2014 Roush Stage 3 Mustang

Up until now, it's been some years since I managed to get behind the wheel of the hot Mustangs tuned by the folks at Roush Performance. My memories of those vehicles are fond, as the Roush up-fits usually make for better-driving examples of the iconic Ford pony, with better-tuned suspensions, excellent short-shift kits and, of course, huge additions of power. The wake-your-neighbors aural characteristics of these cars have been nothing short of outstanding, too.
But in the years since my last experience with the Roush formula, Ford's own development team has churned out some pretty potent 'Stangs. We currently live in a world where the Blue Oval will sell you a Mustang with 662 horsepower from the factory, and the recently departed Boss 302 remains one of the best Mustangs - and best sports coupes - the Autoblog crew has ever driven.
So with great-driving and hugely powerful Mustangs coming straight off the line at Ford's Flat Rock Assembly Plant, does the Roush package still offer that extra special something to make it stand out? I spent a week with a Stage 3 coupe to find out.

NHTSA investigating Ford Fiesta for faulty door latches

The National Highway Traffic Safety Administration has opened a preliminary investigation on the 2011-2013 Ford Fiesta because the regulator has received 61 complaints from drivers, including one claim of an injury, about the doors on the subcompacts failing to latch and sometimes even flying open while driving. NHTSA has estimated that the problem could affect as many as 205,000 vehicles.
NHTSA is still gathering further data about the problem, but looking at the complaints so far, both front and rear doors appear to be potentially involved with the alleged failures. Among the reports, there are 12 claiming that the door opened while driving. Several also indicate the "Door Ajar" warning illuminating during this problem. The one purported injury happened when someone attempted to shut the door, and it bounced back.
Ford spokesperson Kelli Felker told Autoblog via email, "We are cooperating with NHTSA on this investigation, as we always do." Scroll down to read the report from NHTSA.

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.
