Engine size and Economy
Will engine size effect the cars economy/mpg. Like a 1.4Lv and a 2L Inline 4 that have the same economy in engine designer/Dyno, if put in the same care will they both get the same mpg or will the 1.4L version get better mpg since it's smaller. Also will we be able to sell engines to other car companies like how we can buy engines from other companies.
