Hard to find exact numbers but it looks like the average SUV weight is 2100kg. Here's five Tesla models:
Model X Long Range – 2459 kg
Tesla Model S Performance – 2241 kg
Tesla Model S Long Range – 2215 kg
Model 3 Performance – 1847 kg
Model Y Long range - 2003 kg
Average: 2153
Not much difference. Naturally if you factor in gasoline sedans etc. that brings the average down. But same for EVs if you drop in the lower priced models.
