On the subject of EV weight …
It's clearly true that EVs are heavy. If you can do a direct comparison with cars that are sold with either internal combustion or electric engines, it's obvious. Most of the extra weight in EVs is from the batteries.
When I was shopping, I narrowed down my choice to the Volvo C40 that I bought, and the Tesla Model Y. Both come with 75 kWh batteries and AWD with two electric motors. Yet, the Tesla's range is said to be 325 miles, and the Volvo C40 or XC40 is 225 miles. Why? It seems the difference is due to total weight. The Tesla Model Y's frame is made of aluminum, with a fair amount of plastic, while the Volvo has a heavier steel frame, responsible for it's relative crush-resistance. I don't know for certain if that is the only reason for the range difference, but I think it explains a lot.
Interestingly, a Tesla sedan (unknown model … perhaps a Model 3) recently was in the news because it went over a steep cliff a bit south of San Francisco. It fell about 250 feet, crashing onto some rocks below. Rescuers were surprised to find that all 4 occupants – 2 adults & 2 children – survived. Most similar crashes result in death for all inside. What about that Tesla might have contributed to that? Certainly, the bottom heavy placement of the heavy batteries had something to do with that. The car landed on it's wheels. We'll find out soon enough, if there is greater inherent strength to that Tesla EV's frame.
