The setup looks similar to the Cadillac XLR and CTS no?

If it is the same, can we expect it to flex as much as they do under load?

The CTS and XLR toe out a lot under load.

 

from what everyone's been hearing, it's not a form of the Sigma chassis. the Zeta platform has risen from the ashes.

 

So it will be a completely different, and stronger, axle?

 

When you say "axle", are you talking about the differential or the suspension design? Also, the CTS and XLR use completely different systems. XLR's rear end is basically the Corvette's rear-mounted transmission setup, and CTS is the Sigma chassis.
