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.

Radical RXC is a Mustang-hearted racecar for the road

Radical has been building fantastic open-cockpit racers and roadcars for years, for the track day enthusiast who wants a vehicle that looks like it could show up for a start at the 24 Hours of Le Mans. The company's latest creation is the RXC, and while this coupe looks like a prototype racer, it's road legal in the UK and in some parts of the US. When testing a car this, um, radical, the first thought is likely to get it to the track for some big slides and wide open acceleration, but XCar Films takes the opposite approach in its latest video to learn how this racer fares on public roads. The version tested here is the standard RXC with the 3.7-liter V6 out of the Ford Mustang tuned to 350 horsepower with a seven-speed sequential gearbox; but Radical also offers the same engine with 380-hp, a 454-hp Ford EcoBoost 3.5-liter twin-turbo V6, or even a 500-hp V8. Even in the most basic guise, it's a handful to control in the wet, if this video is any indication. The cliche of a road-legal racecar is bandied around a lot in the motoring world, but it truly applies to the RXC. The only problem with seeing the RXC exclusively on the road is that it can never really open up and show its full potential. This racer is indeed chomping at the bit to rocket off into the horizon, but all those pesky road safety laws hold it back. Still, the video is a chance to get a better impression about this thoroughbred sports car. Scroll down to check it out. This content is hosted by a third party.

Ford Focus 1.0-liter Ecoboost to only get manual trans in US

Photos of the 2015 Ford Focus leaked earlier today, but now we're able to tell you more details of the global five-door hatchback. Bucking automaker's troubling trend of ditching manual transmissions in favor of automatics, Ford says the new 1.0-liter EcoBoost engine will come only in a six-speed manual in the US, because, well, American drivers aren't as sophisticated as our European brothers and sisters.
Ford didn't come out and say it that way, but it has found American drivers are more prone to complain about automatics in smaller-engine cars, Raj Nair, Ford's group vice president of global product development, said at a press conference last week. The recent JD Power Vehicle Dependability Study backs up Ford's claims, pointing out that drivers are complaining about rough transmission shifts, engine hesitation and lack of power, particularly in small cars. In Europe and other parts of the world, drivers seem to understand the quirks of these pint-sized engines, Nair said, so they'll have the option to buy an automatic. Ford is working on tuning its dual-clutch transmissions to make them more amenable to American driver's tastes.
Ford will show off the refreshed 2015 Focus at the Geneva Motor Show in early March. The car is due for an update, having been on sale in its current form since 2012. The automaker said it is jamming the car full of new technology - like a USB port that promises to charge your phone in half the time as a regular USB port. Features like Sync and a rear back-up camera will come standard. For a more in-depth look at the car, take a look at the full press release.
