Which series does the Mercedes-Benz 400 belong to?

Mercedes-Benz models equipped with a 3.0T 333-horsepower V6 engine are all named 400, with the Mercedes S400 as an example. Appearance features of the Mercedes S400: In the minor facelift, Mercedes-Benz did not make many changes to the S-Class. The front end follows the brand's recent family style, featuring a larger and more sharply contoured grille. At the rear, the body-colored trim on the taillight clusters was removed and replaced with full LED light clusters, incorporating the reverse light design. This retains the original two-bar style while improving rear lighting effects. The redesigned front and rear bumpers have sharper lines, giving the S-Class a more youthful and sporty appearance. The high-brightness LED daytime running lights are exclusive to the S400 Hybrid and S600 models, highlighting the technological prowess of the hybrid system and the V12 engine. Engine of the Mercedes S400: To improve overall fuel efficiency, the S400 Hybrid's engine, like the THS, operates on the Atkinson cycle. Mercedes-Benz engineers adjusted the intake valve timing of this V6 engine, delaying its closure compared to the original S350, to achieve a compression stroke shorter than the power stroke. This leverages the Atkinson cycle principle for higher thermal efficiency. To counteract the significant power loss typical of Atkinson cycle engines, Mercedes-Benz engineers recalibrated the V6 engine in the S400 Hybrid, increasing the compression ratio from 10.7:1 to 11.7:1 and adjusting fuel injection and ignition timing. As a result, this Atkinson engine maintains the same peak torque of 35.7 kg·m as the original engine, with maximum horsepower even higher at 279 hp. The S400 Hybrid accelerates from 0 to 100 km/h in just 7.2 seconds and can reach the electronically limited top speed of 250 km/h. More impressively, thanks to the hybrid system's excellent performance, along with Start/Stop and brake energy recovery systems, it achieves over 12 km per liter of gasoline, reducing fuel consumption by 21% and CO2 emissions by 18%, making the S400 Hybrid the most fuel-efficient model in its class.

The Mercedes-Benz 400 is actually a common model designation within the Mercedes luxury S-Class lineup, typically referring to the S 400 variant. I must say, looking at Mercedes' history, the number 400 generally represents large-displacement engines or high-performance configurations, such as the V8 engines used in older models, though nowadays it mostly refers to V6 hybrid powertrains. As the flagship series of Mercedes-Benz, the S-Class has been the epitome of premium vehicles since its debut in the 1970s, offering exceptionally smooth and comfortable driving experiences with spacious interiors packed with high-tech features like air suspension and advanced driver assistance systems. However, there are other similarly numbered series in the market, such as the E-Class with its E 400, but when people mention 'Mercedes 400', it most commonly evokes the top-tier luxury experience of the S-Class.

Speaking of the Mercedes 400, I've driven my friend's car a few times, and it feels like it's essentially a specific model within the Mercedes S-Class lineup. The driving experience is incredibly smooth, with surprisingly quick yet quiet acceleration. The seats are super comfortable, making long trips almost bump-free. The interior luxury is beyond words—premium leather, a responsive tech screen, and a host of safety features like automatic braking. Although it consumes more fuel than a regular compact car, the hybrid version is actually quite fuel-efficient. Remember, this is a variant of the S-Class, not an independent series, so when purchasing, just look under the Mercedes S-Class catalog.

The Mercedes-Benz 400 model belongs to the flagship S-Class series of Mercedes-Benz, typically equipped with high-performance engine systems such as a 3.0-liter six-cylinder engine, delivering approximately 300 to 330 PS of horsepower, emphasizing high-efficiency power. Its design focuses on aerodynamics to reduce wind noise and incorporates advanced safety features like multiple airbags and stability control systems. As part of the core Mercedes-Benz lineup, the 400 designation is often used for hybrid versions, positioned at the high-end in the luxury market with a typically higher but well-justified price range.

If you're considering the Mercedes-Benz 400 when buying a car, I must remind you that it primarily belongs to the S-Class series, which is the top-tier lineup of Mercedes-Benz. Driving it gives you a great sense of prestige, with outstanding handling and noise insulation. The interior features, such as rear-seat entertainment and large-screen instrument panels, are truly captivating. However, the price is quite high, and it holds its value well in the used car market. For maintenance, it's recommended to regularly visit authorized Mercedes-Benz service centers, as routine oil changes and inspections can reduce the risk of malfunctions. This model reflects Mercedes-Benz's commitment to quality, but don't confuse it with other models like the GLE 400.

The Mercedes-Benz 400 is regarded as a high-end symbol in many cultures. As part of the S-Class lineup, it frequently appears in films and business settings. The driving experience is exceptionally stable, with a refined interior that exudes understated luxury. The Mercedes S-Class has always emphasized reliability and technological innovation, and the 400 model embodies this philosophy, such as with its eco-friendly hybrid powertrain. Although Mercedes offers other series like the E-Class or C-Class in the market, the 400 is most commonly associated with the classic elegance of the S-Class.
