Toyota was lazy. Thats all…
Toyota was lazy. Thats all there is to it. They could have easily developed an inline 6 of their own. Look at the GR yaris\corolla engine. Just a few years ago that didnt exist, but they found the time to make a little 3 cylinder from scratch didnt they..? The supra is the most iconic toyota vehicle ever. They ruined it by puting a BMW engine in it. There are still those who are fans of the car, but those who are actually in to car culture have rejected the new supra. Not only is it not a toyota, its not even japanese.
