Only 502 units of the Evolution model were produced for homologation in compliance with DTM rules. For those customers desiring even more performance, a PowerPack option engineered by AMG was available for DM 18,000. The PowerPack option included hotter camshafts, a larger diameter throttle body, more aggressive ignition and fuel management as well as optimization of the intake and exhaust systems. The net result was an additional 30 bhp (22 kW).

In March 1990, at the Geneva Auto Show, the 190 E 2.5-16 Evolution II was shown. With the success of the first Evolution model, this model's 502-unit production was already sold before it was unveiled. This car retailed in 1990 for USD $80,000.

The "Evo II" included the AMG PowerPack fitted to the same short-stroke 2.5 engine as the Evolution, as well as a full SLS suspension allowing vehicle ride height to be adjusted from an interior switch. An obvious modification to the Evolution II is a radical body kit (designed by Prof. Richard Eppler from the University of Stuttgart) with a large adjustable rear wing, rear window spoiler, and Evolution II 17-inch wheels. The kit served an aerodynamic purpose—it was wind tunnel tested to reduce drag to 0.29, while at the same time increasing downforce. Period anecdotes tell of BMW research and development chief, Wolfgang Reitzle, saying "the laws of aerodynamics must be different between Munich and Stuttgart; if that rear wing works, we'll have to redesign our wind tunnel." The anecdote claims that BMW did.[16]

As mentioned 500 were made in "blauschwarz" blue/black metallic. But the last two, numbers 501 and 502 were made in astral silver.
