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.

We compare 2021 Ford Bronco and Bronco Sport specifications to their ritzy Land Rover competiton

The 2021 Bronco and Bronco Sport are the spearheads for Ford's new 4x4 sub-brand, with the former taking the fight directly to the Jeep Wrangler and the latter providing Ford with a more rugged alternative to the Escape. We've already looked at how the new Bronco and Bronco Sport compare to their mainstream competition, but we'd like to see how the Bronco stacks up to another hotly anticipated returning nameplate: the Land Rover Defender.  Not to leave its little sibling in the cold, I decided to browse Land Rover's lineup and see what might be a suitable counterpoint to the Bronco Sport. For better or worse, I found an almost-perfect fit in the Range Rover Evoque. So, how do these new American 4x4s compare to the Old Country's more-expensive alternatives? Let's dig in, starting with the big boys.  As you might expect from the Bronco's robust credentials, it holds its own here against the more-expensive Brit. The Defender's higher price point brings along a good bit of power advantage with both engines, but that's to be expected. The Defender also has that trick adjustable-height suspension that the Bronco lacks, giving it an edge in practicality, and it can also tow quite a bit more.  On the flip side, there are quite a few advantages to going with the Ford, including a greater number of choices in terms of powertrain. The available manual transmission on four-cylinder Broncos is a nice bonus, for instance, as is the option of getting either the base 2.3-liter or the optional 2.7-liter engine with either wheelbase. The Defender is a bit more restrictive in this regard offering only the inline-six on the short-wheelbase model. As an added bonus, the Bronco is a convertible. That may not necessarily be a "plus" for all shoppers, but it's certainly an added bit of versatility (and potential appeal) the Defender lacks. And of course, the Bronco can be had for as little as $30,000, whereas the Land Rover starts at $50,000. Now, on to the less-rugged siblings. The specs here are actually a little tighter in most respects, but the powertrain story is almost identical. The Evoque checks in where the Bronco Sport tops out, and the Range Rover gets an optional high-output variant of the 2.0-liter turbocharged four.

Ford pranks unsuspecting blind dates with Mustang GT and stunt driver

There's 'speed dating,' that ludicrous get-to-know-you ritual devised by The Inquisition of Mating, and then there's 'dating at ludicrous speed,' which is a better description of what Ford has done in this latest video for the 2015 Mustang GT for your Valentine's Day enjoyment. The Blue Oval used a professional stunt driver to hook six guys into going on a little car trip, but the setup is the key – she pretends she's not that good at driving, until she's really good at it. You can check it out above. Kudos to the guy who goes from "You might want to shift again" to "That's what I'm talking about!" without any question. And the ninja.
