KE-Jetronic for 190E Owners: How It Works, How It Fails, How to Fix It

Project Benz documents Mercedes 190E (W201) culture without softening it: Cosworth 2.3-16 and 2.5-16 homologation specials, the 235 hp Evolution II, AMG-tuned rarities, bagged dailies, JDM imports, and the indestructible 190D diesels. It is part owners' registry, part technical archive, with factory specs for every W201 variant, restoration and buyer's guides, paint codes, and wheel fitment, mapped to real cars in real garages worldwide. The cleanest Mercedes W201 builds and the reference to make sense of them, on one feed.
Mercedes-Benz built the 190E (W201) from 1982 to 1993 at its Sindelfingen and Bremen plants, producing 1,879,000 cars over eleven years. Bruno Sacco's team styled the 4.42-metre saloon, the smallest Mercedes in decades, and the press named it the “Baby Benz.” The halo model, the 2.5-16 Evolution II, made 235 hp at 7,200 rpm from a 2.5-litre four. Mercedes built 502 of them to homologate the DTM car that won the 1992 title with Klaus Ludwig.
Figures from Mercedes-Benz production records and DTM championship results (1982–1993). Variant counts follow factory homologation figures.

From the 1982 Stuttgart launch to the final 1993 example off the Bremen line, every milestone.
Mercedes-Benz launches the W201, the smallest Benz in decades. Bruno Sacco's team draws a 4.42-metre saloon that looks like a scaled-down S-Class. The press calls it the "Baby Benz."
Three Cosworth-developed 16-valve 190Es run flat-out for 50,000 km at Italy's Nardò ring, breaking long-distance world records. The road car launches at Frankfurt.
The 2.3-16 is replaced by the 2.5-16. New cams, bigger displacement, and a sharper focus on DTM homologation.
Aero-tweaked bodywork, wider tracks, and a short-stroke engine spec'd for DTM. Just 502 units, exactly enough to meet homologation rules.
235 hp, Aerodyne bodywork, towering rear wing, AMG suspension. 502 built. The W201 at its most extreme.
Klaus Ludwig drives the 190E 2.5-16 Evolution II to the DTM championship. The W201 stops proving itself.
After 1.879 million examples, the W201 is replaced by the W202. The cult follows.
Four Cosworth 190Es, one homologation war. Mercedes handed Cosworth the M102 four-cylinder and asked for more. What came back launched a homologation arms race with BMW that ran through 1993.
Evolution II
AMG aero, towering rear wing, 235 hp from a 2.5-litre four. The W201 at its most extreme, and the basis for the DTM championship car.
The one that started it. A Cosworth twin-cam 16-valve head on the M102, 185 hp in Euro tune. Limited-slip diff, sport suspension, discreet body addenda.
More displacement, more torque, smoother delivery than the 2.3-16. The basis for everything that followed, the sweet spot for road use.
Short-stroke 2.5-litre, lighter materials, wider arches, deeper front splitter. 502 cars to take the fight to BMW in the DTM.
The one. Aerodyne bodywork developed in the wind tunnel, that unmistakable rear wing, AMG-tuned suspension. 502 future six-figure collectibles.

The chapters that made the chassis: the record run, the touring-car war, and the homologation special owners argue about.
Quick answers on production numbers, the rarest variants, values and what to check before buying.
Mercedes-Benz built 1,879,000 W201s between 1982 and 1993 at its Sindelfingen and Bremen plants, making the 190 and 190E one of the company's highest-volume model lines of the era.
The 2.5-16 Evolution II is the rarest mainstream 190E: Mercedes built just 502 in 1990 to homologate the DTM car. The 1989 Evolution I was also limited to 502 cars. Both now reach six-figure values.
The 2.3-16 (1984 to 1988) was the original Cosworth 16-valve car with 185 hp in European tune. The 2.5-16 (1988 to 1993) added displacement and torque and used a stronger cylinder head, which makes it the more usable road car of the two. See every W201 variant compared.
Yes. The W201 is over-engineered, mechanically robust and well supported by parts and an active owner community. Before buying, check for rust at the rear subframe mounts, the rear wheel arches and the floorpans. Our 190E buyer's guide lists what to inspect.
Values span a wide range. A tidy four-cylinder 190E remains an affordable classic, while a Cosworth 2.5-16 Evolution II reaches six figures. Condition, mileage and originality drive the price. Try the 190E value estimator for a model-specific figure.
W201 is Mercedes-Benz's internal chassis code for the first-generation compact executive saloon sold as the 190 and 190E and built from 1982 to 1993. The W202 C-Class replaced it.
