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 F-450 claims best-in-class towing, company abandons practice of removing items to boost payload number

The ongoing heavy-duty truck battle between Ford and Ram is showing no signs of slowing down. The Blue Oval is trying to remove at least one point of contention between the two brands by testing its 2015 F-450 Super Duty using the Society of Automotive Engineers J2807 towing standard, which Ram also uses. In the new evaluation, the F-450 is rated at a max towing capacity of 31,200 pounds. That's an identical amount as under Ford's own, previous test.
"We leave no doubt with customers that the F-450 pickup truck has best-in-class towing of 31,200 pounds - whether tested using our own internal towing standards or SAE J2807," said Raj Nair, Ford group vice president for Global Product Development, in the company's release.
At the same time, Ford is also changing how it calculates the F-450's payload. Instead of using its minimum curb weight as before, the brand is now using the truck's base curb weight. The revision lowers the pickup's rating to 5,300 pounds, compared to 5,450 pounds previously. The company said in its announcement that the reason for this is "aligning its payload rating practices with other manufacturers to make it easier for customers to compare vehicles." General Motors made a similar switch for its pickups in August.

Will the new Ford GT race at Le Mans?

Ford stole the spotlight here on the floor of the Detroit Auto Show this year with the reveal of the new GT. Its carbon-fiber chassis, 600-plus-horsepower EcoBoost engine and radical aerodynamic shape made sure of that, but flanking it with the debuts of the Mustang GT350R and F-150 Raptor didn't hurt any, either. Any racing fan looking at the new Blue Oval supercar, however, had to wonder whether Dearborn is planning on putting it on the race track. The House that Hank Built is, after all, a known entity in motor racing. It may be canceling its V8 Supercars program Down Under, withdrawn its support from the World Rally Championship, and it's been years since it's competed in Formula One or Indy. But it still competes in the United SportsCar Championship, NASCAR, NHRA and a variety of motor racing disciplines. One of its most famous and celebrated of racing endeavors, however, came in the form of the original GT40 that brought Ford four consecutive victories at the 24 Hours of Le Mans, starting with a dominant one-two-three finish in 1966. It's the 50th anniversary of that landmark win which the new Ford GT celebrates, but while the press materials made clear reference to that historical event, any mention of a return as was previously speculated was carefully omitted. That, according to Autosport, could come down purely to the ACO, the organizers of the event and sanctioning body for its associated series, which has yet to announce the revised format for the GTE class under which a potential Ford GT racer would compete in 2016. Longtime Ford racing partner Multimatic is said to have closely consulted with the ACO on the formation of those rules, however, and assuming they're finally formulated to Dearborn's liking, we could be looking at a GTE-spec Ford GT to return to La Sarthe next year in celebration of that landmark victory half a century prior. Chip Ganassi Racing – which races under Chevy power in NASCAR and Indy but recently switched to Ford for its Daytona Prototype – is said to be in line to field the car on Dearborn's behalf. If given the green light, it would be the first time Ford would field a factory effort at Le Mans since the C100 project under the Group C category in the early 1980s. A racing version of the previous Ford GT was prepared by Switzerland-based Matech a few years ago, but without factory support or notable success beyond the FIA GT3 European Championship.
