Powertrain & Engine Architecture
The heart of the E 300d 4MATIC is the OM 654.820, a 2.0-liter inline-four cylinder diesel engine. This engine is a highly advanced design, featuring a cast iron block, aluminum cylinder head, and a sophisticated commonrail direct injection system operating at extremely high pressures (typically exceeding 2,700 bar). The engine utilizes a sequential twin-turbocharger setup – a small turbocharger for immediate response at low engine speeds, and a larger turbocharger for increased power at higher RPMs. This configuration minimizes turbo lag and provides a broad, usable powerband. The inclusion of EQ Boost, Mercedes-Benz’s 48-volt mild-hybrid system, adds a 20 horsepower electric motor integrated into the powertrain. This system provides several benefits, including smoother start/stop operation, regenerative braking to recapture energy, and a temporary power boost during acceleration. The 9G-TRONIC nine-speed automatic transmission is standard, offering smooth and efficient gear changes. It’s designed to work seamlessly with the engine and EQ Boost system, optimizing fuel economy and performance.
Driving Characteristics
The E 300d 4MATIC delivers a refined and comfortable driving experience. The 265 horsepower and 550 Nm (405.66 lb-ft) of torque provide ample power for effortless cruising and confident overtaking. The EQ Boost system contributes to a noticeable increase in responsiveness, particularly during initial acceleration. The 9G-TRONIC transmission is well-tuned, providing smooth and almost imperceptible gear changes. Compared to the more powerful E 450 models, the E 300d prioritizes fuel efficiency and torque delivery over outright acceleration. While the E 450 offers a more exhilarating driving experience, the E 300d provides a more relaxed and economical option. The 4MATIC all-wheel-drive system ensures excellent traction in all weather conditions, enhancing stability and control. The gear ratios are optimized for both highway cruising and city driving, providing a balance between fuel economy and performance.
Equipment & Trim Levels
The E 300d 4MATIC typically came well-equipped as standard. Features included Mercedes-Benz User Experience (MBUX) infotainment system with a large touchscreen display, leather upholstery, automatic climate control, heated front seats, and a comprehensive suite of safety features such as adaptive cruise control, lane keeping assist, and automatic emergency braking. Optional extras included a premium sound system, panoramic sunroof, head-up display, and various interior trim upgrades. The trim levels offered variations in interior materials, exterior styling elements, and available option packages. The AMG Line package was a popular choice, adding sporty styling cues and upgraded suspension components.
Chassis & Braking
The W213 E-Class features a sophisticated chassis design. The front suspension utilizes a four-link independent setup, while the rear employs a multi-link independent suspension. This configuration provides a comfortable ride and precise handling. The E 300d 4MATIC typically came equipped with ventilated disc brakes on all four wheels, providing ample stopping power. The electronic stability program (ESP) and anti-lock braking system (ABS) are standard features, enhancing safety and control. The suspension tuning is geared towards comfort, but the optional AMG Line package offered a firmer, more sporty ride.
Market Reception & Comparison
The E 300d 4MATIC was generally well-received by automotive critics. It was praised for its refined driving experience, fuel efficiency, and comfortable interior. Critics noted that the mild-hybrid system provided a noticeable improvement in responsiveness and fuel economy. Compared to other E-Class variants, the E 300d offered a compelling balance between performance, efficiency, and price. The 1.8L gasoline variants offered less torque, while the higher-output gasoline models were more expensive. The E 300d’s diesel engine provided superior fuel economy compared to the gasoline options, making it an attractive choice for drivers who prioritize efficiency.
Legacy
The OM 654 engine family, including the version used in the E 300d 4MATIC, has proven to be remarkably reliable. The 9G-TRONIC transmission is also known for its durability. These vehicles, when properly maintained, are expected to provide many years of reliable service. On the used car market, the E 300d 4MATIC holds its value well due to its reputation for quality, efficiency, and comfort. It remains a popular choice for buyers seeking a luxurious and practical sedan with a focus on fuel economy and long-term reliability.
