Mercedes-Benz S124 (facelift 1989) 300 TE-24 (220 Hp) Automatic
The Mercedes-Benz S124 (facelift 1989) 300 TE-24 (220 Hp) Automatic represents a pinnacle of German engineering and luxury from the late 1980s and early 1990s. As part of the iconic W124 generation, a series revered for its exceptional build quality, durability, and refined driving dynamics, the S124 designation specifically refers to the station wagon (or “estate” in European parlance) variant. The 300 TE-24, introduced with the 1989 facelift, distinguished itself with a potent 24-valve inline-six engine, offering a blend of performance, practicality, and sophisticated luxury that was highly sought after in its primary European market. While the W124 platform in various forms saw widespread global distribution, including significant sales in the United States, this particular 300 TE-24 model, with its advanced M104 engine, underscored Mercedes-Benz’s commitment to combining utility with spirited performance and cutting-edge technology for its era.
Engine and Performance of the Mercedes-Benz S124 300 TE-24
At the heart of the Mercedes-Benz S124 (facelift 1989) 300 TE-24 (220 Hp) Automatic lies the formidable M 104 E 30, also known by its engine code 104.980. This naturally aspirated, front-longitudinally mounted inline-six engine was a significant step forward for Mercedes-Benz, notably featuring a Dual Overhead Camshaft (DOHC) valvetrain with four valves per cylinder, totaling 24 valves. This advanced configuration, uncommon for a station wagon of its time, allowed for superior breathing and efficiency, contributing to its impressive power output. The engine displacement measures 2960 cubic centimeters (180.63 cu. in.), producing a robust 220 horsepower at 6400 rpm and 195.45 lb.-ft. of torque at 4600 rpm. This power-per-liter figure of 74.3 Hp/l was quite respectable for a naturally aspirated engine of the period.
Power is channeled to the rear wheels via a smooth and durable 4-speed automatic transmission, a common and reliable choice for Mercedes-Benz models of this vintage. This powertrain combination allows the 300 TE-24 to achieve a spirited acceleration from 0 to 60 mph in a mere 7.8 seconds, with a maximum speed of 134.84 mph. These performance figures were outstanding for a luxury station wagon, enabling comfortable high-speed cruising on European autobahns and confident overtaking. The vehicle’s weight-to-power ratio stands at 7.2 kg/Hp (or 138.4 Hp/tonne), highlighting its athletic capabilities. Fuel efficiency, while not its primary focus, was reasonable for a vehicle of its size and performance, with urban consumption rated at approximately 16 US mpg and extra-urban driving yielding around 24 US mpg on gasoline. The engine features multi-port manifold injection and a compression ratio of 10:1, ensuring efficient fuel delivery and combustion.
Design and Features of the S124 Station Wagon
The Mercedes-Benz S124 (facelift 1989) 300 TE-24 (220 Hp) Automatic embodies the timeless and functional design philosophy of the W124 generation. Its body type is a 5-door station wagon, designed to offer both luxurious passenger comfort for five occupants and substantial cargo versatility. The 1989 facelift brought subtle yet impactful enhancements to the W124 line, including revised side cladding (often referred to as “Sacco panels”), integrated door handles, and a slightly restyled grille, contributing to a more modern and cohesive aesthetic. Despite these updates, the core design remained true to the W124’s reputation for understated elegance and aerodynamic efficiency.
Dimensions of the S124 are substantial, with a length of 187.6 inches, a width of 68.5 inches, and a height of 58.62 inches. A generous wheelbase of 110.24 inches contributed significantly to the car’s stable ride and spacious interior. The engineering emphasis on ride quality and safety is evident in its chassis setup. The front suspension utilizes a wishbone design, while the rear features an advanced independent multi-link suspension system, providing a sophisticated balance of comfort, handling, and load-carrying capability. Braking performance is robust, with ventilated discs at the front and disc brakes at the rear, complemented by an Anti-lock Braking System (ABS) as a standard assisting feature, a crucial safety innovation for its time. Steering is handled by a hydraulic power steering system with a cone worm and recirculation balls mechanism, offering precise and responsive feedback. The vehicle rides on 195/65 R15 tires mounted on 6.5J x 15-inch wheel rims, providing a comfortable and grippy contact patch.
