They wanted a motor the Japanese drivers would be used to for the performance driving in the movie, also its a good time to take the word GOD out of this argument since we all know its bull crap and just about the money and how quickly they could get a bunch or rice cars for the movie with whatever drive lines since we all know that Fast and F movies really don't talk about motors are much as how they are going to get into some rich Italians car mob for hiding money.
