2026 Beijing Auto Show: All-New Mercedes-Benz Long-Wheelbase Electric GLC SUV Debuts with 3,027mm Wheelbase and 700km Range

The 2026 Beijing Auto Show has officially kicked off with a spectacular display of automotive innovation, and Mercedes-Benz has seized the spotlight with the world premiere of its all-new long-wheelbase electric GLC SUV. Unveiled during the Mercedes-Benz Brand Night event on the eve of the show, this groundbreaking model marks a pivotal moment in the automaker's electrification strategy, combining the iconic GLC lineage with cutting-edge EV technology tailored specifically for the Chinese market.

The new Mercedes-Benz long-wheelbase EQC GLC SUV (hereafter referred to as the long-wheelbase electric GLC) is built on a dedicated electric platform and features a stretched wheelbase of 3,027mm, a substantial increase over the standard model. This extended wheelbase not only enhances interior spaciousness but also positions the vehicle as a direct competitor to other premium long-wheelbase electric SUVs in the segment. The battery pack is a high-capacity 89kWh unit, enabling a targeted driving range of over 700 kilometers on the CLTC cycle, addressing one of the key concerns of EV buyers—range anxiety.

From a design perspective, the long-wheelbase electric GLC adopts Mercedes-Benz's latest design language, characterized by a futuristic and highly illuminated front fascia. The highlight is the newly designed illuminated grille, which incorporates 942 polycarbonate backlit particles. When approached, these particles light up sequentially, creating a mesmerizing wave effect that enhances the vehicle's technological appeal. The headlights also feature distinctive star-shaped elements, with white diagonal daytime running lights that add a sense of dynamism and elegance. This combination of light and form underscores Mercedes-Benz's commitment to blending luxury with digital innovation.

Moving to the side profile, the extended wheelbase is immediately apparent, giving the vehicle a sleeker, more elongated silhouette. The body length measures 4,933mm, and with a wheelbase of 3,027mm, it surpasses the dimensions of the long-wheelbase gasoline-powered GLC, promising significantly more legroom and cabin comfort. The design lines flow smoothly from the front to the rear, emphasizing a sense of movement even when stationary. The long wheelbase also contributes to improved driving stability and ride comfort, a key consideration for the Chinese market where rear-seat comfort is paramount.

At the rear, the long-wheelbase electric GLC features a full-width taillight assembly, again incorporating star-shaped lighting elements that echo the front headlamps. The design is clean and sophisticated, with a layered rear bumper and chrome accents that elevate the overall premium feel. A notable functional addition is the 128-liter front trunk (frunk), providing extra storage space for items like charging cables or small luggage, further enhancing the vehicle's practicality for daily use.

Inside the cabin, Mercedes-Benz has pushed the boundaries of digital luxury. The centerpiece of the interior is a massive curved screen that spans nearly the entire width of the dashboard. This screen is not merely for show—it features 1,000 individually controllable LEDs with dual-zone independent dimming, allowing the driver and front passenger to adjust brightness levels separately. The screen houses the latest MBUX infotainment system, which now includes the “Xiao Ben” (Little Ben) virtual assistant. This assistant integrates ByteDance's large language model (Doubao) with advanced 3D graphics technology, enabling natural language understanding and support for regional dialects such as Cantonese. This localized approach demonstrates Mercedes-Benz's deep understanding of the Chinese market.

In terms of configuration, the long-wheelbase electric GLC is loaded with premium features. It includes wireless smartphone charging, dual cup holders, and a Burmester 19-speaker surround sound system that promises an immersive audio experience. A large panoramic starry sky sunroof floods the cabin with light, creating an airy and luxurious atmosphere. Perhaps the most significant interior innovation is the introduction of a six-seat layout for the first time in a Mercedes-Benz model. The optional six-seat configuration features two individual second-row seats with ventilation and heating functions, offering a level of comfort typically reserved for executive sedans. This move directly caters to Chinese families and business users who prioritize rear-seat luxury and flexibility.

Under the hood, or more accurately, under the floor, the long-wheelbase electric GLC is powered by a dual-motor all-wheel-drive system. The total system output is 310 kW (approximately 416 horsepower) with a combined torque of 800 Nm, ensuring brisk acceleration and confident all-weather performance. The eATS 2.0 electric drive unit features a radial-flux motor and a two-speed transmission, optimizing efficiency across a wide range of driving conditions. The 89kWh battery pack supports fast charging, and Mercedes-Benz claims that a 20-minute charge can provide enough energy for two weeks of commuting, depending on driving habits and conditions. This rapid charging capability is crucial for reducing downtime and making electric vehicle ownership more convenient.

The debut of the long-wheelbase electric GLC at the 2026 Beijing Auto Show underscores Mercedes-Benz's strategic focus on the Chinese market, which remains the world's largest and most competitive electric vehicle market. By offering a tailor-made product with an extended wheelbase, localized infotainment, and flexible seating options, the automaker is directly addressing the preferences of Chinese consumers. The 700km-plus range also alleviates range concerns, while the advanced charging technology promises to minimize waiting times. With its blend of luxury, technology, and practicality, the new long-wheelbase electric GLC is poised to set new benchmarks in the premium electric SUV segment.

As the automotive industry continues its rapid transition toward electrification, Mercedes-Benz's latest offering at the 2026 Beijing Auto Show demonstrates that legacy automakers can still innovate and compete aggressively. The long-wheelbase electric GLC is not just a car; it is a statement of intent—combining the heritage of the three-pointed star with the demands of a new energy era. For consumers and enthusiasts alike, this model represents a compelling option that does not compromise on luxury, space, or performance. The 2026 Beijing Auto Show has many stars, but the new Mercedes-Benz long-wheelbase electric GLC SUV shines particularly bright.
