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.

2015 Ford F-150 to get 2.7-liter EcoBoost?

As we prepare for the arrival of the all-new, next-generation Ford F-150, rumors about the new truck are picking up steam. Naturally, many of said rumors aren't just related to the way the truck will look (it's expected to take design cues from the Atlas concept shown above), they're tied to what's going to motivate the Blue Oval mainstay, with Ford's EcoBoost range likely to play an increasingly key role. While we're still expecting the current 3.5-liter, twin-turbocharged V6 to retain its position as a premium alternative to Ford's naturally aspirated V6 and V8, a Canadian automotive news site is proposing that the Dearborn automaker is also preparing a new, more fuel-efficient downsized EcoBoost option.
Autos.ca is reporting that a new, 2.7-liter, twin-turbocharged V6 could find its way into the lighter, aluminum-intensive truck. The new engine supposedly makes use of asymmetrical turbos to generate 320 horsepower and 370 pound-feet of torque - substantially more impressive numbers than the current 3.7-liter base engine's 302 ponies and 278 lb-ft - while offering improved fuel economy and emissions. The new 2.7 EcoBoost (internally dubbed "Nano") isn't expected to supplant the naturally aspirated V6 as the F-150's base engine, it's expected to slot in above directly it.
Naturally, we're prescribing more than a few grains of salt to go with these rumors, at least until Ford debuts the next F-150 at the 2014 Detroit Auto Show, a reveal we'll be covering in a mere two weeks.

2016 Ford Focus RS mule spotted on US soil

Okay Ford, this is what we like to see. One of our intrepid spy photographers has captured a vehicle that we weren't even sure would see the light of day - the next Focus RS. While this is pretty clearly a mule based on the current Focus ST, as our spy points out, there are a number of giveaways about this hot hatch's true nature.
Indication number one that all is not right with this Focus is the heavily camo'd front fascia, which has been completely reconfigured for duty on the RS. It boasts significantly larger grilles that are meant to accommodate what is likely the 2.3-liter, turbocharged four-cylinder that's destined for the 2015 Ford Mustang. Considering that, then, we can expect around 300 horsepower and 300 pound-feet of torque from the hottest of Foci, although it's entirely possible that the production model could climb even higher, to around 330 hp.
The front fascia tweaks are complemented in the back by a modified rear bumper, which fails at hiding a pair of exhaust tips quite unlike the standard Focus ST's center-exit exhaust. Other obvious changes include the wheel/tire/brake package on this particular car. Larger 19-inch wheels are shod in super-sticky Michelin Pilot Super Sport tires in 235/35/19 while the brakes feature what we think are four-piston calipers, possibly from Brembo, up front.
