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 Mustang GT Bi-Fuel CNG

Highly intrigued, we recently visited a Southern California Gas Company office to check out several hybrid vehicles promising something new. Unlike more commonplace gasoline-electric hybrids, we were there to evaluate innovative gasoline-compressed natural gas (CNG) hybrids - yes, they run on unleaded gasoline and compressed natural gas. According to the experts on hand, this arrangement delivers extended range and reduced emissions while chipping in with lower operating costs than pure-gasoline vehicles. There are advantages over its gasoline-electric counterparts, as well.
The program is part of a three-way collaboration between The Carlab, a Southern California-based automotive consulting firm, Landi Renzo USA, a company specializing in alternative fuel solutions, and America's Natural Gas Alliance, a group that promotes CNG. Long story short, the team has engineered a way to allow a modified internal combustion vehicle to seamlessly switch between two fuels (gasoline and CNG) with no driver intervention. In theory, and if it works as well as promised, it's a win-win for the vehicle owner and the environment.
Parked at the Gas Company office were six different gasoline-CNG hybrid vehicles. To demonstrate the technology's versatility (just about any gasoline vehicle may be modified) Carlab brought a varied assortment of bodystyles, each from a different automaker. After taking a quick glance at the half-dozen in the parking lot, we made a beeline for the performance-oriented Ford Mustang GT - a 2012 model - with the six-speed manual gearbox.

Toyota, Ford decide to end hybrid collaboration before it starts

Not all so-called Memorandum of Understanding pacts end in actual collaborations. For instance, after a two-year "feasibility study," Toyota and Ford have just announced that they will not be developing hybrid systems for use in light trucks and SUVs as previously planned, and the two automakers will instead continue to develop their own hybrid technology independently.
The would-be collaboration was first announced in August of 2011, and would have seen a rear-wheel-drive hybrid platform that would "improve the efficiency of trucks and SUVs while still allowing them to be driven in the way customers expect," according to our initial post on the topic.
Keep in mind that this announcement isn't to say we shouldn't expect hybrid pickups and SUVs from the two automakers, but that they probably aren't coming very soon - Ford says it will have a system "before the end of this decade" and we haven't heard much from Toyota on the hybrid truck front since the 2008 A-BAT Concept (pictured above) - and that they will not share any components between them (and they never have, for what it's worth).
