> look at high-end sports cars To my eyes, there is much less shape diversity in sports cars than customer cars. Sedans definitely look the same but is it the optimal shape? > And if they make efficient, low power and cheap cars nobody will buy the powerful and expensive ones. That applies especially to different motors for a given car model. Several times, I have seen the lower-end engine, although less powerful, smaller displacement, to have the same mileage as the more powerful engine of the same technology/generation. A fellow engineer who worked in the car industry confirmed me (although not that clearly, because it is a sensitive subject), that engines for the low-end range can be sold with a sub-optimal mapping.
