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.

Consumer Reports: Ford Fusion fun but flawed; Mitsubishi i-MiEV slow, chintzy [w/videos]

Waiting for a Ford compliment from Consumer Reports these days is like waiting for a low-cost new product from Apple. So we weren't really expecting a glowing review of the 2013 Ford Fusion when CR got its hands on the car. The institute's crew bought three different versions of the Fusion (Hybrid, 1.6-liter EcoBoost and a Titanium with the 2.0-liter EcoBoost) to put through its barrage of tests, and while we aren't too surprised by some of the findings, they're still interesting nonetheless.
CR praises the Fusion for its "eye-catching" design and says that the sportier Titanium trim level is the best-handling midsize sedan they've ever tested, but that's about where the good news ends for Ford. The Fusion Hybrid also posted the best-ever fuel economy CR has recorded in a midsize sedan, but the only problem is that their number was 39 miles per gallon combined - far less than Ford's 47 mpg rating for city, highway and combined. As expected, CR also dinged the Fusion for its MyFord Touch, but some of the other gripes about the car include a cramped cabin and poor fit and finish.
Other Ford products tested this time around include the Focus Electric and C-Max Hybrid. Like the Fusion, CR's observed fuel economy of 37 mpg for the C-Max fell well short of Ford's advertised 47-mpg rating, and both cars were criticized for the use of MyFord Touch. CR notes that the Focus Electric's interior is also cramped, with the battery pack taking up a lot of cargo space.

2019 Chicago Auto Show photo gallery: All of the grilles

Do you like trucks? How about grilles? Like really big, shiny, chromey, in-your-face, could-be-made-by-Broil-King grilles? Well, the Chicago Auto Show is the place to be. Traditionally known as the truck show of the annual auto show circuit (at least those covered by national media), Chicago has what seems like a small national park's worth of acreage devoted to both consumer and commercial trucks. From humble extended cab Ford Rangers to a mammoth F-650 with cherry picker sprouting from its aft quarters, there's bound to be a truck for everything. And they all have grilles. So above is our gallery devoted to them, because hell, why not? Should you want to know about the trucks attached to those grilles, check out our coverage below.
