Usually people interested in mpg also have a limited budget to purchase the car.
It would be interesting to discuss if a shorter stroke would mean less torque?
A shorter stroke generally will result in less torque because you lose leverage on the crankshaft. However, increasing the bore will allow for more pressure from combustion on the piston.

My 3.2 v6 is an 81mm stroke by 92mm bore, peak tq of 220@4400rpm and peak hp of 220@6600rpm. Decent low torque, but is pretty motivating above 4k.
