The Mercedes-Benz W124 300 E, produced from April 1984 to September 1985, represents a pivotal moment in the German automaker’s history. This mid-size sedan, part of the W124 series, was designed to replace the W201 (190E) and W123 models, offering a blend of luxury, performance, and engineering that set a new standard for its class. The 300 E, specifically, was positioned as a premium offering within the range, boasting a larger engine and enhanced features compared to its lower-spec counterparts. The W124 series, known for its robust build quality and longevity, quickly gained a reputation for reliability and became a popular choice among discerning buyers, particularly in Europe where it was a common sight on the autobahn.
The Mercedes-Benz W124 300 E: A Legacy of Engineering
The W124 series was a significant departure from previous Mercedes-Benz designs, incorporating advancements in safety, aerodynamics, and overall refinement. The 300 E, with its 190 horsepower engine, was a performance-oriented version of the W124, aimed at drivers who appreciated a more spirited driving experience. It was a car built to cover long distances in comfort and style, embodying the traditional Mercedes-Benz values of quality and durability. The W124’s design language, characterized by its clean lines and understated elegance, remains influential even today.
Engine & Performance
At the heart of the 300 E lies the M103 E 30 inline-six cylinder engine, a 2,962 cc (180.75 cu. in.) naturally aspirated powerplant. This engine, producing 190 horsepower at 5,600 rpm and 260 Nm (191.77 lb.-ft.) of torque at 4,250 rpm, provided a smooth and responsive driving experience. The engine featured multi-port manifold fuel injection and a single overhead camshaft (SOHC) valvetrain. The 300 E could accelerate from 0 to 60 mph in approximately 7.5 seconds and achieve a top speed of 230 km/h (142.92 mph). The engine’s longitudinal front-engine layout and rear-wheel drive configuration contributed to its balanced handling characteristics. Fuel economy was rated at 12.1 l/100 km (19.4 US mpg) in urban conditions and 6.5 l/100 km (36.2 US mpg) on the open road.
Design & Features
The W124 300 E is a four-door sedan with a spacious interior capable of comfortably seating five passengers. Its body design prioritized both aesthetics and aerodynamics, resulting in a sleek and modern appearance for its time. The car’s robust construction and attention to detail were hallmarks of Mercedes-Benz engineering. Key features included ventilated disc brakes on the front wheels and disc brakes on the rear, providing ample stopping power. An Anti-lock Braking System (ABS) was also included, enhancing safety and control. The suspension system utilized wishbones at the front and an independent multi-link setup with coil springs at the rear, delivering a comfortable and controlled ride. Power steering, utilizing a cone worm and recirculation balls system, made maneuvering the vehicle effortless. The 300 E came equipped with 195/65 R15 tires on 6.5J x 15 inch wheel rims.
