It is debated whether the 2.5 L engine was developed and built by Mercedes or Cosworth.
Mercedes was not keen to broadcast the fact that their most sporting saloon car has an engine developed by a British company. However some cylinder heads from 2.5 L cars are stamped with the Coscast logo indicating they were cast at Cosworth's foundry just like the 2.3s. Cosworth also list the project code "WAB" for the development of the 2.5-16 valve head just as they do for the 2.3-16 valve head.
Za EVO I...
The Evo I's output similar to the 202 bhp (151 kW) of the "regular" 2.5-16. However this car had a redesigned engine of similar capacity but, most importantly, a shorter stroke and bigger bore which would allow for a higher rev limit and improved top-end power capabilities. Additional changes stretch to "rotating masses lightened, lubrication improved and cam timing altered". Cosworth also list a project code "WAC" for the development of the short-stroke Evolution engine.
ZA EVO II...
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.
