the 2000 nissan skyline, in bone stock form with an inline 6 cylinder, makes almost as much horsepower to all four wheels as the mustang does with a V8...4.6L compared to a 2.6L...

the evolution 9 makes almost 300hp with a 2.0L...the new mustang GT also makes 300hp, with a 4.6L...

its not the japanese automakers fault that the american v8s are inefficient...
