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 Focus Electric hides in plain sight

The styling changes to the 2015 Ford Focus were shown off at the recent Geneva Motor Show, so what the EV version looks like is not that much of a surprise. Still, the 2015 Focus Electric is making its world debut here at the New York Auto Show, so we wanted to know what changes we are looking at compared to both the internal combustion engine version and the earlier EV models.
The exterior visual distinctions between the ICE and EV are minimal, and basically nonexistent from the A-pillar to the rear. Up front, you can see the charge port, of course, but the front fascia has also undergone a bit of an adjustment. The front doesn't have the ICE version's flattened grille and the EV's Ford logo creates a bump in the hood line where none exists on the ICE. The 2015's grille is also different than the one on the 2014 Focus Electric, being slightly smaller (you can see this better if you compare pictures in our new gallery above to these of the 2011 Focus Electric and these of the gas-powered 2015 Focus).
The updated 2015 interior - which we couldn't access ourselves - has things like a new center stack, improved cupholders and is basically identical between the gas and electric models. With the car off, you can't even tell if you're in an EV or ICE, Seema Bardwaj, the US brand manager for the Focus, told AutoblogGreen. The only things that are different, she said, are extra menu screens to show EV powertrain information to the driver.

Winnebago re-introduces classic Brave RV [w/video]

Winnebago is saying 'Let's do the time warp again,' using its new Brave RV to do it – have a look at the first Winnebago RV from 1966 and you'll know exactly where this one comes from. The modern version of this swinging sixties motorhome is accurate from its size, either 26- or 27-foot version, to its trademark eyebrow above the front windshield. The foldaway bunk above the front seats that necessitated the eyebrow design has been updated, and is now a power bed that descends from the ceiling. It is among a set of standard features that also includes a 19-foot motorized awning, leveling jacks at all four corners, heated mirrors, LED ceiling lights, two available floorplans and detailing like a workstation for the front passenger, a sliding dash cluster and and a waterfall countertop in the kitchen with built-in extensions. The Brave sits on a Ford F53 chassis complete with its Triton V10 engine and five-speed automatic transmission. No word yet on any potential diesel alternatives. Naturally, that 1966 price of $4,000 will also come in for an update, but the company hasn't yet revealed it. The good folks from Winnebago will be happy to take you on a thorough personal tour of the Brave in the video below. This content is hosted by a third party.
