New (bigger) Mercedes-Benz GLB revealed

- 2nd-generation GLB moves to MMA architecture
- Wheelbase grows by some 60 mm to 2 889 mm
- EVs at launch in Europe; mild hybrids to follow
The new Mercedes-Benz GLB has been revealed in Europe, again offering up to 7 seats but now sporting an even roomier cabin.
Interestingly, the 2nd-generation GLB is the 2nd model (after the latest CLA) to switch to the Stuttgart-based firm’s MMA architecture. These underpinnings mean the new GLB will eventually be available in both fully electric and hybrid form.
According to Mercedes-Benz, the new GLB crossover – which will be available as either a 5- or a 7-seater – has grown compared to the original. In fact, measuring 4 732 mm from nose to tail, the 2nd-gen model is 48 mm longer than its forebear, while also standing 27 mm wider at 1 861 mm.
The wheelbase, too, is 60 mm longer at 2 889 mm (even eclipsing that of the current GLC), while the German firm claims head- and legroom in the 2nd row (which boasts a longitudinally adjustable bench) have increased by up to 64 mm and 68 mm, respectively. The 2 individual seats in the optional 3rd row, meanwhile, can now “comfortably accommodate” passengers up to 1.71 metres tall.
The 5-seater version’s luggage compartment is a claimed 45 units larger at 540 litres, a figure that’s expandable to up to 1 715 litres by dropping the 2nd row of seats. In fully electric derivatives, there’s also some 127 litres of storage space under the bonnet. Inside, the brand will offer the optional “MBUX Superscreen”, comprising a 10.25-inch instrument cluster, a 14.0-inch central display and a 14.0-inch front-passenger screen.
New GLB powertrains: fully electric and mild hybrid
So, what about the powertrains? Well, at launch in Europe, the GLB will be available exclusively in fully electric form, though 48-volt mild-hybrid derivatives will follow in “a few months”, according to Mercedes-Benz. Initially, a pair of EVs will be offered on the Old Continent, though additional battery-electric variants (including an “entry-level model”) are due to follow.
The GLB 250+ with EQ Technology features a rear-mounted electric motor offering 200 kW and 335 Nm. Thanks to an 85 kWh battery pack, the claimed WLTP range comes in at up to 631 km, a figure Mercedes-Benz describes as “unrivalled in its class”.
The GLB 350 4Matic with EQ Technology, meanwhile, adds a 2nd (front-mouted) motor, pushing peak system outputs to 260 kW and 515 Nm. Maximum single-charge range, however, dips slightly to 614 km, though the German firm claims this all-paw derivative will see off the 0-100 kph sprint in just 5.5 seconds (compared to 7.4 seconds for the GLB 250+).
Mercedes-Benz says DC fast-charging is possible at 800-volt charging stations with a charging capacity of up to 320 kW. However, the GLB can also use a 400-volt charging infrastructure. The AC charging capacity, meanwhile, tops out at 22 kW.
The upcoming hybrid variants will use a 1.5-litre, 4-cylinder petrol engine along with a “newly developed” 1.3 kWh lithium-ion battery, 48-volt technology and an electric motor integrated into the 8-speed dual-clutch transmission. Though Mercedes-Benz has yet to release full technical details, it does say this new mild-hybrid powertrain will initially be available in 3 outputs, with the choice between front- and all-wheel drive.
Mercedes-Benz South Africa has yet to confirm whether the new GLB is on the cards for the local market, though we’d speculate this model might arrive late in 2026. As a reminder, the original GLB debuted globally back in 2019, before touching down in South Africa in November 2020 (and then being updated in mid-2024).
The current range in Mzansi comprises the GLB220d 4Matic Progressive (from R1 147 432) and GLB220d 4Matic AMG Line (from R1 186 432), each employing a 2.0-litre, 4-cylinder turbodiesel engine delivering 140 kW and 400 Nm to all 4 corners.
