Mercedes has introduced the third-generation GLA, including an electric variant with a reported range of up to 657 km and a cabin that can be equipped with the MBUX Superscreen. The German automaker is positioning the model against established European rivals and newer entrants in the premium market. The electric and petrol-powered versions have distinct specifications, so figures for one should not be assumed to apply across the range.
The new GLA’s proportions reflect a broader redesign, not a minor facelift. Compared with its predecessor, the body is 20 millimeters lower. The wheelbase is 61 millimeters longer, and the rear track is 31 millimeters wider. Its reported length is approximately 4.56 meters. Together, the revised dimensions give the compact SUV a wider, lower stance, while the longer wheelbase supports improved cabin packaging.
The luggage compartment holds 410 liters, 70 liters more than in the previous model. The larger capacity and longer wheelbase point to a practical focus alongside the GLA’s technology and electrification push. These packaging figures describe changes to the vehicle itself, not a regulatory test result.
Interior and Technology
The MBUX Superscreen is an option that combines three displays across the dashboard. The GLA also introduces Mercedes-Benz’s MB.OS operating system, part of the company’s shift toward software-driven vehicle systems. The Superscreen is not standard across every version.
The cabin’s digital focus comes alongside physical changes to the vehicle. A longer wheelbase can help make better use of interior space, while the larger luggage compartment adds capacity for everyday use. The GLA’s technology package and revised proportions are basic to its role as the third generation of Mercedes’ compact SUV.
Electric Powertrains and Range
The electric GLA is reported to offer up to 657 km of range, depending on version and equipment. That is a maximum claim, not a guaranteed real-world distance. Range varies with specification and driving conditions. The electric model uses an 800-volt electrical architecture, while petrol-powered versions belong to a separate part of the range.
Mercedes is also expected to introduce electrified combustion-engine versions in early 2027. Their arrival would extend the GLA range beyond the electric model as the Spanish market continues its transition toward electrification.
Market Position and Competition
The GLA arrives as competition in the premium compact SUV market intensifies. Mercedes is contending with established European manufacturers such as BMW and Audi, while Chinese brands are also seeking buyers in Europe. The new model’s electric range and revised packaging are intended to strengthen its appeal, alongside its digital technology. The wider electric SUV market includes models such as the BYD Atto 2, whose appeal to Spanish buyers is discussed in this analysis of the BYD Atto 2.
The first units of the new GLA are expected to reach Spanish dealerships in the third quarter of this year, with the base electric model starting at €54,000. Its launch pairs a redesigned compact-SUV package with an electric option and an 800-volt architecture. Mercedes-Benz’s latest software platform is also part of the offering.
