Mercedes-Benz has revealed the long wheelbase version of its upcoming GLC EV at the Auto China 2026 show. Developed specifically for the Chinese market, the new GLC EV LWB focuses on comfort and practicality with the addition of a rear seat, while also offering a 3-row, 6-seat configuration. It is the only current-generation GLC to offer three rows of seating, highlighting Mercedes’ China-specific strategy for space-focused luxury vehicles.
Large dimensions, subtle design changes
The GLC EV LWB measures 4,933 mm in length, 1,902 mm in width and 1,710 mm in height. It rides on a 3,027 mm wheelbase, which is 55 mm longer than the standard model. The overall length has increased by 88 mm, while the height has increased by 66 mm.
Visually, the differences are noticeable but not dramatic. The rear doors are longer, the window area is increased and the quarter glass extends forward. Apart from these changes, the overall design remains similar to the standard GLC EV, including the lighting signature, grille and bumper design.
6-seater cabin with premium rear focus
The biggest update is inside, where the GLC EV LWB gets a 2+2+2 seating layout. The second row features individual captain seats with power adjustment, heating, ventilation and massage functions, emphasizing rear passenger comfort.
The dashboard layout remains unchanged, with a large 39.1-inch MBUX hyperscreen running the latest MB.OS software. The SUV also features a fixed panoramic glass roof with nine levels of transparency, which adds to the feeling of space inside the cabin. On the safety front, the GLC EV LWB is equipped with 11 airbags, a 360-degree camera and ADAS suite. The 6-seater version also gets easy access to the third row and a dedicated escape route for emergency exits.
Battery, range and fast charging
Powering the China-spec GLC EV LWB is an 85.5 kWh battery pack paired with a dual-motor all-wheel-drive setup. The SUV offers a claimed CLTC range of 680 km, which can be extended to 703 km depending on the configuration.
Interestingly, the standard wheelbase version gets a larger 94 kWh battery pack, but the smaller unit in the LWB model is likely due to packaging constraints from the third row layout. The GLC EV LWB supports 320 kW DC fast charging, charging the battery from 10% to 80% in just 22 minutes.
S-Class derived chassis tech
One of the main highlights is the use of chassis technology derived from the S-Class. Mercedes claims that the standard steel suspension offers comfort levels equivalent to the air suspension. For buyers seeking more, optional Airmatic air suspension and rear-axle steering are available, which improve ride quality and dynamics, especially given the larger dimensions.
The GLC EV LWB is currently exclusive to the Chinese market and is expected to go on sale later this year. It will compete with models like the BMW iX3 LWB, which is also expected to be launched in long-wheelbase format. While Mercedes-Benz hasn’t confirmed plans for India, the brand’s history of introducing long wheelbase models like the E-Class and V-Class means the possibility can’t be completely ruled out.
