Ford, Ram in heavy-duty towing spat

Every pickup truck commercial has the brand trying to convince us that its model is the biggest, brawniest vehicle on the block. But Ford and Ram appear ready to really throw down the gauntlet and scrap over the towing figures for their heavy-duty models, and it could potentially end up in court.
The issue revolves around what it means to be best in class. Ford claims that its 2015 F-450 (pictured above) has a max tow rating of 31,200 pounds, compared to 30,000 pounds for the Ram 3500 (right). However, both companies market these heavy haulers as having the top towing in their class. According to Automotive News, Ford is threatening legal action if Ram doesn't back down.
The situation isn't as simple as just comparing the numbers, though. First, the two companies calculate their towing capacities differently. Ram adheres to the SAE J2807 rating, while Ford uses its own internal system. Although, as the company introduces new models, they are certified using the SAE standard. "When an all-new F-Series Super Duty is introduced, it also will use SAE J2807," said Ford to Autoblog in an emailed statement.

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.

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.
