As mercedes-Benz's most popular model of the past decade, each generation of C-Class has leapfrogged with extraordinary strength, setting new standards of luxury and comfort. With the design aesthetic of "sensuality and purity", the digital experience of all scenarios, and the exclusive luxury of comfort, the new long-wheelbase C-class car once again expands the dimensional definition of the comfort zone and enters the "comfort zone" of Chinese customers.
Comfortable driving, luxurious power of technological innovation
The M254, an in-line four-cylinder engine powered by the new long-wheelbase C-Class, provides outstanding dynamic performance of static, smooth, economical, intelligent and energetic through leading engine technology. The ISG integrated starter generator on the M254 engine eliminates the direct connection of the belt to the engine, greatly improving the energy conversion efficiency; at start-up, the engine speed is rapidly increased to achieve a silky smooth and quiet induction start; and the additional 15 kW power and 200 Nm torque are provided to further improve the power performance of the engine. The M254 engine is based on the twin-scroll technology of The Mercedes-AMG Formula 1 racing car, which further reduces turbo lag with optimized exhaust pulse position, resulting in faster acceleration response and more power. CONISHAPE cylinder wall honing, NANOSLIDE cylinder wall coating, and crankshaft bias technology significantly reduce engine block weight and friction losses. The "diamond-hard" piston ring polymer coating made of carbon fiber and graphite resin maximizes friction losses and efficiency. Electromagnetic porous atomization technology increases the injection pressure to 350 bar and further refines the oil droplets, making them more precise and efficient, and burning more fully. Thanks to these technologies, the M254 engine achieves powerful and efficient performance, achieving a power increase of 100 kW/L. The C 260 L sports sedan/sedan has a maximum output of 150+15 kW, a maximum output torque of 300+200 Nm, and an acceleration of only 7.7 seconds per 100 km/h, an increase of 0.8 seconds over the previous generation C-Class.
In addition, the new generation of intelligent driver assistance system derived from the new S class covers seven daily driving scenarios, including high-speed following, lane change assistance, lane keeping, active braking, steering assistance, blind spot warning, intelligent parking, etc., to help drivers calmly cope with various road conditions.

Whether speeding down the highway or passing through the downtown area during rush hour, the new long-wheelbase C-Class is always quiet and pleasant. The new long-wheelbase C-class car strictly controls noise transmission, using environmentally friendly liquid damping and other sound insulation materials on the surface of the chassis and frame, which increases the coverage area by 50% compared with the previous generation model; under the engine compartment and A-pillar, the enhanced engine noise isolation component further blocks the vibration and noise of the powertrain; the resonant block is added to the position of the gearbox and the drive shaft; and the acoustic foam filling for the rear cockpit is further increased on the already quiet and pleasant overseas standard axle version. In addition to the strict control of the noise transmission path, the new long wheelbase C-class also optimizes the internal components and bracket structure of the engine, actively reduces the vibration generated during the power transmission, and reduces wind noise and tire noise with a unique body design, comprehensively improving the noise sound source.
The handling performance of the new long-wheelbase C-Class has also been further improved, with a more flexible direct steering system that makes driving easier and easier, and special chassis tuning according to Chinese road conditions to reduce the damping of the suspension at low to medium speeds and reduce the feeling of bumps in urban sections.
In addition to a large number of "invisible" driving adjustments, the new long-wheelbase C-class car also enhances the luxurious comfort of the car from more "visible" details. The rear space is 89 meters longer than the overseas version, the rear seats are 22 mm thicker and 14 mm longer than the previous generation, and combined with the headrest cushions, comfortable rear headrests, integrated central armrests, sunlight sunshade rear adjustment buttons, rear gentleman buttons and other comfortable upgrades, bringing a first-class luxury experience.
