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.

Get a taste of Ford GT ownership from Dust Devils

It seems that the automotive world might be right on the cusp of getting some kind of follow-up to the Ford GT. It might not be called the GT or even use the coupe's retro look, but rumors point to such a beast being on the way. If the future halo model can inspire as much adoration among fans as the previous ones, then the Blue Oval is sure to have another winner on its hands. To get idea just how closely GT owners are bonded to their cars, take a ride with the participants in the ninth Ford GT National Rally in this short documentary titled Dust Devils. The owners convened with over 80 of the retro supercars in Las Vegas, NV, to admire the coupes and give them a workout on the desert roads. It's especially nice to see the drivers of these limited production Fords unafraid to take their cars to the track and stretch their legs a little.

The long, low-slung look is simultaneously menacing and lithe, and the growl from the latest model's supercharged V8 is nothing to complain about either. Get just the slightest taste of what it's like to have one of these halo Fords in this clip, from the people that love them the most.

Tanner Foust tackles 'Ring in SVT Raptor

Here's a math problem: if Tanner Foust has a 24 hours to kill in Germany and one blue Ford Raptor, how long will it take him to decide he wants to lap The Nürburgring? Extra credit if you can get your answer precise to the millisecond.
A very truck-like and slidey lap of the 'Ring is exactly what happened when the Ford-sponsored rallycross driver took time off from set-up duties for his 'day job.' Thankfully no one even thought to worry about posting a time, but you can watch some Raptor skid marks getting laid down between the kerbs in the video below.
