Weasel your way out of this one:
It's hard to find actual solid comparison data, comparing apples to apples. So here's what I did. Let's look at the Tesla S. It weighs 4,561 to 4,766 lbs. Then I Googled for comparable cars and found this from Autoweek:
The Audi A7 hits most of the same points of Tesla's Model S—save, of course, for its gasoline options. From pricing to sizing, Audi's A7, S7, and RS7 are almost a full analog for the battery-powered Tesla.
The weights:
A7 4332 S7 4597 RS7 4938
So if there is this huge difference in weight, one that is going to kill people via more emissions from it's tires, I'm sure not seeing it. And if it was an inherent big weight problem with batteries, then the above would be impossible, so just one good example goes a long way to disproving it. The whole weight thing is a canard, a desperate lame attempt by an anti-EV article to try to throw crap on electric vehicles. Who cares what it weighs anyway? They accelerate fast, stop fine, get excellent mileage.
