the 9-inch color touchscreen in the ADX, the Acura system emphasizes ergonomic reach and rapid response times.
Connectivity remains a standard priority for both manufacturers, as the ADX and the GLA provide Wireless Apple CarPlay and Wireless Android Auto across their respective lineups. Acura enhances the user experience by embedding Google Assistant and Alexa built-in, allowing for a familiar voice-command interface. The GLA utilizes the Mercedes-Benz User Experience (MBUX) with Natural Language Understanding. For those selecting the A-spec w/Advance Package, the ADX provides Google Maps built-in for precise navigation, while the GLA offers MB Navigation as an available feature.
Audio performance is a standout characteristic for the Acura ADX. The A-spec w/Advance Package comes equipped with a Bang & Olufsen 15-speaker premium audio system, delivering an immersive experience that challenges the optional Burmester 12-speaker 710W system found in the GLA. Device management is handled via a standard 15W Qi-compatible wireless phone charging pad in the ADX, which mirrors the standard inductive wireless charging and NFC pairing in the GLA. Both vehicles support over-the-air updates to maintain system peak performance; the ADX uses standard 5G telematics and includes a standard 5G capability Wi-Fi hotspot, whereas the GLA relies on the Mercedes me connect service. While the GLA offers an available head-up display, the ADX A-spec w/Advance Package includes a standard surround-view camera to simplify low-speed maneuvering. This robust suite of technology ensures the Acura ADX remains a formidable contender for the tech-focused driver.
The GLA offers a comprehensive list of standard and optional safety technologies, including specialized features like Crosswind Assist.
| Specification | 2026 Acura ADX | 2026 Mercedes-Benz GLA SUV |
|---|---|---|
| Advanced Driver Assistance Suite | Standard | Standard |
| Blind Spot Monitoring | Blind Spot Information System (BSI) | Standard |
| Active Brake Assist | Collision Mitigation Braking System (CMBS™) | Standard |
| Driver Attention Monitor | Standard (part of AcuraWatch®) | Standard (ATTENTION ASSIST) |
| Adaptive Cruise Control | Available (part of AcuraWatch®) | Available (DISTRONIC) |
| Lane Keeping Assist | Available | Available |

| Crosswind Assist | Not Available | Standard |
Both the 2026 Acura ADX and the 2026 Mercedes-Benz GLA SUV integrate sophisticated protective systems, though their approach to standard equipment differs significantly. The Acura ADX includes its Advanced Driver Assistance Suite as standard across all trims, including the $38,350 Base model. This ensures that every driver benefits from a unified protective layer without needing to navigate complex options. Conversely, the Mercedes-Benz GLA 250 SUV starts at a higher $41,500 and, while it includes a standard Advanced Driver Assistance Suite, many specific features remain optional.
The Mercedes-Benz GLA SUV comes standard with Blind Spot Monitoring, Active Brake Assist, and the ATTENTION ASSIST driver attention monitor. It also includes standard Crosswind Assist to maintain stability in high-wind conditions. However, advanced systems such as DISTRONIC adaptive cruise control, Active Lane Keeping Assist, and Traffic Sign Recognition are listed as Available rather than standard. To equip the GLA 250 SUV with these features, buyers typically must add the $1,700 Driver Assistance Package, which also provides Active Speed Limit Assist and PRE-SAFE PLUS.
The Acura ADX maintains a value advantage by providing its core safety suite as standard even on the $41,484 A-Spec Package. While the performance-oriented AMG GLA 35 SUV features 7 air bags and a standard 4-wheel Electronic Traction System (4-ETS), it still lists rear-seat side-impact air bags as an optional addition. By standardizing its primary safety technologies, the Acura ADX offers a more predictable and accessible safety profile for luxury crossover buyers compared to the tiered availability and higher entry costs of the Mercedes-Benz lineup.
The financial landscape of the compact luxury segment favors the 2026 Acura ADX, which presents a lower barrier to entry across its entire lineup. Efficiency plays a critical role in long-term ownership costs; for example, the Acura ADX A-Spec Package achieves an EPA-estimated 30 combined MPG, outperforming the AMG GLA 35 SUV, which is rated at 22 city and 30 highway MPG. While the GLA 250 SUV offers 34 highway MPG, its higher initial cost may take years to offset through fuel savings alone. Furthermore, the ADX provides tailored protection through dealer-installed options like the All-Season Protection Package I for $570 or the Cargo Protection Package for $485. These additions help preserve the vehicle's condition, ensuring the Acura ADX remains a fiscally responsible choice for discerning luxury buyers.
The Acura ADX starts at a lower entry price, while the Mercedes-Benz GLA offers a high-performance AMG variant at the top of its range.
| 2026 Acura ADX Trim | MSRP | 2026 Mercedes-Benz GLA SUV Trim | MSRP |
|---|---|---|---|
| Base | $38,350 | GLA 250 SUV | $41,500 |
| A-Spec Package | $41,484 | GLA 250 4MATIC SUV | $43,500 |
| A-spec w/Advance Package | $46,450 | AMG GLA 35 SUV | $58,550 |
Value differences become apparent when comparing mid-tier options. For $3,134 more than the A-Spec Package, the A-spec w/Advance Package adds premium features while still remaining $12,100 less than the performance-focused Mercedes-Benz AMG variant. This pricing strategy positions the Acura ADX as the more accessible premium crossover without sacrificing the sophisticated features expected in this class.
