The Mercedes-Benz E-Class Long (V214) E 260 4MATIC, introduced in March 2024, represents a significant iteration of the iconic E-Class sedan, specifically tailored for markets prioritizing rear passenger space. This variant, powered by a 2.0-liter turbocharged inline-four engine coupled with a mild hybrid system and a 9G-TRONIC automatic transmission, occupies a key position in the E-Class lineup as a balance between performance, efficiency, and luxury. The “Long” designation indicates an extended wheelbase, offering increased legroom for rear occupants, making it particularly popular in markets like China where chauffeur-driven vehicles are common. This model is positioned as a step up from the base E 200, offering more power and standard features, while remaining more accessible than the higher-performance E 300 or E 450 models.

Powertrain & Engine Architecture
The heart of the E 260 4MATIC is the M 254.920 2.0-liter inline-four cylinder engine. This engine utilizes direct fuel injection and a twin-scroll turbocharger to deliver a balance of power and efficiency. The CAMTRONIC variable valve timing system optimizes engine performance across a wide range of operating conditions. Crucially, this engine incorporates a 48-volt mild hybrid system. This system features an integrated starter-generator (ISG) that provides power assist during acceleration, allows for smoother start/stop operation, and enables regenerative braking to recoup energy. The 9G-TRONIC nine-speed automatic transmission is a key component, offering smooth and efficient gear changes. The transmission is designed to work seamlessly with the mild hybrid system, optimizing fuel economy and responsiveness. The engine produces 204 horsepower at 5800 rpm and 320 Nm (236 lb-ft) of torque between 1600 and 4000 rpm.
Driving Characteristics
The E 260 4MATIC offers a comfortable and refined driving experience. The mild hybrid system provides a noticeable boost during acceleration, masking some of the limitations of the 2.0-liter engine. While not as overtly sporty as the E 300 or E 450, the E 260 delivers adequate performance for everyday driving, with a 0-60 mph time of around 7.6 seconds. The 9G-TRONIC transmission contributes to smooth gear changes and helps keep the engine in its optimal power band. The 4MATIC all-wheel-drive system provides excellent traction in various weather conditions. Compared to a manual transmission equipped E-Class (not typically offered with this engine), the 9G-TRONIC prioritizes comfort and ease of use over outright driver engagement. The gear ratios are tuned for fuel efficiency and smooth cruising, rather than aggressive acceleration.
Equipment & Trim Levels
The E 260 4MATIC typically comes well-equipped with standard features including Mercedes-Benz User Experience (MBUX) infotainment system with a large touchscreen display, premium upholstery (often MB-Tex or leatherette), automatic climate control, and a comprehensive suite of safety features. Optional extras include leather upholstery, a panoramic sunroof, advanced driver-assistance systems (such as adaptive cruise control and lane-keeping assist), and upgraded audio systems. Trim levels often vary by market, but generally offer packages that bundle popular options together. The extended wheelbase provides significantly more rear legroom compared to the standard E-Class, enhancing the comfort for rear passengers.
Chassis & Braking
The V214 E-Class utilizes a sophisticated chassis design featuring a multi-link suspension at both the front and rear. The suspension is tuned for a balance of comfort and handling. Air suspension is available as an option, further enhancing ride quality and allowing for adjustable ride height. The E 260 4MATIC is equipped with ventilated disc brakes on all four wheels, providing ample stopping power. Anti-lock braking system (ABS) and electronic stability control (ESC) are standard safety features. The steering system is a rack-and-pinion setup with electric power steering, offering precise and responsive steering feel.
Market Reception & Comparison
The E 260 4MATIC has been generally well-received by automotive critics, praised for its comfortable ride, refined interior, and fuel efficiency. Its fuel economy of around 35.9 US mpg combined is competitive within its segment. Compared to the E 300, the E 260 offers a more affordable entry point into the E-Class range, albeit with slightly less power. The E 200, the base model, offers even greater affordability but lacks the performance and features of the E 260. Reliability reports are still emerging for the V214 generation, but Mercedes-Benz has a generally good reputation for build quality and durability.
Legacy
The M 254 engine family, including the version found in the E 260 4MATIC, is expected to be a mainstay in the Mercedes-Benz lineup for years to come. The combination of turbocharging, direct injection, and mild hybrid technology represents a significant step towards greater efficiency and reduced emissions. The long-wheelbase E-Class variant, particularly in markets like China, is likely to remain a popular choice for those seeking a luxurious and spacious sedan. The 9G-TRONIC transmission has proven to be a reliable and efficient unit, and its continued use in future Mercedes-Benz models is anticipated. As the V214 generation ages, the E 260 4MATIC is expected to hold its value well, appealing to buyers seeking a well-equipped and comfortable luxury sedan.
