Background
From January 1974 to January 1982, Mercedes spent in excess of £600 million researching and developing the 190 range (internally designated W201), which was manufactured in various guises from 1982 to 1993. Mercedes later said that the 190E was “massively over-engineered”. That’s Mercedes saying that. A company where the teaspoons in the staff canteen were probably built to withstand earthquakes.
The ‘E’ after 190 stands for Einspritzung, or fuel injection for non-Teutonic readers. This Bosch KE-Jetronic system delivered more power and fuel efficiency than its carburettor-equipped predecessor.
Desperate to put the 190E into motorsport, Mercedes turned to Cosworth to develop an engine for rallying. But once they’d seen what the turbocharged, four-wheel drive Audi Quattro was doing, they switched focus to DTM - the German Touring Car Championship. This meant that for homologation, Mercedes had to produce a 190E Cosworth for the road.
The detuned 2.3-litre 16-valve Cosworth engine developed 185bhp and 174lb.ft of torque and would take the car to 62mph in under 8 seconds, going on to a top speed of 143mph. In 1988, a larger 2.5-litre 16-valve engine brought power levels up to 204bhp.
Of course, the Cosworth cars didn’t just have a different engine to the standard 190E, they also had a laundry list of upgrades including aerodynamic body kits, quicker steering, dog-leg manual 5-speed gearbox, limited slip diff as standard, lower and stiffer suspension and a sportier interior.
1989 and 1990 brought two more powerful 190Es - the Evolution and Evolution II respectively - but these were only built-in limited quantities of around 500 each for DTM homologation and so are much rarer, and hugely pricier, than the “standard” 16V Cosworth’s like the one you see for sale here.
