This information was gathered from offical Porsche Publications, mostly sales brochures. Asterisk (*) indicate data obtained from other sources or extrapolated from the material I already had. There's also a statement at the bottom of each spec sheet stating that the data may change without notice. For more specification try Phil Tong's 928S4VR Site or 928 Specialists.

I don't have Spec Sheets for the European Versions, but I'm working on it. Starting in 1989 all 928s had the same specifications.
