I'm not single, a car expert or a doctor but I play those roles on the Internet.
So I am thoroughly confused at how Tesla can sell the Model 3 at $35,000.
Here are the things that make a product cheaper:
1) Lower cost materials - the Model 3 uses steel, cheaper than aluminum, so that may reduce costs
2) Lower amount of material - a 5 lb product costs less than a 7 lb product to make, so maybe the Model 3 weighs less
3) Easier to assemble - no advantage here, the Model 3 looks to have the same parts and construction as the MS
4) Lower overhead - no advantage here, the Model 3 is assembled with the same labor in the same place as the MS
Things that make a new product more expensive:
1) New design - since the Model 3 isn't a crippled MS, so it needs:
a) New chassis to design, fabricate and test for safety
b) New battery pack to design, test for safety and design software for
c) New sheet metal - nothing ported over from the MS, not even the door handles
2) Expensive materials - the pano roof on the Model 3 that gives headroom has got to be insanely expensive
I shall email Elon and advise the new Model 3 be re-evaluated in the marketplace to a $60,000 car.
