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.

Automakers' rush on aluminum may result in shortage

Aluminum is the new buzzword in the automotive industry. The latest Range Rover and Range Rover Sport both take advantage of the lightweight material to shave huge amounts of body fat (only it's called "aluminium" over there). Audi and Jaguar have been using the stuff for years in their A8 and XJ, respectively, and now, aluminum is going mainstream, arriving on the 2015 Ford F-150.
While we're excited to see aluminum make an impact outside the premium market, its widespread adoption apparently won't come without some problems, notably in terms of supply. "There isn't an automotive manufacturer that makes vehicles in North America that we're not talking to," Tom Boney, of Novelis, the largest global supplier of aluminum sheetmetal, told The Detroit News.
According to Boney, Ford's use of aluminum on such a large scale has forced auto manufacturers in "every boardroom" to reconsider their plans following the F-150's unveiling, for one simple reason: there's not exactly enough aluminum to go around, at least in the short term. The auto industry presently only accounts for six percent of the aluminum sheet produced, but as the material is adopted by more and more brands, that figure is expected to swell to 25 percent within the next six years.

Ford open to diesel, hybrid or electric Mustang? [w/poll]

The Ford Mustang may not be the first vehicle that comes to mind when you think of environmentally-friendly forms of transportation. The arrival of the turbocharged four-cylinder engine in the new Mustang could do a lot to combat that perception, but the EcoBoost engine may just be the tip of the iceberg in that regard.
Speaking with Ford powertrain boss Bob Fascetti at the reveal of the new Mustang in Australia, GoAuto reports that the Blue Oval automaker is considering offering its latest pony car with a diesel, hybrid or even electric powertrain in the future.
"We're not looking at diesel at the moment, but given where we need to go with fuel consumption we are looking at all our options," said Fascetti. Other options could include a nine- or ten-speed automatic transmission to replace the current six-speed unit in order to help improve fuel economy and emissions for the Mustang, although figures for the current lineup have yet to be revealed.
