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 recalls over 500,000 trucks and SUVs, including Explorer, F-150, and Lincoln Aviator

For the second time in a month, Ford is recalling the brand-new 2020 Explorer and 2020 Lincoln Aviator for minor safety issues. This recall, which also affects certain 2018-2020 Ford F-150s, 2019-2020 Ford F-Series Super Duty trucks, 2018-2019 Ford Explorers, and 2019-2020 Ford Expeditions, pertains to potentially faulty seat-back reclining mechanisms. In total, the recall touches 550,186 vehicles. A mechanical part meant for relaxation and comfort has the Ford Motor Company stressin'. Ford says potentially affected vehicles might be missing the "third pawl required for seat-back strength" in the reclining mechanisms on certain seats. Because of this, the seats might not properly keep a person in place during the event of a crash or otherwise.  In the F-150s, F-Series Super Duty trucks, 2018-2019 Explorers, and Expeditions, the recall affects vehicles with manual driver and/or front passenger seat-back recliners. On the 2020 Explorers and Lincoln Aviators, rear outboard seats with manual recliners are of concern. Of the more than 550,000 vehicles, 483,325 vehicles are in the United States, 58,712 are in Canada and 8,149 are in Mexico. Thus far, Ford is not aware of any injuries from the issues. Ford says it expects most vehicles will not need repair, but dealers will inspect the seat structures out of precaution. If fault is found, dealers will replace the seat structure altogether. For this recall, Ford's reference number is 19C07. Contact your dealer for more information. Featured Gallery 2020 Ford Explorer View 47 Photos Recalls Ford Lincoln Truck SUV

Ford GT gets sexy shape and EcoBoost power [w/videos]

American automakers make vehicles of all shapes and sizes, but the one thing they almost invariably share in common is their front-engine layout. Niche offerings from the likes of SSC, Saleen and Vector (and the almost anecdotal Pontiac Fiero) aside, the most notable exception has been the Ford GT. And now it's back. Launched on the floor of the 2015 Detroit Auto Show, the new Ford GT picks up where the last one left off the better part of a decade ago – similarly taking its cues from the original, Le Mans-winning GT40, but in a less retro, more modern form. Instead of the atmospheric V8 in the original or the supercharged one in the retro revival, the new GT packs a 3.5-liter twin-turbo V6 nestled in the middle of its wheelbase and driving "more than 600 horsepower" to the rear wheels. Although Ford hasn't revealed the specific output or performance figures, it says the engine – derived from its Daytona Prototype unit and mated to a seven-speed DCT – is its most powerful production EcoBoost ever. Fortunately it's got carbon-ceramic brakes to keep it all in check, packed into 20-inch wheels wearing Michelin Pilot Super Sport Cup 2 rubber. The discs aren't all that's made from carbon on the new Ford GT, though: it's built around a carbon monocoque with structural carbon-fiber body panels, but with aluminum sub-frames front and back. Ford designed the new GT with a narrower canopy than its predecessors, cutting the frontal aerodynamic profile and tapering towards the back. It's also equipped with active aero elements including an active rear wing. Upwards swinging doors ought to make ingress and egress easier to and from the cockpit that's fitted with fixed seats, adjustable pedals and F1-style steering wheel and a fully digital instrument cluster. The new GT is set to enter production next year to celebrate the 50th anniversary of the GT40's famous 1-2-3 finish at the 1966 running of the 24 Hours of Le Mans. By the time it does, we're sure Ford will let us know just how fast America's newest supercar will be.
