The 3/4 ton+ segments are not subject to fuel economy regulations.Has Toyota proclaimed they can't make a fuel efficient V8.
Did they try a 10 spd trans on one and engine revisions? Ford can make a 7.3 somewhat efficient on a much larger 3/4-1 ton truck...
The big three have all done so.
Thoughts?
If you notice, none of the domestics have built "all-new" V8 platforms in recent years. The R&D for the Coyote was probably done over 10 years ago.
