...a "back-to-the-original-point" summary: Gasoline Direct Injection (GDI) has been around since the 1940's...that's over 70 years...and it's only "recently" (and under the new threatened EPA 56 mpg CAFE) that Detroit has seen fit to start using it.
...and, THAT is simply another example of Detroits' "feet dragging", ie: never do MORE than the Government (or Common Sense) absolutely requires!
