Final drive and transmission ratios affect 0-60 too. I've found numbers for the X5 but not for the Cayenne 8 speed so the jury is out on that. But another factor in addition to torque (what acceleration is all about) is where the engine makes that torque. The Cayenne V6 reaches maximum @3000 rpm while the X5, being a twin turbo is making it's 300 lb ft as low as 1500 rpm on a plateau all the way to 5000 rpm. I think that's part of the difference here.
Porsche is usually conservative with their performance claims so you'd expect a couple of tenths of wiggle room. But 1.2 seconds is a huge difference and at least brings up questions, especially since other testers (except Riley
)have confirmed Porsche's times.
