I could have saved $40,000 on my MS. And you can too. My P85D is in the shop, and the valet was kind enough to bring me the same color, similarly equipped S85 as the loaner. Yes, my P85D is faster, but unreasonably so. You can't really use it much. I don't punch it anymore because every time I do it's so annoying that all my stuff flies into the back seats. From driving the S85 I think it is fast enough, and in some cases I don't even feel a difference in a rolling acceleration. On the S85 without range mode turned on I'm getting 50w/mi better efficiency than my P85D gets with range mode turned on, and 100w/mi better efficiency when comparing non-range mode to non-range mode. Oh and the best part: the S85 is so much more quiet!!! The P85D has the constant motor whine from the front motor. Driving the S85 sounds like what you would expect from an EV. Do I regret my purchase of the P85D? Nope, my wife said go for it, so I'm happy to have had the opportunity to splurge on my mid-life crisis mobile. But next time I'll save $40,000. For those of you contemplating what to order, I suggest you spend more time test driving the S85, you may just decide to save the money and use that towards your wife's MX.
