There is a link in this thread to a brochure you can download:

that also says 560 NM.
The websites are often wrong.
I noticed when the F30 M Sport came out it showed the 0-62 of a 335i as 5.9 (same as the 328i). It is now shown correctly as 5.5.
I’ve also emailed them in the past about incorrect tyre sizes shown for the E90 330d M Sport.
