Description
The Mercedes-Benz 240 TD Automatic was the diesel estate variant of the W123 range, combining Mercedes-Benz’s legendary diesel durability with the practicality of the T-Modell body and the ease of an automatic transmission. Introduced in the late 1970s, it was aimed at buyers who needed space and comfort for long-distance use rather than performance, and it quickly earned a reputation as one of the most dependable family and professional vehicles of its era.
Power came from the 2.4-litre inline four-cylinder diesel engine, producing approximately 65 horsepower. While modest in output, this engine delivered strong low-end torque and exceptional fuel economy. When paired with the three-speed automatic transmission, acceleration was leisurely, but progress was smooth and consistent. The drivetrain was engineered for longevity and reliability, making the 240 TD Automatic particularly well suited to steady cruising, towing and fully loaded operation over long distances.
A defining feature of the 240 TD was its estate-specific chassis setup. In addition to the standard W123 suspension layout of double wishbones at the front and a semi-trailing arm rear axle, the T-Modell was fitted with hydropneumatic self-levelling rear suspension as standard. This system automatically maintained correct ride height regardless of load, ensuring stable handling and braking even when the car was heavily laden. Disc brakes at all four wheels provided dependable stopping power appropriate to the vehicle’s weight and intended use.
Styling followed the clean, functional design language of the W123 range. The long roofline, near-vertical tailgate and large glass area maximised interior space and visibility, while restrained chrome detailing preserved a professional and understated appearance. Externally, there was little to distinguish the automatic version from the manual, reinforcing Mercedes-Benz’s philosophy that comfort and engineering sophistication did not need visual emphasis.
Inside, the cabin was practical, spacious and built to exceptional durability standards. Seating was firm and supportive, designed for long periods behind the wheel, and interior materials were chosen for wear resistance rather than luxury. The rear load area was flat, wide and easy to access, making the car suitable for family use, professional duties or long holidays. With the rear seats folded, the 240 TD offered impressive cargo capacity while retaining the comfort of an executive saloon.
In everyday use, the Mercedes-Benz 240 TD Automatic excelled as a calm and dependable long-distance vehicle. It rewarded smooth, patient driving and mechanical sympathy rather than speed. The automatic transmission reduced driver effort in traffic and urban environments, while the diesel engine’s economy and resilience made running costs low for a vehicle of its size. These qualities made it especially popular with families, taxi operators and owners who covered high annual mileages.
Production numbers of the automatic diesel estates were lower than their manual counterparts, as most diesel buyers preferred manual gearboxes for performance and economy. As a result, the 240 TD Automatic was relatively uncommon even when new, and many examples were worked hard throughout their lives, contributing to the scarcity of well-preserved cars today.
Today, the Mercedes-Benz 240 TD Automatic is regarded as a classic example of Mercedes-Benz engineering at its most pragmatic. Valued for its durability, load-carrying ability and relaxed driving character, it represents an era when estate cars were built to serve reliably for decades. As a W123 diesel T-Modell with automatic comfort, it stands as a benchmark for longevity, practicality and understated quality.
