And the Audi is already on the heavier side for vehicles of that size. Mainstream non-'luxury' sedans of comparable size are often 3200-3300, like Accord/Camry/Altima, and the construction of these vehicles is a more equal comparison.

S3 is heavy because it has 4wd and a bigger everything compared to a lower trim model. The same as the vw golf 8 starts at 1300kg, but my R model is in the 1500 range because it has 4wd and other things like adaptive damping that make it heavy

AWD is available on the Camry for an 86kg penalty. But yes, every part adds weight. That's why Teslas have spartan interiors and less noise deadening than other vehicles in the price range, they're spending as much weight as possible on the batteries and not the rest of the car.

From Google: Model 3: 3,862 to 4,048 lbs Audi S3: 3,527 lbs

9-14% seems comparable IMO and worst case roughly half he mentioned 1000 lbs.

The difference is around 250kg. Witch is a lot for a small car. My source is adac. But if you don't go to a S3 and are OK with regular A3 with smaller engine those start at 1300 kg.

You are comparing the heaviest Ioniq to a lighter trim of Rav 4. If you compare models more similar in price the difference is significantly less.

I went to Edmunds and went with "Most Popular" from the drop down when choosing the trim level.
