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.

Feds open investigation into Chevy Express, Ford Freestar rust issues

'Tis the season... for road salt. And with that, comes rust. And what does rust bring? Well, for Ford and General Motors, a National Highway Traffic Safety Administration investigation. According to The Detroit News, NHTSA is looking into potential recalls issues with Chevrolet Express vans and Ford Freestar minivans.
The feds have received five complaints that rust has caused leaking fuel filler pipes on 2003 Express vans. Separately, seven complaints have been filed over excessive rust in the rear wheel wells of 2004 Ford Freestar and Mercury Monterey minivans. The Freestar and Monterey went out of production in 2007. Neither issue has resulted in any crashes or injuries, according to the report.

Ford Focus refresh shots leak ahead of Geneva

In case you haven't been paying attention, Ford has been gradually redesigning its lineup to sport a familiar face. The Aston Martin-inspired grille shape debuted on the Fusion and was soon applied to the Fiesta. Even the front end of the new Mustang takes its cues from the same, and we're sure other models will soon be made-over to fall in line. The next on the docket? The Focus.
Set to be unveiled in little over a week at the Geneva Motor Show, the revised Focus has leaked out a tad early, revealing a mild facelift that bears that same trapezoidal grille with horizontal slats. Along with the new grille, the headlights, lower fascia and hood appear to have been reshaped. Around back there appears to be a new rear bumper and taillights, but otherwise the shape remains largely the same as the current model.
Expect the updates to be applied to all bodystyles offered around the world, including the hatchback, wagon and sedan. The engine lineup is expected to carry over largely unchanged, though the plug-in hybrid powertrain from the C-Max Energi could port over to the revised Focus. Plus Ford seems to have taken the opportunity to spruce things up in the cabin some. Check it out in the image gallery above and watch this space for the official announcement as we pack our bags for Switzerland.
