Powertrain & Engine Architecture
The heart of the E 320 CDI T-modell is the OM 642.920 3.0-liter V6 diesel engine. This engine is a robust and technologically advanced design, featuring a common rail direct injection system, a variable geometry turbocharger, and an intercooler. The common rail system, operating at extremely high pressures, allows for precise fuel metering and optimized combustion, contributing to both power and efficiency. The engine boasts four valves per cylinder and a double overhead camshaft (DOHC) configuration, further enhancing its breathing and performance. The 17.7:1 compression ratio is typical for a diesel engine, aiding in efficient combustion. Paired with this engine is the 7G-TRONIC seven-speed automatic transmission. This transmission, a hallmark of Mercedes-Benz engineering, provides smooth and responsive gear changes, contributing to a refined driving experience. It features a torque converter lockup clutch to improve fuel economy at cruising speeds.
Driving Characteristics
The E 320 CDI T-modell delivers a strong and refined driving experience. The 224 horsepower and 510 Nm (376 lb-ft) of torque provide ample power for both everyday driving and longer journeys. Acceleration from 0 to 60 mph takes approximately 6.9 seconds, which is respectable for a large station wagon. The 7G-TRONIC transmission is well-matched to the engine’s characteristics, providing seamless gear changes and keeping the engine in its optimal power band. Compared to the gasoline-powered E 320 variants, the CDI offers significantly better fuel economy and a broader torque curve, making it more effortless to drive in most situations. While not as sporty as some of the higher-performance E-Class models, the E 320 CDI provides a comfortable and capable driving experience.
Equipment & Trim Levels
The E 320 CDI T-modell typically came well-equipped as standard. Features included automatic climate control, power-adjustable front seats, a multi-function steering wheel, and a high-quality audio system. Interior upholstery was typically a combination of leather and fabric, with options for full leather available. Optional extras included a sunroof, navigation system, premium sound system, and parking sensors. The S211 E-Class offered a range of customization options, allowing buyers to tailor the vehicle to their specific preferences.
Chassis & Braking
The S211 E-Class T-modell features a sophisticated chassis design. The front suspension utilizes a coil spring, double wishbone setup with a transverse stabilizer, providing good handling and ride comfort. The rear suspension is an independent multi-link design, also with a transverse stabilizer, further enhancing ride quality and stability. Ventilated disc brakes are fitted to all four wheels, providing ample stopping power. Anti-lock Braking System (ABS) is standard, enhancing safety and control during emergency braking situations. Air suspension was available as an option, providing an even more comfortable and controlled ride.
Market Reception & Comparison
The E 320 CDI T-modell was generally well-received by automotive critics. It was praised for its powerful and efficient diesel engine, comfortable ride, and spacious interior. Compared to the gasoline-powered E 320, the CDI offered superior fuel economy and torque, making it a more practical choice for many buyers. However, some critics noted that the diesel engine was slightly noisier than the gasoline counterpart. In terms of reliability, the OM 642 engine is generally considered to be a durable and long-lasting unit, although regular maintenance is essential.
Legacy
The Mercedes-Benz E 320 CDI T-modell (S211) remains a desirable used car today. Its combination of practicality, luxury, and fuel efficiency continues to appeal to buyers. The OM 642 engine, when properly maintained, is known for its longevity and reliability. However, potential buyers should be aware of the potential for issues with the diesel particulate filter (DPF) and the glow plug system. Overall, the E 320 CDI T-modell represents a well-engineered and refined station wagon that offers a compelling alternative to more modern vehicles.
