Domestic companys aren't that far behind. Over head cam motors aren't new. And VVT technology was used on airplanes in WWII. Also, Ford had the first patent on VVT back in 76-77, and Toyota one year later. Honda was only the first company to use it in a production vehicle, NSX.

If I remember correctly, the CRX Si was the first Honda to get fuel injection back in the late 80s. Chevrolet had fuel injected Corvettes since the 60s.

If you can remember an old motor called the Chrysler Slant-6 [6 cylinder] from the 60s and 70s, it got 35mpg back in the 70s.

A lot of the "technology" used in a lot of Japanese imports were originally American or European designs. They just took the research farther and refined it.

Sure, OHC motors are great for gas milage. But ANY motor will be reliable if you TAKE CARE of it. I bet if you took a B16 motor and never changed the oil, never changed the transmission fluid, never changed the air filter, and just let the motor go with no maintance, it would die just like everyother motor out there. Well except the Slant-6, that motor can take anything you dish out on it [it's known as the only Indestructable motor ever made].

As Carrol Shelby said: Cheap, Light, Durable. Pick two because you can't have all three.
