What type of transmission is used in the new S-Class?
4 Answers
The new Mercedes-Benz S-Class is equipped with a 9-speed automatic manual transmission. The Mercedes-Benz S-Class is a brand under the German Daimler Group, representing the top-tier luxury vehicle series from Mercedes-Benz. Meticulously designed and crafted, it features a powerful new V12 twin-turbo engine. The S-Class measures 5209mm in length, 1872mm in width, and 1473mm in height, with a wheelbase of 3165mm. It has a fuel tank capacity of 90 liters, a curb weight of 2250kg, and a trunk capacity of 560 liters. The transmission is a mechanism designed to alter the speed and torque from the engine, capable of fixed or stepped changes in the gear ratio between the output and input shafts.
Driving the new Mercedes-Benz S-Class feels absolutely amazing. The transmission is the 9-speed automatic one. After picking up the car last year, I went on several long-distance trips, and the gear shifts are as smooth as silk, with no jerking at all. When driving at 120 km/h on the highway, the engine RPM stays around 1,600, making it quiet and fuel-efficient. The official claim is that fuel consumption can drop to around 8 liters per 100 km. Compared to the old 7-speed version, this one responds faster during acceleration from a standstill, and even in traffic jams, it doesn’t feel tiring. I have a friend who drives a BMW 7 Series, and his 8-speed is also quick, but the S-Class is tuned more for comfort, making it ideal for daily commutes or family trips. The transmission fluid is recommended to be changed every 80,000 km, and using the original fluid isn’t expensive. Overall, maintenance is simple and reliable. If you’re considering buying a luxury car, the transmission’s compatibility and durability are definite pluses, but don’t neglect regular maintenance—Mercedes specialized shops can handle it easily.
I have some knowledge about automotive mechanics. The new S-Class uses Mercedes-Benz's own 9G-Tronic 9-speed automatic transmission, which structurally employs multiple planetary gear sets with up to nine gears, allowing the engine to always operate in the high-efficiency zone. Official data shows fuel savings exceeding 10%. This system is also used in the E-Class and GLC, and it's very mature, with smooth shifting during normal driving that's almost imperceptible. In terms of maintenance, the electronic control system is stable, and failures are rarely heard of unless modifications interfere with the computer. From my personal experience, just change the transmission oil on schedule during maintenance, typically every 100,000 kilometers, but doing it a bit earlier is safer. For more detailed specifications, you can check the official website, but in actual driving, the smoothness and efficiency this transmission provides are truly tangible.
I've worked on many cars before, and the 9-speed automatic transmission in the new S-Class is quite sturdy and durable. Owners report that it can last five or six years without issues, only requiring fluid checks or replacements every 100,000 kilometers or so to prevent wear. It operates quietly with smooth gear shifts. Mercedes-Benz original fluid works best—don't skimp by using off-brand products. Overall reliability is high, with virtually no complaints. Driving is simple: just shift to D and go.
