INTRODUCTION
The W213 E-Class, launched in 2016, marked a significant evolution for Mercedes-Benz’s executive sedan. The E 400 4MATIC, powered by the M276 engine, was a key part of this generation, offering a substantial performance upgrade over the base models. Built on the MRA (Modular Rear-wheel-drive Architecture) platform, the W213 aimed to balance luxury, technology, and driving dynamics. The E 400 4MATIC was produced for a relatively short period, being superseded by updated engine options in later model years. It represented a sweet spot for buyers prioritizing a powerful and comfortable grand touring experience.
Powertrain & Engine Architecture
At the heart of the E 400 4MATIC lies the M276.823 3.0-liter V6 engine. This engine is a 60-degree V6 featuring direct fuel injection and twin turbochargers. The M276 engine family is known for its smooth power delivery and relatively high efficiency. The direct injection system, coupled with the twin-turbo setup, allows for precise fuel control and minimized turbo lag. The engine utilizes a DOHC (Double Overhead Camshaft) valvetrain with four valves per cylinder, optimizing airflow for increased power output. The 9G-TRONIC nine-speed automatic transmission is a crucial component of this powertrain. This transmission offers a wide range of gear ratios, contributing to both fuel efficiency and responsive acceleration. The 9G-TRONIC is known for its smooth shifts and ability to select the optimal gear for any driving situation. The transmission is electronically controlled and adapts to the driver’s style and road conditions.
Driving Characteristics
The E 400 4MATIC delivers a noticeably more engaging driving experience than the E300 models. The 329 horsepower and 354 lb-ft of torque provide ample power for effortless acceleration and confident highway cruising. The 0-60 mph sprint takes just 5.3 seconds, making it a genuinely quick sedan. The 9G-TRONIC transmission plays a vital role in maximizing the engine’s potential, providing smooth and quick gear changes. The 4MATIC all-wheel-drive system ensures excellent traction in all weather conditions, enhancing stability and control. Compared to the E300, the E 400 feels more composed and less strained during aggressive driving. While not as overtly sporty as the AMG variants, the E 400 offers a refined and capable driving experience that appeals to a wider range of drivers. The gear ratios are tuned for a balance between acceleration and fuel economy, with taller gears for relaxed cruising and shorter gears for quick overtaking.
Equipment & Trim Levels
The E 400 4MATIC typically came well-equipped as standard. Key features included leather upholstery, wood trim, a premium sound system, and a comprehensive suite of safety technologies. Standard safety features included automatic emergency braking, lane-keeping assist, and blind-spot monitoring. Optional extras included a panoramic sunroof, upgraded leather options, a head-up display, and advanced driver-assistance systems like Distronic Plus adaptive cruise control. The interior design emphasized luxury and sophistication, with high-quality materials and a modern aesthetic. The dashboard featured a dual 12.3-inch display screen, combining the instrument cluster and infotainment system into a single integrated unit.
Chassis & Braking
The W213 E-Class features a sophisticated suspension system designed to provide a comfortable and controlled ride. The E 400 4MATIC typically came equipped with a multi-link independent suspension at both the front and rear. Air suspension was available as an option, further enhancing ride comfort and allowing for adjustable ride height. The braking system consisted of ventilated discs on all four wheels, providing ample stopping power. The ABS (Anti-lock Braking System) and Electronic Stability Program (ESP) worked in conjunction to maintain control during emergency braking and challenging driving conditions. The 4MATIC all-wheel-drive system distributes power between the front and rear axles as needed, optimizing traction and stability.
Market Reception & Comparison
The E 400 4MATIC was generally well-received by automotive critics. It was praised for its powerful engine, smooth transmission, and comfortable ride. Reviewers noted that it offered a compelling alternative to its rivals, such as the BMW 540i and Audi A6 3.0T. Fuel economy was considered reasonable for a vehicle of its size and performance, averaging around 23 mpg combined. Compared to the E300, the E 400 offered a significant performance boost, but at a higher price point. The E 400 also offered a more refined driving experience than the diesel-powered E350d models. Reliability reports have been generally positive, with few major issues reported.
Legacy
The E 400 4MATIC, while a relatively short-lived variant, has established a reputation as a reliable and enjoyable luxury sedan. The M276 engine is known for its durability, and the 9G-TRONIC transmission has proven to be a robust unit. On the used car market, the E 400 4MATIC commands a premium over the base E300 models, reflecting its superior performance and features. These vehicles are often sought after by buyers who appreciate a blend of luxury, power, and all-weather capability. With proper maintenance, the E 400 4MATIC is expected to provide many years of reliable service, making it a worthwhile investment for discerning buyers.
