Long range rear wheel drive here. Number 4xx off the assembly line. It's hard for me to quantify how much I enjoyed this update without sounding dramatic. I came from a P85DI Model S and have a performance automotive background. I've always loved fast cars but found the speed of the P85D to be somewhat excessive, even by my standards. I bought the LR 3 knowing it was fast enough.
And it's gotten faster on me. This car is crippled off the line intentionally and that's still the case after the update. So I suspect the raw 0-30, 0-60, etc aren't going to look that much better. Where the car shines is any kind of roll. At almost any surface street speed it feels notably more powerful. It's not night and day but you're waking up with more power than you had yesterday. Who can complain?
Likewise with stop mode. It's the feature I never knew I wanted until I used it and now I can't imagine driving the car without it. I think my only complaint there would be that it was slightly more adjustable. I feel like there are still too many situations where I need to hit the brakes to get the car to slow down at a faster rate than regen is providing. In my ex wife's old i3 you could truly one pedal your way basically to a stop, quite quickly. The Model 3 still takes its time. All in though, this little fraction of an update is bigger to me than V10 was. I love it.
And since I don't see any LR RWD owners posting, to those wondering, yes your car is going to feel faster.
