Mercedes has revealed its second-generation GLB in full, offering seven-seat versatility and almost 400 miles of range.
On sale early 2026, the latest iteration of the compact SUV will be available as five- or seven-seater and will quickly expand to offer more pure electric versions along with hybrids.
Built on Mercedes’ new MMA architecture for compact cars, it carries over the GLB’s boxy looks but revamps the interior with latest Mercedes technology.
The first fully electric versions to arrive will be the 272hp GLB 250+ with EQ Technology and the 354hp GLB 350 4Matic all-wheel-drive version.
Both feature an 85kWh (useable) lithium-ion battery and offer a range of up to 392 miles (631km) for the GLB 250+ and 382 miles (615km) for the 350 4Matic. The 800V electric architecture means up to 161 miles (260km) of range can be added in 10 minutes.
The model range will then expand soon after launch to add additional battery-electric variants, including an entry-level model as well as mild hybrids in three power levels. These will be able to drive purely electrically and recuperate energy under certain conditions. Buyers will have the choice between front-wheel-drive and 4Matic versions.
4Matic models come with a Terrain Mode while a ‘Transparent Bonnet’ function provides a virtual view under the entire vehicle, making it easier to manoeuvre in rough terrain. Towing capacity is up to two tonnes, giving the ability to tow a full-size caravan according to the Stuttgart brand, and the GLB offers a drawbar load of 100kg so e-bikes can be taken along on weekend trips and holidays.
Suspension with adaptive damping comes as standard in combination with 20-inch wheels. Drivers can use the Dynamic Select switch to change damping characteristics, choosing between Comfort mode with more comfortable damping characteristics or Sport mode for a sporty, firm setting.
Compared to its predecessor, the new electric GLB offers a noticeable increase in headroom in the first two rows of seats, helped by a higher roofline as well as a standard panoramic roof. Passengers also get more legroom in the rear.
Boot space stands at 540/480 litres (five/seven-seater), increasing to 1,715/1,605 litres with the rear seatbacks folded down. The GLB also comes with 127 litres of space in the ‘frunk’.
The “high-quality, radically redesigned interior” offers the optional floating MBUX Superscreen, featuring a 10.25-inch screen for the driver, a 14-inch central display and a 14-inch screen for the front passenger, all behind a large glass surface. The cabin also gets a floating high-positioned centre console with an additional storage compartment. Mercedes has also reintroduced a physical rocker switch for the limiter and Distronic system, as well as a roller for volume control.
The large standard panoramic roof can be fitted with the optional Sky Control feature that switches back and forth between transparent and opaque (milky) for more privacy (optional extra) and comes with 158 stars that are illuminated.
The GLB also comes with the new MBUX Virtual Assistant based on generative AI, and offers a range of driver assistance systems, including Distronic distance control as standard in Europe. Assistance systems are now available under the name MB.Drive.
The new GLB fully operates on the inhouse Mercedes‑Benz Operating System (MB.OS); an AI-enhanced system that makes it possible to equip every vehicle with supercomputers connected to the Mercedes-Benz Intelligent Cloud. This enables regular over-the-air updates for the most important vehicle functions, including driving assistance systems. Additional functions can also be ordered via the Mercedes-Benz Store as Digital Extras.
Grades includes Progressive Line, AMG Line and AMG Line Plus as well as a Night Package and other equipment options.
