Lots of vehicles have less crush strength than the Model 3, and most of them don't have glass roofs. If you recall... the NTHSA testing of the Model S literally broke their machine. The NTHSA said the Model S had the best rollover test (top impact from their machine trying to crush it) of anything they've ever tested.

To really answer your question, I've arbitrarily picked a few common vehicles with metal roofs.

The IIHS says the Civic roof withstands 13,195lbs of force: https://www.iihs.org/ratings/vehicle/honda/civic-2-door-coup...

A Subaru Outback: 18,533lbs of roof strength: https://www.iihs.org/ratings/vehicle/subaru/outback-4-door-w...

A BMW 3 series has roughly the same roof strength as a Model 3: https://www.iihs.org/ratings/vehicle/bmw/3-series-4-door-sed...

An Audi A5 is only 16,327lbs of roof strength: https://www.iihs.org/ratings/vehicle/audi/a5-coupe-2-door-co...

You get the idea!

One moment you missed. Electric cars are very heavy, and their centres of mass tend to be right below the cabin.

Having very strong pillars is pretty much a prerequisite for surviving a rollover in an EV.

Most people tell me the BMW 330i is very comparable to a Model 3, and its curb weight is 3,582 to 3,764 lbs (per BMW). The Model 3's curb weight is 3,627 to 4,072 lbs (per Tesla).

That isn't as big of a difference as I'd have expected.

Engines and transmissions are also heavy.

[moduspol]

They're not all that heavy any more.

The Tesla Model 3 is 3552-4072 lbs, while the new Jeep Wrangler (JL) is 3955-4455 lbs.

I think it's more of a "relative" to certain cars.

I could compare it to a miata that is ~2300lbs. But that's not really relevant then, is it? A Jeep Wrangler is basically a truck - so I don't think that's a good comparison.

Compared to other "compact executive cars" (as its class states) it's close to the competition.

[moduspol]

Well, I mention it only because I get the comment a lot and my last car was a (two door) Wrangler. You could compare it to trucks, but it's just not perceived as a particularly heavy vehicle even relative to normal cars.

The vibe I've got from talking to people is that they think the Model 3 (or Teslas in general) are significantly heavy relative to normal consumer vehicles. It's pretty surprising to them that even a 2 door Jeep Wrangler is actually heavier.

[bradlys]

I think most people would be surprised just at how heavy a Jeep Wrangler is to begin with. Without even comparison, most of the 2-doors don't look like they'd be that heavy.

Same with my 1-series. It's obscenely heavy for how small it is.

[moduspol]

Yep. Exactly my point, although honestly it didn't occur to me that the weight of the Wrangler might be an outlier.

Suzuki Mehran dry mass is around 550kg, and it's made of steel, not aluminium.

A more spacious Alto that uses some aluminium and magnesium is around 650kg.

Talking about "not-so-heavy" cars...

[DuskStar]

> Suzuki Mehran dry mass is around 550kg

That's a Pakistan-only car with no safety features [0]. (From the Wikipedia description, "a car with everything manually operated, and with no safety features. The car lacks airbags, ABS, rear window defogger, side air conditioner vents, seat belt reminder and even rear seat belts.") So yes, it's light. You'll also immediately die in a collision, but you get what you pay for I suppose. (The Alto is sold more broadly, but it's still obsolete)

Not exactly comparing like to like.

The Model 3 is ~25% heavier than Ford Fusion.
