The Mercedes-Benz E-Class Long (V214) E 260, introduced in December 2023, represents a significant iteration of the iconic E-Class sedan, specifically tailored for markets prioritizing rear passenger space, such as China. Positioned as a mid-range offering within the V214 lineup, the E 260 combines a 2.0-liter turbocharged inline-four engine with a 48-volt mild hybrid system and a 9G-TRONIC automatic transmission. This configuration aims to balance performance, efficiency, and refinement, appealing to buyers seeking a comfortable and technologically advanced luxury vehicle. The “Long” designation indicates an extended wheelbase, adding approximately 150mm to the standard E-Class, resulting in increased legroom for rear occupants.

Powertrain & Engine Architecture
The E 260 utilizes the M 254.920 engine, a 2.0-liter inline-four cylinder gasoline engine. This engine benefits from direct fuel injection and a twin-scroll turbocharger, contributing to both power output and efficiency. The CAMTRONIC variable valve timing system further optimizes engine performance across a wider range of operating conditions. The 48-volt mild hybrid system integrates a belt-driven starter-generator (BSG) that provides functions like regenerative braking, extended start-stop operation, and a small power boost during acceleration. The 9G-TRONIC nine-speed automatic transmission is a key component, offering smooth and efficient gear changes. This transmission is known for its wide gear ratio spread, contributing to both fuel economy and responsive acceleration.
Driving Characteristics
The E 260 delivers a refined and comfortable driving experience. While not overtly sporty, the 204 horsepower and 320 Nm (236 lb-ft) of torque provide adequate performance for everyday driving situations. The 0-60 mph time of around 7.3 seconds is respectable for a luxury sedan of this size. The 9G-TRONIC transmission is programmed for smooth shifts, prioritizing comfort over aggressive gear changes. Compared to higher-output E-Class variants like the E 350, the E 260 offers a more relaxed driving experience. The mild hybrid system provides a subtle but noticeable boost during acceleration, and the extended start-stop functionality contributes to improved fuel economy in city driving. The rear-wheel drive configuration provides a balanced feel, although all-wheel drive (4MATIC) is available as an option.
Equipment & Trim Levels
The E 260 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, advanced driver-assistance systems (such as adaptive cruise control and lane keeping assist), a panoramic sunroof, and upgraded audio systems. Trim levels beyond the base E 260 may offer additional cosmetic enhancements and exclusive features.
Chassis & Braking
The V214 E-Class Long utilizes a sophisticated chassis design. The front suspension features a multi-link setup with coil springs, while the rear suspension also employs a multi-link design. Air suspension is available as an option, providing an even more comfortable ride and the ability to adjust ride height. The E 260 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. Steering is rack-and-pinion with electric power assistance.
Market Reception & Comparison
The E 260 has been generally well-received by automotive critics, particularly for its comfortable ride, refined interior, and advanced technology. Its fuel economy of around 38.2 US mpg is competitive within the luxury sedan segment. Compared to other E-Class variants, the E 260 offers a more affordable entry point into the range, making it an attractive option for buyers who prioritize comfort and efficiency over outright performance. The mild hybrid system contributes to improved fuel economy and reduced emissions compared to non-hybrid E-Class models. Reliability reports are still emerging for the V214 generation, but Mercedes-Benz has a generally good reputation for build quality and durability.
Legacy
The E 260, as part of the V214 E-Class Long, represents a continuation of Mercedes-Benz’s commitment to luxury, innovation, and refinement. The combination of a turbocharged engine, mild hybrid technology, and a sophisticated automatic transmission positions it as a modern and efficient luxury sedan. Its long-term reliability remains to be seen, but the M 254 engine family has proven to be relatively robust in other Mercedes-Benz models. On the used car market, the V214 E 260 is expected to hold its value well, appealing to buyers seeking a comfortable, well-equipped, and technologically advanced luxury vehicle.
