I think $40k is too much of a delta in cost for content from the base model (making some assumptions) as some others previously guessed and leaning towards the $20k or so.. delta as some suggested.
So this is my life designing and manufacturing cars, working on piece costs, many of you surely would not want to know what cost the OEM buys parts from the supplier are and then the mark-up.. These guestimates are based on low volume and an opinion... done a bunch of high end stuff in my career too, designing cars (with lots of carbon fiber) that cost upwards of $600k to $2M each (full carbon fiber chassis, etc..).
If both have carbon fiber clamshells, price difference to manufacture would be $100~. Only difference is that the hood has more openings more plastic grille inserts and a bit less carbon fiber than the base model, each plastic grille insert would be around $20 each plus assembly labour. A bit more complexity in the the carbon fiber tooling if there's some undercuts, but tooling cost would be very similar. Total clamshell cost from the supplier, would guess around $15k. It would use the same hinges / latch hardware.
Extra exposed carbon fibre parts, like the rear applique, guessing would be around $2k compared to molded plastic which would be around $150. The side diff cooling inlet ducts, guessing probably around $400 each in exposed carbon fiber compared to plastic that would be $30 each. One thing about additional exposed carbon fiber cost is the clearcoat. To meet the OEM specs of UV exposure durability, the clearcoat for exposed carbon fiber can cost a couple thousand a gallon, yes, it is that expensive. May as well add another $2k in other misc. exposed carbon fiber parts not knowing the content details.
Powertrain, is it the same?, if so no difference in cost, maybe some add on cosmetic bits, carbon fiber covers or whatever, maybe add another $2k to be safe if they change / add some functional stuff, different intake ducts, air boxes, exhaust or whatever..
Suspension / brakes, guessing a 3 / 4 way adjustable shock / damper setup, probably costs $2k from the supplier for all 4 corners assuming non-adjustable for the base model. Then brake rotors, will they go carbon ceramic is an unknown? (guessing yes)
Miscellaneous, guessing.... interior carbon fiber stuff, alcantara, wheels, carbon fiber x-brace, splitter, fog lamps, coolers, brake ducts, grille accents, etc.. tack on another $10k, and a unique heritage marketing mark-up fluff at minimum of another $2k just because it's a limited / special model.
In the end, I bet that the delta is going to be around $20k+.. overall (price difference) will be $110k for the base model to $130k (may be a bit more if they go with CC brake rotors). If anything less for either; I will be extremely impressed (due to the low volume production numbers), also need to note that this guessing is based on a volume over a projected number of years, and guessing that this Gen V model will be in production for 5 years minimum to compensate the investment in tooling..
Cheers,
Mike
PS.. have to emphasize that it's a damn good deal IF that's the price range compared to the previous generations with SMC panels, having aluminum doors too, it is a very good deal for either the SRT or GTS compared to the supercars that I previously worked on / designed...
