Ford introduced its 2015 F-Series Super Duty lineup at the Texas State Fair and the big news is a better Power Stroke V8 turbo diesel engine. They've also beefed up the F-450 to make it even tougher. The new Power Stroke features a larger GT37 turbocharger that measures 72.5 millimeters in diameter versus the smaller GT32 it replaces which came in at 64 millimeters. This means exhaust gases have a larger surface area to spin the turbo so you'll get extra power.
