I don't think so, my wife's Cayenne is fitted with isofix in the front seat.No vehicle (except two-seat vehicles) is ever equipped with child seat attachment points on the front passenger seat. AFIK that is a government safety standard.

Glad to see someone post with direct evidence. Until I found the pdf file that I originally posted in this thread, i too thought Isofix would not be installed in a front passenger seat as did Michael. However, the file clearly shows that it is done and not just in 2 seaters. I assume the front passenger airbag is more sophisticated than in the old days. I'd expect the warnings still note greater safety if installed in the rear seats.I don't think so, my wife's Cayenne is fitted with isofix in the front seat.
