Just because you can take a P85D and drain its battery down to 50% SOC, against, for all I know, a pre-warmed, fully charged 85D, and still lose in roll-on, doesn't say whole lot.
Voltage drops with discharge. Maybe we should revisit how batteries work?
I think you misunderstood my point here. Both car had been charged to 90%... Then we followed each other for close to 200miles (road trip). I'm not saying that the drop in power is a problem, I understand the math behind it... I'm just saying when you compare the real life performance of a P85D vs a 85D, the difference gets smaller and smaller as SOC% (of BOTH cars) gets down.
Example (bogus numbers)
Both cars at 100%SOC : P85D is 30% faster 0-60 and 15% faster 60-80
Both cars at 60%SOC : P85D is 25% faster 0-60 and 10% faster 60-80
Both cars at 40%SOC : P85D is 20% faster 0-60 and 5% faster 60-80
Again, these are bogus number, just to illustrate what I think we are seeing here.
You get what I mean? While both car gets slower along with SOC, as expected (100%normal), the P85D loose its margin, especially at higher speed. Speculating here but I guess the new smaller drive units have a less pronounced HP drop as RPM ramps up.
That's what I meant. In any cases, 0-30 of the P85D totally destroys a 85D, event if the P85D is 30% and the 85D is 100%... but then, in that case, it's more of having more power where it matters most at those speed : on the rear axle. I can feel my front tires slipping under heavy acceleration. The P85D I tried did not do that, probably because the rear motor has more power and so is able to "push" the car as much as the smaller motor up front is "pulling" it.
