The Mercedes-Benz 300 CD, produced from 1978 to 1981, was a luxurious and powerful coupe that embodied the brand's reputation for engineering excellence and sophisticated design. This iteration of the 300 series was a notable departure from its predecessors, featuring a sleeker, more aerodynamic body style that emphasized its sporting character. The 300 CD was powered by a 3.0-liter inline-six diesel engine, a deviation from the gasoline engines commonly found in other 300 models. This innovative powertrain, coupled with a five-speed manual transmission, delivered a remarkable combination of fuel efficiency and robust performance. Its smooth yet powerful demeanor, paired with a spacious and comfortable interior, made the 300 CD a desirable choice for discerning drivers who appreciated both performance and refinement.

Its spacious cabin offered generous legroom and headroom for both driver and passengers, while its luxurious features included plush leather seats, air conditioning, and a sophisticated sound system. The 300 CD's aerodynamically sculpted body, with its distinctive sloping roofline and integrated rear spoiler, not only contributed to its sleek aesthetic but also enhanced its handling and fuel economy. Its robust diesel engine provided ample torque for effortless acceleration and confident cruising, while its five-speed manual gearbox offered precise and engaging control. The 300 CD, therefore, was a well-rounded machine that appealed to a wide range of drivers, from those who sought a stylish and comfortable cruiser to those who desired a powerful and efficient performance vehicle.
