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.

2016 Ford Explorer order guide revealed

The configurator for the refreshed 2016 Ford Explorer is already up and running. However, if you're the type of person that really likes to dig into the nitty-gritty of a vehicle's features, then the order guide for this latest Ford is now available (pictured right). While the documents don't list fuel economy, engine power or pricing, they give a precise idea of all of the differences separating each of the five trim levels: Base, XLT, Limited, Sport and Platinum. In addition to the tweaked styling across the board, even the Base model now features a rearview camera with a washer. There are also three new colors available: Shadow Black, Blue Jeans Metallic and Guard Metallic. Base, XLT and Limited trims are available with either a 3.5-liter V6 or new, optional 2.3-liter EcoBoost four-cylinder. All of them are mated to a six-speed automatic, and all-wheel drive is optional with either engine. The new Platinum trim basically loads the Explorer up with everything imaginable. Power comes from the 3.5-liter EcoBoost V6, matched with all-wheel drive. Plus, the Platinum trim gets standard luxuries like a dual-pane moonroof, adaptive cruise control, a premium sound system and Ford's super-soft Nirvana Leather covering the seats. There are also some new tech features throughout the rest of the lineup. For example, an updated auto-parking system is also available on the Limited but comes standard on the Platinum. Furthermore, a 180-degree front camera and second-row USB charging are optional on the Sport but are standard on the Limited and Platinum. Check out the gallery for even more of the changes.

Shelby GT500 and Roush Stage 3 go head to head at the drag strip

The Ford Mustang is a brilliantly affordable source of horsepower, with a base 300-plus-horsepower version available for well under $30,000. Jumping up to about $35,000 will get you a solid 420 horsepower from a high-revving V8, while those with some extra disposable income can get a pair of 600-plus-horsepower monsters. Both the Roush Stage 3 with its Phase 3 package and Ford's factory Shelby GT500 even crest the 650-horsepower mark, with 675 and 662 ponies, respectively.
Naturally, someone needed to find out which of these hi-po Mustangs was the quickest. And while this video is quite obviously a dealership commercial, at least there's some solid drag racing between two of the most powerful performance machines available for under $100,000.
With two NHRA drag racers at the wheel, the Stage 3 and GT500 go head to head for three races. Scroll down below to see the results in the full video.
