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.

2014 Ford Fiesta ST priced from $21,400* [w/poll]

The 2014 model year brings a whole host of changes to Ford's Fiesta B-Segment fighter, the most important of which (to our enthusiast eyes, anyway) is the addition of a potent new ST model. The US-spec hot hatch was first shown at the 2012 Los Angeles Auto Show last November, and thanks to Ford's build-and-price site, we've now learned that the Fiesta ST will slide in at $21,400 when it goes on sale later this year (*not including $795 for destination).
Under the hood of the ST is a turbocharged 1.6-liter EcoBoost inline-four good for 197 horsepower and 214 pound-feet of torque, mated solely to a six-speed manual transmission. Ford hasn't released performance data on its pint-sized puncher just yet, but know that these numbers make the Fiesta ST ever-so-slightly more powerful than the larger Volkswagen GTI while returning an estimated 34 miles per gallon on the highway.
Elsewhere in the lineup, the standard Fiesta also gets a smattering of improvements for the 2014 model year, including a new 1.0-liter three-cylinder turbocharged engine and revised exterior styling. Pricing for the 2014 Fiesta sedan starts at $14,000, with the five-door model adding $600 to that number (again excluding the $795 destination fee).

Jay Leno's Garage goes eco with Ricardo HyBoost

"Now before you turn away, this is not another boring hybrid car thing..." Despite the slightly defensive introduction from Jay, the latest episode of Jay Leno's Garage is actually pretty fascinating. The Ricardo HyBoost is a 2009 Ford Focus that has had a 1.1-liter engine swapped in for the stock 2.0-liter four. That might not get you performance enthusiasts out there fired up, until, that is, you hear that the 1.1L is also fed by both a turbocharger and an electrically driven supercharger for an instant-on "torque-fill" effect. Sounds about right, considering that Ricardo engineering is part of the genius behind the McLaren P1.
Perhaps most exciting of all, the Ricardo folks say that the package should run somewhere in the neighborhood of $1,100. A sort of performance-hybrid that makes sense for the frugal driver and the enthusiast one, then. There's a lot more to the HyBoost, all of which can be seen in the video below.
