After only 2.5 years of production, BMW announced a new battery for the i3 where the range goes from approximately 80 miles to 125 miles. The rumor is that they are going to use the new Samsung 94 Ah battery cells.
I have not heard anything about Tesla updating the batteries in Model S or Model x. Model S has been around since 2012 and I am sure battery technology has improved since then. Given the 250 mile range on Tesla cars, battery capacity upgrades are not on top of the list of Tesla Owners (lie it is for i3 owners who get about 70-80 miles out of a single charge).
Is there any public information on what the battery upgrade plans are?
Note: The only battery upgrade i am aware of is on the Roadster.
