Ford C-Max sales hold steady despite fuel economy fracas

Despite the ballyhoo that accompanied Ford's lowering of the C-Max fuel economy figures, the Blue Oval is still seeing strong demand for the five-seat MPV, as Automotive News reports. Speaking to marketing boss Jim Farley, AN says that the controversy surrounding the C-Max's fuel economy figures won't force Ford to change its marketing strategy.
Ford lowered the fuel economy rating of the C-Max after public outcry and legal action by customers that were unable to reach the 47 miles per gallon promised by the window sticker. The new ratings were dropped about a month ago to 45 mpg on the freeway and 40 mpg in the city. Ford offered rebates for current C-Max owners, with $550 going to those that bought their car and $325 to lessees. The issue, says Ford, stemmed from testing standards that allowed the automaker to base the C-Max's fuel economy on the Fusion Hybrid, because they use identical powertrains. The C-Max's less aerodynamic shape wasn't taken into account, though.
Whether Ford's PR team handled the crises perfectly or people just aren't that bothered by a four-mpg drop in combined ratings, demand remains strong for the C-Max among consumers. Ford moved 3,000 units in August, which was a 12-percent jump over July sales. Meanwhile, consumer demand through third-party shopping websites remains strong as well, according to Autometrics, a data analysis company that spoke with Automotive News. While the long-term effects of the adjustments remain unknown, the C-Max appears to have fared well in the near term.

NHTSA opens investigation into Ford Explorer PI brakes

This year more than most, it's pleasant when we can string together a few days without word of an automaker or the National Highway Traffic Safety Administration announcing a bunch of new recalls. It's seemingly been a little quiet on this front lately (barring a spider-related Suzuki issue revealed early today), but now we have word of the government safety agency opening a Preliminary Evaluation into the 2013 Ford Explorer Police Interceptor, a probe that could potentially affect an estimated 20,000 vehicles.
The issue being investigated concerns failures of the front brake hose on the vehicle that show "small splits in the hoses near the body side ferrule of the hose assembly," according to the agency, and the issue could result in longer stopping distances. The feds have reports of 13 malfunctions affecting 11 Explorer units. However, it's important to note that all of the incidents come from a single, unnamed metropolitan police fleet that operates 46 of them. According to The Detroit News, the failures generally took place between December and July.
NHTSA is investigating further to find if this is a more widespread issue than just this one fleet. Ford spokesperson Kelli Felker confirmed to us, "We are cooperating with NHTSA on this investigation, as we always do." Scroll down to read the agency's report.

Ford finds flex-fuel engine design plays big role in emissions output

How bad is ethanol for your engine? There's been a lot of debate on this issue as the US considers upping the biofuel content in the national gasoline supply from 10 percent (E10) to 15 percent (E15). The ethanol industry and some scientists say higher ethanol blends show no "meaningful differences" in new engines while the oil industry says ethanol creates health risks. Researchers working at the Ford Research and Innovation Center decided to take a closer look at how a wide range of gas-ethanol blends - E0, E10, E20, E30, E40, E55 and E80 - affected the emissions coming out of a flex-fuel 2006 Mercury Grand Marquis. To see the full report, printed in the journal Environmental Science & Technology, requires payment, but there is an abstract and Green Car Congress has some more details. The gist is that, "with increasing ethanol content in the fuel, the tailpipe emissions of ethanol, acetaldehyde, formaldehyde, methane, and ammonia increased." At least NOx and NMHC emissions decreased. The researchers say that the effects are due to the fuel and "are expected for all FFVs," but that the way that a manufacturer calibrates the engine will affect NOx, THC, and NMOG emissions. It's this last bit that's important, since the researchers found, "Higher ethanol content in gasoline affects several fundamental fuel properties that can impact emissions. ... These changes can have positive or negative effects that can depend on engine design, hardware, and control strategy. In addition to direct emissions impacts, higher ethanol content fuel can also provide more efficient combustion and overall engine operation under part-load conditions and under knock-limited higher-load conditions." So, as we head towards more ethanol in our fuel supply (maybe), manufacturers are going to need to learn how to burn it most efficiently.
