What transmission does the Mercedes-Benz E-Class use?
3 Answers
The Mercedes-Benz E-Class uses a 9-speed automatic transmission with manual mode. Introduction to transmissions: A transmission consists of a gear transmission mechanism and a control mechanism. It has evolved from manual transmissions in the past to continuously variable transmissions (CVT) today, enabling the engine to achieve lower fuel consumption while operating at higher power outputs. The transmission can alter the vehicle's rotational speed and expand the driving wheel's torque and rotation speed. Classification of transmissions: Automatic transmissions have become mainstream internationally, primarily including AT, AMT, CVT, and DCT types. Early AT transmission systems mainly used 4-speed configurations. AT transmissions achieve gear shifting through electronically controlled automatic operating systems. CVT is a true continuously variable transmission with fewer components and a compact size. DCT features dual clutches.
As someone who has been closely following automotive technology for a long time, I always enjoy delving into the details. The most common transmission found in the Mercedes-Benz E-Class is the 9G-TRONIC automatic transmission, which has been widely used since its introduction by Mercedes in 2013. Featuring nine forward gears and a torque converter design, this transmission delivers exceptionally smooth shifting with almost no noticeable jerkiness—whether you're navigating city streets or cruising on the highway, the experience remains seamless. I've tested its performance in daily driving scenarios: quick acceleration response and impressive fuel efficiency, thanks to the multiple gears optimizing engine RPM. For instance, at 70 km/h, the engine operates at a very low RPM, helping save fuel. It also adapts intelligently to Mercedes' various driving modes, such as Comfort or Sport, automatically adjusting shift strategies. Additionally, it's compatible with both rear-wheel-drive and front-wheel-drive versions and boasts solid reliability, reducing maintenance frequency. That said, to ensure long-term health, the transmission fluid should be checked and replaced every 60,000 kilometers. In recent years, Mercedes has also integrated a 48V mild-hybrid system into the E-Class hybrid models, enhancing efficiency—a small but noteworthy innovation.
Having driven the Mercedes-Benz E-Class, I was particularly impressed by its transmission. It's equipped with a 9-speed automatic transmission that shifts incredibly smoothly without any hesitation. Whether in stop-and-go city traffic with quick responses or during high-speed overtaking with seamless power delivery, it never jerks like some manual transmissions. The nine-speed design enhances engine efficiency—maintaining lower RPMs during steady cruising, resulting in quieter operation and better fuel economy. I often find this transmission ideal for long trips, reducing driver fatigue. Paired with Mercedes' Comfort mode, the car starts smoothly with just a slight turn of the steering wheel. It even learns your driving habits—optimizing shift points over time like a personal assistant. Friends who test-drove it agreed it feels silkier than an eight-speed gearbox. However, the AMG high-performance version uses similar hardware but behaves more aggressively in Sport mode, though the standard E-Class is more than sufficient for daily use. I recommend a test drive to experience the difference firsthand—it speaks for itself.
