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.

Dodge Durango SRT, Ford F-150 Lightning and why we like physical controls | Autoblog Podcast #678

In this episode of the Autoblog Podcast, Editor-in-Chief Greg Migliore is joined by News Editor Joel Stocksdale. They start things off by discussing cars they've been driving, including the 2021 Dodge Durango SRT and the 2021 Toyota Camry Hybrid XSE. Next they discuss the announcement of the Ford F-150 Lightning electric truck, Genesis G70 Shooting Brake and the use of physical controls in cars instead of touchscreens. Finally, they help a reader spend some money.

James May picks 13 most significant cars ever for London Classic Car Show

James May tends to be the most pragmatic of the Top Gear UK hosting crew. Jeremy Clarkson obviously likes his vehicles loud, brash and preferably British, and Richard Hammond seems to have a thing for American muscle. May appears to find joy just in the mechanical nature of things, whether high performance or simply made for getting around. He's getting a chance to put that appreciation on display by curating a 13-car collection at the London Classic Car Show called The Cars That Changed The World. May actually wants to provoke debate from visitors about the exhibit and is separating his choices into two categories: The Halls of Obviousness and The Chambers of Bloody-mindedness. The first bunch includes the usual important vehicles you expect to see, but the other group has the really interesting picks. As May explains these selections in the event announcement, "I believe they are just as significant historically but they've simply been forgotten or misunderstood." The obvious choices are: 1886 Benz Motorwagen 1908 Ford Model T 1938 Volkswagen Beetle 1959 Austin Mini 1964 Ford Mustang 1997 Toyota Prius And the more eccentric ones are: 1901 Waverley Electric 1906 Cadillac Model K 1933 Standard Superior 1972 Honda Civic 1980 Lada Riva 2009 Bruno ExoMars Rover If you notice, there are only 12 vehicles listed above. That's because the final one is being kept secret for show attendees, but May considers it the most significant car ever made. The London Classic Car Show runs at the ExCeL in London's Docklands from January 8-11, 2015. In addition to May's exhibit and the other vehicles there, Formula 1 designer Adrian Newey is also curating a display from his own collection. May is hoping to spur conversations with his choices. Let us know in Comments if you notice any glaring omissions that should be among the 13. Read the full announcement below, along with a brief explanation for each choice from May. GET READY FOR A CLASSIC ARGUMENT 30/12/14 James May has chosen the 13 most significant cars of all time for The London Classic Car Show... but is he right? It's bold, controversial and bound to cause arguments... and that's just the way BBC Top Gear's James May wants it. May has stuck his neck on the line and has chosen what he regards are the 13 most influential cars of all time. The result is The Cars That Changed The World and it's one of the star exhibits at the London Classic Car Show taking place at ExCeL in London's Docklands from 8-11 January 2015.
