Hello, 2019 Model 3 Long Range (acceleration boost) owner here. I want to trade my Model 3 for a 2016 Model S P100D. I test drove a vehicle last weekend and the acceleration was much weaker than I expected. The car has been on the lot for 80-odd days and was at 50% charge. The car felt heavy and sluggish. My Model 3 feels like a rocket comparatively. Could this be down to the car sitting idle for so long? Acceleration flattened out around 40,50mph. I tested in sport, Ludicrous and Ludicrous plus. Another issue was the regenerative braking felt non-existent. The car is in Dallas and it was around 42F outside. Regen was set to Standard. When I let of the accelerator the car would slow down just via lost inertia but then it would coast at sub 5mph. The regen wouldn't bring the car to a complete stop. Am I missing something? These are certainly red flags; my question is should I look at another identical vehicle or is this standard behavior for this car? Could you share your experience if you've driven both a Model 3 and P100D? I'm in Washington, the car I just looked at is in Dallas and there's another car in Birmingham that I might check out. Thank you for an help.
