Chevy Suburban: ~ 5,700–6,100lbs

Model 3: ~ 3,860–3,900+ lbs

Suburban is about 1.5–1.6× heavier than a Tesla Model 3.

The Chevy Suburban has been one of the largest vehicles on the market since 1934. [1]

If you wanted an EV to match the Suburban it would probably be that Cadillac Escalade IQ in terms of size, comfort, and towing capacity -- that's got a curb weight of 9,100 pounds which is 1.5x heavier than the Suburban.

I'd think the BMW 3 Series has a similar vibe to the Model 3 and that has a base curb weight of 3536 which is about 10% less than the Model 3.
