For years, the Mercedes-Benz GLA served as the gateway into the German automaker’s SUV universe. While the outgoing second-generation model offered strong urban appeal, buyers seeking zero-emission luxury were forced to look toward the standalone EQA.
Mercedes-Benz has officially unified its compact luxury lineup with the world premiere of the third-generation Mercedes-Benz GLA. Engineered from the ground up on the brand’s all-new Mercedes-Benz Modular Architecture (MMA), the new GLA makes history by offering its first-ever fully electric variant alongside next-generation mild-hybrid powertrains.
Featuring an impressive WLTP driving range of up to 657 km, an ultra-fast 800-volt charging architecture, and an optional triple-screen MBUX Superscreen cockpit, the new GLA sets a high benchmark for compact executive crossovers.
Decoupling the Third-Gen GLA: EV Variants & Segment Comparison
The MMA architecture allows Mercedes-Benz to maximize internal cabin space while maintaining an aerodynamic, sleek silhouette. Compared to its predecessor, the third-generation GLA grows significantly in length, width, and wheelbase, giving it a much more commanding road presence.
At launch, the electric GLA lineup spans three distinct global variants: the entry-level GLA 250, the long-range GLA 250+, and the dual-motor performance-oriented GLA 350 4MATIC.
The comparative matrix below details the technical dimensions, battery chemistry, motor outputs, and fast-charging capabilities of the new GLA EV against its key premium electric crossover competitors:

Mechanical Underpinnings: Battery Options and 800V Hyper-Charging
The headline technology inside the new GLA EV is its 800-volt electrical architecture—a high-voltage system previously reserved for flagship EVs. By doubling the operating voltage from standard 400V setups, Mercedes engineers reduced wiring weight and current heat losses while enabling extreme fast-charging speeds.
Battery Options and Range Capabilities
- 58 kWh LFP Battery (GLA 250): The entry-level model uses a lithium-iron-phosphate (LFP) cell structure. Producing 224 hp and 335 Nm of torque, it delivers a claimed WLTP range of 447 km, serving as an efficient option for daily urban commuting.
- 85 kWh NMC Battery (GLA 250+ & GLA 350): Higher trims utilize a nickel-manganese-cobalt (NMC) chemical formulation with high energy density. The single-motor GLA 250+ achieves an industry-leading 657 km WLTP range on a single charge.
- Upcoming 71 kWh Battery: Mercedes-Benz has also confirmed a mid-tier 71 kWh pack will join the global lineup to offer a balanced price-to-range sweet spot.
320 kW DC Fast Charging
Thanks to its 800V backbone, the GLA EV supports peak DC fast-charging rates of up to 320 kW. When plugged into a high-power DC station, the SUV can recover 270 km of range in just 10 minutes. For home and destination charging, an integrated 22 kW AC onboard charger comes standard.
What About the Petrol Hybrid Engine?
Mercedes-Benz has confirmed that internal combustion engine (ICE) enthusiasts won’t be left behind. A mild-hybrid petrol version of the third-generation GLA will arrive globally. It will feature Mercedes’ new ‘M 252’ 1.5-litre four-cylinder turbocharged petrol engine, integrated with a 48-volt starter-generator and an electrified 8-speed dual-clutch transmission (8F-eDCT).
Exterior Styling: Bolder Proportions and Aerodynamic Efficiency
Visually, the third-generation GLA adopts a more muscular, upright stance that aligns with Mercedes-Benz’s larger luxury SUV family.
Up front, the electric model features a closed-off panel grille embedded with multiple illuminated horizontal LED light strips. An illuminated chrome surround framing the panel connects seamlessly into sleek LED headlights featuring the signature Mercedes tristar daytime running light (DRL) pattern.
Key Exterior Innovations
- Dimensions & Stance: Measuring 4,565 mm in length (+153 mm over the older model) and riding on a 2,790 mm wheelbase (+61 mm), passenger legroom and rear knee clearance have increased noticeably.
- Aerodynamic Optimizations: Smooth underbody paneling, active air shutters in the front apron, flush pop-out door handles, and aerodynamically tuned wheel options ranging from 18 to 20 inches help lower wind resistance.
- Practical Cargo Storage: Alongside the rear 410-litre boot, the MMA platform layout allows for a dedicated 107-litre front trunk (frunk) under the hood—ideal for stowing charging cables and small travel bags.
Digital Sanctuary: Inside the MBUX Superscreen Cockpit
Inside, the new GLA trades conventional dashboard buttons for a high-tech cabin driven by Mercedes-Benz’s proprietary MB.OS operating system.
The main focal point of the interior is the optional MBUX Superscreen layout, which spans across the entire passenger dashboard under a single seamless glass panel:
- 10.25-Inch Digital Driver Display: Displays high-definition virtual instrument gauges, active safety telemetry, and full-screen AR navigation maps.
- 14.0-Inch Central Touchscreen: Serves as the main command center for climate control, media, vehicle drive modes, and cloud-connected apps.
- 14.0-Inch Front Passenger Display: Allows the front passenger to stream video content or adjust navigation routes independently without distracting the driver.
Premium Cabin Amenities
Beyond the digital screens, the GLA cabin incorporates sustainable fabrics, open-pore wood trims, and dynamic 64-colour LED ambient lighting.
A 16-speaker Burmester 3D Surround Sound System provides immersive acoustics, while an optional panoramic glass roof floods the interior with natural light. For tight off-road maneuvers or high curb parking, the 360-degree camera system includes a “transparent bonnet” function, rendering a virtual view of the terrain directly underneath the front axle.
Level 2+ ADAS & Safety Architecture
As with all modern Mercedes-Benz vehicles, safety remains a core engineering priority. The third-generation GLA comes fitted with an advanced sensor suite—including long-range radar, ultrasonic sensors, and surround cameras.
Standard and available driver-assistance technologies include:
- Active Distance Assist DISTRONIC: Maintains adaptive speed and safe distance from leading vehicles in highway traffic.
- Active Steering & Lane Keeping Assist: Provides smooth steering corrections to keep the vehicle centered in its lane.
- PRE-SAFE System: Pre-tensions seatbelts, closes windows, and emits an acoustic signal to protect occupant hearing milliseconds before an unavoidable collision.
- Automated Park Assist: Hands-free parallel and perpendicular parking with automatic braking controls.
Market Outlook: A Benchmark for Compact Luxury
The debut of the third-generation GLA marks a major milestone in Mercedes-Benz’s modular platform strategy. By offering an 800V ultra-fast charging EV model with up to 657 km of range alongside a future 48V mild-hybrid option, Mercedes-Benz ensures that compact SUV buyers do not have to choose between cutting-edge technology and everyday practicality.
Whether navigating busy urban commutes or embarking on long-distance road trips, the new GLA delivers the tech, efficiency, and comfort needed to remain a dominant force in the compact luxury crossover segment.
