Unfortunately the test car is an AWD model, and that really hammers the result. I recall when straightpipe did a video on the TT LS with AWD configuration, they did mention the AWD system always keeps the leash on you for having any sort of fun or getting out of sort. I'm very curious to see how a RWD model fares on the same test track. The body motion looks totally in control to me, so the cause of the low speed really comes down to heavy understeer (and partially, the weight is to be blamed too). The recent savagegeese video inspects the underbody of the facelifted LS, and he commented on the platform sharing most of its resemblance from LC, except many of these components were made in steel instead of aluminum. I feel like they shouldn't save the cost on a flagship model, as it is currently the heaviest vehicle in its class and the weight penalty does hurt in test result.
