With all things said and done I'll be very happy running 11.0 or 11.1 with 'only' 536 hp in my 2.2 tonne fully optioned P90D.

Hang in there Ames, I really do believe you will see MotorTrend's numbers with your car at some point in the (near) future.

I agree. [FONT=&]Tesla exceeded every 1/4 mile ET they promoted, so I believe they'll do the same with their 10.9 promotion. Personally, I'll give them 0.1 sec and [/FONT]until the end of January 2016, after which I expect my hand to be holding either a drag strip time slip showing 10.9X or a $10K refund check.[FONT=&] It's hard to imagine that they'll leave me empty-handed.[/FONT]

I hope for your sake, and Tesla's sake that you are correct. I actually think that you are (with respect to the time, not the check.) But as to the "hard to imagine" part, I expect there are a few P85D owners that wouldn't have any difficulty whatsoever imagining you winding up empty-handed.

I appreciate the link.
This is not a criticism, but I just want to point out that there are no "new" tests in the article referenced. We've already discussed the drag strip runs written about in that article in this thread.

For those with a VBox and access to P85Ds and P90DLs can you help me with a conundrum?
The P90DL I drove felt quicker to me then my P85D (which I drove to the test drive). I did not launch the P90DL but did specifically reproduce a few 30 mph plus sprints and the P90DL felt quicker. Without a doubt, the side by side 1/4 mile runs looking at VBox data shows that the P85D and P90DL accelerate about the same over the 30 to 40 mph point. The only way I can reconcile my experience with the P90DL and the VBox data is to assume Tesla is doing some energy management whereby they allow a given amount to be pulled from the battery before throttling power draw back. If the 90DL uses its available energy budget over the 85D in the launch, there is nothing available (over the 85D) above 30 or 40 mph. If you are running along at 40 mph and then use the energy, it felt to me like there was more punch to the 90DL. Regretfully, I do not have something like VBox data to back up my butt dyno. By chance can someone do some tests as described above?

I did a chart (60-100 mph calculated myself). The P90DL in current configuration does have 0.2 second improvement in 60-100 over P85D. The P90DL tested by Motor Trend even more at 0.45 second over current P90DL.

That makes sense but my butt gave me the impression it was a bit more. Granted, butt dynos are notoriously unreliable which is what got me thinking along the lines of available surge energy from the different variants. I would be interested in 40-100 for both the 90DL and P85D starting from a steady state 40 mph. My suspicions are that the 90DL will perform disproportionately better in this scenario. If I am right, it would start to shed a light on how Tesla is managing energy and further differentiate BeV from ICE.

[FONT=&]Lola,
Repeated below is a post I made on another thread. It addresses what you are investigating:
Concerning performance over 30 MPH, there is one little-discussed P90DL spec that is the most applicable. It may also be the most ambitious spec Tesla continues to put forth on the design studio: "Time to 155 miles per hour is now 20% faster than a standard Model S Performance".
[/FONT][FONT=&]I don't know how long it takes a P85D to go 0-155 but a 20% reduction would require a big increase in HP consistently delivered to the wheels throughout a wide range of speed above 30 MPH. [/FONT][FONT=&]To put this "20% faster" in context, the 1/4 mile time of 10.9 is only 6% faster than the 11.6 that P85Ds normally run. The new battery-limited 532 HP is only 15% more than 463 HP.[/FONT]
[FONT=&]Unfortunately 0-155 will be difficult to measure and verify, unlike the numerous drag strip time slip and Vbox postings here on TMC.[/FONT]

Yesterday I went to Irwindale Speedway to time my P85D so I can have hard facts when the Ludicrous update comes out. I was pleased with the results of 1/8 mile 7.370 @ 93.04, 60' in 1.652, 330' in 4.744 @ 79% charge. Another run was 7.372 @ 93.18. These times compare favorably with others that I have seen. The track is only 1/8 mile so I don't have any 1/4 times. The tech inspector said he liked Teslas as he makes money on them. His story was that a Hellcat owner was bragging that he can beat any stock car so they made a $100 bet and then a Tesla smoked the Hellcat and he was $100 richer. Unfortunately I did not see any Hellcats or Corvettes but had no problems with stock cars.

In the quarter mile, with a perfect launch I believe a hellcat has a chance against a P85D. But on a 1/8 mile track I think that was a complete sucker's bet!

Just updating with new data since Dragtimes took delivery of a new car (a little bit better in the 0-100, but still not the "fewer than 7 seconds" Motor Trend's car got):
| Version | P85D 6.1 | P85D 6.2 | P90DL (9/27) | P90DL (11/26) |
| 0-60 MPH | 3.14 | 3.05 | 2.85 | 2.86 |
| 0-100 MPH | 8.303 | 8.13 | 7.7 | 7.56 |
| 60-100 MPH (calculated) | 5.163 | 5.08 | 4.85 | 4.7 |
| Version | P85D 6.1 vs 6.2 | P85D 6.2 vs P90DL | P85D 6.2 vs P90DL 11/26 |
| 0-60 MPH | 0.09 | 0.2 | 0.19 |
| 0-100 MPH | 0.173 | 0.43 | 0.57 |
| 60-100 MPH | 0.083 | 0.23 | 0.38 |
