What are the differences between the Mercedes-Benz E300 and S350?

Below are the differences between the Mercedes-Benz E300 and S350 models in terms of power, wheelbase, and intake method. Details are as follows. Power: The E300 is equipped with a 2.0T 245-horsepower L4 engine, while the S350 features a 3.0T 299-horsepower L6 engine. Wheelbase: The wheelbase of the Mercedes-Benz E300 is 3165mm, whereas the S350 has a wheelbase of 2874mm. Intake Method: There is a difference in the intake method. The E300 uses a turbocharger, while the S350 employs a turbocharger + electric supercharger.

I carefully compared these two models when I changed cars before. The E300 is a Mercedes-Benz mid-to-large-size sedan, while the S350 is a flagship luxury sedan. The S350 measures over 5.3 meters in length, more than 20 cm longer than the E-Class, offering rear legroom spacious enough to stretch out. The interior differences are even more pronounced—the S-Class comes standard with NAPPA leather seats featuring massage functions and a one-piece glass panel for the center console, whereas the E-Class uses regular leather with wood trim. The driving experience also differs: the S350's air suspension filters road bumps as smoothly as silk, while the E300's chassis tuning leans more toward sportiness. The nearly 400,000 RMB price gap mainly reflects these aspects: the S-Class includes high-end features like rear-seat refrigerators, electric sunshades, and night vision systems. The E300 is perfectly adequate for family use, but for business receptions or pursuing a sense of prestige, the S350's presence is undeniably stronger.

Having driven both of my friend's cars, the driving experiences are quite different. The S350 feels like a smooth, steady ship, with its 3.0T six-cylinder engine being almost silent during acceleration, and the 9AT transmission shifting so gently you barely notice. The E300's 2.0T engine is actually sufficient, but the engine noise is noticeably louder when overtaking on the highway. The difference in steering weight is quite interesting: the S350 feels as steady as holding a cup of water when turning in the city, while the E300 is more agile and easier to handle. The noise insulation really highlights the gap—in the S350, you can still have a quiet conversation at 120 km/h, whereas in the E300, wind noise becomes noticeable at just 80 km/h. Surprisingly, the S350 is more fuel-efficient, with its 48V mild hybrid system achieving around 10L/100km in the city. Personally, I think the E300 is more suitable for driving yourself, while the S350 is better suited for hiring a driver.

My research on car configurations reveals the main differences between these two models lie in the details. In terms of electronic systems, the S350 uses the latest MBUX system with AR real-world navigation and fingerprint recognition, while rear passengers can control all vehicle functions via a tablet. The E300 has a slightly smaller screen and less smooth touchpad operation. The gap in safety features is even wider: the S350 comes standard with active lane change assist and rear-wheel steering systems, while these are optional for the E300. The in-car air purification systems also differ, with the S-Class featuring a fragrance generator and real-time PM2.5 monitoring. The lighting systems may appear similar, but the S350's meteor shower headlights can project patterns onto the ground. In reality, the E300 is perfectly adequate for daily use, but spending hundreds of thousands more on the S-Class buys not just a car, but a mobile technology showcase.

From the perspective of resale value and maintenance costs, I would definitely choose the E300. Not to mention the 400,000 yuan price difference for a new car, the annual insurance for the S350 is nearly 10,000 yuan more, and each maintenance service costs over 2,000 yuan more than the E-Class. In the used car market, the E300 retains about 60% of its value after three years, while the S350 drops below 50%. Fuel consumption isn’t a major issue, with both models averaging around 12 liters per 100 km in city commuting. My main concern is repair costs—last time a colleague’s S350 was rear-ended, replacing a taillight cost 28,000 yuan, whereas the same repair for an E300 would only be 8,000 yuan. The price gap for spare parts is also staggering, with a single air suspension unit for the S-Class quoted at over 30,000 yuan. Of course, the S-Class does make a strong impression for business receptions, but for an average family like ours, the E300’s rear seats are more than sufficient, even with two child safety seats installed.
