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.

Volkswagen Golf, Ford F-150 named 2015 North American Car and Truck/Utility of the Year

Congratulations, Volkswagen Golf/GTI and Ford F-150. You've just been named the 2015 North American Car and Truck/Utility of the Year, kicking off the first press day of the Detroit Auto Show. The Golf faced some seriously stiff competition from its runners-up, the Ford Mustang and Hyundai Genesis. But the Golf has been a highly awarded vehicle since its launch, including recently being named Motor Trend's Car of the Year. As for the Truck/Utility award, it wasn't immediately clear that the aluminum-bodied Ford F-150 would win the North American honor, topping the Chevrolet Colorado and Lincoln MKC. The Chevy, after all, has been widely praised since arriving this fall, including taking home MT's Truck of the Year award. In 2014, Chevrolet had a sweep of the NACTOY awards, with the Corvette Stingray and Silverado taking top honors. Here's a look at the 2015 North American Car and Truck/Utility of the Year voting breakdown. As you can see, it wasn't exactly neck and neck. Car of the Year Volkswagen Golf/GTI – 256 points Ford Mustang – 204 points Hyundai Genesis – 110 points Truck/Utility of the Year Ford F-150 – 297 points Chevrolet Colorado – 205 points Lincoln MKC – 68 points The winners were determined by the votes of 57 North American jurors who work in all forms of media – magazine, newspaper, television, online and radio, and their ballots were tabulated in secret by accounting firm Deloitte & Touche. Autoblog editors Sharon Carty and Chris Paukert are members of the North American Car and Truck/Utility of the Year jury.

Ford drops Focus RS teaser ahead of Feb 3 reveal

Ford is trying to get us hyped for the unveiling of the latest Focus RS on February 3 with this new video teaser. The clip showcases the hot hatch doing some big slides in the wet and dry during testing in Europe and the US, and it definitely makes us even more curious about what the Blue Oval has in store with the RS. Even in this short teaser, Ford continues to dress the more aggressive nose of the Focus RS in camouflage, like the previous test cars. Unfortunately, what's going on under all of that concealment remains a bit of a mystery. Rumors suggest the RS likely uses a tuned version of the Blue Oval's 2.3-liter turbocharged four-cylinder estimated to make between 325 and 350 horsepower. A speculated torque-vectoring all-wheel-drive system should keep fears of torque steer at bay, and larger brakes on the test mules indicate that bringing it all to a halt shouldn't be a problem, either. We do know that the hotter Focus will be among the "more than 12" vehicles that the new Ford Performance division will develop through 2020, and the RS will come to the US for the first time. However, US-spec RS models will likely be imported from Europe, which will keep numbers here low and will mean prices estimated to be around $30,000 or more. Until the official specs become available, at least enjoy watching this hot hatch's ability to slide.
