The difference isn't much, it is pretty cool that the sedan is lighter though.

I still dont understand the manual being heavier, I really feel like that is a mistake.

 

It's the extra pedal

 

Gives me a little bit more confidence when sitting next to a coupe with my '04 sedan at a redlight.

 

I was always in denial that the coupes were generally heavier than their respectable sedan. I'd like to know what areas the coupes picked up the extra weight

 

The extra weight comes from the added support the coupe doors need since they are so heavy.

 

the infamous coupe doors...

 

The coupe is wider than the sedan.... then again the sedan is longer than the coupe then it is narrower. So...

 

yea i think it all pretty much comes out in the wash. they have their differences but realistically its only 40-50 lbs between respectable coupes and sedans anyway.

 

The hatchbacks on coupes are pretty heavy themselves on most coupes , have you ever lifted one with the struts being out? They frame is pretty duty to hold that large of a piece of glass and since there is a really large opening in the unibody it has to have additional reinforcement for sure in that area.
On top of that the coupes have a heavier lsd differential and if you have Brembos with larger rotors then there is additional weight there.

 

But if you've got a 6 MT Sedan like mine then your VLSD is exactly the same as the Coupe.

Also, some good theories here behind why the Coupes are heavier and I certainly don't know for sure, but generally speaking 4-door sedans are ligher than their coupe brethern because metal is heavier than glass and there is more metal in the roof of a coupe than there is in the glass greenhouse of a comparable sedan (the B-pillars are wide swaths of steel in a coupe where the 4-door has narrow B & C pillars, etc.) I know this is true for other cars & models, but don't know the specifics of the G35's. But just take a look at the amount of metal in a coupe roof and then notice how much less in a sedan roof.

Just sayin'....

 

i had my 04 coupe weighed with 1/2 tank of gas with out me. it is 3600 LBS

 

That doesn't sound right, it should be lighter. Do you have a sound system?

 

03-04 Leather - 3422
03 - 04 6mt - 3435

+ 50 lbs (approx half tank)


Interesting

 

The curb weight of a vehicle includes a full tank of fuel.

 

Oh cool didn't know that.
