On the page with the technical articles, you can also read about the engines used, etc. However, there's a mistake with the AJM. It states that the MKB=AJM, GKB=EKL, which doesn't exist in that configuration. The EKL is listed with 6 (=6 gears?), but is designated as 01E.5. However, according to my , the EKL does not exist.
Okay, in my case, the MKB (which is AJM) is related to the GKB (which is DRW).
