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.

Chicago Auto Show: The really big reveals from shows past

The 2024 Chicago Auto Show may seem like a shell of its former self, but it still holds the title of the largest consumer auto show in the United States. It didn't get that reputation simply by being efficiently produced or convenient for locals desperate for something to do in February — it earned it over decades of breaking automotive news and powerhouse reveals, eventually earning an informal designation as America's truck show.  2024 may be a down year for Chicago, but let's not forget all of the great things that have come out of it, historically. Here's a look at some of our staff favorites. Bet you didn't know about a few of these cars that were first revealed in the Windy City.    2008 Dodge Challenger SRT-8  I didn't just pick this one as a former Challenger owner, but instead to illustrate just how many cool Chicago debuts we take for granted. Chrysler often chose its home turf to debut new cars, so the few times its unveilings happened elsewhere tend to stick in our minds. The first Challenger SRT-8 was kind of garbage, if we're being honest. I mean, who buys a race-bred, V8-powered muscle car without a limited-slip differential? But the SRT-8 formula evolved over time into something truly special, and what we saw in Chicago was essentially the early version of the Scat Pack, which was ultimately very successful for Dodge. And who would have thought we'd be here, 15 years later, still talking about that debut? And still loving these big Mopars, flaws and all. — Associate Editor Byron Hurd SHO time in Chicago IÂ’ll always have a certain fondness for the return of the Taurus SHO at the 2009 Chicago Auto Show. Chicago has always leaned truck and van heavy for press reveals, but every now and then, as this list illustrates, something spicy would appear. The return of the SHO as a high-powered successor to the original that ran from 1989-1999 gave enthusiasts hope for FordÂ’s performance business, especially for sedans. With a 3.5-liter EcoBoost V6 packing 365 hp, all-wheel drive and five-spoke wheels, the SHO was a nice upgrade from the lower-rung Taurus models. It was a bit more sedate than the original SHOÂ’s Yamaha-sourced V6 that teamed with a five-speed manual transmission, but still a worthy response to the Chrysler 300, Dodge Charger and later the Chevy SS. The SHO — Super High Output — begat things like the Fusion ST and gave Ford solid four-door performance for the rest of the decade.

2015 Ford Mustang earns Five Stars from NHTSA [w/video]

We already know that the latest Ford Mustang is a pretty potent pony car in terms of its performance potential, but according to the government, it's a safe choice too. The National Highway Traffic Safety Administration recently released its New Car Assessment Program crash test results for the 2015 'Stang coupe, and it came away with top five-star overall ratings in every evaluation. The Mustang received a five-star overall score and five stars for its frontal, side and rollover ratings. The only minor ding was a four-star result just for the backseat in a side barrier crash. According to NHTSA, "Although not included in the star rating, the rear passenger's thoracic rib deflection was elevated." You can check out the full NCAP evaluation, here. According to Ford, the latest Mustang has twice as many airbags and crash sensors as the outgoing model. NHTSA also likes that the pony car offers a rearview camera and forward collision warning – two of the technologies that the agency recommends buyers getting for added safety. Watch the car crash in the video below. 2015 MUSTANG EARNS HIGHEST VEHICLE SAFETY RATING FROM NATIONAL HIGHWAY TRAFFIC SAFETY ADMINISTRATION National Highway Traffic Safety Administration awards the all-new 2015 Mustang a five-star Overall Vehicle Score in its New Car Assessment Program All-new Mustang has twice as many airbags, twice as many peripheral crash sensors and additional pretensioning safety belt technology compared to the outgoing model The new Mustang is the first car to offer four-, six- and eight-cylinder engines that each produce at least 300 horsepower – a 300-horsepower 3.7-liter V6, a more powerful 435-horsepower 5.0-liter V8, and an all-new 310-horsepower 2.3-liter EcoBoost® engine DEARBORN, Mich., Feb. 11, 2015 – The 2015 Ford Mustang received a top safety rating from the National Highway Traffic Safety Administration (NHTSA). The 2015 Mustang earned a five-star Overall Vehicle Score in NHTSA's New Car Assessment Program (NCAP) testing. The New Car Assessment Program is the National Highway Traffic Safety Administration's evaluation program for new vehicle designs established to test for performance against safety threats. Now on sale at Ford dealers, the all-new 2015 Mustang received five stars in the frontal crash test, five stars in the side crash test and five stars in the rollover crash test. "The new Mustang was built from the ground up," said Carl Widmann, Mustang chief engineer.
