Did a US automaker blow the whistle on Hyundai, Kia fuel economy issue?

In all of the most hotly contested mainstream segments of the motoring universe, the difference of one mile per gallon averaged on a widow sticker can mean the difference between a sale and a walk-off - to say nothing of two or three mpg. So, when Hyundai and Kia were forced to reveal that many of their 40-mpg ratings were actually 38s and 37s, well, it made for big news.
It also, conceivably, made for a competitive disadvantage immediately, when the Korean automakers' products were being shopped versus the guys down the block. And it's that disadvantage that makes a recent story from Automotive News so juicy.
AN is reporting that Margo Oge, former head of the Environmental Protection Agency's Office of Transportation and Air Quality, got a tip in 2010 that Hyundai/Kia were "cheating" to get its impressive fuel economy numbers. The tip, said Oge (who retired from the EPA this past September), came from a senior vice president from a domestic automaker. The source was credible enough for Oge to launch an audit of the Hyundai figures, which ultimately lead to the debacle that we reported on a few months ago, and that the Korean company has been trying to bounce back from ever since.

Ford Green Zone works magic with GPS to make your drive smarter, cleaner

For the most part, plug-in hybrids rely on the power stored in the battery until that charge is depleted. Unless the switch can be changed manually, it's only then that the cars fire up the internal combustion engine and begin using the fossil fuels on board. This is ideal, of course, when one's drive isn't long enough that the car needs to start sipping gasoline at all. On longer commutes, when it's certain that the route is longer than the car's all-electric range, this isn't necessarily the most efficient use of energy. Ford's Green Zone system is designed to save some of that juice for the parts of the drive that require slower speeds. Ford is working on a smart system, based on Nokia mapping technology, that uses GPS data to use both the electricity and conventional fuel more efficiently. Since battery power is less efficient at highway speeds, Ford's Green Zone system is designed to save some of that juice for the parts of the drive that require slower speeds, rather than just using up all the electrons right at the beginning of the drive. Using a website or the in-car navigation system, the driver can pinpoint the parts of the route, highlighted in green, where using battery power would be more effective, and set the car to automatically switch to electricity for those sections. Depending on the route, the car could automatically switch back and forth between the two power sources multiple times, particularly if the drive is a mix between city and highway driving. Of course, Green Zone will be go beyond that. The program is being developed to take traffic and road grade into account, details that allow the car to be make even smarter choices to improve efficiency. Ford even hopes to have Green Zone learn driver habits, and respond accordingly depending on who is driving the car. The system could control other features as well, such as anticipating corners and shifting the headlights to better illuminate the road ahead. Green Zone could also potentially use information from vehicle-to-vehicle networking to control functions in the car. The Green Zone system still has a few years before it will be ready to be put into production vehicles, but Ford is confident it will make its way onto the road eventually. As with other innovations that improve efficiency and make our vehicles smarter, we can expect to see similar technology from other manufacturers, until it becomes a regular part of driving in the future.

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.
