Porsche is fast indeed, but let's do repeated runs of Model S/X vs Jaguar then see the numbers. Say for one hour straight. Then we can do a fair comparison. Keep in mind Model S/X really can't keep running on tracks at full power for long, but the I Pace has not "thermal" fade from being pushed beyond limits for continued operation in the 0 to 60 time. It is sustainable performance.
Even the Porsche has a temporary "boost" mode they admit is used for faster numbers. But even without that I believe it can do 0 to 60 in mid to low 3 seconds.
