Mercedes-Benz Long-Wheelbase GLE Debuts in China Ahead of September Launch

Mercedes-Benz Long-Wheelbase GLE Makes China Debut

Mercedes-Benz AG announced on August 21 that its new Mercedes-Benz long-wheelbase GLE made its global debut at the 2026 Chengdu Motor Show in China and is scheduled for an official launch on September 16. Developed specifically for the Chinese market, the luxury SUV extends the standard GLE package with additional rear-seat space, comfort functions, localized digital features, and advanced driver-assistance capabilities. The model combines a longer body configuration with the company’s 4MATIC full variable all-wheel-drive system and a 3.0L EVO inline six-cylinder engine. Its technology package also incorporates China-developed entertainment and artificial intelligence functions designed around local customer preferences.

Extended Wheelbase Enhances Rear-Seat Comfort

The SUV has a 3,115 mm wheelbase, making it 120 mm longer than the version sold outside China. This additional length creates 1,020 mm of rear-seat space, while the rear seatbacks can be adjusted between 31° and 38° to support different passenger preferences. Rear occupants also receive three-level heating for both the seats and headrests, together with a multi-point seat massage function. These changes place a strong emphasis on rear-passenger comfort and reflect the model’s positioning as a premium long-wheelbase vehicle tailored to the China luxury SUV market.

Standard 4MATIC AWD and Six-Cylinder Powertrain

Across the lineup, the vehicle comes standard with the 4MATIC full variable all-wheel-drive system and a 3.0L EVO inline six-cylinder engine. The powertrain produces a maximum output of 280 kW and peak torque of 560 Nm, while an electric auxiliary compressor is also included as standard equipment. The combination is intended to provide strong performance while maintaining the all-weather traction expected from a premium SUV. By making the all-wheel-drive system, engine configuration, and electric auxiliary compressor standard across the range, Mercedes-Benz is positioning the model around a consistent performance specification rather than relying on extensive powertrain differentiation between variants.

China-Specific Rear-Seat Entertainment and AI

The cabin introduces a China-developed premium rear-seat entertainment system with dual 12.9-inch displays. An on-device multimodal vision-language model can proactively recommend personalized content according to the age of individual passengers. The vehicle also uses the new Mercedes-Benz Operating System, or MB.OS, architecture tailored for the Chinese market. Its Mercedes-Benz virtual assistant, “Xiaoben,” integrates the Doubao AI large model, a hyper-realistic speech synthesis engine, and 3D graphics technology, allowing the system to handle complex multi-turn conversations. The localized software approach expands the role of digital services within the rear passenger experience.

Momenta Technology Supports Advanced Driver Assistance

Driver assistance is also localized through technology from Beijing Momenta Technology Co., Ltd. The SUV is equipped with Momenta’s R6 large model and supports Urban Navigation on Autopilot and Highway NOA. The driver-assistance system can subsequently be upgraded to use the Momenta R7 World Model, enabling parking-space-to-parking-space assisted driving. This progression gives the vehicle a technology path that can expand its assisted-driving functionality after launch, while the integration of local AI and navigation capabilities aligns the model with the rapidly developing intelligent-vehicle ecosystem in China.

NVH Measures and Premium Audio System

Mercedes-Benz is also emphasizing refinement through a standard package of noise, vibration, and harshness measures. The SUV receives NVH noise-reduction components, noise-reducing tires, and double-layer acoustic glass for the front and rear side windows. The cabin is further equipped with a Burmester 3D Surround Sound System that supports Dolby Atmos. Together, these features complement the increased rear-seat space and comfort equipment by targeting a quieter and more immersive passenger environment. The combination of acoustic treatment, premium seating functions, and advanced entertainment technology reinforces the model’s focus on rear-seat luxury.

China-Focused Luxury SUV Strategy

The global debut at the 2026 Chengdu Motor Show establishes the latest long-wheelbase GLE as a China-focused luxury SUV with a combination of extended rear accommodation, standard all-wheel drive, six-cylinder performance, and localized digital technology. Its September 16 launch will bring the production model to the next stage of its market introduction. The vehicle’s China-specific operating system, AI assistant, rear-seat entertainment, and Momenta-based driver assistance show how Mercedes-Benz AG is adapting both hardware and software to local requirements while retaining core premium-brand features.

Localized Technology Complements Premium Hardware

For Mercedes-Benz, the model also demonstrates how luxury vehicles can be differentiated through passenger-focused packaging and locally developed software. The extended wheelbase directly increases rear-seat accommodation, while adjustable seating, heating, massage, acoustic measures, and premium audio address comfort. At the same time, AI-based content recommendations, “Xiaoben,” and Momenta-assisted driving add localized digital functionality. The result is a vehicle strategy that combines established mechanical hardware with China-specific technology and services, creating a product specification designed around the expectations of the local premium SUV market.
