Couple of interesting items on Porsche's 991 web site.
Discussion
If you go to the 991 section of Porsche's official site, choose the 991S and go to the 'In Detail' section there are a couple of items I found interesting.
First is in the engine diagram section. At item 16, it clearly shows a power steering pump (stated to be 'in conjunction with PDCC'). Why would a power steering pump be needed for electronic power steering? Is there some kind of 'hydraulic option'?
Second, at the bottom of the page is a very discreet and lonely-looking link to www.michelin.com. No comments or reasons for the link. Odd. All of the launch cars that I've seen photographed seemed to be on Pirelli P-Zeros and Porsche doesn't even approve the Michelin tyres (PSS) for any of their cars yet. So why the link to Michelin? www.pirelli.com would have made more sense. What do we read into the Michelin link?
