Where did the S85 data come from?
These numbers definitely invite analysis.
At first glance, the dual motor cars all must have insane 0-30 (I can only estimate, since we don't have those numbers).
The assumption of course (and I am sure everyone can agree), the higher the speed, the slower the acceleration (except the very beginning for single motor cars, due to traction).
Let's look at the P85D:
In the 20 miles from 30-50, it uses 1.15 seconds, while 50-70, it uses 1.65 seconds. We can reasonably assume that 50-60 took 0.75 while 60-70 took 0.9. Under this assumption, 30-60 would have taken 1.9 seconds, which means 0-30 happened in 1.15 seconds, which would make people feel amazing acceleration, maybe almost being kicked into their seats (this is where G most certainly exceeds 1 or maybe even 1.1 or 1.2, not sure since I have not seen a G chart, and people feel the insaneness that we have all heard about).
Now let's look at the 70D:
30-50 took 2.0 while 50-70 took 3.1, so let's estimate that 50-60 took 1.4 while 60-70 took 1.7. This means 30-60 in 3.4, which translates to a 0-30 in 1.7 seconds, although not insane, but still amazing by almost any ICE car standards.
For P85:
50-60 in 0.85 and 60-70 in 1.05, then 30-60 in 2.25, and 0-30 in 1.65. (you may be noticing that basically I am assuming that 60-70 takes about 20% longer than 50-60 in all cases).
For 85 (assuming data is correct):
50-60 in 0.9 and 60-70 in 1.1, then 30-60 in 2.6 and 0-30 in 2.4 (this makes me feel some of the numbers for the S85 are suspect, the mid range acceleration is too fast, while the 0-30 is too slow, since it should have less traction problems than the P85... so although it should be slower, it shouldn't be 0.75 seconds slower.
I think the 70D, P85D, and P85 all came from pretty authoritative sources, so basically it means all the dual motor cars have amazing 0-30 accelerations. However, the 70D has only normal performance sedan mid range accelerations, while the P85D and P85 maintain top level sports car mid level accelerations.
