Interestingly my BMW i3 has actually gained a little range after two years. But BMW ships it with a buffer as there is a 22kWh battery of which only about 19kWh is available. That's also why it has full regen at a 100% charge. Sort of like owning a 60D that comes with the 75kWh battery.I know the feeling. In my case I didn't know if it was the algorithm or degradation. It's probably a little of both. The good news is that it starts to stabilize.
But Telsa always wants to over promise and under deliver. When selling the car, they promote 294mi of range. In reality, after five months, it's more like this. 256 @ 90% = 284 rated miles (RM) @ 100%. But my car drops an RM for every 273W consumed, while actually averaging 303W/mi, so in reality I get 256mi of real driving range (273 / 303 = .9 * 294 = 256) in a car that is advertised as having 294mi of range. The reality is I get 13% less range than was advertised while my BMW is getting about 5% more than advertised.
Kinda funny how the math works out that my 90% charge is also my real world driving range with a 100% charge.
