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.

The fascinating forgotten civil defense history of Mister Softee trucks

Hemmings came across an interesting article from the Throwin' Wrenches blog about the intersection of ice cream, cars and civic duty in America's late 1950s. In particular, it focuses on the Mister Softee trucks, which criss-crossed neighborhoods of the eastern US serving ice cream. Looking past the ultra-durable vehicles used - heavy-duty Ford-based chassis, for what it's worth - the article delves into some deeper national-security territory.
See, Mister Softee truck owners were voluntary members of the Civil Defense, thanks to all the useful stuff (potable water, generators, freezers and fridges) that the machines carried with them for serving ice cream. Click over to Throwin' Wrenches for the full run down of how Mister Softee would have stepped in to help fight if the Cold War ever turned a little hotter.

Detroit Three to lose dominance of North American auto output in 2017

DETROIT — North American vehicle production by the unionized Detroit Three automakers will fall behind the combined North American output of Tesla and automakers from Europe and Asia for the first time this year, IHS Markit forecast on Wednesday. In 2017, the Detroit Three could build 8.6 million vehicles in North America, while Tesla and foreign automakers build 8.7 million, IHS Markit analyst Joe Langley said. By 2024, the gap will widen, with Asian and European automakers and Tesla combining to build about 9.8 million vehicles in North America. General Motors, Ford and the North American operations of Fiat Chrysler Automobiles NV will combine to build 8.1 million vehicles, down 6 percent from this year. Mexico is on track to increase its share of North American vehicle production, Langley said, moving to 4.5 million vehicles a year by 2024 from about 4 million vehicles currently. The milestone for the growth of Tesla and foreign automakers in North America comes as the Trump administration is pushing to limit imports of vehicles from Mexico in negotiations to overhaul the North American Free Trade Agreement. The declining share of North American vehicle production for the Detroit automakers also challenges U.S. and Canadian unions that represent their workers. Canadian workers are on strike at a GM factory in Ontario to protest the automaker's decision to cut jobs and move to Mexico some production of sport utility models built there. Foreign automakers over the past year have announced plans for a wave of new or expanded plants in North America, while Tesla is ramping up to build as many as 500,000 cars a year at its plant in Fremont, Calif. Often referred to as "transplants," the foreign-owned factories are poised to become the mainstream of the North American auto industry. Automakers are increasingly using factories in China or Mexico to build vehicles that used to be assembled solely in the United States, Langley said. He cited as an example Ford's decision to shift production of the Focus small car for North America to a Chinese assembly plant.
