I have two unrelated comments now that I’ve got my car back and the upgrade seems to work, at least during the 40 mile drive back home.
First, like some others on this forum, I complain about lots of things: nags on AP, poor communications from the company, etc. However I do want to express my appreciation. I suspect that I am not the only one on this forum to pitch people on the wonders of the MS, boring my friends with a long a evangelical speech when the opportunity arises. Lately, the ludicrous upgrade has been one of the chapters in my speech.
Consider buying a 911 Turbo just before Porsche introduces a Turbo S model for the next year. I would not feel happy. Of course Porsche would be happy to take a depreciated Turbo in trade and sell me a Turbo S. But imagine Porsche saying ‘We feel badly we told you yours was the king of the hill just before we came out with a better car, so if you like, we will take yours back and upgrade it from a Turbo to a Turbo S (or at least 95% of a Turbo S) for half of the new price differential.’
I would probably have a heart attack if that statement came from Porsche, but here I am with a newly minted P85DL in my garage. And the comparison is actually very apt, since the Porsche website claims the Turbo does 0 to 60 in 3.2 seconds, and the Turbo S in 2.9. A remarkable coincidence, don't you think? Of course the upcharge for a turbo S is ~$30k, which in fairness includes some Turbo options as standard. But as you all know, upgrading to a P85DL cost me $5k.
Thank you Tesla.
The second completely unrelated comment regards the P85+ loaner I’ve been driving the past few days. It’s a fine car as all Tesla products are, but I was surprised by the comparison with the P85D (pre Ludicrous). We all know dual motors yield low-speed acceleration but I was surprised at how similar the P85+ and P85D acceleration felt at highway speeds. I guess I shouldn’t be surprised given the P85D’s battery limitation.
But leaving aside low-speed acceleration, I was also surprised at the advantage all wheel drive gives the P85D. I discovered the P85+ rear end slides and axle-hops in situations the P85D never would. (I guess I drive these cars harder than I thought.) Admittedly, some of it might have been the P85+’s inappropriate Pilot Sport summer tires in weather just above freezing (I have Sottozero snow tires on the P85D) but the pull from the P85D’s front axle really adds stability and reduces the traction required in the rear.
The odd thing was that there is something about the suspension tune on my P85D that I liked much more than the P85+. The ride is less harsh, yet there seems to be as much handling precision and (very surprisingly) noticeably more roll stiffness than the +. The P85D somehow feels more stable and planted, even cruising in a straight line. The P85+ tramlined a bit, although that might have been the summer tires; however my P85D does not tramline on its summer tires. The difference in suspension feel might just have been coils on the loaner vs. an air suspension on my car: I’m not sure. Both cars had 21” wheels and the loaner’s alignment was good: it tracked perfectly straight. I know the P85D suspension has varied: I took delivery of my car at the beginning of 3/15. So the bottom line surprise for me was that the older car’s higher-speed acceleration was almost as good, but the P85D beats it on subjective handling feel. Go figure. Of course my car’s acceleration now materially beats the loaner’s at all speeds.
