So what is 10k miles of free charging equate to in term of dollars?
First of all, as Danimal mentioned, it's 4000kWh free charging, which actually works out a whole lot more than 10,000 miles for M3 or MY.
If it's M3 base, which has a 50kWh battery for a 272 mile range, it comes out to roughly 21,600 miles.
Let's take Danimal's MY LR, which has a 81kWh battery for 330 mile range, then it comes out to roughly 16,300 miles.
As for how much 4000kWh equates to, that depends on when and where you charge. As of September 29, 2022, Culver City, Hollywood, DTLA, Long Beach, and Irvine had peak rates of $0.55-0.65 per kWh. During off-peak hours, however, which run from midnight to 8:00 a.m. at those locations, the rates range from $0.21 to $0.41 per kWh. So we're looking at $840 to $2,600.
