    I'm certain that launch from a standstill is where the D will really shine relative to other exotics and the P85+, but curious to get your thoughts on what passing power at highway speeds will be like. Since there's 50% more torque at all times relative to the +, I imagine there will be a very noticeable upgrade at speeds above 65. At least I hope so :)

    My understanding is that they're about the same. It's 0-50 where the real difference shows. Both have plenty of passing power at highway speeds. To steal a phrase, "It's not point and squirt, it's teleportation".

    From the available data, it is beginning to seem likely that the peak output is clear to the same. However, at higher speeds the current car loses power site to back EMF (I presume - all I know is I was shown a curve the gets down to about half the output over 100 mph.)

    It is likely that the D cars will suffer less power loss at high speeds due to the taller front motor gearing, thus giving a relative increase in power.

    Don't worry about it....

    I have a P85 and THAT has all the passing power anyone would ever need outside a NASCAR track...the P85D will be "insane" as Elon said when he rolled it out :love:

    The question was about highway passing. If you are not on the german autobahn, there's no need to talk about speeds over 100mph.

    I think the passing power of the P85D over P85+ will be most noticeable between 130 and 155 mph...

    That's not passing power, that's race track power. Passing is, depending on the speed limit, somewhere between 55-85mph

    Dude, he's messing with us and it was meant as a joke :biggrin:. A P85 top speed is 130-135mph vs P85D at 155mph. P85D will always pass faster above 130mph!

    There is only about 0.2 or 0.3 second difference in the P85 and S85 when it comes to 45 mph to 65 mph passing times. The only direct comparison I could find was at Motor Tend. No doubt the P85D will be even quicker. But with my S85 I find the highway passing is so fast that the main problem is not running down the cars in front of the one you are passing. Real world I can seldom use full power. Passing is almost always faster than a similar powered ICE because there is no lag, which makes it feel even quicker.

    My understanding is that P85D will have significantly better passing power at any speed. Especially higher speeds, due to the taller gearing.

    It is really all kind of moot. As I think about it more I am a little concerned that there may be more and more spectacular crashes as a result of such incredible power. Such power has until now been unavailable to such a broad market. When you buy a $500K supercar you tend to be a little careful with it.

    I hope not both for safety and for insurance rates.

    There are other cars that have similar power for only slightly higher prices (and lower prices if you are willing to consider used vehicles).

    That said, I agree, I am quite sure there are people who are buying P85D now only because it's the newest thing to show off to their friends, and have no idea of the potential risks when driving a car with this much power, especially at the low end with near-zero latency. Those same people probably wouldn't have bought a Porsche 997 Turbo or a Nissan Skyline GT-R as it was too impractical, and for the most part, only the 'right' demographic was buying those cars.

    I can assure you that the P85 and + version that I pilot have more than enough passing power. Many of my unsuspecting passengers have emitted "holy crap!" comments when I nail the go pedal on a freeway on ramp or passing slower traffic on the freeway. The P85+ acceleration at any speed is literally breathtaking. It's quicker than my still pretty awesome BMW M3 with a 4 liter V8 and 6-speed stick.

    Yes. The NISMO GT-R was one that I had considered as well. I think the issue with the TMS is that it's styling and price make it more generally accessible/appealing.

    Agree with you Steve and same happens to my passengers. Looks like we are not only neighbors but have the same garage contents. Just tracked the M3 a few weeks ago and it was so nice to come home to the MS :)

    this is NOT true. Don't care what motor trend said or what tests they did! I have an email from the higher ups at tesla that confirm all three versions of the cars 60mph+ will travel at the exact same speed. So....if that p85D is next to my "old" P85 and we're noth going 60mph on the freeway already the D won't pull away from me. We'll be dead even! The only true difference is on the 0-60 takeoff. Don't get me wrong. THe car is still insanely fast....

    I can assure you without question, this is NOT true.... I've tested the P85 vs S85 and the P85 pulls away at speed. I will have both a P85D and a P85 in my garage shortly with a video to show the differences.....

    On most big highways in europe, the outer lane moves at 80-90 mph. 100mph is completely normal passing speed. I travel a lot in Germany where 100 mph is a completely normal thursday afternoon drive, with 120+ mph passing speed.

    I have as well. Now while I agree if you start out one will pull away from another. However if you take a 60,85, and p85 and line them up all going 60 mph with cruise set and then all floor at the same time one will not pull away from another. Theyare all equal.

    Now ow I suppose if a person had a faster response time than another jump seats (which add weight structurally etc) but.... From what both my service center manager and Jerome guillen have confirmed all Teslas are created equal 60mph+.

    @breser who was kind enough to allow us to test our P85 against his S85 he can confirm this!
