M47R
Rover Group (UK) and Steyr (Austria), both subsidiaries of BMW, collaborated on re-engineering the M47D20 to create a transverse configuration for use in the Rover 75 front wheel drive saloon, as well as their all wheel drive Land Rover Freelander. The same engine was later deployed by MG Rover in the Rover 75 Tourer and MG ZT. The general configuration of an M47R ("M47 Rail") differs to the original design by the introduction of common-rail technology, a transverse orientation, different turbochargers, and more sophisticated temperature management systems. However, the core 1951 cc heads of the M47R and M47D20 are the same. Combining a common-rail system with a relatively small engine capacity created engine temperature problems. More hardware was added to help control temperatures which also helped to escalate weight, fuel consumption, and manufacturing costs. The BMW Steyr plant manufactured and supplied M47R engines with the same power output as the M47D20 from 1999 to 2006.
