convertible vs coupe (weight)

So I read somewhere that the convertible cobras are heavier than the coupe, does anyone know for sure? If so, then anyone know how much more and what accounts for the added weight?

convertibles weigh more than coupes, due to weight of top & mechanism, plus additional frame stiffening elements usually added.
The 2010 conv. loses ~6 cu.ft of total interior volume (cabin and trunk) compared to coupe too.

2007 Mustang GT Coupe curb weight (lbs) 3,351
2007 Ford Mustang GT Convertible curb weight (lbs) 3,613.

Careful passenger selection will equalize any perceived difference, and ragtops can be more selective

I've always heard 150 lbs more for the vert.

Sorry i only answered half your question. Verts don't have the structural rigidity of a coupe since the roof is not there to support the rest of the body. Engineers have to strengthen the chassis on a convertible by adding chassis strength throughout the body (more weight). It seems like the opposite should be true (no roof- less weight) but it never has been. The same is true with cars like vettes. Ever notice how heavy a vette is despite being bodied in fiberglass? All the structure has to be built into the chassis since the body can support no weight.

thanks pliskin. I kind of had an idea that the extra weight came from structrual reinforcements but didnt know how much extra weight came from this.

Also, do you think that excessive wheel hop is due to the loss of structural stability?

No the wheel hop comes from the sucky rear end engineering...get some aftermarket upper and lower control arms, some new springs and toss the "quad shock"...no more wheel hop!

I don't think a Vette is that heavy at all. They are lighter than a V6 Mustang and have twice as many features and twice the engine. lol
