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.

Ford GT to be revived, Le Mans battle upcoming

Ford dominated the 24 Hours of Le Mans from 1966 to 1969, scoring four consecutive wins. Wouldn't it be great if the Blue Oval could go back to France for the 50th anniversary of that performance and show it can still compete in international endurance racing? Actually, the latest rumors indicate that could be exactly the case, and the car taking that checkered flag could be another revival of the Ford GT.
As the rumblings go, Ford wants to use a new supercar to take another crack at Le Mans, after considering some other possible alternatives. Substantiating these musings are reports that a Blue Oval rep was reportedly on hand for a recent meeting about 2016 GTE-Class rules, according to Road and Track. That would put the new GT in the same racing class as the Corvette, Ferrari 458 Italia, Porsche 911 and others.
It's not all about racing, though. If you win on Sunday, you want something to be able to sell on Monday. The revived GT is reportedly still a mid-engine supercar, but the exact engine is unclear. It's possible that it could even be shown or announced at the Detroit auto show in January, according to Motor Trend.

Hennessey Ford GT sets 267.6-MPH record at Texas Mile [w/videos]

The record-setting Hennessey-powered camouflage Ford GT we showed you at this time last year headed back to the Texas Mile and managed to bring home yet another record. As you may recollect, last year saw Mark Heidraker's machine sprint to a record 257.7 mph thanks to propulsion from its twin-turbo 5.7-liter V8. The big mill sucks down race gas, and this year the creation pulled off a 267.6-mph run over the weekend. That feat set a new record for the event. Something tells us neither Heidraker nor Hennessey are done squeezing more thrust from this machine.
This particular Ford GT has already gone through a number of permutations. Hennessey started by tweaking the factory supercharger set up before abandoning the blower in favor of two turbos. Since then, the crew has poked and prodded it to coerce as much grunt as possible out of the car. We expect Hennessey will probably come out with a video of the record-setting run shortly, but in the meantime, you can see a couple of videos of the car's runs in Texas below (one of which actually captures the record run). Enjoy.
