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.

Expert: 54.5 mpg CAFE standard can be reached without many plug-ins

Johnson Controls executive Brian Kesseler isn't likely to get any holiday presents this year from Nissan chief Carlos Ghosn or Tesla Motors head Elon Musk, but lots of other folks might be happy with what he has to say about automakers' efforts to reach stricter fleetwide fuel-economy standards. Speaking at the Automotive News World Congress, Kesseler said automakers wouldn't need to sell an extensive number of plug-in vehicles in order to meet the 54.5 mile per gallon Corporate Average Fuel Economy (CAFE) standard the US government set in 2012 for 2025 model-year vehicles. In fact, he said, components such as stop-start engine technology, turbochargers and direct injection may actually do the trick. Already, things like smaller engine sizes and lighter cars are already playing major roles in spurring fuel-efficiency gains. Of course, Johnson Controls sells batteries specially built for stop-start systems, so Kesseler does have a bit of skin in this game. The 54.5-mpg CAFE standard equates to about a 40-mpg "real world" fuel-efficiency level. To put that into perspective, the Environmental Protection Agency (EPA) said in a report late last year that model-year 2013 average fuel economy was an even 24 mpg. That was up from 23.6 mpg for the 2012 model year and 22.4 mpg for 2011.

Diesel Power finds the ultimate modified oil-burner

For nine years, Diesel Power magazine has run the Diesel Power Challenge, this year's grindfest being "a week-long torture test that features seven events, nine trucks, 8,000 horsepower, and nearly 15,000 pound-feet of torque." The road to being crowned "the most powerful truck" starts with a dyno run, and then continues through the completion of a CDL-style obstacle course, an eighth-of-a-mile drag race while towing a 10,000-pound trailer, a quarter-mile drag race without a trailer, a fuel economy test in the mountains and finally a sled-pulling test through a 300-foot-long packed-mud pit.
What kind of trucks get into such a fight? Last year's winner, for instance - who upgraded his truck this year to prove he didn't "luck into the win" - drives a 2008 Ford F-250 Super Duty with a 6.4-liter Power Stroke V8 upgraded with a custom intake, Elite Diesel triple turbos and a two-stage nitrous system. Another competitor has a 2005 Dodge Ram 2500 powered by a 5.9-liter Cummins inline-six, upgraded with Garrett turbos, dual-stage nitrous, a seven-inch exhaust stack and twin fans built into the bed to cool the Sun Coast Omega transmission. The numbers on that truck: 1,255 horsepower, and 2,063 pound-feet of torque at the wheels. Naturally, as the image above might suggest, things don't always end well.
You'll find all five videos covering this years challenge below. A scene in the dyno video sums it all up perfectly: a competitor leaves his nitrous on too long and the crew is treated to some ominous poppings, he leans out the window, throws both hands up and shouts, "Amer'ca!"
