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.

10 most memorable cars and SUVs of 2019

It's no surprise that a car reviewer will drive a large number of cars over the course of a year. Indeed, when the clock strikes midnight on Dec 31, I will have driven 75 new cars, trucks and SUV this year (and one old Peugeot) over the course of weekly evaluation loans and first drive events. That sure seems like a lot. Some definitely got more attention than others, and some came and went without leaving much of an impression – I completely forgot I drove a Kia Forte. Yet in the spirit of this day, I thought I'd pick the 10 that I would love to see under the Christmas tree tomorrow morning. You know, just in case you were looking to get me something. I'll also throw in a couple disappointments that were memorable for the wrong reasons. They'd get sent back to the store on Boxing Day. Lexus LC 500 Pictured below and resplendent in its Flare Yellow metallic paint, the car that would reach highest on my list is the divine Lexus LC 500. As a devout lover of GT cars, the LC ticks all the boxes. Muscular and characterful engine? V8, check. Beautifully made and memorable interior? It's gorgeous, to hell with Remote Touch. Check. Comfortable and reasonably practical? Superb seats and, uh, yeah. Makes me want to stand there and stare at it? You bet. Though I long figured my heart would say LC but my head "Porsche 911," after this go-around, that's no longer the case. LC, pretty please. 2020-lexus-lc500-f34-2 View 19 Photos Polestar 1 I actually feel lucky that I got to drive the Polestar 1. Only 150 will be produced each year, and it's a far more special thing than it would initially appear. And that's despite initially appearing to be a beautiful, classic two-door GT car with a roof so rakish it's only possible because it's made of carbon fiber. That itÂ’s a massively powerful plug-in hybrid with more all-electric range than any other PHEV is a thick dollop of whipped cream on a slice of Toscakaka. You know, Swedish dessert, Swedish car. Fine, I'll stick to Ikea references.  Polestar1_Launch_SanFrancisco-0014 View 44 Photos Volvo V60 Cross Country Speaking of Sweden, did I drive this car off the road there? Sure did! And despite this, the V60 Cross Country scratches that certain wagon itch and looks sensational to boot. I wish it were available with the T8 plug-in hybrid powertrain, but it's best not to get greedy at Christmas.

2016 Ford Explorer order guide revealed

The configurator for the refreshed 2016 Ford Explorer is already up and running. However, if you're the type of person that really likes to dig into the nitty-gritty of a vehicle's features, then the order guide for this latest Ford is now available (pictured right). While the documents don't list fuel economy, engine power or pricing, they give a precise idea of all of the differences separating each of the five trim levels: Base, XLT, Limited, Sport and Platinum. In addition to the tweaked styling across the board, even the Base model now features a rearview camera with a washer. There are also three new colors available: Shadow Black, Blue Jeans Metallic and Guard Metallic. Base, XLT and Limited trims are available with either a 3.5-liter V6 or new, optional 2.3-liter EcoBoost four-cylinder. All of them are mated to a six-speed automatic, and all-wheel drive is optional with either engine. The new Platinum trim basically loads the Explorer up with everything imaginable. Power comes from the 3.5-liter EcoBoost V6, matched with all-wheel drive. Plus, the Platinum trim gets standard luxuries like a dual-pane moonroof, adaptive cruise control, a premium sound system and Ford's super-soft Nirvana Leather covering the seats. There are also some new tech features throughout the rest of the lineup. For example, an updated auto-parking system is also available on the Limited but comes standard on the Platinum. Furthermore, a 180-degree front camera and second-row USB charging are optional on the Sport but are standard on the Limited and Platinum. Check out the gallery for even more of the changes.
