Powertrain & Engine Architecture
The heart of the E 320 CDI T-modell was the OM 642.920 3.0-liter V6 turbodiesel engine. This engine was a significant advancement in Mercedes-Benz’s diesel technology, featuring common-rail direct injection, a variable geometry turbocharger, and an intercooler. The common-rail system, operating at extremely high pressures, allowed for precise fuel metering and optimized combustion, resulting in improved power, efficiency, and reduced emissions. The V6 configuration provided inherent smoothness and refinement compared to inline engines. The engine produced 224 horsepower at 3800 rpm and a substantial 540 Nm (398 lb-ft) of torque between 1600 and 2400 rpm. This torque output was a key characteristic, providing strong acceleration and effortless cruising. Paired with the engine was the 7G-TRONIC seven-speed automatic transmission. This transmission offered smooth, quick shifts and contributed to both performance and fuel economy. The 7G-TRONIC allowed the engine to operate in its optimal power band more frequently, enhancing responsiveness.
Driving Characteristics
The E 320 CDI T-modell offered a refined and comfortable driving experience. The abundant torque meant that strong acceleration was available from low engine speeds, making overtaking and merging onto highways effortless. While not a sports car, the E 320 CDI provided ample power for spirited driving. The 7G-TRONIC transmission contributed to a seamless driving experience, with minimal shift shock. Compared to the E 220 CDI, the E 320 CDI offered a noticeable performance improvement, while the higher-output E 500 provided significantly more power but at the expense of fuel economy. The rear-wheel-drive configuration provided a balanced feel, although it could be less confident in slippery conditions compared to all-wheel-drive variants available in other E-Class models.
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, parking sensors, and adaptive cruise control. The facelift models benefited from improved interior materials and a more modern dashboard design. Trim levels varied slightly depending on the market, but generally, the E 320 CDI represented a well-appointed and comfortable vehicle.
Chassis & Braking
The S211 E-Class featured a double wishbone front suspension and an independent multi-link rear suspension, providing a comfortable ride and good handling characteristics. Stabilizer bars were fitted front and rear to reduce body roll. The E 320 CDI T-modell was equipped with disc brakes on all four wheels, providing ample stopping power. Anti-lock braking system (ABS) was standard, enhancing safety. The suspension was tuned to prioritize comfort, but still offered a reasonably controlled driving experience. The weight distribution was generally well-balanced, contributing to stable handling.
Market Reception & Comparison
The E 320 CDI T-modell was generally well-received by automotive critics. It was praised for its powerful and efficient engine, comfortable ride, and spacious interior. The combination of diesel economy and V6 performance was particularly appealing to buyers who frequently covered long distances. Compared to the E 220 CDI, the E 320 CDI offered a significant performance upgrade, justifying the higher price. Fuel economy was a strong point, with combined figures ranging from 7.6 to 8.1 liters per 100 kilometers (30.9 to 29 US mpg). Reliability was generally good, although diesel particulate filter (DPF) issues could occur with infrequent long-distance driving.
Legacy
The OM 642 engine family, including the OM 642.920 found in the E 320 CDI, has proven to be remarkably durable. With proper maintenance, these engines can reliably exceed 200,000 miles. The 7G-TRONIC transmission is also generally reliable, although fluid changes are crucial for longevity. Today, the S211 E 320 CDI T-modell represents a compelling value on the used car market. It offers a unique combination of luxury, practicality, and fuel efficiency that is difficult to find in more modern vehicles. However, potential buyers should be aware of potential issues with the DPF and ensure that the vehicle has been properly maintained.
