1985-1989 Mercedes-Benz S124 300 TE (188 Hp)

The Mercedes-Benz S124 300 TE (188 Hp) represents a significant iteration within the lauded W124 series, produced from 1984 to 1995. Specifically manufactured as a station wagon – known as an “estate” in European markets – from May 1985 to August 1989, this variant offered a compelling blend of luxury, performance, and practicality. While not as prevalent in the United States as its sedan sibling, the 300 TE established itself as a premium family vehicle, celebrated for its robust engineering, elegant design, and reputation for exceptional reliability. It occupied a mid-range position within the W124 lineup, offering a step up in performance and refinement from the base 230 TE, but remaining more accessible than the flagship 320 TE.

Powertrain & Engine Architecture

The heart of the S124 300 TE (188 Hp) is the M 103 E 30 / 103.983 engine, a 3.0-liter (2962 cc or 180.75 cubic inches) naturally aspirated inline-six gasoline engine. This engine was renowned for its smooth operation, durability, and responsive power delivery. It featured a Single Overhead Camshaft (SOHC) valvetrain with two valves per cylinder, and a Bosch K-Jetronic fuel injection system, a mechanical system known for its reliability and precise fuel metering. The engine produced 188 horsepower at 5700 rpm, yielding a power-per-liter output of 63.5 hp/liter. Torque output was equally impressive, reaching 260 Nm (191.77 lb-ft) at 4400 rpm, providing strong pulling power throughout the rev range.

The powertrain layout is a classic Mercedes-Benz configuration: a front-mounted, longitudinal engine driving the rear wheels. This arrangement contributes to balanced weight distribution and predictable handling. The 300 TE was primarily equipped with a 4-speed automatic transmission (722.3 series), although a 5-speed manual transmission was available as an option, particularly in European markets. The automatic transmission was designed for smooth and refined gear changes, prioritizing comfort over outright performance. It featured a torque converter for smooth launches and a hydraulic control system for precise shifting.

Driving Characteristics

The S124 300 TE with the automatic transmission delivered a comfortable and refined driving experience. While not as overtly sporty as the manual transmission versions, the automatic provided effortless cruising and smooth acceleration. The 4-speed automatic’s gear ratios were optimized for fuel efficiency and relaxed highway driving. Acceleration from 0 to 60 mph was achieved in approximately 9.5-10.5 seconds, depending on load and driving conditions, slightly slower than the manual variant. The engine’s torque characteristics allowed for confident overtaking maneuvers, and the rear-wheel-drive configuration provided balanced handling. Compared to the 230 TE, the 300 TE offered noticeably more power and responsiveness, making it a more capable all-around vehicle. However, the higher-output 320 TE provided a more substantial performance upgrade.

Equipment & Trim Levels

The S124 300 TE came standard with a comprehensive array of features reflecting its premium positioning. Interior appointments included high-quality cloth or leather upholstery, wood trim, and a well-designed dashboard layout. Standard equipment typically included power windows, central locking, power steering, and an anti-lock braking system (ABS). Optional extras included a sunroof, automatic climate control, heated seats, and a premium sound system. The station wagon body style itself was a key feature, offering a large cargo area accessible through a rear tailgate. The rear seats could be folded down to further expand cargo capacity. Trim levels varied slightly depending on the market, but generally focused on enhancing comfort and convenience.

Chassis & Braking

The S124 300 TE utilized a robust chassis designed for both comfort and handling. The front suspension featured independent wishbones with coil springs and shock absorbers, while the rear suspension employed a multi-link independent setup, a sophisticated design for the time. This rear suspension significantly improved ride quality and handling stability, particularly when carrying a load. Braking was provided by ventilated disc brakes at the front and solid disc brakes at the rear. The braking system was assisted by ABS, enhancing safety and control during emergency stops. Steering was handled by a power-assisted recirculating ball system, offering precise control and ease of maneuverability. Stabilizer bars were fitted to both the front and rear axles to reduce body roll during cornering.

Market Reception & Comparison

The S124 300 TE was generally well-received by automotive critics. It was praised for its build quality, comfortable ride, and spacious interior. The inline-six engine was lauded for its smoothness and reliability. However, some critics noted that the automatic transmission could feel slightly sluggish compared to the manual option. Fuel economy was considered respectable for a vehicle of its size and engine displacement, averaging around 17-20 mpg in mixed driving conditions. Compared to the 230 TE, the 300 TE offered a significant performance advantage, justifying its higher price point. The 320 TE, with its larger engine, provided even greater performance but came at a substantial premium. The 300 TE struck a balance between performance, luxury, and value, making it a popular choice among discerning buyers.
