Piston Slap: Decomposition of the Fuel Composition Sensor?

Longtime TTAC commentor rrhyne56 writes:

Flex Fuel. I see it more and more. From what I’ve heard, this mainly means the vehicle has a fuel system that alcohol wouldn’t eat up. (Mainly, yes. — SM)

So here’s my question: do the more recent models of these vehicles have the ability to sense what level of alcohol is in the fuel lines and adjust the engine accordingly, to make best advantage of whatever current gasoline/alcohol or alcohol/gasoline mixture is entering the engine? I watched a build on Mighty Car Mods where the Haltech engineer was tweaking just such a system.

I know, I know, I ought to just Google it. But I thought it might make for some lively discussion.

Study Says: EV Drivers Coddled, Flex Fuel Cars Discriminated Against

So what is all this talk about flex fuel being shoved down our the throats of our cars, and EVs driving up Xanax sales due to rampant range anxiety? Bloomberg brings us astounding news:

“Public charging stations for electric autos outnumber outlets for alternative motor fuels by almost two to one, even though there are hundreds of times more flex- fuel vehicles than plug-in cars on U.S. roads. “

Take A Chance On E(85)

Meanwhile, Back At The Farm: Ford Promises Flex-Fuel Bumper Crop

As TTAC readers well know: There is a huge E85 flex-fuel loophole in the new federal fuel economy CAFE standards. Ford will drive right through that barn door-sized hole.

By the end of this year, Ford wants to deliver 370,000 flex fuel vehicles, a number which they can trade against fuel oinkers. Let’s review: A flex-fuel vehicle is one that is capable of running on E-85. But it doesn’t have to. It can also run on straight gas. Or on any mixture of the two fuels. As long as it’s E85 capable, it counts at least for a Peppermint White Chocolate Mocha at the DC CAFE.

  • Philip I love seeing these stories regarding concepts that I have vague memories of from collector magazines, books, etc (usually by the esteemed Richard Langworth who I credit for most of my car history knowledge!!!). On a tangent here, I remember reading Lee Iacocca's autobiography in the late 1980s, and being impressed, though on a second reading, my older and self realized why Henry Ford II must have found him irritating. He took credit for and boasted about everything successful being his alone, and sidestepped anything that was unsuccessful. Although a very interesting about some of the history of the US car industry from the 1950s through the 1980s, one needs to remind oneself of the subjective recounting in this book. Iacocca mentioned Henry II's motto "Never complain; never explain" which is basically the M.O. of the Royal Family, so few heard his side of the story. I first began to question Iacocca's rationale when he calls himself "The Father of the Mustang". He even said how so many people have taken credit for the Mustang that he would hate to be seen in public with the mother. To me, much of the Mustang's success needs to be credited to the DESIGNER Joe Oros. If the car did not have that iconic appearance, it wouldn't have become an icon. Of course accounting (making it affordable), marketing (identifying and understanding the car's market) and engineering (building a car from a Falcon base to meet the cost and marketing goals) were also instrumental, as well as Iacocca's leadership....but truth be told, I don't give him much credit at all. If he did it all, it would have looked as dowdy as a 1980s K-car. He simply did not grasp car style and design like a Bill Mitchell or John Delorean at GM. Hell, in the same book he claims credit for the Brougham era four-door Thunderbird with landau bars (ugh) and putting a "Rolls-Royce grille" on the Continental Mark III. Interesting ideas, but made the cars look chintzy, old-fashioned and pretentious. Dean Martin found them cool as "Matt Helm" in the late 1960s, but he was already well into middle age by then. It's hard not to laugh at these cartoon vehicles.
  • Dwford The real crime is not bringing this EV to the US (along with the Jeep Avenger EV)
  • Kwik_Shift_Pro4X Another Hyunkia'sis? 🙈
  • SCE to AUX "Hyundai told us that perhaps he or she is a performance enthusiast who is EV hesitant."I'm not so sure. If you're 'EV hesitant', you're not going to jump into a $66k performance car for your first EV experience, especially with its compromised range. Unless this car is purchased as a weekend toy, which perhaps Hyundai is describing.Quite the opposite, I think this car is for a 2nd-time EV buyer (like me*) who understands what they're getting into. Even the Model 3 Performance is a less overt track star.*But since I have no interest in owning a performance car, this one wouldn't be for me. A heavily-discounted standard Ioniq 5 (or 6) would be fine.Tim - When you say the car is longer and wider, is that achieved with cladding changes, or metal (like the Raptor)?
  • JMII I doubt Hyundai would spend the development costs without having some idea of a target buyer.As an occasional track rat myself I can't imagine such a buyer exists. Nearly $70k nets you a really good track toy especially on the used market. This seems like a bunch of gimmicks applied to a decent hot hatch EV that isn't going to impression anyone given its badge. Normally I'd cheer such a thing but it seems silly. Its almost like they made this just for fun. That is awesome and I appreciate it but given the small niche I gotta think the development time, money and effort should have been focused elsewhere. Something more mainstream? Or is this Hyundai's attempt at some kind of halo sports car?Also seems Hyundai never reviles sales targets so its hard to judge successful products in their line up. I wonder how brutal depreciation will be on these things. In two years at $40k this would a total hoot.So no active dampers on this model?
