This isn't the only head to head with the P85D. I've see no news where life lamboghini and Ferrari cars are readily beaten off the line,,just to catch up,after some point.
Batteries can make amazing current when shorted or near shorted, because their impedance is so low. Thermal capabilities of keeping that up aren't quite so great.
IMO the hybrid of one sort or another, likely biasing more and more like the Chevy volt, is what we will see. And from there, then bias the drive motor and batteries toward performance, or not.
I suspect that electrically enabled awd (ie electric drive one axle, mechanical on the other) will start the be the next big thing, as auto makers can sell more hybrids and bring up CAFE, while selling value added AWD that many people want.
