Were sport, coupes the only Gs of our era to come with the LSD?

 

Generally, yes, at least where the term "sport" includes the actual Sport model (i.e. 6MT) as well as the Journey (i.e. AT) with the Sport option included. The only exception to this is on the 2012+ G37X coupes, where it was included with the Sport option.

It lets you look up every model, in every year, and then tab over to the "specs" tab and see all features and options.

 

This is interesting. So does this mean the VSLD is swappable into the g37x sedan? There was a thread there that the Diff fuse would need to be pulled if doing so, or maybe I am thinking of gears?

 

Cool website! Thank you for that link!
