Mercedes-Benz files for electric C300L with 800V architecture in China

Mercedes-Benz has filed for the new electric C300L, a second powertrain variant of its locally produced C-Class EV, built on an 800V platform with a 230kW motor and LFP battery from CATL.

Mercedes-Benz has submitted the electric C300L for regulatory approval in China, according to a filing published by the Ministry of Industry and Information Technology (MIIT) and reported by the Chinese outlet Autohome. The new model is the second powertrain version of the locally produced next-generation electric C-Class family and is expected to become the entry-level option in the lineup.

Design and dimensions

The C300L adopts the brand's latest shield-shaped front grille, filled with dense dot-matrix chrome elements and a large three-pointed star emblem. Slim headlights blend into the grille, while air-intake-style trim on the front bumper and clean body lines give the car a youthful, tech-forward look. At the rear, a full-width light bar with circular light elements and a chrome-accented bumper add visual depth. Badging on the tailgate confirms the C300L is built by Beijing Benz, the company's joint venture in China.

According to the filing, the car measures 4,977 mm (196 inches) long, 1,876 mm (74 inches) wide, and 1,510 mm (59 inches) tall, with a wheelbase of 3,051 mm (120 inches). Approach and departure angles are 16 and 19 degrees, respectively.

Powertrain and battery

The C300L is powered by a single electric motor with a peak output of 230 kW (308 hp), enabling a top speed of 200 km/h (124 mph). The battery is a lithium iron phosphate (LFP) pack supplied by CATL's Fuding plant, while the battery assembly is carried out by Beijing Benz itself. The car is built on an 800V high-voltage architecture, which supports faster charging and improved efficiency.

No official price or range figures have been announced yet. The C300L is expected to join the electric C-Class lineup as a more affordable alternative to higher-spec versions, following the trend of other luxury brands offering multiple powertrain options in China's competitive EV market.
