Beachstartup is right, I was being over-generous in my characterization when I said "on par". I really meant for the kind of driving you'd do every day, the cars are on par, but in raw performance, cars like the M5 and C63 AMG absolutely destroy the Model S P85+.
That video is a fluke. In (instrumented) test after test, the M5 is over 1 second faster 0-60, and more than 2 seconds faster down the quarter mile. That might not sound like a lot, but imagine a car drives by at 100+ MPH, now count...
one-thousand-one
one-thousand-two
How far down the road is that car now? That's the distance between an M5 and a 85P+ in the quarter mile.
There is a realm of performance at the very top end where the dino-powered engine still has an advantage. Electrics can achieve the same performance, but you're fighting an up-hill battle to get there. You have to make too many compromises along the way [1] in order to beat them. Right now, at least. It'll be slow coming, but I believe the transition to electric advantage is coming.
1: Here's an example of an extremely compromised all-out electric that is capable of beating its petrol powered equivalent. Have a look at 3:35 ish for a drag race. https://www.youtube.com/watch?v=5gFGX43vubM.
