Watch Tanner Foust hustle the Fiesta ST 'round the 'Ring

The last time we saw Tanner Foust at the Nürburgring he was sloshing an SVT Raptor from kerb to kerb. Sticking with Ford but swapping keys, this time the drift champion and Top Gear USA host goes to the opposite end of the manufacturer's tuner garage and plucks a Fiesta ST for 'Ring duty.
The 179-horsepower front-wheel-driver acquits itself well by the end of the video. But be warned, Foust doesn't set a 'Ring time and it's shot like a commercial... because that's what it is. Still, you can enjoy all two minutes and 31 seconds of it below.

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.

Feds looking into Ford Explorer exhaust leak complaints

There may be a burgeoning problem with exhaust leaks in the 2011-2014 model year Ford Explorer. The National Highway Traffic Safety Administration is examining multiple complaints of a gasoline smell in the cabin of these SUVs. However, the exact cause of this problem is still unknown.
"The agency is reviewing all available data and will take appropriate action as warranted," said a NHTSA spokesperson in an email to Automotive News. Owners seem to generally complain on the regulator's website of the smell entering the cabin through the air vents. At this time, the government organization has not yet opened an official investigation into the problem, though. When it does begin inspecting vehicles, NHTSA posts a detailed breakdown of its public data online.
Similar problems have been reported about the Explorer in the past, though. In 2013, Ford issued a recall for the 2013 model year of the SUV due to a fuel leak that could cause drivers to smell a gasoline odor and repaired them again later for another possible leak. In response to Autoblog's questions, Ford responded via email: "We are not aware of a NHTSA investigation. We are currently reviewing the case and in the event that any action is required, we will address it promptly."
