What makes the Crosstrek so heavy?

I was wondering what makes the Crosstrek so heavy? The body has a lot of plastic. Is the interior particularly heavy? Drive train? The fb20 is not a fast engine by any means but is it a heavy engine? Generally just curious why this car weighs so much considering it's size.

Is it that heavy? Seems at par with others in its class, +/- 50 kg
Crosstrek: 3300 lbs
CX30: 3400 lbs
Corolla cross: 3100 lbs
HR-V: 3200 lbs
Kia Seltos: 3200 lbs
Jeep Renegade: 3200 lbs

Boxer engines are inherently heavier, since you have two engine top-ends. The front end of the car is also longer to fit the engine, as opposed to an inline-4, which adds to the frame/body (even a few inches make a difference in weight).

Basically, cheaper materials(IE steel instead of more expensive, lighter weight ones), not engineered in that direction, production cost limitations, etc.. I disagree on the flat engine comments, as our Boxster is 500 lbs(at a minimum) lighter than the Crosstrek. It feels every bit of it. Government and insurance regs/pressures have made vehicles heavier over the decades.

You're right about the materials ans regulations - but it doesn't negate the fact that, for the exact same displacement and metal composition, a H4 engine will be heavier than an I4, IMHO. Just from the fact you have two top-ends (heads + valvetrains). The overall "cube" of the engine has a larger surface area = more metal.

The weight of your boxter is not an argument, it's comparing apples to potatoes..

It's due to phenomenons called ever-increasing vehicle dimensions, government mandates, strength of materials and gravity ... ;).

Using 1970's/1980's passenger car standards, today's Crosstrek would be considered a morbidly-obese, mid-sized, 5-door hatchback with hairy legs and unshaven armpits.

I got a little bit of a chuckle out of this thread, because the original assumption behind it was shown to be inaccurate ... but that didn't stop anyone from continuing to explain it!



If you look back at cars from the 60s and some earlier decades, the Crosstrek is actually a pretty lightweight vehicle ... the Chrysler I drove back in college was close to 4,000 pounds, for example. The energy crisis of the 70s was a big factor in starting to reduce car weights, but that trend was offset in recent years by America's desire for ever-larger vehicles. Those giant modern three-row SUVs and massive pickup trucks are the things that should be called morbidly obese -- compared to most of what's on the road today, the Crosstrek is pretty svelte, which is one of the reasons I bought it. And considering its safety and capability, I'd say it's a pretty remarkably efficient use of weight.

So the hood on my Crosstrek is pretty flimsy compared to a rental Mazda CX-5 we had at work.

Granted it was turbocharged, so the hood had insulation, but that hood was pretty heavy! And checking Google, the CX-5 weighs over 3700 pounds. Which makes my Crosstrek pretty light in comparison!
