Mercedes-Benz introduced the 260 D in 1936, widely regarded as the first production diesel passenger car.
The 260 D used a 2.6-litre four-cylinder diesel engine and was based on Mercedes-Benz’s Mannheim model. Its diesel engine was designed for durability and fuel economy, qualities that made it particularly attractive for taxi operators and commercial users.
The car appeared before diesel engines became common in passenger vehicles. Early diesel cars were slower and noisier than petrol-powered models, but their lower fuel consumption offered an important operating advantage. Mercedes-Benz continued developing diesel passenger cars, eventually helping make the technology a major part of European motoring.
The 260 D is sometimes confused with later Mercedes-Benz diesel milestones, including the 300 SD, which was the first production turbocharged diesel passenger car. The 260 D’s distinction is earlier: it pioneered series production of diesel-powered passenger cars.
