    Had a chance to try out a Vmax run on a private road. 75% charge. No dice.

    anyone else verified a speed near 155?

    since the description says something like 'passing maneuvers up to 155mph' I suspect only under perfect conditions (95-100% charge, battery cool enough) would it only briefly hit 155mph for a few seconds but in general it wont be able to come near that and certainly won't be able to sustain that.

    With an early car doing a vigorous launch you can end up well over 120. If I creep up to 120 that's all she wrote. I like the 'passing maneuvers' description.

    What power draw is needed to sustain >130 mph? Let's say on a nice 70 F day with no winds.

    Reason I ask is because I've definitely held 80 mph with less than 40 kW draw. Seems like acceleration is more the determining factor as to when the limiter appears because that's what generates the heat.

    I appreciate the effort to max out the vehicle.

    I do question your assumption that the car will go 155, despite the manufacturer's suggestion that it could be possible under certain conditions. Passing? Really, Tesla? That is how you justify raising the limit to 155?.

    There is a difference between moving an electronic restriction up to 155 and a vehicle being able to arbitrarily achieve that velocity.

    Perhaps someone could test a P85D at high elevation (Rockies?), at a steep decent (10% grade), drafting behind, say, a Cayanne Turbo, and see how close to 155 they get.

    I don't recall the previous limited speed (135 perhaps?), but were people hitting the previous limit? If not, it's reasonable to assume they won't be hitting the higher limit either, at least under normal conditions.
