Powertrain & Engine Architecture
The heart of the E 270 CDI is the OM 647.961, a 2.7-liter inline-five cylinder diesel engine. This engine was a cornerstone of Mercedes-Benz’s diesel offerings in the early 2000s, known for its robust construction and relatively smooth operation for a five-cylinder configuration. The OM 647 featured a cast iron block and aluminum cylinder head, contributing to its durability. It employed a second-generation common rail direct injection system, delivering fuel at extremely high pressures (up to 1600 bar) for optimized combustion and reduced emissions. A variable geometry turbocharger (VGT) with an intercooler further enhanced performance and efficiency. The engine produced 177 horsepower at 4200 rpm and a substantial 400 Nm (295 lb-ft) of torque at just 1800 rpm. The six-speed manual transmission was standard, providing a good balance of fuel economy and driver control. While an automatic transmission was available, the manual was favored by those prioritizing efficiency and a more engaging driving experience.
Driving Characteristics
The E 270 CDI, with its manual transmission, offered a surprisingly capable driving experience. The high torque output of the engine meant strong acceleration from low speeds, making it well-suited for overtaking and navigating city traffic. While not a sports car, the E 270 CDI could reach 60 mph in around 8.8 seconds and achieve a top speed of 138.57 mph. The manual gearbox, while offering more driver involvement, had relatively long throws compared to some competitors. The suspension, tuned for comfort, provided a smooth ride, absorbing bumps and imperfections in the road effectively. Compared to the higher-output E 320 CDI, the E 270 CDI felt less urgent in its acceleration, but it offered significantly better fuel economy. The manual transmission also provided a more direct connection to the engine than the optional automatic.
Equipment & Trim Levels
The E 270 CDI T-modell typically came well-equipped, reflecting Mercedes-Benz’s reputation for luxury. Standard features included automatic climate control, power windows and mirrors, a multi-function steering wheel, and a high-quality audio system. Upholstery was typically a durable fabric, with leather options available as an upgrade. Optional extras included a sunroof, navigation system, heated seats, and parking sensors. The estate body style itself added to the practicality, with a large cargo area that could be expanded by folding down the rear seats. The interior design was typical of the S211 E-Class – functional, elegant, and built to a high standard.
Chassis & Braking
The S211 E-Class featured a robust chassis with coil spring suspension all around. The front suspension utilized MacPherson struts, while the rear employed a multi-link setup, providing a good balance of comfort and handling. The E 270 CDI was equipped with ventilated disc brakes at the front and solid discs at the rear. Anti-lock braking system (ABS) was standard, enhancing safety and stability during braking. The steering was a hydraulic power-assisted rack and pinion system, offering precise and responsive control. The tires were typically 225/55 R16, providing good grip and ride comfort.
Market Reception & Comparison
The E 270 CDI T-modell was generally well-received by automotive critics. It was praised for its fuel efficiency, comfortable ride, and spacious interior. However, some critics noted that the engine could be somewhat noisy compared to some competitors, and the manual transmission’s shift quality wasn’t always the smoothest. Compared to the E 320 CDI, the E 270 CDI offered a more affordable entry point into the E-Class estate range, appealing to buyers who prioritized economy over outright performance. Against rivals like the BMW 5 Series Touring and Audi A6 Avant, the E 270 CDI held its own in terms of refinement and practicality.
Legacy
The OM 647 engine, found in the E 270 CDI, proved to be a durable and reliable powerplant when properly maintained. While early common rail diesel engines were sometimes prone to injector issues, the OM 647 generally proved to be robust. Today, well-maintained examples of the E 270 CDI T-modell are sought after by enthusiasts and those looking for a practical and economical classic. Parts availability remains good, and the relatively simple mechanical design makes it a viable option for DIY mechanics. The E 270 CDI represents a sweet spot in the S211 E-Class range, offering a compelling combination of luxury, practicality, and fuel efficiency.
