Just picked up my wife's new S70D. There is a forward production change mostly due to the dual motor S losing most of the frunk space, and also losing any reasonable access to the space under the trunk floor (the fuzzy mat does not remove easily). Originally there was a space/compartment under the frunk floor in non-D cars to stow a tow hook. Many early Model S however did not receive the hook, nor was there a threaded receptacle behind the nose cone to thread it into even if you had one. My May 2013 S85 does not have a hook or a receiver. What TM has done is revise the black mesh UMC tote bag. It has a separate side zippered compartment which contains/holds the tow hook (nicely done pocket and Velcro to hold it securely). I assume all new S come with this UMC/tow hook setup. The problem for me is that I leave the UMC plugged into the NEMA 14-50 at home and keep the black UMC bag hooked over the cord holder. Thus on a routine local daily basis, we do not drive around with the UMC bag in the car. Thus, for my wife's S70D, I put the tow hook into a separate bag inside the frunk, so it is always with the car.
