Powertrain & Engine Architecture
The heart of the E 250 CDI BlueEFFICIENCY is the OM651.911 2.1-liter inline-four cylinder diesel engine. This engine is a highly refined unit, featuring common-rail direct injection and a sophisticated bi-turbocharger system. The two-stage turbocharging – a smaller turbo for quick response at low RPM and a larger turbo for sustained power at higher speeds – contributes to the engine’s broad torque curve. The engine produces 204 horsepower at 4200 rpm and a substantial 500 Nm (368 lb-ft) of torque between 1600 and 1800 rpm. This torque output is a key characteristic, providing strong acceleration without the need for frequent gear changes. The engine also incorporates a particulate filter and a Start & Stop system to enhance fuel efficiency and reduce emissions. Paired with the engine is Mercedes-Benz’s 7G-TRONIC PLUS seven-speed automatic transmission. This transmission is known for its smooth and responsive shifts, contributing to a comfortable driving experience. The transmission’s gear ratios are optimized for both fuel economy and performance, allowing the engine to operate efficiently across a wide range of speeds.
Driving Characteristics
The E 250 CDI Coupe, with its 204 hp and 7G-TRONIC PLUS transmission, delivers a refined and comfortable driving experience. Acceleration from 0 to 60 mph takes approximately 6.9 seconds, which is respectable for a luxury coupe. The engine’s strong low-end torque makes it easy to navigate city traffic and provides effortless overtaking on the highway. While not as overtly sporty as the E 350 CDI, the E 250 CDI offers a good balance between performance and efficiency. The automatic transmission shifts smoothly and intelligently, adapting to driving conditions and driver input. The relatively lower power output compared to higher trims means the engine doesn’t need to be revved aggressively to maintain speed, further contributing to fuel economy. The steering is precise and well-weighted, providing a confident feel on the road.
Equipment & Trim Levels
The E 250 CDI BlueEFFICIENCY typically came well-equipped as standard. Features included automatic climate control, a high-quality audio system, leather upholstery, and a multi-function steering wheel. Optional extras included a panoramic sunroof, upgraded audio systems (such as Harman Kardon), navigation system, parking assist, and various driver assistance systems like lane keeping assist and blind spot monitoring. Interior trim options varied, with choices in wood veneers and aluminum accents. The standard seats offered good support and comfort, and could be upgraded to sport seats for enhanced bolstering.
Chassis & Braking
The C207 E-Class Coupe features a sophisticated chassis designed for both comfort and handling. The front suspension utilizes a multi-link setup with coil springs and a transverse stabilizer bar, while the rear suspension employs an independent multi-link spring suspension, also with a stabilizer bar. This configuration provides a smooth ride and good control in corners. The E 250 CDI typically came equipped with ventilated disc brakes at the front and solid disc brakes at the rear. ABS (Anti-lock Braking System) was standard, providing enhanced braking performance and stability. The steering system is a rack-and-pinion setup with hydraulic power assistance.
Market Reception & Comparison
The E 250 CDI BlueEFFICIENCY was generally well-received by automotive critics. It was praised for its fuel efficiency, comfortable ride, and refined engine. Compared to the E 220 CDI, the E 250 CDI offered a noticeable performance boost without significantly compromising fuel economy. In contrast to the E 350 CDI, it provided a more economical option for buyers who didn’t require the higher levels of performance. Fuel economy figures of around 48-53 mpg (combined) were highly competitive for a vehicle in its class. Reliability was generally good, although, like all modern diesel engines, the particulate filter could require occasional maintenance.
Legacy
The OM651 engine family, including the version found in the E 250 CDI, has proven to be remarkably durable and reliable. Well-maintained examples continue to offer years of dependable service. On the used car market, the E 250 CDI Coupe represents a good value proposition, offering a luxurious and well-equipped coupe at a relatively affordable price point. However, potential buyers should be aware of the potential maintenance costs associated with diesel engines, such as the particulate filter and fuel injectors. Overall, the E 250 CDI BlueEFFICIENCY remains a desirable and capable grand tourer, appreciated for its blend of comfort, efficiency, and refinement.
