The Audi is 3,527 lbs, where the Model 3 is 4,048 lbs. The Tesla is a bit longer and narrower, but they're both big cars.

The Rav4 FWD is 3370 lbs, where the Ionic 5 standard range FWD is about 4,000 lbs (the SEL is 4,300).

If the best examples are "only 500-700 lbs heavier" I think there is still room for progress. Rounded, that's the rough 1000 lbs I suggested above.

Electric cars are, in aggregate, simply heavier right now— with implications for crash safety for everyone (especially those outside that vehicle). Any progress toward increasing energy density (and vehicle size) will confer a net benefit to society.
