Mercedes Reveals All-Electric 2026 GLB With More Power, Longer Range and Built-In ChatGPT

By bike_ev_admin December 9, 2025 3 min read

Mercedes-Benz has unveiled the next-generation all-electric GLB, replacing the previous EQB and marking a major step forward for the brand’s compact SUV lineup. With a new 800-volt architecture, larger battery, stronger performance, expanded interior space, and a fully AI-enhanced infotainment system powered by ChatGPT, the new GLB pushes the brand further into its digital and electric future.

Two Powertrains: GLB 250+ and GLB 350 4Matic

The GLB launches with two electric variants.

GLB 250+ (RWD)

268 hp
247 lb-ft torque (335 lb-ft with overboost)
0–60 mph: 7.4 seconds
Range: 392 miles (WLTP claim)
Single rear motor

This version focuses on maximum efficiency and range, making it the long-distance option in the lineup.

GLB 350 4Matic (AWD)

349 hp
380 lb-ft torque
0–60 mph: 5.5 seconds
Range: 382 miles (WLTP)
Dual-motor all-wheel drive

The AWD version delivers the performance expected from a modern luxury EV while maintaining a strong driving range.

Both trims use the new 85 kWh battery pack and benefit from Mercedes’ upgraded 800-volt fast-charging system.

Larger, More Practical Dimensions

Mercedes has reworked the GLB’s proportions to offer noticeably more interior room:

Length: 186.3 in
Width: 73.3 in
Height: 66.4 in
Wheelbase: 113.7 in (extended by 2.4 in)

The increased wheelbase translates into improved second- and third-row legroom. The GLB retains seating for up to seven passengers, depending on configuration.

Cargo volume increases to:

23.6 cu ft behind rear seats
Plus 4.5 cu ft in the new frunk

The longer body improves practicality, while the larger turning circle (39 ft) reflects the SUV’s expanded footprint.

New Design Language With Full-Width LED Lighting

Mercedes has given the electric GLB a refreshed exterior identity:

A cleaner, EV-specific enclosed grille
New star-pattern daytime running lights
Full-width light bars front and rear
Vertical taillights inspired by the brand’s latest concept vehicles
Aerodynamic wheel options

The redesign establishes a more futuristic look while keeping the GLB’s recognizable boxy profile.

A Nearly 40-Inch Digital Dashboard

Inside, Mercedes transitions the GLB into a fully digital experience with the optional Superscreen layout:

10.25-inch digital cluster
14-inch central touchscreen
14-inch passenger display

Totaling almost 40 inches of screen space, the updated cabin removes much of the physical trim in favor of an all-glass, minimalistic design.

All displays run the new MBUX Gen-4 system, powered by the Unity Engine for smoother graphics and responsive animations.

ChatGPT4o Integration and AI-Driven Controls

The new GLB introduces the most advanced AI system ever installed in a Mercedes compact SUV:

MBUX Virtual Assistant powered by ChatGPT4o
Microsoft + Google AI cloud integration
More conversational voice controls
Context-aware cabin automation
Predictive recommendations

The system can adjust comfort settings, manage navigation, curate entertainment, and answer complex queries, marking a major leap in in-car AI usability.

Charging, Efficiency, and Architecture

The 800-volt electrical setup enables:

Faster DC charging
Better thermal efficiency
Reduced cable weight
Higher power delivery consistency

Mercedes claims 10–80% charging in less than 30 minutes on high-power chargers, though official European and U.S. charging times will vary.

Pricing and Availability

European pricing provides an indicator of what to expect globally:

GLB 250+: ~€62,900 (~$68,700)
GLB 350 4Matic: ~€66,300 (~$72,400)

U.S. pricing will be announced closer to launch. Mercedes also confirmed more affordable EV and hybrid variants arriving later.

The all-electric GLB goes on sale in 2025, with deliveries beginning in early 2026.
