Happy Mustang Day. Are you tired of hearing about the 2015 Ford Mustang yet? No? Good, here's a bunch of mechanical data on Ford's sixth-gen muscle car, along with cutaways of the GT's 5.0-liter V8 and the new 2.3-liter, EcoBoost four-cylinder shown above. We also have a smattering of info on the Stang's updated transmissions and an exploded-parts-diagram view of its all-new independent rear suspension.
