Sunday Drive: Big debuts from the Big Apple dominated the headlines

New York Auto Show week has come and gone, and, not surprisingly, the week's biggest bits of news came from the halls of the Jacob K. Javits Convention Center in NYC. Our favorite debut from New York was the Lincoln Aviator, a sharp-dresses crossover that looks lovely inside and out, and sits on underpinnings at least partly derived from the Ford Mustang. While the Aviator may have caught our attention, it wasn't the most popular vehicle debut from New York, at least when judging by the number of page views here on Autoblog. That distinction goes to the 2019 Toyota RAV4, and we're hardly surprised. The RAV4 is the most popular compact crossover in America (in fact it's the most popular vehicle that isn't a pickup truck), and the 2019 version looks like a radical departure from the model that came before. We can't wait to drive the thing. Midsize sedans may not be the darling of the family car set, that honor taken over by the aforementioned crossover, but they still sell in large enough numbers that a brand-new model catches our attention. Such is the case with the 2019 Nissan Altima. We broke down the specs of the Altima and compared Nissan's bread-and-butter sedan with its biggest rivals. And finally, we got some official figures for the 2019 Ford Mustang Bullitt. It'll cost a cool $12,000 over the cost of a Mustang GT, and will benefit from a 480-horsepower, 420-pound-foot version of Ford's excellent 5.0-liter V8 engine. As always, stay tuned this week for all the latest automotive news that's fit to print. 2018 New York Auto Show Mega Photo Gallery | Start spreading the news 2019 Toyota RAV4 actually looks pretty cool 2019 Nissan Altima vs Honda Accord vs Toyota Camry: How they compare 2019 Mustang Bullitt orders open as Ford reveals price and horsepower Image Credit: Drew Angerer/Getty New York Auto Show Ford Lincoln Nissan Toyota Coupe Crossover SUV Sedan 2018 new york auto show

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.

EPA says fuel economy test for hybrids is accurate

The EPA says it stands behind its fuel economy test for hybrid vehicles following controversy about the testing process after Ford C-Max Hybrid customers and automotive journalists alike struggled to achieve 47 miles per gallon, the advertised mpg number, Automotive News reports. Ford responded to the issue almost two weeks ago by claiming that a 1970s-era EPA general label rule was responsible for the inaccurate mileage numbers, rerating the C-Max Hybrid's mpg numbers and offering customers rebates. Ford later said it didn't overstate the C-Max Hybrid's fuel economy and that it was surprised by the low numbers.
Ford technically didn't do anything wrong because it was following the general label rule, but agency regulator Christopher Grundler says the automaker was exploiting a loophole when it came up with the hybrid C-Max numbers, and that the testing process remains accurate. The general label rule allows vehicles that use the same engine and transmission and are in the same weight class to share fuel economy numbers, but it doesn't take into account other factors such as aerodynamic efficiency, which affects hybrids more drastically than non-hybrid vehicles. Ford originally used the Fusion Hybrid economy figures for the C-Max Hybrid and claimed the engineers didn't realize that its aerodynamic efficiency would affect fuel economy as much as it did.
