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.

Our love of SUVs is killing people in the streets

Americans are fond of supersized fast-food meals and colossal convenience-store fountain drinks, even though they're clearly bad for our health and U.S. adults keep getting fatter. We also like large vehicles, and our love affair with SUVs is killing people in the streets. According to a recent investigation by the Detroit Free Press/USA Today, the increase in SUV sales over the past several years coincides with a sharp rise in pedestrian deaths in the U.S. — up 46 percent since 2009, with nearly 6,000 people killed in 2016 alone. With SUV sales surpassing sedans in 2014 and pickups and SUVs currently accounting for 60 percent of new vehicle sales, it's no wonder Ford announced in April plans to cease U.S. sales of almost all passenger cars. And this followed Fiat Chrysler's move to virtually an all-truck, -SUV and -crossover lineup. While the Freep/USA Today investigation found that the simultaneous surge in SUV sales and pedestrian deaths comes down to vehicle size, it also points to a lack of action on the part of the National Highway Traffic Safety Administration (NHTSA), even though it knew of the dangers SUVs pose to pedestrians. Also blamed are automakers dragging their feet on implementing active safety features. Using federal accident data, the Insurance Institute for Highway Safety (IIHS) determined that there was an 81 percent increase in single-vehicle pedestrian fatalities involving SUVs between 2009 and 2016. Freep/USA Today's analysis of the same data by counting vehicles that struck and killed pedestrians instead of the number of people killed showed a 69 percent increase in SUV involvement. As far back as 2001, researchers at Rowan University forecasted a rise in pedestrian deaths as Americans began switching to SUVs. "In the United States, passenger vehicles are shifting from a fleet populated primarily by cars to a fleet dominated by light trucks and vans," the researchers wrote, with light trucks comprising SUVs.

Techstars Mobility brings transportation startups to Detroit

A new tech incubator is looking to combine the Motor City's automotive history with its evolving tech startup landscape. "Techstars Mobility, Driven by Detroit" kicks off its first round with 10 startups next week. Techstars is an established accelerator network with incubators around the world, and Detroit is a new addition. The projects center around mobility in some form, be it improving vehicles, moving goods, or working cars into the sharing economy in new ways. In return for a percentage stake in each company, Techstars provides mentorship, access to experts, seed money, and a collaborative environment. One startup we're particularly excited about is Motoroso. This site is like Pinterest for the car-obsessed, with boards replaced by garages that can contain photos and links to other projects. The site lets you follow brands – Chevy, Porsche, Ducati, and others already have profiles – as well as other users. For the Autoblog editors, Motoroso provides a new way to share stories, photos, and video, as well as a way to discover new products and interesting DIY projects. Take a look at the Autoblog profile and wander around the site to check things out. Another one of the startups, Classics & Exotics, is helping owners of interesting cars and would-be drivers connect in an Airbnb-style distributed rental program. Think of it as an auction catalog you can drive. Renters can specify the price, mileage, minimum driver age, and availability. Similar to Airbnb, Classics & Exotics provides each vehicle owner with $1 million in liability and damage protection. The company also vets renters for added peace of mind. Sounds like fun, and a cheap way to avoid a costly Craigslist or eBay mistake. Along similar shared-economy lines comes SPLT, a ride-sharing platform that finds people going where you're going and lets you hop in a car and split the costs. It's aimed at commuters but also has great applications for those looking for occasional one-way rides somewhere. SPLT notes that the system is a good way to meet new people – hopefully, good new people. Depending on how well SPLT keeps sketchy rides and riders out of the system, this could be a solid alternative to services like Uber and Lyft. This Techstars Mobility class has backing from corporate sponsors, including Ford, Honda, Magna, Dana, Verizon Telematics (Verizon has an offer pending to buy AOL, our parent company), and McDonald's.
