Ford Mustang GT Bi-Fuel CNG

Highly intrigued, we recently visited a Southern California Gas Company office to check out several hybrid vehicles promising something new. Unlike more commonplace gasoline-electric hybrids, we were there to evaluate innovative gasoline-compressed natural gas (CNG) hybrids - yes, they run on unleaded gasoline and compressed natural gas. According to the experts on hand, this arrangement delivers extended range and reduced emissions while chipping in with lower operating costs than pure-gasoline vehicles. There are advantages over its gasoline-electric counterparts, as well.
The program is part of a three-way collaboration between The Carlab, a Southern California-based automotive consulting firm, Landi Renzo USA, a company specializing in alternative fuel solutions, and America's Natural Gas Alliance, a group that promotes CNG. Long story short, the team has engineered a way to allow a modified internal combustion vehicle to seamlessly switch between two fuels (gasoline and CNG) with no driver intervention. In theory, and if it works as well as promised, it's a win-win for the vehicle owner and the environment.
Parked at the Gas Company office were six different gasoline-CNG hybrid vehicles. To demonstrate the technology's versatility (just about any gasoline vehicle may be modified) Carlab brought a varied assortment of bodystyles, each from a different automaker. After taking a quick glance at the half-dozen in the parking lot, we made a beeline for the performance-oriented Ford Mustang GT - a 2012 model - with the six-speed manual gearbox.

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 gets fuel economy bump to 41 mpg

The 2014 Ford Fiesta is in showrooms now with refreshed styling and new performance ST model, but it's what isn't yet available that should help the Fiesta stand out from the growing crowd of subcompacts. Aside from the new 1.0-liter EcoBoost model coming later this year, Ford recently told us that a new Fiesta SFE trim level is on the way that should put the updated Fiesta at the top of its class for fuel economy.
The new Fiesta SFE will hit an estimated 41 miles per gallon on the highway when equipped with the six-speed automatic transmission. The current listing on fueleconomy.gov shows the 2014 Fiesta getting up to 29 mpg city and 39 highway, but the SFE will get minor aero tuning and a recalibrated engine controller to help bump the highway figure past rivals like the Chevrolet Sonic and Nissan Versa - both of which top out at 40-mpg highway. There's still no word as to when the small 1.0-liter EcoBoost will show in the US, but Ford has indicated that engine's fuel economy isn't expected to be released until October.
