Hi Ossie, I did take note of the horsepower figure as quoted on the website, but the text makes no reference to the extra horses. A couple of things I noticed were a black box on the left hand side of the engine bay the purpose of which I am not aware of.
The other items of interest were the oil pressure reading at idle (engine not quite hot enough), and the rev counter red/orange lined at 5000 rpm. This seemed to be the 'rev limit' on the earlier models, whereas the later ones showed a reading of 5300 rpm.
This is a terrific website as it gives you pricing on many models, as well as some pretty good pictures overall which give you an insight into what's what and what it looks like. I am quite amazed at the 6.9 prices - wish they'd be the same in this country. Regards Styria
BTW, did you notice the Lorinser steering wheel ? IMO, somewhat nicer than an AMG unit.
