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.

Signature Edition Ford Shelby GT500 Super Snake to get limited production run

The upcoming Ford Shelby GT350 Mustang keeps grabbing a horde of headlines thanks in no small part to the pony car's 5.2-liter V8 with a flat-plane crankshaft, magnetic dampers and other go-fast goodies. However, as the new contender enters the ring, Shelby American is saying goodbye to the old GT500 and the company's even more powerful Super Snake version with its new Signature Edition model. Limited to a total of 50 conversions on 2007-2014 coupe or convertible GT500s, the Shelby American Signature Edition packages some of buyers' most common choices into a single vehicle with a few extra touches, as well. The heart of it all is a 3.6-liter Kenne Bell supercharger to replace the V8's standard blower and take power up to a claimed 850 horsepower for the latest models. To keep things running at the proper temp, the mill gets an upgraded radiator, heat exchanger and aluminum cooling tanks, too. The rear brakes are also improved to slow this stallion down. In addition to the boosted power, buyers get some extra style. These special Super Snakes are available in all of the colors available on them from Ford, plus a range of shades for the stripe, and the wide body package can also be added as an additional option. The limited version wears 20-inch forged wheels from Weld that are 9.5-inches wide at the front and 10.5-inches at the rear and feature Signature Edition center caps. Inside, there's a commemorative badge with Shelby's signature on the airbag cover and Signature Edition floor mats. Finally, customers get a day training at the track to learn how to control this beast as part of the package. Orders for the Signature Edition are being accepted through January 31, 2015, and the modded model is priced at $44,995.00, which is in addition to the price of the stock GT500.

PickupTrucks.com's latest test results in a familiar winner [w/video]

PickupTrucks.com has gone and thrown the latest batch of half-ton pickups into a cage match to see who would come out on top. The site put the 2014 Chevrolet Silverado 1500, GMC Sierra 1500, 2013 Ford F-150, Ram 1500, Toyota Tundra and Nissan Titan through a battery of tests. Those included 0-60 miles per hour acceleration, 60-0 mph deceleration, fuel economy, a hill climb, and payload and towing. They even threw the rigs on an autocross course to evaluate overall handling. Each truck was given points based on how it scored in each evaluation.
Who came out on top? Somewhat surprisingly, the 2013 Ford F-150 walked away with the gold, though fewer than 50 points separated first and fourth place. Head over to PickupTrucks.com to read the full evaluation and the final results. You may be shocked to see exactly where some of the segment's newest additions placed. You can also watch a video on the test below.
