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 bringing 10 custom Transit Connects to SEMA

With 57 vehicles planned for its SEMA display, it comes as little surprise that Ford has plenty of teasers for its show cars. After showing us what it has in store for the Mustang, Fiesta and Focus ST, now we're getting a look at some of the custom creations based on the redesigned 2014 Transit Connect van.
These nine Transit Connects are decked out to various degrees of customization, but our favorite might be the chopped and lowered Transit Connect from Mob Steel (shown above), which has a similar slammed stance that we see on some custom VW Buses. On the opposite extreme, LGE & CTS Motorsports has jacked up a Transit Connect to make a Cross Country cruiser that we wouldn't mind taking on a road trip.
There are seven other teasers from various companies, and you can check them all out in the gallery above or in the press release below. Ford is also promising a tenth Transit Connect for SEMA, so stay tuned for that as well.

Uber hopes facilities in Detroit will help shape its autonomous future

Hot off the heels of unleashing its fleet of self-driving vehicles in Pittsburgh, PA, Uber announced plans to open a new facility in the Detroit, MI area, reports Automotive News. The new facility was announced at an event hosted by Society of Automotive Engineers in Detroit, MI. Uber's vice president of global vehicle programs Sherif Marakby revealed the news, reports Automotive News. The facility is meant to help the ride-sharing company collaborate with suppliers and automakers in the area. There's no word on where Uber will build the new facility or how big it will be, as those factors have yet to be determined. Just like Pittsburgh, PA, Detroit, MI could become another testing ground for the ride-sharing company. The latest move to open a facility in the Detroit area comes after Uber offered users in Pittsburgh the chance to ride in one of its autonomous vehicle as it looks to gain vital real-world testing. Uber is utilizing a fleet of modified Ford Fusions. Earlier this year in April, the automaker announced a partnership with Google, Lyft, Uber, and Volvo to develop autonomous cars. A new facility in Detroit would strengthen the partnership and help Uber, as well as Ford put autonomous vehicles on the road faster.
