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.

Ford Fiesta ST GRC Racecar is hungry for podiums in 2013

As we reported earlier, the Chicago showing of this plucky Ford Fiesta ST GRC racer points to bigger and brighter days for Global RallyCross. For the upcoming season, you can expect to see Ken Block and Tanner Foust both driving the Ford racecar, and if last season's results are any indication, you can anticipate quite a few podium appearances, as well.
The Fiesta seen here was built by the Swedes at OlsbergsMSE, and will be driven in anger by Foust in 2013. Modifications are, as you'd expect, extensive, and include an engine, exhaust and braking upgrades, a racing style short-throw shifter and a limited-slip differential. As you can see, the car has been fully stripped out and caged for maximum speed and safety, too.
Refresh your memories with the details of the car, in the press releases below. And if you head out to the Chicago Auto Show this year, don't forget to drop by the Ford stand to have a look.

2014 Ford F-150 Tremor adds some sport to shake things up

Like most quakes, the 2014 Ford F-150 Tremor caught us by surprise. We weren't expecting Ford to offer up another version of its best-seller so soon before the truck's full redesign, but that's exactly what the company is doing.
While Ford calls the Tremor a "performance truck," the new pickup doesn't play on the same level as the SVT Raptor does on dirt, or even the long-gone SVT Lightning did on pavement. Think of it as a parts bin sport truck that probably does a better job looking the part than acting it. The Tremor utilizes the same twin-turbo, 3.5-liter EcoBoost V6 available across the F-150 lineup, producing 365 horsepower and 420 pound-feet of torque, but matches it with a 4.10 rear axle - the shortest final drive ratio you can get in an F-150 - for the strongest possible acceleration.
The Tremor does do a decent job looking the part. Available only in short-wheelbase, regular cab configuration with your choice of two- or four-wheel drive, it struts around wearing the F-150's FX Appearance Package, flat black accents, 20-inch black wheels, HID headlights and a special exterior graphics package. The Tremor is the only regular cab F-150 with a flow-through center console, which means it also gets a floor-mounted shifter and bucket seats that are covered in black leather with red piping. Some brushed metal accents and steering wheel with red stitching round out the interior upgrades.
