I have some performance driving experience. When I tested the Model Y, I was concerned that it wouldn't be sport enough for my tastes. Coming from perspective of someone with track training enough to know that I will never be a really good driver, I drove the cars back to back. I was then given the chance to take a MYP home for the night.
Clearly, the MYP has stiffer bushings and higher rate shocks. The springs are the same, which is irrelevant, as they are too stiff on both cars. The MYP will take a set into a corner quite a bit better, and has much better control through transitions, while the LR, while never wallowy, is a little softer in transitions. The MYP also has quite a bit more functional acceleration throughout the range. Brakes seemed similar, but I would like a little bit better brakes if I would track the car.
Overall, the LR drives great, but the MYP has clearly been sorted out in tuning. What it really needs is a Track Mode.
For me, I like the MYP because it suits me better, but I agree with everyone here in principle, because unless you really like to enjoy the feel of pushing a car a little bit, the LR gives you more than enough to blow away anything in it's class except the X3 M or an AMG GLE 63 S.
