GM has already stated the price for their high end Silverado EV, 400 miles range at 647 hp (same 212.7 useable kwh battery pack as the 329 range Hummer but a lighter more aero vehicle) will cost $107K. GM product has been expensive for years however.
The 500 mile range CT will in reality be closer to a 400 mile range, and will likely get by with a bit smaller battery pack than the Silverado-E because it'll weigh 1K#s less, have less content and be more aero. But still, why would they price it significantly less than the Silverado-E?
Ford claimed batteries cost above $200/ kWh so using that math a 180 kWh CT battery pack alone would cost $36K.
The CT realistically would cost considerably more to manufacture than a MY.
I hope that I'm wrong, but I don't think a nicely speced CT can be the $39K that Musk initially indicated. But heck the Lighting MSRP is $39K so I guess we'll see.
