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.

Hennessey completes first VelociRaptor SUV conversion [w/video]

Start with a Ford F-150 SVT Raptor as your base vehicle for modification, and chances are high that you'll end up with something pretty cool. Now, have those modifications done by professional lunatics Hennessey Performance, make the project turning the pickup into an ultra-long SUV, and the result stands a real chance of being a total kick in the ass. Let us present the Hennessey VelociRaptor then, in all of its awesomeness.
Hennessey has taken care in grafting a "Expedition style" rear cabin onto the Raptor, complete with an optional third row. The pictures we have show a cabin that's up to the fit and finish standards of the original Ford truck, too. The cab added over the bed also makes room for a massive load space out back, accessible via split out-folding doors and long enough for a person to lay down in (see video).
Mechanically, the truck-turned-SUV sticks with Ford's stock 6.2-liter V8, rated at 411 horsepower, or can be had with a supercharger and some 600 hp. Hennessey says the stock-motor VelociRaptor will run from 0-60 miles per hour in 7.5 seconds, while the hi-po version takes just 5.9 seconds. The SUV does take some of the off-road ability away from the Raptor, with the company saying it hasn't yet had the opportunity to test its capabilities. On-roading and "moderate off-road duties" are the current prescription.

Ford hybrids getting update to improve fuel economy

Ford has announced that it is introducing "calibration updates designed to improve on-road fuel economy for owners of the 2013 Ford C-Max Hybrid, 2013 Ford Fusion Hybrid and 2013 Lincoln MKZ Hybrid."
We can speculate that these changes are at least due in part to lawsuits over mileage claims of hybrid vehicles. The automaker is enhancing 2013 models starting in August by raising their electric cruising speed to 85 miles per hour from 62 mph, optimizing the use of active grille shutters and the climate control system, shortening the engine warm-up period by 50 percent and reducing electric fan speed to minimize the fan's energy consumption.
It bears mentioning that Ford is doing pretty well in the US electrified vehicle market this year. The company claims to have grown its share in the segment by 12 points to 16 percent while taking a high number of Toyota Prius trade-ins in the process. Conversely, Toyota has experienced a five-percent drop in new-Prius sales over the same period. Additionally, Ford states that it has increased its share of the US vehicle market by one percent this year, more than any full-line automaker.
