Just curious what you guys think where the additional weight is coming from vs. the previous generation....or any sedan for that matter. I understand that stronger components have to be installed to handle the power, but 4300 lbs is alot of weight!!

The new car is wider than the old one and was built to handle the LSA's power from the get-go, so everything that has to do with putting that kind of power to the ground without grenading or twisting (drivetrain, monocoque, etc.) and then converting all that energy to heat to bring it to a stop over and over (brakes, wheels, tires) had to be beefed up (not to mention the supercharger and associated components) and crash standards for at least the next 4-6 years have to be met in every market they're going to sell it in, all while keeping their cost (manufacturing, repair, etc.) targets in mind.

562 lbs for a differential?!? That's impressive. Can you provide a reference?

Oh, well I did find this differential that weighs 550 lbs so I guess it's not impossible.

I don't know the physical dimensions of the CTS-V diff, but even a solid one foot cube of cast iron doesn't weigh 550 lbs!:hmm:
