The Mercedes-Benz S124 300 TE (180 Hp) 4MATIC Automatic, produced between August 1986 and August 1989, represents a sophisticated and capable variant of the W124 series station wagon. The W124, manufactured from 1984 to 1995, is celebrated for its robust engineering, longevity, and classic design. The 300 TE 4MATIC combined a powerful inline-six engine with Mercedes-Benz’s 4MATIC all-wheel-drive system and a four-speed automatic transmission, offering a blend of luxury, performance, and all-weather capability. This model occupied a premium position within the W124 lineup, positioned above the base 230 TE and 260 TE models, and below the higher-performance 320 TE. It catered to buyers seeking a practical yet luxurious vehicle capable of handling diverse driving conditions.
Powertrain & Engine Architecture
The heart of the S124 300 TE 4MATIC Automatic is the M 103 E 30 engine, specifically identified by model code 103.985. This 3.0-liter (2962 cc / 180.75 cubic inches) inline-six engine was a hallmark of Mercedes-Benz engineering during the era. It features a Single Overhead Camshaft (SOHC) valvetrain operating two valves per cylinder, contributing to its smooth operation and inherent reliability. The engine is naturally aspirated, relying on atmospheric pressure for intake, and utilizes a Bosch K-Jetronic fuel injection system. This mechanical fuel injection system, while complex, was known for its precision and durability, delivering fuel through a network of lines and distributors. The compression ratio is 9.2:1, resulting in an output of 180 horsepower (132 kW) at 5700 rpm and 188 lb-ft (255 Nm) of torque at 4400 rpm.
The 4-speed automatic transmission, designated 722.3, was a crucial component of this variant. This transmission was known for its smooth shifting characteristics and robust construction. It featured a torque converter for smooth engagement and acceleration, and offered a selectable economy mode for improved fuel efficiency. The 4MATIC all-wheel-drive system employed a viscous coupling to distribute power between the front and rear axles, providing enhanced traction in slippery conditions. The system operates automatically, requiring no driver intervention, and contributes to the vehicle’s stability and handling.
Driving Characteristics
The 300 TE 4MATIC Automatic offered a refined and comfortable driving experience. The inline-six engine delivered smooth, linear power throughout the rev range, making it well-suited for both highway cruising and spirited driving. While not a sports car, the 300 TE 4MATIC could accelerate from 0 to 60 mph in approximately 9.3 seconds and achieve a top speed of around 127 mph (204 km/h). The automatic transmission provided seamless gear changes, enhancing the overall driving comfort. The 4MATIC system significantly improved traction, particularly on wet or snowy roads, providing a sense of security and control. Compared to the rear-wheel-drive 300 TE, the 4MATIC version exhibited reduced understeer and improved stability during cornering.
Compared to the 260 TE, the 300 TE 4MATIC offered a noticeable performance advantage due to its larger engine and increased torque. The 320 TE, with its larger 3.2-liter engine, provided even greater performance, but at a higher price point. The 300 TE 4MATIC struck a balance between performance, luxury, and practicality, making it an appealing option for buyers who desired a capable and comfortable all-weather vehicle.
Equipment & Trim Levels
The S124 300 TE 4MATIC Automatic was well-equipped for its time, reflecting Mercedes-Benz’s commitment to luxury and comfort. Standard features typically included power windows, central locking, power steering, and an adjustable steering column. The interior was typically upholstered in high-quality cloth or optional leather. The dashboard featured a classic Mercedes-Benz design with wood trim and analog gauges. Air conditioning was a common option, as were power-adjustable front seats and a sunroof. A premium sound system with an antenna was also frequently specified.
Optional extras included automatic climate control, heated seats, and a rear window wiper. The 300 TE 4MATIC also offered a range of exterior options, including different wheel designs and paint colors. The station wagon body style itself provided a significant level of practicality, with a large cargo area accessible through a rear tailgate. The rear seats could be folded down to further expand the cargo capacity.
Chassis & Braking
The S124 300 TE 4MATIC Automatic utilized a robust chassis designed for comfort and durability. The suspension consisted of independent suspension at all four wheels, featuring MacPherson struts at the front and multi-link suspension at the rear. This setup provided a smooth and controlled ride, even on uneven surfaces. The steering was a recirculating ball system, offering precise and predictable handling. The braking system featured disc brakes at the front and drum brakes at the rear. Anti-lock Braking System (ABS) was available as an option, enhancing braking performance and stability, particularly in emergency situations. Stabilizer bars were fitted to both the front and rear axles to reduce body roll during cornering.
The 4MATIC system added weight to the vehicle, necessitating a slightly stiffer suspension setup compared to the rear-wheel-drive models. This ensured that the vehicle maintained its composure and handling characteristics despite the added weight and all-wheel-drive configuration.
Market Reception & Comparison
The S124 300 TE 4MATIC Automatic was generally well-received by automotive critics. It was praised for its refined engine, comfortable ride, and all-weather capability. The 4MATIC system was particularly lauded for its ability to enhance traction and stability in challenging conditions. However, some critics noted that the 4MATIC system added weight and slightly reduced fuel economy compared to the rear-wheel-drive models. Fuel economy averaged around 18-22 mpg (US) in mixed driving conditions.
Compared to its siblings, the 300 TE 4MATIC offered a compelling combination of performance and practicality. The 260 TE was more affordable but lacked the power and refinement of the 300 TE. The 320 TE offered greater performance but came at a higher price. The 300 TE 4MATIC represented a sweet spot in the lineup, providing a luxurious and capable vehicle at a reasonable price point.
