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.

Hennessey showcases F-250 VelociRaptor SUV

With automakers embracing smaller and smaller crossovers with each passing year, it'd be all too easy to forget about the Ford Excursion. Bigger than the Expedition (or just about anything else on or off the road), the Excursion was based on Ford's Super Duty truck chassis to put even the likes of the Chevy Suburban, Nissan Armada, and Toyota Sequoia to shame. It ceased production ten years ago now, but Hennessey is bringing it back – sort of. Feast your eyes on the Hennessey VelociRaptor SUV. The design calls for a very fullsize, truck-based sport-ute based on the Ford F-250. Only instead of a pickup bed, it's got four proper side doors and a covered cargo bay with a pair of barn doors at the back. Hennessey will fit it with three rows of seats to accommodate seven or eight passengers, and of course it'll offer a range of upgraded engines as well. What starts out with a 6.2-liter V8 producing 411 horsepower can be supercharged all the way up to 600 or even 650 horses. For those who don't want to spend their life's savings at the pump... well, this probably isn't the right choice of automobile, but Hennessey will offer an enhanced 6.7-liter PowerStroke diesel with 440 hp and 880 pound-feet of stump-pullin' muscle. Naturally there'll be other visual and mechanical upgrades on offer as well, but none of this will come cheap – or fast for that matter. Hennessey will take six months to put one together, and demand nearly $160,000 for the conversion.

How the Ford Shelby Mustang came to be

Even as rumors swirl that the next-generation of high-performance Ford Mustang will drop the Shelby name, Ford has released a short video telling how the legend of the Shelby Mustang came to be. In its latest installment of its video series entitled Mustang Countdown, Ford dug up some footage from Carroll Shelby to give a little insight into how this automotive icon was created.
While it's definitely interesting to hear the late legend tell the story in his own words (including numerous references to the 1964 Mustang as a "secretary's car"), it's also pretty funny learning exactly how the Shelby GT350 got its name in the first place - a name allegedly making a comeback as the replacement for the current Shelby GT500. As development work continues on the 2015 Ford Mustang, the Shelby video posted below shows that the automaker is always looking at its past - even as it looks ahead to the future.
