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.

Car Club USA: Louisiana Mudfest

There's nothing quite like mudding. Big tires, huge power, and crazy-wild gearheads that like to throw down on a mud pit almost as much as a thirty rack of Coors. In the latest, and some might argue greatest yet episode of Car Club USA, we head to Louisiana to throw some dirt at Mudfest. As Louisiana's one and only Mouth of the South puts it, "If you don't mud ride... go to Texas I guess." Joining The Mouth and friendly rivals The Most Hated Mud Sluts, we dive in. Beyond the obvious V8 blasting and tractor-tire spinning, those who know best describe Mudfest as, "Good cooking, good friends, good fun, and a lot of partying." It's a motorsport spectacle unlike any you're likely to find up North or out West, though no less impressive to behold. Follow along with the fun, the impromptu drag racing, the trash talking, and the mechanical madness. And find out why, at Mudfest, "if we don't tear it up, we ain't done it right." Each Car Club USA episode features a different car club or event from across the US, where passionate owner communities gather to share automotive experiences and embark on incredible adventures.

Ford, Volvo, Google, Uber and Lyft form self-driving alliance

Five companies arguably leading the worldwide effort to develop autonomous cars said Tuesday they're forming an organization to lobby the federal government to better prepare America's roads for self-driving technology. The founding members include some of the biggest companies in the automotive, autonomous, and ride-sharing realms – Ford, Google, Lyft, Uber and Volvo. Operating as the "Self-Driving Coalition for Safer Streets," they aim to work with lawmakers and regulators to clarify a disparate set of rules and regulations at both the state and federal levels that could hinder the deployment of autonomous cars. "The U.S. risks losing its leading position due to the lack of federal guidelines for the testing and certification of autonomous vehicles." – Hakan Samuelsson David Strickland, a former administrator of the National Highway Traffic Safety Administration who issued the first set of autonomous-related policies in that role (pictured below), will serve as the group's counsel and spokesperson. "The best path for this innovation is to have one clear set of federal standards, and the Coalition will work with policymakers to find the right solutions that will facilitate the deployment of self-driving vehicles," he said in a written statement. In January, Transportation Secretary Anthony Foxx said his department would accelerate efforts to craft such federal standards. Those efforts include holding two public hearings on standards, the second of which is scheduled to be held Wednesday in Palo Alto, California. Foxx signaled the intent to deliver them by June. Google has been leading the efforts to ensure such standards are national in scope, warning their cars could run afoul of state-specific laws should they cross state borders or if standards varies between the federal efforts and regional ones. The complexity of such efforts was underscored recently, when NHTSA agreed that Google's software could be considered the driver of a vehicle for the purpose of meeting federal motor vehicle standards, an interpretation that would conflict with preliminary California rules that mandate a licensed driver operate a self-driving car that comes equipped with human controls like a steering wheel and brakes. At South By Southwest last month, Jennifer Haroon, Google's self-driving car business leader, said the company couldn't accomplish its goals under those regulations.
