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.

Reflecting on the Ford GT on its 10-year anniversary

Ten years ago, during the bright-eyed enthusiasm of the early 2000s and before the collective automotive industry did its best Titanic impression, we had the Ford GT. An everyman's supercar like there'd never been (remember, this was before 638-horsepower Corvettes were a thing), the GT arrived with a supercharged, 5.4-liter V8 that produced 550 horsepower and graced this retro-styled rocket with an easy, sub-four-second sprint to 60 miles per hour.
Equal to the GT's performance were its looks. Inspired by the GT40 racers that dominated Le Mans and bested Ferrari in the 1960s, the sleek, low, almost-reptilian look of the GT was the absolute pinnacle of the retro styling that so defined the early 2000s.
Crank and Piston put together a video celebrating the ten-year-old GT, arguing that Ford is a bit too busy with the next-gen Mustang, which turns 50 next week, to do it themselves. In the short clip, there is gratuitous engine noise and supercharger whine, not to mention scenes of the white-on-red GT prowling the deserts and streets of Dubai. It's a bit short, but very nicely shot. Scroll down, have a look and be sure to turn up those speakers before getting started.

2020 Ford Escape, Lincoln Corsair ace crash tests, earn Top Safety Pick from IIHS

The redesigned 2020 Ford Escape and its platform-mate, the 2020 Lincoln Corsair, have both just completed their bout of crash tests at the hands of the Insurance Institute for Highway Safety, and while they did not emerge unscathed, they did come away with the agency's Top Safety Pick Award. One caveat: The rating only applies to the Escape equipped with the available LED headlights, which were deemed Acceptable. Similarly, the Corsair needs the available curve-adaptive LED headlights, also rated Acceptable, in order to achieve Top Safety Pick. The Escape's standard halogen headlights scored only a Marginal rating, while the Corsair's base LED headlights were deemed Poor due to glare. Those low headlight ratings knock the vehicles out of contention for Top Safety Pick. Had either vehicle offered headlights able to achieve a Good rating, that would have been enough to get them the agency's Top Safety Pick+ rating. Outside of their headlights, the 2020 Escape and Corsair acquitted themselves well. The Escape saw a big improvement in the difficult small-overlap front crash test, going from a Poor result in the previous generation to Good with the new one. The Corsair performed identically, and both achieved Good ratings in all six crash tests. The IIHS also tests automatic emergency-braking systems, and the standard and optional systems in the Escape and the Corsair both earned Superior ratings.
