30 September 2025 (updated) Mercedes-Benz 190 engines
Between 1982 and 1993, the Mercedes-Benz 190 established itself as the entry-level model of the Stuttgart brand and offered a remarkable variety of engine options. The Mercedes-Benz 190 engines ranged from economical diesel units to high-revving sports engines and shaped an entire generation of compact saloons. This range of engines reflected the technological development of the 1980s and laid the foundations for modern Mercedes technologies.
Mercedes-Benz 190 Generation I (1982-1993)
The only generation of the Mercedes-Benz 190 was a pioneering period for the brand in the compact segment and was characterized by exceptionally robust and durable engines. The mileage was impressive: while the tried-and-tested diesel engines easily reached 400,000 to 600,000 kilometers with proper maintenance, the petrol engines also regularly managed 300,000 to 400,000 kilometers without major repairs. Major engine damage was extremely rare in all Mercedes-Benz 190 engines and was usually due to extreme neglect. The absolute top engine of this era was the 2.5-16V with 204 hp - a technical masterpiece that catapulted Mercedes-Benz into the motorsport elite and is still considered one of the best four-cylinder engines of all time.
Mercedes-Benz 190 petrol engines: Generation I (1982-1993)
The Mercedes-Benz 190 petrol engine range initially comprised the tried-and-tested M102 engine in various displacement variants. The 190 (W201) started in 1982 with the 1.8-litre engine (90 hp), followed by the 2.0-litre (105-122 hp) from 1983. These Mercedes-Benz 190 engines were characterized by their robustness and durability, but had relatively high fuel consumption. The technological highlight was the 2.3-16V (M102.983) with 185 hp, which was introduced in 1984 and had four valves per cylinder as well as Cosworth-developed cylinder head technology. Even more spectacular was the 2.5-16V (M102.991) from 1988 with 204 hp, which served as the homologation model for the DTM. These Mercedes-Benz 190 engines were considered virtually indestructible and became sought-after collector's items.
Mercedes-Benz 190 diesel engines: Generation I (1982-1993)
The Mercedes-Benz 190 diesels were dominated by the legendary OM601 engine, which was offered in different variants. The 190 D 2.0 (72 hp) was available from 1983, later joined by the more powerful 190 D 2.5 (90 hp). The absolute highlight was the 190 D 2.5 Turbo with 126 hp, which was introduced in 1988 and was regarded as one of the first turbodiesels in the compact class. These Mercedes-Benz 190 engines developed into the most reliable drive units of the entire model series - the OM601 without turbocharger regularly achieved mileages of over 500,000 kilometers and was considered practically indestructible. Even the more complex turbodiesel proved to be extraordinarily durable, with only the turbocharger unit occasionally requiring an overhaul after around 200,000 kilometers.

| 2.5-16V M102.991 | 204 HP | 11.0-12.0 l/100km | Very high-maintenance | Very good |
| 190 D 2.0 OM601 | 72 HP | 6.5-7.2 l/100km | Practically indestructible | Very good |
| 190 D 2.5 OM602 | 90 HP | 6.8-7.5 l/100km | Extremely robust | Very good |
| 190 D 2.5 Turbo OM602 | 126 HP | 7.2-8.0 l/100km | Turbocharger after 200,000 km | Very good |
