Mercedes-Benz W123 230 (109 Hp)

The Mercedes-Benz W123 represents a pivotal era for the German automaker, solidifying its reputation for building durable, comfortable, and safe mid-size automobiles. Produced between July 1975 and August 1980, the 230 model, powered by a 2.3-liter inline-four engine producing 109 horsepower, was a key variant within the W123 range. This generation succeeded the W114/W115 and was itself superseded by the W201, establishing a lineage of successful Mercedes-Benz sedans. The W123 was not initially a major seller in the United States, as it was considered too small and less luxurious than the larger S-Class models. However, it gained a following among those seeking a more practical and fuel-efficient luxury car.

The Mercedes-Benz W123 230: A Detailed Overview

The W123 series was a significant departure from its predecessors, introducing improved safety features, a more refined interior, and a wider range of engine options. The 230 model, while not the most powerful in the lineup, offered a balance of performance and economy that appealed to a broad customer base, particularly in Europe where fuel costs were a greater concern. It was designed to be a comfortable and reliable family car, capable of handling long distances with ease. The W123’s robust construction and engineering contributed to its longevity, with many examples still on the road today.

Engine & Performance

The heart of the W123 230 is its 2.3-liter (2307 cm³) inline-four cylinder engine, designated M 115 V 23 / 115.954.

The engine features a single overhead camshaft (SOHC) valvetrain with two valves per cylinder and utilizes a carburetor fuel injection system. While not a performance powerhouse, the engine provides adequate power for comfortable cruising and everyday driving. The power-to-weight ratio is 12.4 kg/Hp, or 80.7 Hp/tonne, indicating a respectable, though not sporty, driving experience. Acceleration from 0 to 100 km/h (0-62 mph) takes 13.7 seconds, and 0 to 60 mph is achieved in approximately 13 seconds. The top speed is rated at 170 km/h (105.63 mph).
