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.

2022 New York Auto Show Roundup | All the reveals, reviews, pictures

NEW YORK — In case you missed it, the New York Auto Show took place this year after being canceled in both 2020 and 2021 due to Covid. A lot of manufacturers showed up in force, but not everybody did. No matter, we were there, and we brought you news, photos and scoops from the floor throughout the show. All of our New York-related stories can be found at our central hub here, but if youÂ’d rather just get a small taste of everything in a quick and digestible format, keep scrolling. 2023 Kia Telluride and its new X-Pro trim Kia revealed the TellurideÂ’s first major refresh at New York, and it makes the three-row crossover a little bit more desirable without screwing up what we liked about it before. ThereÂ’s a new X-Line and X-Pro trim for someone who might want a little more off-road capability, and a number of tech improvements. Most notably, a newly-designed dash features new and bigger screens. 2023 Hyundai Palisade The TellurideÂ’s sister car from Hyundai was treated to a similar refresh. Like the Telluride, Hyundai gave the Palisade a slightly revised look, a new off-road trim (called XRT in the PalisadeÂ’s case), more tech inside and a new dash design with full-width air vents. If we had to choose, weÂ’re a little more impressed with the TellurideÂ’s refresh, as a number of us on staff actually prefer the pre-refresh Palisade styling over the new one. 2023 Jeep Wagoneer L and Grand Wagoneer L This one was inevitable. Jeep revealed the longer, roomier versions of its Wagoneer and Grand Wagoneer in New York, and theyÂ’re designated with an “L” at the end of their names. Total length grows by a foot, and the wheelbase goes up by 7 inches versus the standard Wagoneer models. Jeep has essentially allocated all this extra room to the cargo area, as it now offers a staggering 44.2 cubic-feet of space behind the third row. Besides the L, Jeep announced that its new Hurricane inline-six engine would find its first home in the Wagoneer. Efficiency gets a small boost, and power is more than sufficient at either 420 horsepower (standard output) or 510 horsepower (high-output version) from the twin-turbo I-6. Chrysler Airflow Graphite Concept The Stellantis party continues with Chrysler and its slightly revised Airflow. Re-styled for the New York market after initially debuting at CES in Las Vegas, the Airflow Concept gets new paint, changed accent colors, a slightly changed interior design and a new interpretation of the Chrysler logo.

Lower gas prices mean there are excellent deals on green cars right now

The phenomenon was big enough to make news in 2006, then in 2008, in 2011, in 2012, in 2013, and again last year: a big move in gas prices means a big move in alternative-fuel-vehicle sales. True Car's TrueSavings report, which averages transaction prices across the country to figure out what people are paying compared to MSRP, shows that electric cars and hybrids are ripe for excellent savings right now. The Ford Focus Electric presents the greatest disparity, with the average transaction price of $25,168 representing a 16.1-percent saving off its $29,995 MSRP. The Kia Optima Hybrid and Toyota Prius also snagged spots in the top five, with the Kia offering a 10.7-percent discount and the Toyota a 10.1-percent discount. One hybrid managed to show up among the top five lease offers, too: the Lincoln MKZ Hybrid is just $315 a month for 36 months after $3,875 down in some markets. Alt-energy vehicles got bumped out of the top five finance deals, however. That was dominated by light trucks and, oddly, two subcompacts. The press release below has more details. TrueCar finds hybrids, EVs top list of best savings in January Gasoline price plunge = savings for consumers on alternative fuel vehicles SANTA MONICA, Calif., Jan. 15, 2015 /PRNewswire/ -- Ford's Focus Electric hatchback, which sells at an average of 16 percent off MSRP, tops January's list of best savings on new vehicles, according to TrueCar, Inc. (NASDAQ: TRUE), the negotiation-free car buying and selling platform. The "TrueSavings" monthly report analyzes current transaction prices and identifies opportunities for consumer savings. "Fuel savings are not top of mind to many consumers right now, and that makes this a great time to buy a hybrid or electric vehicle," said John Krafcik, president of TrueCar. "With gasoline prices now averaging just $2.10 per gallon, and vehicle preferences tied so closely to short-term gasoline prices, automakers are heavily discounting their most fuel-efficient cars to clear inventories." Toyota's Prius, the world's best-selling alternative fuel vehicle for more than a decade, also makes January's list of best savings. Customers who purchase a Prius Two model this month can save 10 percent off the hybrid car's $25,025 MSRP. "Gasoline prices and vehicle type preferences are strongly related, and this relationship is cyclical in nature," said Krafcik.
