Powertrain & Engine Architecture
The E 250 CDI was powered by the OM 651.911, a 2.1-liter inline-four cylinder diesel engine. This engine was a mainstay of the Mercedes-Benz lineup, known for its robust construction and efficiency. The OM651 featured a cast iron block and aluminum cylinder head, contributing to its durability. It employed a sophisticated common-rail direct injection system, delivering fuel at extremely high pressures for optimized combustion. Crucially, this engine utilized a bi-turbocharger setup – a smaller turbocharger for quick response at low engine speeds and a larger turbocharger for increased power at higher RPMs. An intercooler further enhanced performance by cooling the compressed intake air. The engine’s valvetrain consisted of a double overhead camshaft (DOHC) design with four valves per cylinder, maximizing airflow and contributing to its power output. The 6-speed manual transmission was standard, providing precise gear changes and a more engaging driving experience compared to the optional automatic.
Driving Characteristics
The E 250 CDI Coupe, with its 204 horsepower and 368 lb-ft of torque, offered a relaxed yet capable driving experience. While not overtly sporty, the engine provided ample power for comfortable highway cruising and confident overtaking maneuvers. The torque curve was particularly strong, delivering readily available power from as low as 1600 rpm. The 6-speed manual transmission allowed drivers to fully exploit the engine’s capabilities, although the gear ratios were tuned more for fuel efficiency than outright acceleration. Compared to the E 350 CDI, the E 250 CDI offered less peak power, resulting in slightly slower acceleration (0-60 mph in approximately 7 seconds versus the E 350 CDI’s 5.4 seconds). However, the E 250 CDI’s lighter weight and more efficient engine contributed to superior fuel economy.
Equipment & Trim Levels
The E 250 CDI Coupe came reasonably well-equipped as standard. Interior features typically included leather upholstery, automatic climate control, a multi-function steering wheel, and a high-quality audio system. The dashboard layout was elegant and functional, with a focus on user-friendliness. Optional extras included a panoramic sunroof, upgraded audio systems (such as Harman Kardon), navigation system, parking assist, and various driver assistance features like lane keeping assist and blind spot monitoring. Exterior options included different wheel designs, metallic paint finishes, and various styling packages.
Chassis & Braking
The C207 E-Class Coupe featured a sophisticated chassis designed to balance comfort and handling. The front suspension utilized a coil spring, independent multi-link setup with a transverse stabilizer bar, while the rear suspension employed an independent multi-link spring suspension, also with a stabilizer bar. This configuration provided a comfortable ride while minimizing body roll during cornering. Braking duties were handled by ventilated discs at the front and solid discs at the rear, providing adequate stopping power. Anti-lock braking system (ABS) was standard, enhancing safety and stability. The steering system was a rack and pinion setup with electric power steering, offering precise control and a comfortable steering feel.
Market Reception & Comparison
The E 250 CDI Coupe was generally well-received by automotive critics. It was praised for its fuel efficiency, comfortable ride, and refined interior. However, some reviewers noted that the engine, while capable, lacked the outright performance of its larger counterparts. Compared to the E 220 CDI, the E 250 CDI offered a noticeable power upgrade, making it a more appealing option for drivers who frequently undertook long journeys or desired more responsive acceleration. Against the E 350 CDI, the E 250 CDI represented a more economical choice, sacrificing some performance in exchange for significantly improved fuel economy.
Legacy
The OM 651 engine, found in the E 250 CDI, has proven to be remarkably durable and reliable. With proper maintenance, these engines can easily exceed 200,000 miles. The C207 E-Class Coupe, including the E 250 CDI variant, has maintained a solid reputation in the used car market. Its combination of luxury, fuel efficiency, and reliability makes it an attractive option for buyers seeking a sophisticated and practical coupe. However, potential buyers should be aware of the potential for diesel particulate filter (DPF) issues, particularly on vehicles that have primarily been used for short trips. Regular servicing and the use of high-quality diesel fuel are essential for maintaining the long-term health of this powertrain.
