2026 Mercedes-Benz Long-Wheelbase E-Class Launched with Doubao AI Integration Starting at 42.38k CNY

On November 2, 2026, the 2026 Mercedes-Benz long-wheelbase E-Class officially went on sale. According to IT之家, the sedan introduces a new naming scheme and a price range of 42.38-50.98万元 (CNY), with the E 300 L 晖银版 at 42.38万元, the E 300 L 鎏金版 at 46.68万元, and the E 300 L 星铂版 at 50.98万元.

The car is the first to feature a new AI intelligent cockpit developed independently and led for the first time by Mercedes-Benz's China R&D team. The system supports quarterly major OTA upgrades and is planned to appear on more internal combustion and pure electric models going forward. Inside, there is a 14.4-inch central display plus a 12.3-inch passenger display, a Mercedes virtual assistant that integrates the Doubao AI large model, and standard Huawei HiCar across the lineup. A digital twin 3D model of the car is designed to closely match the real exterior color and trim details, show live status such as doors and windows, and allow the user to operate window and sunshade functions directly through the 3D model. The interface is flexible, with freely adjustable cards in the navigation bar and quick-access bar, while multimedia and calling apps can appear in multitasking mini windows, so on-screen operations are said to feel as intuitive as using a phone.

The body measures 5 meters in length and 1.88 meters in width. On the equipment side, the E 300L 星铂版 adds a head-up display system, an in-cabin air conditioning package, and heated steering wheel as standard, while the E 300L 晖银版 and above add the signature 璀璨星环格栅 as standard. Publicly available information so far does not report any further developments after the launch.
