Once volume production is achieved, at pack level LiFePo 4680 will be less than $55/kWh.I previously posted in this thread that it might be possible with the new production methods to reduce the cost of the M3 possibly down to $25k. I also mentioned the cost of the battery being a substantial barrier to achieve this, however, on another thread I did some numbers like this:
According to Cairn Energy a Tesla 2170 cell battery pack costs around $156kWh.
If a 4680 is 56% less cost it would be around $87kWh.
The largest 82kWh battery in a M3 would cost $12 792 in 2170 cells.
That same 82kWh battery would cost (82x$87kWh) $7,134 in 4680 cells.
That means switching to a 4680 cell pack could cut $12792-$7134 = $5658 off the manufacturing cost of a M3 LR. It would be less for a SR. A 4680 pack would also be considerably smaller and weigh less, so the kWh pack capacity would probably be less too for the same range.
Is it possible to reduce the manufacturing cost (not retail cost btw) another $4-5k to reach a $25k retail cost by using castings etc? I think it should be, we're more than half way there with a 4680 pack alone.
A $25k M3 would be fantastic. Let alone when the infrastructure bill comes through. .
