🔍 Model Background

The Mercedes 300 D 2.5 Turbo (1990–1993) was a refined evolution of the W124 diesel lineup, blending modern styling and advanced engineering with the legendary longevity of Mercedes-Benz diesel powertrains. It offered improved performance and efficiency while maintaining the durability that made its predecessors icons.

At its heart was the 2.5-liter OM602.962 inline-five turbo-diesel engine, producing around 121 horsepower and 165 lb-ft of torque. Mated to a 4-speed automatic transmission, this engine featured a smaller displacement and a turbocharger, delivering smoother acceleration, improved fuel economy, and lower emissions compared to earlier models.

Built on the sophisticated W124 platform, the 300 D 2.5 Turbo featured independent front and rear suspension, ABS brakes, and a rigid chassis that offered a balanced combination of ride comfort, safety, and handling precision. It was a standout for its quiet diesel operation and refined driving dynamics.

The interior reflected Mercedes’ focus on quality and ergonomics, with premium materials, real wood trim, supportive seating, and available leather upholstery. Features such as power windows, climate control, and cruise control made it a comfortable and capable long-distance cruiser.

Today, the Mercedes 300 D 2.5 Turbo is appreciated for its blend of efficiency, reliability, and understated luxury. It remains a popular choice among enthusiasts who value the timeless design and engineering excellence of the W124 chassis, especially in its diesel configurations.
