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.

The 1965 Ford Mustang could have looked a lot different

The 1965 Ford Mustang is unquestionably an automotive design icon, and nearly every generation of Mustang has some connection to that original car. Because it's such a universally-known vehicle, we were amazed to see all the different designs that were being considered. Head of Ford's archives Ted Ryan recently shared photos of design proposals for the original Mustang on Twitter that he and Jamie Myler found, and we reached out to them to find out more. As Ryan initially noted, the photos were taken on August 19, 1962, and they are proposals for the Ford Mustang. Apparently Ford had committed to doing a Falcon-based youth-oriented car at this point, and it did have plans to launch the car in 1964 for the 1965 model year. But after having little success with early design proposals, the company asked all of its design studios — the Advanced Studio, Lincoln-Mercury Studio and Ford Studio — to submit proposals. With only about two years before the planned launch, Ford was understandably short on time, and it's believed that the studios only had a month to create and present these designs. Lincoln-Mercury design proposal View 8 Photos The majority of the designs, a total of five, came from the Advanced Studio, and part of this was because they already had a couple of concept designs in reserve it could present. Two other models representing three design possibilities came from Lincoln-Mercury, and just one model with two options came from Ford. The Advanced Studio proposals are shown in the gallery at the very top of this article, and the Lincoln-Mercury and Ford proposals are in the gallery directly above this paragraph. The Advanced Studio's most radical design is the one that was clearly related to the Mustang I concept that would be shown later that year with huge wraparound rear glass, turbine-inspired bumpers and enormous side scoops. The other proposals from the studio were more conservative, featuring simple lines, grilles reminiscent of the Falcon, and one even borrowing the jet-thruster-style taillights made famous on the Thunderbird. Lincoln-Mercury had some impressively bold designs, particularly its fastback that had buttresses to extend the shape all the way to the tail. This car had two different side trim possibilities. The other Lincoln-Mercury design was toned down a bit, but had two interesting possibilities for side detailing, as well as some crisp, low-profile tail fins.

eBay Find of the Day: Craterface's '49 Mercury convertible from Grease

Here is your chance to own your very own piece of greased lightning. Well, not the Greased Lighting, it's actually the black, flamed 1949 Mercury convertible that races against John Travolta in the classic 1978 movie Grease, and it's for auction on eBay Motors.
While it appeared in the film's exciting drag race in a Los Angeles storm drain, the hot rod was reportedly lost until last year, when the seller found it as a shell. He verified that it was the actual car with original builder, Eddie Paul, and sent the car for a complete restoration.
The auction includes original parts like the exhaust tips used in the movie and bent bumper from when it hit Travolta's car in the scene. The restorer recreated the scorpion stickers on the doors, razor hubcaps and license plate. He also installed a 1949 Mercury 255-cubic-inch (4.2-liter), flathead V8 and three-speed manual transmission with overdrive.
