Mercedes-Benz GLB-Class to undergo full model change in 2026: A complete look at the compact SUV that will leap forward with next-generation technology

Mercedes-Benz will fully redesign its new GLB-Class compact SUV and release it in 2026.

The GLB-class is positioned between the GLA-class and GLC-class in Mercedes-Benz’s SUV lineup. Featuring a three-row seating layout that accommodates up to seven passengers despite its compact size, the GLB has proven highly popular, especially among families. Since its debut at the 2019 Shanghai Motor Show, the current model, the first-generation GLB, quickly established its presence in global markets with its packaging that combines practicality with Mercedes-Benz’s signature high-quality feel. It was introduced to the Japanese market the following year in 2020, and has been praised for its maneuverability in urban areas and its cargo capacity and interior space that are suitable for weekend outdoor activities. While significant improvements were made in 2023, including a refined design and enhanced equipment, this full model change marks the first complete overhaul in approximately seven years and is expected to symbolize the next generation of Mercedes-Benz.

Yes, I understand. I will summarize the contents of the previous article in bullet points.

Mercedes-Benz new GLB-Class full model change in 2026

In recent years, Mercedes-Benz has been accelerating its electrification and digitalization efforts while optimizing its product portfolio. In particular, in the compact car segment, the company has made it clear that it will focus on profitable premium models, and has announced the discontinuation of the A-Class hatchback and sedan (including the long-wheelbase version for the Chinese market) as well as the B-Class. Amid this strategic shift, the GLB-Class will remain at the core of the new-generation compact model lineup, alongside the CLA-Class and GLA-Class. This suggests that Mercedes-Benz has determined that the growing global demand for the SUV segment and the GLB-Class’s unique positioning (as a three-row compact SUV) remain important to its future strategy.

The next-generation GLB-Class is more than just a model change; it is expected to serve as a showcase for Mercedes-Benz’s next-generation technologies. Its core feature is the adoption of the newly developed “Mercedes-Benz Modular Architecture (MMA)” platform. The MMA platform will also be used for future Mercedes-Benz compact models, such as the next-generation CLA-Class. Its greatest feature is its flexibility, enabling efficient production of both conventional internal combustion engine (ICE) models and fully electric vehicle (EV) models using the same basic structure. This will serve as an important foundational technology for quickly responding to changes in market demand and regulations during the transition to electrification facing the entire automotive industry. Designed with electrification in mind, the MMA platform not only optimizes battery space and enables efficient energy management, but also enables the effective integration of electrification technologies such as mild hybrid systems, even in ICE models . The adoption of this new platform is expected to enable the new GLB-Class to achieve significant improvements over the current model in all aspects, including driving performance, comfort, safety, and environmental friendliness.

Mercedes-Benz New GLB-Class 2026 Full Model Change Exterior

The new GLB-Class will also undergo a major transformation in its exterior design. The previewed prototype and the CG renderings based on it clearly reflect the latest Mercedes-Benz design language. The front mask has been completely redesigned, evolving from the relatively conventional impression of the current model to a more advanced and powerful look. Of particular note is the design of the headlight units. The interior is expected to incorporate LED daytime running lights featuring Mercedes-Benz’s iconic three-pointed star motif, giving the new GLB-Class a strong, instantly recognizable identity. The shape and placement of the radiator grille have also been revised, and it is now mounted slightly lower than the current model, emphasizing a low center of gravity and a stable stance. The front bumper design has also been revamped, with more dynamic air intakes and other features, likely combining SUV-like toughness with sportiness.

Looking at the side view, while the current model retains its relatively linear and boxy silhouette, refined changes have been made to the details. In particular, the lower edge of the window line, while the current model’s rear end kicks up, is expected to have a smoother rising line toward the rear on the new model. This will emphasize the car’s elongated and elegant appearance. It has also been confirmed that the side mirrors will be relocated from the base of the A-pillar to the door panel, which is likely to contribute to improved aerodynamic performance and forward visibility. Furthermore, retractable door handles, which have been increasingly adopted in Mercedes-Benz’s premium models in recent years, are likely to be installed, at least on higher grade models. This will create a flush surface (a smooth surface configuration with few bumps and indentations) on the body side, enhancing the modern and clean impression.

The rear section is expected to see the most dramatic changes in the new GLB-Class’s design. The prototype’s camouflage is particularly thick, suggesting significant changes. The expected design is likely to feature LED taillights with an inverted U-shape or horizontal design that span the entire width of the tailgate. This will significantly enhance the sense of width and modernity of the rear view. Additionally, the Mercedes-Benz brand logo (three-pointed star) will be placed in the center of the tailgate, and the license plate, which was previously located on the tailgate on the current model, is expected to be moved to the bottom of the rear bumper. This change in the license plate position is a relatively bold move for Mercedes-Benz, and it will give the entire rear end greater design freedom, creating a cleaner, more sophisticated impression. These changes will likely give the new GLB-Class a completely different, more modern and striking rear view than the current model.

The new GLB-Class is expected to be slightly larger than the current model. Specific measurements include a length of approximately 4520mm, width of approximately 1835mm, height of approximately 1680mm, and wheelbase of approximately 2845mm. Compared to the current model (length 4640mm x width 1835mm x height 1700mm, wheelbase 2830mm), the length may be slightly shorter, while the wheelbase may be extended by 15mm. (Note: Size estimates vary depending on the source. Some reports suggest the length will be longer than the current model.) While the width will remain the same, the longer wheelbase is a benefit of the newly developed MMA platform, which directly translates into increased interior space, particularly legroom in the rear and third-row seats. Platform optimization further enhances the GLB-Class’s inherent strength of maximizing passenger space and cargo capacity within a limited body size. This is expected to further improve comfort and convenience for family use.

Mercedes-Benz New GLB-Class 2026 Fully Redesigned Interior

Looking at the interior, the new GLB-Class will evolve into an innovative space that strongly reflects Mercedes-Benz’s ongoing digitalization initiative. Its most notable feature is the adoption of a large infotainment display that completely redesigns the dashboard. This evolves from the previous style, which integrated the driver’s instrument cluster and central media display, and is expected to feature an “MBUX Superscreen” or equivalent system, which is covered by a single glass panel extending to the front passenger seat. This will create a futuristic and clean cockpit design and allow passengers easy access to navigation and entertainment functions. The infotainment system will be the latest generation of MBUX (Mercedes-Benz User Experience) , which will utilize AI to enhance voice recognition and provide more intuitive and personalized operation.

The overall interior quality will also be further improved from the current model. By reviewing the materials used and improving the ambient lighting effects, the new car is expected to offer a premium passenger space that exceeds its class. Furthermore, the interior design will not just focus on a new look, but also on improving functionality. By adopting the MMA platform and revising the basic design, the interior layout will be optimized, with improvements being made to the third-row seats, a major feature of the GLB-class. While the current model already had enough space for adults to sit on short distances, in addition to being suitable for emergency use, the new model is expected to further enhance comfort and practicality as a seven-seater SUV. Storage space will also be expanded, and convenient features such as USB ports will also be enhanced.

Mercedes-Benz New GLB-Class 2026 Full Model Change: Powertrain

The powertrain is a key element in the evolution of the new GLB-Class, with major updates being made to both the internal combustion engine and electric vehicle (EV) models.

Mercedes-Benz new GLB class 2026 full model change internal combustion engine model

First, for the internal combustion engine models, a newly developed 1.5L inline-four-cylinder gasoline turbo engine is expected to replace the 1.4L gasoline turbo and 2.0L diesel turbo engines currently available in the current models. This new engine employs a Miller cycle system for improved combustion efficiency and will be paired with a 48V mild hybrid system. The mild hybrid system utilizes an electric motor to assist the engine during launch and acceleration, contributing to smooth acceleration and improved fuel economy. During deceleration, energy regeneration is performed, storing electricity in the battery. Depending on the specification, the engine is expected to offer multiple maximum outputs, ranging from 134 PS (100 kW), 163 PS (120 kW), and 190 PS (140 kW). This will be supplemented by approximately 27 PS (20 kW) generated by the electric motor (ISG: Integrated Starter Generator). The car will be paired with an 8-speed dual-clutch transmission (8G-DCT) that combines efficiency with a direct shifting feel, and will be available in front-wheel drive (FF) and all-wheel drive (4MATIC). The adoption of this new powertrain will achieve fuel economy comparable to that of conventional diesel engines while providing the light and nimble driving feel unique to gasoline engines. The plug-in hybrid (PHEV) model, which was available in some markets for the current model, is expected to be discontinued from the lineup. This is thought to be due to a focus on EV models with longer driving ranges and improved performance of the mild hybrid system.

The combination of a newly developed 1.5L gasoline turbo engine and mild hybrid system is expected to significantly improve fuel economy. A specific target of 15.5km/L (WLTC mode equivalent) has been suggested, which is comparable to the 13.4km/L of the current model’s 1.4L gasoline turbo (FF) and 15.8km/L of the 2.0L diesel turbo (4WD), and is in fact extremely good fuel economy for a gasoline model. In response to growing environmental awareness, improved fuel economy will be a key selling point for the new GLB-Class. And for customers seeking even greater environmental performance, the zero-emission EV model will be a strong option. The significantly extended driving range will significantly improve the practicality of the EV model, making it an attractive option for a wider range of customers.

Mercedes-Benz new GLB class 2026 full model change electric vehicle model

Another key feature of the new GLB-Class is the all-electric vehicle (EV) model. The current EV model, the EQB, will be integrated into the GLB-Class lineup in the next generation model. EV models based on the MMA platform may use a different drivetrain than internal combustion models. The basic model is expected to be rear-wheel drive (RWD) with a single electric motor mounted at the rear. This motor will produce a maximum output of around 272 PS (200 kW), providing the powerful yet quiet acceleration you expect from an EV. Furthermore, for performance-conscious customers, an all-wheel drive (AWD) model will be available with an additional front-mounted electric motor (maximum output of around 109 PS/80 kW) driving both the front and rear wheels. The AWD model not only delivers higher overall system output, but also optimizes torque distribution between the front and rear wheels according to road conditions, achieving superior traction and driving stability.

It’s worth noting that the EV model will feature a newly developed two-speed transmission for electric vehicles. While most EVs use a single gear, the two-speed transmission allows for both powerful acceleration when starting and improved efficiency (electric fuel consumption) at highway speeds. The latest generation battery will also be installed, improving energy density. The standard battery capacity is expected to be around 58 kWh, with a high-capacity version expected to be around 85 kWh. This will significantly extend the vehicle’s range, with the 85 kWh battery offering a maximum of 680 km in WLTP mode, or possibly even up to 750 km, depending on the source. This is a significant improvement over the current EQB’s range (approximately 500 km in WLTP mode), dramatically improving convenience for both everyday use and long-distance driving. Improved charging performance is also expected, allowing for faster charging times.

Mercedes-Benz New GLB-Class 2026 Full Model Change Safety Features

In terms of safety, the new car will be equipped with the latest, most advanced safety and driver assistance systems, living up to the Mercedes-Benz name. Improved radar sensors and cameras further enhance the vehicle’s ability to recognize the surrounding environment. The adaptive cruise control (DISTRONIC) now maintains a safe distance from the vehicle ahead and automatically decelerates around curves and junctions. The steering assist function has also been improved, allowing lane-keeping assistance to operate in a wider range of situations. One particularly noteworthy feature is the Active Lane Changing Assist. When the driver activates their turn signal on highways, the system automatically changes lanes after checking for safety around them. Additionally, in the unlikely event of an emergency, such as the driver losing consciousness while driving, the Active Emergency Stop Assist system will automatically maintain the vehicle in its lane while gently decelerating and ultimately bringing it to a safe stop. These advanced features significantly reduce driver burden and the risk of accidents. Of course, the latest generation of basic safety equipment is also installed, such as collision damage mitigation braking (active brake assist) and blind spot assist, which monitors blind spots, ensuring high safety in all situations.

Finally, let’s talk about the price and release date of the new GLB-Class. With the new GLB-Class undergoing such significant evolution, it’s inevitable that pricing will rise from the current model. The current model’s entry-level “GLB 180” starts at approximately 6.44 million yen in Japan, but the new model is expected to have an entry price starting at around 6.6 million yen, reflecting its enhanced equipment and adoption of new technologies. Depending on the pricing of each grade of the internal combustion engine model and the newly added EV model, the range of options will expand, and the higher-end grades may be priced close to the current AMG model.

The much-anticipated world premiere is scheduled to take place in 2026, after which sales will begin in each country’s market. The timing of its introduction to the Japanese market has not yet been decided, but it is expected to be introduced relatively soon after the world premiere.
