First, I'll start off with the main question. Why is the Model Y AWD so much slower, 0-60, than the Model 3 AWD?
The Model 3 (without acceleration boost) has a listed 0-60mph time of 4.4 seconds, but in reality it is around 4.0-4.1 seconds after a couple of key performance enhancing software releases. Dyno tests have shown the non-boosted Model 3 AWD to have 447 HP / 397 Torque.
The Model Y has a listed 0-60mph time of 4.8 seconds and testing shows it to be around the same 4.8 seconds, even though the same performance enhanced software version is running on it. The Model Y does weight 325 lbs more, but that should not equate to .7-.8 seconds slower 0-60. The Model Y AWD reviews show it as having 384 HP / 376 Torque, so why is it so much slower than the Model 3?
Maybe I missed it, but I'm surprised that I haven't seen other AWD Model Y owners disappointed by these numbers, when compared to the similar Model 3, that only weighs 325 lbs more. I'm pretty sure that the Acceleration Boost will be offered for the Y at some point (Free $$$ for Tesla), but I would really hope that Tesla will also even out these numbers as well.
