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.

Ford turns Navistar from truck business customer to rival

There is a showdown brewing in the medium-duty truck segment next year as Ford prepares to launch its all-new, in-house engineered 2016 F-650 and F-750. It finally marks the end of the Blue Diamond joint venture between Ford and Navistar and, making the two entities direct competitors instead of partners.
Ford announced the end of the joint venture in an investor report in 2011, but it didn't reveal the new F-650 and F-750 until the NTEA Work Truck Show in Indianapolis, IN, in March. Unlike the current, Mexican-built models, the new generation will be built in Avon Lake, OH, starting in mid-2015.
The challenge from Ford comes during a rough patch for Navistar. The company had a $248 million loss in the first quarter, according to The Wall Street Journal, and its medium-duty truck market share is currently down to 26 percent, from 36 percent in 2011. Building the previous-generation Fords brought in about $400 million a year to Navistar, according to the WSJ. To take on its former partner, Navistar plans to offer its International brand of medium-duty vehicles with more engine and transmission options to customers. It even struck a deal with Cummins to put its diesels in some of the models.

Tier 1 suppliers call GM the worst OEM to work with

Among automakers with a big US presence, General Motors is the worst to work for, according to a new survey from Tier 1 automotive suppliers, conducted by Planning Perspectives, Inc.
The Detroit-based manufacturer, which has been under fire following the ignition switch recall and its accompanying scandal, finished behind six other automakers with big US manufacturing operations. Suppliers had issues with trust and communications, as well as intellectual property protection. GM was also the least likely to allow suppliers to raise their prices in the face of unexpected increases in material cost, all of which contributed to 55 percent of suppliers saying their relationship with GM was "poor to very poor."
GM's cross-town competitors didn't fare much better. Chrysler finished in fifth place, ahead of GM and behind Dearborn-based Ford, which was passed for third place this year by Nissan. Toyota took the top marks, while Honda captured second place.
