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.

Feds looking into Ford Explorer exhaust leak complaints

There may be a burgeoning problem with exhaust leaks in the 2011-2014 model year Ford Explorer. The National Highway Traffic Safety Administration is examining multiple complaints of a gasoline smell in the cabin of these SUVs. However, the exact cause of this problem is still unknown.
"The agency is reviewing all available data and will take appropriate action as warranted," said a NHTSA spokesperson in an email to Automotive News. Owners seem to generally complain on the regulator's website of the smell entering the cabin through the air vents. At this time, the government organization has not yet opened an official investigation into the problem, though. When it does begin inspecting vehicles, NHTSA posts a detailed breakdown of its public data online.
Similar problems have been reported about the Explorer in the past, though. In 2013, Ford issued a recall for the 2013 model year of the SUV due to a fuel leak that could cause drivers to smell a gasoline odor and repaired them again later for another possible leak. In response to Autoblog's questions, Ford responded via email: "We are not aware of a NHTSA investigation. We are currently reviewing the case and in the event that any action is required, we will address it promptly."

Ford files patent for 11-speed transmission

The automatic transmission seemed limited to three or four gears for decades, and then the automotive world slowly started to see more ratios becoming available. Today, seven-, eight- or nine-speed gearboxes have become rather common. Ford even has an automatic with 10 gears on the way for the future F-150 Raptor. The Blue Oval might not be done yet, though, because the company also now has a patent on an 11-speed box. The filing, which was discovered by AutoGuide, says this idea "produces eleven forward speed ratios and one reverse speed ratio by selective engagement of three shift elements in various combinations," and the company outlines three different ways of making this possible. The advantage of adding one more ratio is that the gearbox should be able to keep the revs in the ideal portion of the engine's torque curve even longer. Obviously, automakers patent ideas constantly, and applying for one is no guarantee that the tech ever arrives on the market. Conversely, these documents provide a tiny glimpse at one of the brand's focuses of development. If you're mechanically minded or just curious, you can read the entire application here for the technical nitty-gritty.
