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.

Feds open investigation into Chevy Express, Ford Freestar rust issues

'Tis the season... for road salt. And with that, comes rust. And what does rust bring? Well, for Ford and General Motors, a National Highway Traffic Safety Administration investigation. According to The Detroit News, NHTSA is looking into potential recalls issues with Chevrolet Express vans and Ford Freestar minivans.
The feds have received five complaints that rust has caused leaking fuel filler pipes on 2003 Express vans. Separately, seven complaints have been filed over excessive rust in the rear wheel wells of 2004 Ford Freestar and Mercury Monterey minivans. The Freestar and Monterey went out of production in 2007. Neither issue has resulted in any crashes or injuries, according to the report.

Average transaction prices climb to a record $36,270 in January

The automotive sector made a hash of the numbers last month, a mess of pluses and minuses clogging the transaction-price charts according to Kelley Blue Book. The overall industry rose one percent, even though buyers bought fewer cars and light vehicles in January 2018 vs 2017 using the selling-day adjusted rate. Due to January transaction prices rising to $36,270, a record for January, the value of new vehicles sold climbed more than $1 billion compared to January 2017. KBB's transaction prices don't include customer incentives, which changes the complexion slightly; average incentive spending rose to just over ten percent. The average transaction price in December 2017 was $36,756, so January dropped a bit - nothing unexpected, with the month annually blamed for "January doldrums." More revealing is the fact that the average transaction price in January 2017 was $34,910. This year's plumped-up figure came courtesy of the continued shift to crossovers, SUVs, and light trucks, which shouldn't surprise anyone who's read an automotive blog in the past 20 years. That category comprised nearly 70 percent of new vehicle sales for the month. Some manufacturers profited more than others, though. Fiat Chrysler managed 12.8 percent fewer sales in January compared year-on-year, but the company's vehicles sold for $1,300 more. The Ford brand suffered a 6.3-percent dip in sales, but brand transaction prices increased $2,000, while a Lincoln sold for $8,700 more on average. General Motors sold more cars and sold them for more money; overall GM transaction prices rose four percent, or $1,270, while a GMC traded hands for seven-percent more than in January 2017 and a Cadillac got $2,300 more on average. Of KBB's listed automakers, the Volkswagen Group got the most of out its customers, transaction prices rising at the German automaker by 5.6 percent to $42,243 in January 2018 compared to a year earlier. American Honda followed with a 4.3-percent increase to $28,991, GM in third at 4.1 percent to $40,313. Find your next car at Autoblog using our new and used car listings or the Car Finder tool. Broken out by segment, minivans rocked the table, transaction prices leaping by 7.9 percent to $35,380 compared to January a year earlier. Luxury cars boasted the next-highest rise, at 3.6 percent to $58,533.
