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 exec reveals new F-150 Raptor packs 450 horsepower

Between the new GT supercar, Shelby GT350R muscle car and F-150 Raptor off-roader, Ford had quite the array of performance machinery on display at the Detroit Auto Show earlier this month. One thing it didn't reveal about any of the three, however, is how much power they'd pack, but a senior executive at the Blue Oval automaker has reportedly let the cat out of the bag when it comes to the Raptor. During a televised interview during the Rolex 24 at Daytona this past weekend, Ford's product development chief Raj Nair is said to have revealed that the new F-150 Raptor will offer 450 horsepower. That's pretty impressive from a 3.5-liter turbocharged V6, and would put the new Raptor out ahead of the 411 hp produced by the 6.2-liter naturally aspirated V8 in the previous SVT Raptor. That doesn't give us the whole picture, though, because in a vehicle this big especially, torque will play a huge factor. The outgoing Raptor offered 424 pound-feet of twist, and the existing 3.5-liter EcoBoost engine is already producing 420 lb-ft – so it seems fairly safe to assume the new Raptor will eclipse those figures as well, but we'll have to wait for official word to find out for sure.

VW walks away from Aurora after self-driving startup partners with FCA

BERLIN — Volkswagen has ended its partnership with self-driving car software firm Aurora, two days after the Silicon Valley start-up said it would build autonomous platforms for commercial vehicles with Fiat Chrysler Automobiles. "The activities under our partnership have been concluded," a VW spokesman said in a statement on Tuesday following an earlier Financial Times report on the move which said VW now wanted to work with Ford Motor Co on autonomous driving. Ford's majority-owned subsidiary Argo AI is building an automated "driver" that could compete with Aurora's technology. Aurora said Tuesday "Volkswagen Group has been a wonderful partner to Aurora since the early days of development of the Aurora Driver." The company's statement added that it continues to work "with a growing array of partners." The autonomous vehicle industry is still in its infancy, and alliances and strategies are fluid. Aurora has sought to remain independent and serve a number of would-be autonomous vehicle makers rather than be acquired. Aurora, which said in February it had raised $530 million in new funding, also has partnerships with Hyundai Motor Co and China's Byton to develop and test self-driving systems for automakers, fleet owners and others. After announcing its partnership with Aurora in early 2018, VW last June began discussions with Ford to develop a range of commercial vehicles, later extending the discussions to include electric vehicles and Argo's autonomous driving technology as part of an alliance designed to save billions in costs. VW and Ford have not announced partnerships involving electric or autonomous vehicle technology. Green Chrysler Fiat Ford Volkswagen Technology Emerging Technologies Autonomous Vehicles
