I am a new Model X owner LR+ 20" with -H battery built 9/2020. I have been looking for LR (non-performance) horsepower and 0-60 information and have not found much in the forum especially for power. I will post my findings to this thread and ask anyone else with info to chime in as well. Thanks 74% SOC in "very low", car is not hot but not cold, floored it from 30 mph. 421 kW battery power according to TeslaFi, which corresponds to 565 bhp. Assuming 7% loss to axle (Raven) this is 525 hp at the wheel, which close to the 518 hp I found on this page. Interestingly, this is the same power I measured for my P3, which is 0-60 in 3.00 1-ft rollout (beast!). I will measure 0-60 at high SOC and when warm soon and post here, seems like the best will be 4.4 sec with 1-foot rollout.
