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.

Report: GM struggling to market turbo technology

In the automotive realm, marketing can sometimes prove just as important as the actual product. Take, for instance, Ford's well regarded EcoBoost technology, which couples turbocharging with direct injection to produce more horsepower and reduce fuel consumption. Would it surprise you to hear that General Motors has had similar technology on the market for over three years?
It's true. GM's first turbocharged, direct injected powerplants hit the market for the 2007 model. The 2.0-liter Ecotec mills put down an impressive 260 horsepower and a matching 260 pound-feet of torque, and they were lauded by the press in the engine bays of the Pontiac Solstice, Saturn Sky, Chevrolet Cobalt SS and Chevrolet HHR SS. But few people outside a core group of enthusiasts actually remember this fact.
Says Uwe Grebe, executive director of GM's global advanced engineering, "We didn't have a badge and say, 'This is the most important thing we will put on all our brochures.'" Ford, however, did just that, and it's EcoBoost engines are right at the tips of all our tongues when we discuss today's most advanced powerplants. So, how does The General fix its mistake?

Ford going bonkers at SEMA with 57 showcars

Ford always shows up in force at the SEMA Show, but this year's tally of 57 custom-tuned cars, trucks and vans is more than we can ever recall the Blue Oval bringing. Ford will introduce 28 of its project vehicles in its "Dreamcase" ahead of next month's show. The first batch of eight you'll find here with the remaining vehicles trickling into public view over the next couple of weeks.
This first group of cars includes a Fiesta, four Fiesta ST hatchbacks and a trio of Mustang show cars styled and tuned to varying degrees all by different aftermarket companies. Tanner Foust, Nitto Tire, 3dCarbon and Ice Nine Group are some of the more familiar names affixed to these cars. Our favorite so far is the Hollywood Hot Rods Mustang convertible (shown above) with its removable aluminum top and methanol-injected, 750-horsepower 5.0-liter V8.
Scroll down for all the details on these Fiestas and Mustangs, and stay tuned for more info on Ford's SEMA line, which will include custom versions of the Focus ST, Fusion, Transit Connect, F-150 and Super Duty.
