1986-1989 Mercedes-Benz S124 300 TE (188 Hp) 4MATIC Automatic

The Mercedes-Benz S124 300 TE (188 Hp) 4MATIC Automatic represents a significant chapter in the history of the W124 generation, a series widely regarded as one of the finest vehicles ever produced by Mercedes-Benz. Introduced in August 1986 and produced until August 1989, this particular model combined the practicality and elegance of a luxury station wagon with the advanced traction capabilities of Mercedes-Benz’s innovative 4MATIC all-wheel-drive system. Positioned in the premium mid-size luxury segment, the S124 300 TE 4MATIC was a testament to German engineering during an era when Mercedes-Benz was synonymous with uncompromising quality, durability, and technological innovation. It carved out a niche for discerning European and international buyers who demanded both utilitarian functionality and refined driving dynamics, even in challenging weather conditions.

Powertrain and Engine Architecture of the Mercedes-Benz S124 300 TE (188 Hp) 4MATIC Automatic

At the heart of the Mercedes-Benz S124 300 TE (188 Hp) 4MATIC Automatic was the robust M 103 E 30 / 103.985 engine, a 3.0-liter (2962 cm3 or 180.75 cu. in.) naturally aspirated inline-six gasoline engine. This powerplant was celebrated for its smooth operation, reliability, and ample power delivery, characteristics that defined Mercedes-Benz engines of the period. Featuring a Single Overhead Camshaft (SOHC) valvetrain with two valves per cylinder and a multi-port manifold injection system, the engine produced a respectable 188 horsepower at 5700 rpm. Torque output was equally impressive for its time, peaking at 191.77 lb.-ft. (260 Nm) at 4400 rpm, providing strong acceleration and effortless cruising capability.

The power was channeled through a sophisticated 4-speed automatic transmission, known for its smooth shifts and durability. This transmission, typically the 4G-TRONIC unit, was designed to provide a comfortable and refined driving experience, prioritizing smooth transitions over aggressive downshifts. What truly set this model apart was its advanced 4MATIC all-wheel-drive system. Unlike permanent AWD systems, Mercedes-Benz’s 4MATIC of this era was an electro-mechanically controlled system that primarily drove the rear wheels, engaging the front wheels only when slippage was detected. This intelligent system provided enhanced traction and stability in adverse conditions without compromising fuel efficiency or handling dynamics on dry pavement. Performance figures included a 0 to 60 mph acceleration time of a swift 9.1 seconds and a top speed of 128.62 mph (207 km/h), making it one of the faster and more capable wagons of its day.

Fuel economy for the S124 300 TE 4MATIC was rated at approximately 16.4 US mpg in urban driving and 24.8 US mpg on the highway, respectable figures for a large, powerful, all-wheel-drive luxury vehicle from the late 1980s. The engine’s compression ratio stood at 9.2:1, and it had an engine oil capacity of 6.5 liters (6.87 US quarts) and a coolant capacity of 9 liters (9.51 US quarts), reflecting its robust design intended for long-term reliability.

Chassis and Suspension

The S124’s chassis was renowned for its exceptional ride comfort and stable handling. The front suspension utilized an independent wishbone setup, while the rear featured a sophisticated independent multi-link suspension. This innovative rear suspension design, a hallmark of the W124 generation, provided superior wheel control and improved ride quality compared to many contemporary systems. Braking was handled by ventilated discs at the front and solid discs at the rear, augmented by an Anti-lock Braking System (ABS), a significant safety feature for the time. Steering was a hydraulic cone worm with recirculation balls system, offering precise feedback and ease of maneuverability.

Design and Features

The Mercedes-Benz S124 300 TE 4MATIC epitomized the understated elegance and functional design characteristic of Mercedes-Benz in the late 20th century. Its station wagon (estate) body type, featuring five doors and seating for five, offered immense practicality without sacrificing aesthetic appeal. The design, penned by Bruno Sacco, was timeless, characterized by clean lines, robust construction, and excellent aerodynamic efficiency for its era. The vehicle’s dimensions — 187.6 inches in length, 68.5 inches in width, and 58.98 inches in height, with a generous 110.24-inch wheelbase — contributed to a spacious and comfortable cabin, further enhancing its appeal as a family or executive transporter.

Inside, the S124 offered a cabin built with high-quality materials and meticulous attention to detail. Ergonomics were excellent, with intuitive controls and supportive seating designed for long-distance comfort. Standard features typically included power windows, central locking, and the aforementioned ABS. The availability of 4MATIC was a premium option that significantly enhanced its utility in regions with inclement weather, providing a level of confidence and safety that few competitors could match. Options included leather upholstery, sunroof, and upgraded audio systems.

Driving Characteristics of the 300 TE 4MATIC Automatic

The 300 TE 4MATIC Automatic offered a distinctly different driving experience compared to its rear-wheel-drive counterparts and those equipped with manual transmissions. The automatic transmission, while smooth, resulted in a slightly less engaging driving experience. Acceleration was respectable, but not as brisk as the manual versions. The 4MATIC system, however, significantly enhanced stability and traction, particularly on slippery surfaces. The car felt planted and secure, inspiring confidence in all weather conditions. The gear ratios were tuned for comfortable cruising, with a focus on relaxed highway driving rather than sporty performance. Compared to the higher-output 300E-24 models, the 300 TE 4MATIC prioritized usability and all-weather capability over outright speed.

Equipment & Trim Levels

The S124 300 TE 4MATIC Automatic was generally well-equipped as standard. Key features included power windows, power steering, central locking, and the ABS anti-lock braking system. Interior upholstery was typically a durable cloth, although leather was available as an option. The dashboard layout was functional and ergonomically designed, with clear instrumentation and easy-to-reach controls. Optional extras included a sunroof, upgraded audio systems, automatic climate control, and heated seats. The 4MATIC system itself was considered a premium option, adding to the vehicle’s overall cost.

Market Reception & Comparison

The S124 300 TE 4MATIC Automatic was generally well-received by automotive critics. It was praised for its build quality, comfortable ride, and the added security of the 4MATIC all-wheel-drive system. However, some critics noted that the automatic transmission and the 4MATIC system added weight, slightly impacting performance and fuel economy compared to the lighter, rear-wheel-drive models. Compared to the 300E sedan, the 300 TE 4MATIC offered greater practicality and all-weather capability, but at a higher price point. Against competitors like the Volvo 240 wagon and the Audi 80 Avant Quattro, the Mercedes-Benz offered a more luxurious and refined experience, albeit at a premium.
