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 S-Max Concept proves minivans aren't always minivans [w/video]

Ford's latest don't-call-it-a-minivan is called the S-Max Concept, and it's a looker. As you can see, the conceptual overgrown hatch makes good use of Ford's latest design language, especially at the very front of the S-Max, which bears a striking resemblance to production models that include the Focus, C-Max and Fusion.
Powering the S-Max Concept is a 1.5-liter EcoBoost engine, and while Ford doesn't actually list power figures for the concept, previous estimates put the mill at 133 kW of power (about 178 horsepower) and 240 Nm of torque (about 177 pound-feet). Inside, there's room for seven passengers and at least some of their luggage.
As you'd expect, the S-Max is loaded up with all of Ford's latest infotainment technology, including Sync and MyFordTouch. More interestingly, there are also onboard heart and blood glucose monitors that we doubt will be seeing the light of production anytime soon. On that topic, don't expect to see any S-Max-shaped vehicles hitting the US market from Ford, either.

Ford sticking with manuals for RS models

Traditional stick-shift gearboxes may be losing ground quickly to dual-clutch transmissions, but Ford knows what hot hatch enthusiasts want. That's why it's sticking with manual transmissions on its RS models for the foreseeable future. The Blue Oval automaker caught our attention yesterday when it revealed the new Focus RS, packing an upgraded version of the turbo four from the Mustang, a trick new all-wheel-drive system and an old-school six-speed manual. After speaking to Ford's product chief Raj Nair at the hot hatch's launch, Autocar reports that the six-speed is here to stay. "All our current research says that customers really like these kinds of cars to have a manual gearbox," Nair told the British publication. "We'll keep looking at market trends, and of course we'll give customers what they want, but for now the manual stays." Autocar further suggests that the same principle will apply to any further Rallye Sport models, so if and when a Fiesta RS rolls around, it's likely it will stick with a stick as well. Although the less potent Focus ST is offered in diesel and wagon forms overseas, wherever it's sold and in whatever form, the six-speed stays a constant in that model as well, just as it does in the smaller Fiesta ST. That doesn't mean that other Ford Performance models won't go without a clutch pedal, though. The new GT employs a seven-speed dual-clutch gearbox and the new F-150 Raptor channels its muscle through a ten-speed automatic. But as far as Ford's hot hatches go, it looks like the manual will remain alive and well.
