EPA says fuel economy test for hybrids is accurate

The EPA says it stands behind its fuel economy test for hybrid vehicles following controversy about the testing process after Ford C-Max Hybrid customers and automotive journalists alike struggled to achieve 47 miles per gallon, the advertised mpg number, Automotive News reports. Ford responded to the issue almost two weeks ago by claiming that a 1970s-era EPA general label rule was responsible for the inaccurate mileage numbers, rerating the C-Max Hybrid's mpg numbers and offering customers rebates. Ford later said it didn't overstate the C-Max Hybrid's fuel economy and that it was surprised by the low numbers.
Ford technically didn't do anything wrong because it was following the general label rule, but agency regulator Christopher Grundler says the automaker was exploiting a loophole when it came up with the hybrid C-Max numbers, and that the testing process remains accurate. The general label rule allows vehicles that use the same engine and transmission and are in the same weight class to share fuel economy numbers, but it doesn't take into account other factors such as aerodynamic efficiency, which affects hybrids more drastically than non-hybrid vehicles. Ford originally used the Fusion Hybrid economy figures for the C-Max Hybrid and claimed the engineers didn't realize that its aerodynamic efficiency would affect fuel economy as much as it did.

Shelby GT350R offers first mass-produced carbon fiber wheels

In the world of race engineering, reducing total weight is good, but reducing unsprung weight is flippin' fantastic. That's the reason Ford is pushing the envelope in terms of technology for the Shelby GT350R's wheels. Joining the likes of Koenigsegg in the offering, Ford has teamed with Australian outfit Carbon Revolution to produce the CF rollers en masse for the first time. Destined for the hubs of the new Shelby GT350R, the new hoops weigh just 18 pounds each, versus the 33-lbs weight of a similar aluminum wheel. On top of slashing up to 60 pounds in unsprung weight, there's such a reduction in rotational inertia – 40 percent, versus aluminum wheels – that Ford actually has to recalibrate the magnetic ride control system and springs. Thanks to, we're guessing, scenes of crashed Formula One cars disintegrating and spewing shards of carbon fiber all over the track, Ford seems quite keen to do away with the idea that CF is strong, but brittle. The company conducted extensive shock testing, ramming a wheel into a curb at speed. According to the Blue Oval, the lightweight wheel allowed the suspension to respond so quickly that the impact was "greatly diminished," causing the tester to run the experiment again, thinking there'd been a mistake. After recording brake rotor temperatures of 900 degrees Celsius (over 1,650 degrees Fahrenheit, or well past the point that aluminum or magnesium would melt) during testing, Ford and Carbon Revolution actually redesigned the wheels to "a thermal standard more suitable for motorsports," by adding an "incredibly thin, nearly diamond-hard coating that reliably shields the resin from heat." The same process was used to protect engine turbine blades on the Space Shuttle. While the work by Ford and Carbon Revolution should make GT350R customers excited, the work being done here could have serious implications for performance cars in the future. That's the real takeaway here, and is something that should leave fans of all performance vehicles excited.

Texas plumber shocked his old Ford F-250 is now in terrorists' hands [w/video]

Do you ever wonder what the a owner is doing with your vehicle after you trade it in? Mark Oberholtzer of Mark-1 Plumbing in Texas City, TX, has no need to imagine, but it's probably his worst nightmare. That's because an image of his old Ford F-250 is now on Twitter as a gun platform in the Syrian Civil War. While the image only appeared recently, Oberholtzer traded the truck in last November. Somehow since then the F-250 made its way from Texas to Syria. According to a report from television station WHOU, the dealer that took the trade said the pickup immediately went to auction. Unfortunately, along the whole route no one ever took Mark-1 Plumbing's name and phone number off the door. So when the image went up on Twitter, everyone knew whom the Ford previously belonged to. The plumbing company makes it abundantly clear that this whole bizarre situation is simply a coincidence, and it has absolutely no ties to the conflict in Syria. However, that isn't preventing people from phoning the business with angry calls and threats. Things are so bad that Oberholtzer keeps the phones unplugged for relief. Scroll down to watch a video of the guy's flabbergasted reaction to finding out what his F-250 is doing now. This content is hosted by a third party.
