You choose to believe Car & Driver over Autosport and McLaren - I do not.
I gather that it is so difficult to you to give-up the idea that you were so much wronged by Tesla, that you are loosing objectivity with every post on this subject. I never said that I believe one car magazine over another. What is clear now that the assumption that Tesla lied about matching performance of McLaren F1 is dead wrong based on facts that nobody cared to research before jumping to this conclusion. We have is real test data from three magazines that tested the car back in the nineties, the British Autocar tested F1 at 3.2s, presumably without rollout (equivalent to 2.9s with a rolout), but in tests by two american magazines, both with rollout, F1 was significantly slower.
In Aug 1994 Issue Car and Driver reported test time of 3.2s with rollout.
In November 2012 article Road and Track reported that according to their 1997 test McLaren F1 achieved 3.4s with rollout.
So in three documented tests F1 0 to 60mph acceleration time was 2.9s, 3.2s, 3.4 s (all with rollout or adjusted to be equivalent to a test with rollout). The bottom line is that Tesla claim that P85D, with 3.2s 0 to 60 time, based on data from two US car magazines, matches performance of McLaren F1, is completely legitimate, if not overly conservative.
In the 1994 article they say nothing about rollout and it is not clear how and where they tested it. But since you are writting e-mails ...
Well, you are grasping at straws here. You will not find any references in each individual article to the rollout because both magazines, Car & Driver and Road & Track use convention based on measuring 0 to 60mph times with a rollout. My previous posts and posts by others had links proving this.
On ice cars you pay 25% vat and then 180% registration tax in Denmark, that is why you get the big difference. Tesla being able to sell the P85D without registration tax of 180% does not give them card blance to claim whatever they want and then deliver different.
The Audi upgrade is nothing similar to 85D to P85D, with Audi you get what they sell you when it comes to performance! And on top of that you get a very different looking car. So in that aspect it is the Audi that is the bargin.
With both Audi RS7 and P85D you are getting an 0.8s improvement in performance. Astoundingly, with P85D you can use this performance on loose or slippery surfaces, as it's drivetrain response time is two orders of magnitude (yes, 100 times) quicker that the RS7 - miliseconds vs. tenths of the second. P85D is several times more efficient, can seat 7 vs, 4 in RS7, etc, etc, etc.
To a consumer, as yourself, it is irrelevant where the savings come from, for anybody trying to get serious improvement in performance P85D is a bargain of a lifetime, as you can get identical bump in performance 3.27 times cheaper than in Audi.
