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.

2015 Ford F-Series Super Duty Power Stroke

What weighs 30,000 pounds? Big Ben's Westminster bell. A navy ship anchor. Or as we found out during our first drive program for the 2015 Ford F-Series Super Duty, seven pallets of cinder blocks loaded onto a dual-axle gooseneck trailer. The test was part of a raft of towing demonstrations that showcased the new Super Duty's impressive tug capacity, which maxes out at 32,100 pounds. That's 1,200 more than its nearest rival, the Ram 3500, when equipped with its upgraded 6.7-liter Power Stroke diesel V8. Such is the heavy-duty pickup truck business, a diesel-fueled game of one-upmanship with only three players: Ford, Chevrolet/GMC and Ram. And in this game, the one with the most torque wins.
Until 2014, Ford was the one to beat, with its 6.7-liter Power Stroke diesel bringing 400 hp and a massive 800 lb-ft of torque to the table. Then last year, Ram did exactly that, serving Ford with a beefed-up Cummins turbodiesel inline-six in its freshened Ram Heavy Duty truck line with 385 hp and 850 lb-ft of torque, enabling it to tow up to 30,000 pounds. But Ford claims it had designed its engine to be relatively easy to upgrade when the time called for it, so for 2015, Ford bolted a larger turbo to the Power Stroke, bringing output to an insane 440 hp and 860 lb-ft of twist, all without reducing fuel efficiency. Maximum tow capacity rises from 24,700 lbs to an incredible 31,200 lbs for the F-450 dually.
As for GM's HDs? They lag behind the lot with their 6.6-liter Duramax V-8, producing 397 hp and 765 lb-ft of torque. Yeah, you know things are serious when the trucks with 765 lb-ft are the knock-kneed wimps of the lot.

NHTSA closes book on Ford, GM probes of 600,000 vehicles

US safety regulators have closed a pair of investigations into some 500,000 Ford Crown Victoria, Mercury Grand Marquis and Marauder sedans built between 2004 to 2007, and 100,000 Chevrolet Impala models from 2014. The Ford investigation focused on rusting heat shields, which may become dislodged and jam the steering, according to Reuters. The National Highway Traffic Safety Administration found that this happened very rarely. In fact, of the ten incidents filed with the government safety watchdog, six came from a single police department, which evidently had some sort of problem with its reporting. As for the Impala, the NHTSA investigators attributed two incidences of "unintended autonomous braking" to user error. In both cases, the vehicles were involved in rear-end collisions. According to GM investigators, it's believed that drivers accidentally activated the electric parking brake, causing the collisions. The vehicles in question were rental cars.
