Than what about @Spilner example? Like I said, seeing it in person is best. Camera lens can greatly distort the size of an object.
I'm not sure if you guys have seen the FT-1 blueprints, but there is also quite a bit of overhang on it as well.
Maybe an inch or two sure, but 6 inches? That is a little extreme IMO. And angle and camera lens plays a big role as well. In this shot it doesn't look too bad.
I think people need to just get over the whole Toyota using BMW's engine part. There are tons of very expensive cars out there that use engines from Mercedes, BMW, GM, and etc.
