2020-2023 Mercedes-Benz E-class T-modell (S213 facelift ) E 300de (306 Hp) Plug-in Hybrid 9G-TRONIC

The Mercedes-Benz E 300 de T-modell (S213, facelift 2020) represents a compelling blend of diesel efficiency and electric driving capability within the E-Class wagon range. Introduced in July 2020 and remaining in production through 2023, this plug-in hybrid variant was positioned as a premium offering, bridging the gap between traditional diesel E-Class models and the fully electric EQ range. It’s built on the W213 E-Class platform, benefitting from the 2020 facelift which brought updated styling, technology, and powertrain refinements. The “de” designation signifies “Diesel Electric,” highlighting the core powertrain strategy.

Technical Specifications

Powertrain & Engine Architecture

The E 300 de’s powertrain centers around the OM 654.920 2.0-liter inline-four diesel engine, coupled with a 122 hp electric motor integrated between the engine and the 9G-TRONIC nine-speed automatic transmission. The diesel engine utilizes a common-rail direct injection system and a turbocharger with intercooling, producing 194 hp and 400 Nm of torque. The electric motor contributes an additional 122 hp and 440 Nm of torque, resulting in a combined system output of 306 hp and 700 Nm. The 13.5 kWh lithium-ion battery pack, located under the trunk floor, provides an all-electric range of 44-55 km (27-34 miles) under WLTP testing. The 9G-TRONIC transmission is specifically calibrated to work seamlessly with the electric motor, offering smooth transitions between electric, hybrid, and combustion engine power.

Driving Characteristics

The E 300 de offers a remarkably refined driving experience. In electric mode, it provides near-silent acceleration and sufficient power for urban driving. When the diesel engine engages, the transition is almost imperceptible. The combined output delivers strong acceleration, achieving 0-60 mph in approximately 5.7 seconds. The 9G-TRONIC transmission’s wide gear ratios help optimize fuel efficiency and provide responsive shifts. Compared to the petrol-powered E 300, the E 300 de offers superior torque and fuel economy, while the all-electric range provides a significant advantage for short commutes. Compared to the E 300d (diesel only), the plug-in hybrid offers the benefit of emissions-free driving for shorter distances.

Equipment & Trim Levels

The E 300 de T-modell typically came well-equipped, reflecting its premium positioning. Standard features included Mercedes-Benz’s MBUX infotainment system with a large touchscreen display, leather upholstery, heated front seats, automatic climate control, and a suite of driver-assistance systems such as adaptive cruise control and lane-keeping assist. Optional extras included a panoramic sunroof, premium sound system, and advanced parking assistance features. Interior trim options varied, allowing buyers to personalize the cabin to their preferences.

Chassis & Braking

The E 300 de T-modell utilizes a sophisticated chassis setup. It features a four-link front suspension and a multi-link rear suspension, often incorporating air suspension for enhanced ride comfort. Ventilated disc brakes are fitted on all four wheels, providing ample stopping power. The increased weight due to the battery pack is managed by the upgraded suspension components. Standard safety features include ABS, ESP, and a range of airbags.

Market Reception & Comparison

The E 300 de was generally well-received by automotive critics, praised for its fuel efficiency, refined driving experience, and practicality. Its ability to operate in all-electric mode was a significant selling point, particularly in urban environments. Compared to other E-Class variants, the E 300 de offered a unique combination of performance and economy. While the initial purchase price was higher than the diesel-only models, the potential fuel savings and tax benefits made it an attractive option for many buyers.

Legacy

The Mercedes-Benz E 300 de T-modell represents an important step in the brand’s transition towards electrification. The OM 654 diesel engine, combined with the plug-in hybrid technology, proved to be a reliable and efficient powertrain. On the used car market, these models are sought after for their versatility and low running costs. The longevity of the battery pack remains a key consideration for potential buyers, but well-maintained examples continue to offer a compelling blend of luxury, practicality, and environmental responsibility.
