Ford updates Power Stroke diesel V8, strengthens F-450, tweaks King Ranch

Ford is giving its F-Series Super Duty trucks some upgrades for 2015, and we're happy to say that one of them is an improved Power Stroke diesel V8. Also, Ford is strengthening the top-of-the-line F-450 to handle more abuse. And if wild west-style luxury is your thing, the automaker has performed minor cosmetic updates to its King Ranch Edition trucks, as well.
The turbocharged 6.7-liter Power Stroke V8 is currently rated at 400 horsepower and 800 pound-feet of torque, and Ford only tells us the new and improved Power Stroke can "produce power beyond today's" engine. What, then, did Ford actually improve upon? First, the Blue Oval swapped in a new, larger turbocharger. The new Garrett GT37 turbine unit is 72.5 millimeters in diameter, eclipsing the old GT32's 64-mm diameter piece. Ford states output increases with the new turbo setup, but since the new turbocharger operates at a lower peak pressure than the old one, the automaker was able to eliminate the wastegate system and reduce the engine's complexity. Ford even redesigned the turbo's oil and cooling lines to make the powerplant simpler. A byproduct of the larger turbo is better engine exhaust braking, which is controlled manually by a button on the dashboard.
Ford claims the upgraded diesel engine is more powerful, more robust, more efficient and more refined than before.

2015 Ford Mustang EcoBoost

Earlier this week, Ford invited us to Charlotte, NC, to ride in an all-new 2015 Mustang fitted with its turbocharged 2.3-liter EcoBoost four-cylinder. It's the first forced-induction, four-cylinder ponycar for the Blue Oval since the sun set on the 1986 Mustang SVO. We jumped at the opportunity, as only a handful of people have ever been in the passenger seat of this new car, and most automotive media won't get as close as we did until this fall.
As we revealed in our Deep Dive, Ford will slot this new turbocharged four as premium powerplant between its naturally aspirated 3.7-liter V6 and the naturally aspirated 5.0-liter V8. At last mention, the automaker said the direct-injected, all-aluminum engine will develop 305 horsepower and 300 pound-feet of torque, returning the best fuel economy of the three powerplants in the process. History buffs will note that those figures are appreciably stouter than the 200 horses and 240 lb-ft that the '86 SVO realized out of the same displacement, and the latter's figures were hugely impressive at the time. On paper, the new EcoBoost four looks to be a good fit for most owners who want to balance performance with efficiency - we were eager to see how it felt from the passenger seat.

Spy shooter claims proof of upcoming aluminum Ford F-Series Super Duty

Ford has already confirmed that the 2015 F-150 (pictured above) was just the beginning for its more extensive use of aluminum. CEO Alan Mulally said it himself during the 2014 Detroit Auto Show. We've even already seen the future Raptor testing with an aluminum body. But a recent discovery from an intrepid spy photographer might indicate that the lightweight metal is coming to the Blue Oval's Super Duty pickups in their upcoming generation, as well.
According to Automotive News, a spy shooter in Colorado spotted a prototype for the next-gen F-350 testing. He happened to have a magnet on hand and got close enough to check the truck out. When he held it up to the metal in the bed, it didn't stick, which signaled to him a switch from steel to aluminum.
Obviously, this claim raises some questions. Given that it was a test vehicle, one possibility is that the Blue Oval is just evaluating the feasibility of switching to aluminum for the Super Duty trucks, not necessarily committed to it yet. Ford has been testing it quite exhaustively, after all. In fact, much of the rest of the truck in question was covered in camouflage, so it's possible that the magnet failed to work along the rest of the body not because it was aluminum, but because it wasn't powerful enough to get through the disguising material. Thus, the lightweight metal's use could be far less substantial than on the new F-150. Still, it was a clever idea for the cameraman to check things out and might have given us the first hint about brand's next heavy-duty models.
