Here's the original article that discusses Tesla's current battery pricing
UBS Sees Telsa's (TSLA) Model 3 As Unprofitable
Basically, Jon Bereisa who was the chief engineer of the Chevy Volt estimated that the Chevy Bolt's battery pricing to be $210/kWh at the pack level, based on $145/kWh at the cell level. Obviously, he knows GM's and LG's costs the best. He also estimated that Tesla's Model 3 pack costs would be $260/kWh. Of course, he doesn't know Tesla or Panasonic costs at all. So Jeff Evanson of Tesla Investor Relations calls in and states that the Model S's all-in pack cost is already under $190/kWh.
There is some contention on SG&A, R&D, and other items to sort out costs. What the UBS analyst and Mr. Bereisa don't seem to understand is that the Gigafactory won't have typical supplier markup.
In any case, for gross margin purposes, Tesla's pack cost is under $190/kWh now. Even at a modest 20% reduction with the Gigafactory, the cost would be $152/kWh.
Therefore, a 60 kWh Bolt pack would cost GM about $12,500.
A 55 kWh Model 3 pack would cost Tesla about $8,500.
A difference of about $4,000 on vehicles that retail for the mid-$30k's is a lot. Margin at these price points is very slim. However, GM's pricing for the rest of the car is likely far better than Tesla's pricing. Basically, the pack cost advantage is one of the key parts where Tesla makes up ground for their lack of manufacturing expertise at a grand scale.
