🔍 Model Background

The Mercedes 300 SD Turbo (1981–1985) was a landmark in automotive history as the first turbocharged diesel passenger car sold in North America. Built on the W126 S-Class platform, the 300 SD offered a unique combination of luxury, efficiency, and legendary Mercedes-Benz diesel durability.

Under the hood was the 3.0-liter OM617.951 inline-five turbo-diesel engine, producing approximately 120 horsepower and 170 lb-ft of torque. Though not quick by modern standards, the engine was famed for its longevity, smooth operation, and excellent fuel economy, often surpassing 30 mpg on the highway. It was paired with a 4-speed automatic transmission.

The W126 chassis featured independent suspension, four-wheel disc brakes, and advanced safety systems for the time, such as ABS (on later models). While performance was modest, the ride quality, build integrity, and long-distance comfort were exceptional.

Inside, the 300 SD was equipped with high-quality materials, wood trim, supportive seats, and features like power windows, automatic climate control, and cruise control. The quiet, well-insulated cabin made it a relaxing highway cruiser, especially popular among long-distance drivers and diesel enthusiasts.

Today, the Mercedes 300 SD Turbo is celebrated as a milestone in diesel engineering and a symbol of Mercedes-Benz’s durability-first philosophy. Well-maintained examples continue to serve reliably decades later, making them a favorite among collectors and fans of vintage diesel luxury sedans.
