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.

2015 Ford Mustang Convertible makes inappropriate appearance in Detroit [w/video]

With the polar vortex fresh in the minds of Autoblog's Detroit-based staff, we're finding it funny that any manufacturer would choose January in the Motor City to show off a new and highly anticipated convertible to the general media and public for the first time. But Ford has done just that, giving us our first real peek at the new Mustang Convertible in the flesh.
The new Mustang Convertible is more or less unchanged from the standard coupe, with some subtle styling tweaks to accommodate the retractable soft top. Engine and transmission choices are identical to the hardtop, although we should expect slightly lower performance due to the hardware for the roof. Like the coupe, neither prices nor performance metrics have been published yet for the convertible.

Ford F-150 RaptorTrax is Ken Block's ultimate snowmobile

Even when Ken Block isn't starring in the latest Gymkhana video or tearing up Global RallyCross courses, he's finding new ways to redefine "awesome" as it applies to motorsports. For evidence of this, look no further than Block's latest Monster-badged creation, the Ford F-150 RaptorTrax.
Billed as the "world's fastest snowcat," the RaptorTrax started life as a Ford F-150 SVT Raptor, and then a set of Mattracks were put in place where the truck's bead-locked wheels and meaty rubber once resided. The goal was to create a truck that made it easier - and presumably more fun - for Block and his buddies to hit the slopes on their snowboards. Aside from the obvious track upgrades, this truck also received a Whipple supercharger, full roll cage, Recaro seats, an in-bed snowboard rack, a roof basket and a rear-mounted winch - you know, just in case something or someone actually manages to get this truck stuck.
The RaptorTrax will be on display later this week at the Winter X Games in Apsen, CO, but we'll have to wait until next winter for a full Block-worthy video of the truck. A full press release from Hoonigan Racing Division is posted below, and a high-res image can be found by clicking above.
