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.

Ford Explorer gets appearance pack for 2015

Remember when Ford launched the totally new Explorer in late 2010, and people were skeptical about how the now-crossover would fare, after ditching its traditional SUV roots? Well, we're several years in, and I think we can assuredly say that Ford made the right decision. Sales are better than ever (in fact, May was the current Explorer's best month yet), and the crossover is finding its way into the hands of a whole host of new Ford buyers.
A wholly refreshed Explorer is still forthcoming, but to keep its strong-selling crossover fresh, Ford is offering a host of improvements for the 2015 model year, including the attractive appearance package available on the XLT trim level, pictured above. Outside, the pack gets you goodies like 20-inch machined aluminum wheels, black bodyside cladding and roof rack rails. Contrasting Magnetic Metallic accents are found on the grille, mirror caps and liftgate appliqué, and there's an "Explorer" hood badge and body-colored door handles. Inside, there are new Miko suede inserts in the seats, and the package includes the automaker's Sync connectivity with MyFord Touch infotainment.
Elsewhere in the Explorer range, the Class III trailer tow pack is now standard on the Sport, base models get new 18-inch aluminum wheels, and there are three new colors on offer: Bronze Fire Metallic and Magnetic Metallic.

Ford auctioning off F-35-themed 2015 Mustang for charity

Ford's been a supporter of EAA AirVenture, a huge, annual air show held in Oshkosh, WI, for several years now, with one of its most notable contributions being a modified Ford Mustang, designed to look like one of America's great fighting aircraft. There was an SR-71 Mustang, based on the legendary spy plane, a Red Tails edition, which honored the ground-breaking Tuskegee Airmen of World War II, as well as Blue Angels and Thunderbird Mustangs, based on America's two great military aerial demonstration teams.
Each car is auctioned off, with all proceeds going to the EAA Young Eagles program, which introduces kids to the joy of flight. For the 2014 AirVenture, which runs from July 28 to August 3, the one-off pony car is based on the new-for-2015 Mustang, and America's latest fighting aircraft - the controversial F-35 Lightning II.
The unique Mustang sports titanium paint scheme, with both glossy and matte sections, as well as yellow-and-blue trim and decal elements inspired by CF-1, the first F-35 test plane. A carbon-fiber front splitter and rear diffuser add some visual eye candy, while the interior boasts a set of Recaro seats. Ford also opted to fit unique wheels and a brawnier rear spoiler, to tie everything together.
