While the 190 E 2.5-16 Evolution was winning its first victories, the designers set to work on its second development stage in August 1989. 500 cars had to be manufactured in order to obtain the homologation. In May 1990, the last of the 502 manufactured cars finally left the conveyor belts in the Bremen factory. After that, the production of the car was taken over by AMG. The 190 E 2.5-16 Evolution II made its racing deput on the Nürburgring North Loop on 16 June 1990. From the date of the DTM final run on the Hockenheimring on 15 October 1990, all factory-supported teams used the Evo-II technology.
