Edit: turns out my car weighs even less.
Edit2: asked Google for most common, seems Tesla Model S at around 2100 kg.
Rav 4 - Model Y is a good comparison to capture the extremes. Lexus Rx 350 is 4200lbs for their base trims.
Toyota Camry, 3300lbs. Model 3, 4000lbs. 20%
If you want to provide a like for like example go for it. But it has to be a like for like, not a Toyota Yaris hatchback vs a Model Y.
Not sure why you are clarifying what a like for like comparison is. I am making the point that you have a cherry picked 40% example, without backing up the models and I am giving you like for like comparisons where its 20%.
Model x 5400lbs, BMW x5 4800lbs. 12%
