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.

Mercury Cougar from Bond film 'On Her Majesty's Secret Service' is up for auction

To a James Bond fan, this is a very cool and important car. This 1969 Mercury Cougar XR7 up for auction by Bonhams was one of three used during the filming of 1969's "On Her Majesty's Secret Service," the one-and-done film starring George Lazenby that's a dark horse favorite among many Bond fans (this one included, there's a Japanese-market 'OHMSS' poster hanging behind me as I type this). However, this was not James Bond's car in the movie. He drove an Aston Martin DBS, including in the film's pre-titles sequence when he follows Tracy di Vicenzo driving her bright red Cougar. She would go on to rescue him with it in Switzerland (hence the skis), sacrificing its pretty red paint and body work in a demolition derby on ice that they use to shake Blofeld's Benz-driving goons. Later, after getting caught in a blizzard, they seek refuge in a barn -- a pivotal scene in the film and one where this particular Cougar was apparently used.  ON HER MAJESTY’S SECRET SERVICE | Ice Car Race However, even without the Bond connection, this Cougar is a very cool car. It was one of only 127 in 1969 to be fitted with the top-of-the-line 428 CobraJet Ram Air V8 rated at 335 horsepower. Tracy had a serious muscle car. Bonham's doesn't seem to have thought to provide a Marti report, but I'm guessing the build of XR7, convertible and a color combo of matching red exterior and interior wasn't exactly a common one. Well, we know there were at least three. With skis and French number plates, too.  As for the '69 Cougar itself, this was the only year it looked like this: it got a new body for '69 that would last two years, but the horizontal grille slats that extended over the headlight doors (so cool!) didn't carry over to 1970. It looked worse, and it could easily be argued that it was only downhill from here for the Cougar.  The auction is set for December 16 and Bonhams is estimating a sale price of between $130,000 and $200,000. That certainly makes sense given the rarity of a CobraJet Cougar, the film connection and the complete restoration undertaken by the man who found it in a classified ad in the late 1980s. He originally just wanted it for the engine until he discovered the Bond connection. I actually saw this very car at the 50th Anniversary "Bond in Motion" exhibit at the Beaulieu Motor Museum in England back in 2013 (pictured below). There's also a model of the thing sitting next to me.

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.
