What does the 'M' in MDi stand for?

Post by kenwatson »

I have a Series III Land Rover with an MDi Turbo Diesel engine from a 1990 Montego.
While I have regarded these engines highly for some time and have read a good deal about them, I don't recall ever seeing any reference to the significance of 'MDi'. Naturally, I appreciate that the 'Di' bit is 'Direct Injection' but whatever does the 'M' stand for?
The evolution of the engine designations ('B' to 'O' to 'MDi' to 'L' to 'G') doesn't give anything away and I have almost come to the conclusion that it doesn't stand for anything at all. Hopefully, someone out there will be able to put me straight :?:

Now that is a very good question. The Prima / MDI / 500 series was indeed a diesel-ised version of the O series developed by Perkins.

I think it could possibly be M series Diesel MDi, (as the M series petrol was also in development at that time).
