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.

NHTSA investigating 500k Ford and Mercury cars for lighting failures

The Ford Crown Victoria and Mercury Grand Marquis might be long gone as new models in showrooms, but the National Highway Traffic Safety Administration might check them out yet again for a potential problem. At the urging of North Carolina Consumers Council, the agency may open another investigation into the front lighting control module on vehicles from the 2003-2005 model years, and NHTSA estimates the issue could affect 517,945 vehicles. If the module stops working, it can cause a complete failure of all forward lighting, including the headlights. NHTSA previously investigated the issue in 2008 and 2009 but found no need for a recall, according to Bloomberg. Ford also extended the warranty on the part to 15 years or 250,000 miles. To prompt this new request, the North Carolina Consumers Council received a letter from a woman experiencing the module's failure. Upon further investigation, the council found 604 complaints of this problem on NHTSA's website, including seven crashes. Furthermore, the group has alleged that dealers told customers that the parts to perform the replacement weren't available, despite the extended warranty. According to the government agency, "A defect petition has been opened to evaluate the issue and make a grant or deny decision." Ford spokesperson Kelli Felker tells Autoblog via email, "We will cooperate with NHTSA, as we always do." You can read the council's complete letter to the Feds in PDF format, here. INVESTIGATION Subject : Loss of headlamp/exterior lighting Date Investigation Opened: APR 01, 2015 Date Investigation Closed: Open NHTSA Action Number: DP15002 Component(s): EXTERIOR LIGHTING All Products Associated with this Investigation Vehicle Make Model Model Year(s) FORD CROWN VICTORIA 2003-2005 MERCURY GRAND MARQUIS 2003-2005 Details Manufacturer: Ford Motor Company SUMMARY: The Office of Defects Investigation (ODI) has received a petition from the North Carolina Consumers Council, Inc. requesting a defect investigation of an alleged defect condition resulting in headlight and/or exterior lighting failure on 2003-2005 Ford Crown Victoria and Mercury Grand Marquis vehicles. The petition letter is attached for review. The petitioner alleges a defect in the lighting control module that powers the headlights which can result in the loss of vehicle headlights and/or all exterior lighting while driving. ODI has previously investigated this issue under PE08-066 which was closed without a defect finding.

Is this '47 Chevrolet a rat rod or a sports car?

These days there are plenty of vehicles that blur the conventional automotive class structures. For instance, was the Honda Crosstour a wagon or an SUV? And what exactly was the Nissan Murano CrossCabriolet? Regardless, those line-blurring cars (or trucks) are out there, and though this one didn't roll off a production line, it's still quite the automotive head-scratcher. Hailing from Missouri, this epic creation is one part mad science experiment, one part 1947 Chevrolet pickup, and one part '95 Mercury Cougar. Add it all up and you get an awesome truck-sports-car hybrid, complete with an outrageous wing and a V8 to boot. And interestingly enough, it's up for sale . RELATED: Check out this Wild-Styled Lamborghini Rat Rod So how does it all come together? According to the listing, the Chevrolet truck cab (which had previously been chopped) was sanded down to bare metal and given a thorough shellacking of clear coat. It was then melded together with the front end of a 1995 Chevrolet S10 pickup truck, and set low to the ground on Bilstein suspension drop spindles. Stance achieved. But instead of fielding an engine from either of those pickups, it pulls its heart from a 2005 Chevrolet Tahoe SUV—a big 5.3-liter V8 heart, that is. It comes backed-up to a GM Turbo 400 automatic transmission. Towards the rear however is where things get really interesting. A Copper Pearl coated tube frame chassis both attaches the rear independent suspension (a la Mercury Cougar) to the racy spoiler, as well as secures the rat rod's rear-mounted radiator, fan, and fuel tank. I'm not quite sure why, but it just looks glorious. RELATED: Reports Say Mid-Engine Corvette Will Arrive in 2018 Inside the vintage cab, the Chevrolet furthers its racing proclivities (it's said to have won burnout and auto-cross events) with a pair of harnessed racing seats, a drift brake, a detachable steering wheel, and a tachometer with oil and temperature gauges, but oddly no speedometer. The shifter is a crescent wrench. And its shift boot? That's a Crown Royal Purple bag. All in all, this grin-worthy Frankenstein creation tallies up bits and pieces from four different vehicles (five if you include the Camaro wheels), which make it truly a mash-up of epic proportions.
