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.

Exceptionally rare '65 Ford GT40 Roadster prototype up for auction

Think of mid-engined supercars and your mind is bound to gravitate towards Europe, but the United States has been known to make a handful from time to time - exceptional vehicles from the likes of Vector, SSC, Mosler, Hennessey, and Saleen. But long before any of those came around, Ford famously became obsessed with beating Ferrari at its own game, leading to the development of the iconic GT40.
The story is well known, sending Ford to the checkered flag at Le Mans four times in a row in the late 1960s. Ford and Shelby also built over 100 for public consumption, but just four of them were roadsters. Of those only one remains in original condition, and now that exceedingly rare example going up for auction.
Consigned to RM Auctions for its mid-August sale during Pebble Beach weekend in Monterey, California, this 1965 model is the first GT40 Roadster built. It was used as a development and demonstration vehicle for Ford and Shelby. Carroll Shelby himself drove Henry Ford II in this very car during one of many test and demo events, this time held for Ford's board of directors in Los Angeles.

2015 Ford Mustang to make world debut on Dec. 5 [w/video]

Between a bevvy of spy shots, speculative renders and insidery images from the halls of Car and Driver, we've got a pretty decent idea of what the 2015 Ford Mustang might look like. Still, we're excited to see the real deal as soon as possible.
Turns out that Ford has told us just when that first official look might come, too, although it has chosen somewhat of a backdoor fashion for dropping the news.
The video below popped up on the Ford Mustang YouTube channel this morning, promoting a social media effort called #MustangInspires on. The video and hashtag ask fans of the pony car to share pictures of the car - or "photographic stories of inspiration" - on Instagram, Facebook, Twitter, etc. But the truly interesting part of the video description is that which mentions taking "the cover off the all-new Mustang" on December 5. Consider our calendars marked.
