What engine was in a rover 825?

The KV6 version of this engine was first used in the Rover 825, but it should be noted that this was a very different beast to the similarly-named power unit that would find its way into the Rover 75 and MG ZT. An insider described the earlier engine as very much a practice run, produced in an almost hand-built way - unfortunately, that led to fragility in the 825, and many power units expired before they hit the 60,000 mile mark.
