Motor Trend's "Worlds Greatest Drag Race 7" (2017) saw the Tesla S take 1st over a field of Porsche, Ferrari, McClaren... ([URL="http://www.youtube.com/watch?v=cvk18vx-nrY"])
I get it, if the race were longer than 1/4 mile, they'd have overtaken but still, a 911 Turbo S lost a drag TO A 4 DOOR SEDAN!!! And that's from technology that's clearly in its infancy. Can you imagine if Porsche put proper suspension, brakes, and cockpit around torque like that?? Oh my god I can't wait.
The answer is always both.
