Ford EcoBoost Vehicles Could Get Enhanced Engine Sounds

Ford Motor Company has filed a patent for a sound modification apparatus for turbocharged engines that could be used in future Ford EcoBoost powered models, Ford Authority has learned.

The patent was filed on April 28th, 2022, published on November 2nd, 2023, and assigned serial number 0349317.

Ford Patent Sound Modification Apparatus For Turbocharged Engines

The Ford Authority Take

When the 2021 Ford F-150 Raptor debuted, it did so with a lot of new features, but one of the more interesting was a “trombone” loop present on the exhaust system, which is designed to make the truck’s twin turbocharged 3.5L V6 EcoBoost engine sound more like a V8. It’s clear that FoMoCo is hearing the complaints of those that simply prefer the way a V8 sounds over a four- or six-cylinder engine, as well as the fact that folks who buy performance vehicles also want to hear those engines inside the cabin. Now, this newly filed patent explores additional ways to do precisely that in regards to the Ford EcoBoost family of engines.

Ford Patent Sound Modification Apparatus For Turbocharged Engines

Many modern day turbocharged engines come equipped with an electronic blow-off valve that tends to be pretty quiet, which is precisely why some enthusiasts replace those items with aftermarket parts that enhance a rather substantial “whoosh” type noise generated by the turbos. However, as Ford notes, most solutions are typically inferior to the old style pressure-driven external blow-off valve that’s generally utilized in aftermarket turbo upgrades.

As such, this system aims to somewhat mimic that sound by using an apparatus with a recirculation hose that’s disconnected from the system, while a short piece of hose is mated to the blow-off valve. Additionally, the system would incorporate a “horn” attachment at one end that adjusts the sound and volume of the engine, which could prove appealing to those that enjoy hearing their turbos working under the hood.

    NOBODY wants to hear a V6. Drop a V8 in there.

  2. The Wizard

    Just take the muffler off.
    You’ll have plenty of noise then…

    1. wright

      Then it sounds like an overzealous bumblebee. Laughing every time i hear one. What a joke.

  3. CrabbyMilton

    I guess some people want it loud while some of us want it quiet. I know I know we all liked to put cardboard next to the spokes on our bikes to make it sound like an engine.
    Diesel locomotives and jet engines sound different than decades ago but it’s how it propels the vehicle is what counts no longer the number of cylinders. I don’t deny that V8’s have a special sound but nostalgia and sentimentality is only good for the sake of such. Some people love the sound of a straight 6 so to each their own with this option.
    FORD is having enough trouble so I really wonder why they are wasting time with this high school mentality indulgement.

    1. Stewart Taylor

      Agree, it’s same as the twits spending money installing Borla fake exhaust on E Mustangs. If you buy an electric vehicle you should expect it to be quiet if you want teenager noise buy a v8 gasser, what morons!

  4. Dennis

    If you love the sound of a 4cyl then buy a Subaru or a Honda Civic and put a big can oh the tail of it!
    The V-8 has a beautiful sound. Even Bill Ford said that the throaty V-8 is wonderful.
    If I spend between $50 and $70K on a sportscar or truck, it should sound good! I wouldn’t expect a Ford Escape to sound good, just be quiet with decent performance.
    The new Dodge in-line six that replaces the HEMI sounds like a cow giving birth…not for me!

  5. Rob A

    NOTHING sounds as good as a V-8! Not V10’s, not V12’s, not straight 6’s, etc.
    And while we’re at it, a supercharger sounds better than turbos and kicks in immediately like an electric motor.

  6. CrabbyMilton

    There were many who thought the FORD V10 had a weird sound. To me it sounded like a 6 cylinder engine. But it was smooth as glass. Full disclosure. I had a 2004 MERCURY GRAND MARQUIS from new until November of ’21. I bought a ’21 NISSAN ALTIMA. I loved the 4.6L V8 and I knew someday I would have to replace it and dreaded the idea of a 4 banger. 4’s used to be rough and loud but I was very pleasantly surprised of how smooth and quiet that 2.5L 4 is. I was rear ended on the freeway late last year so without hesitation, I bought a ’23 ALTIMA since I really like that car. So while there is no question in the love of the sound of a V8, it’s not the end of the world if they evetually disappear completely.

  7. David Dickinson II

    The sound is the only complaint I have about my V6 EcoBoost engine. It sounds “tinny,” and I don’t like it. I would prefer a naturally aspirated V-8 but, if that isn’t going to happen, I think Ford is wise to work on improving the acoustics. The acoustics are part of the driving experience, and a deeper growl would be welcome.

  8. Evsrjunk

    Enhance the cylinder count. That will fix the problem.

  9. Todd B

    When you went to dealership you had a choice between the V8or V6 don’t act like you didn’t.

    1. David Dickinson II

      True for pickups, but some models like the Expedition only have a V-6.

      1. wright

        The exact reason my wife will not be getting another Expedition, even though it was been one of the best vehicles we have owned. No V-8, no own. Come on ford, at least a baby 5.0 or even better, the Godzilla.

  10. cj

    i hope they will soon offer the 7.3 pushrod v8 likes in F 250….

  11. John

    Just drop a V8 in that’ll fix the problem

  12. carl

    We have a 2021 Mustang Mach 1 with the active exhaust. Now that gives the sound that you like to hear at that moment. I have it set at Quiet when it starts and does not scare the neighbor across the street. Quiet is a quieter sound than my wife’s ’06 Mustang GT. Then there is Normal which is like the ’06 GT.
    Next is Sport that I use a lot on the street when I get away for our house.
    Lastly there is Track.
    Guess what, none sound like a V-6 or 4cyl.
    And with 5.0L, 480 HP, it has a beautiful sound in all 4 modes.

  13. Altivo Overo

    Sorry. This is a disgusting idea. We have far too much noise pollution already. We should be reducing engine noise, NOT increasing it.

  14. Crabbymilton

    I guess I have to walk some of this back and really pull one out. I always got a kick out of those 1962-1987 CHRYSLER gear reduction starters the way they sounded. I’m sure that could be done.

  15. Joseph Schelling

    Great idea.. can you get aftermarket ? Really a lower rumble be available on a 2022 Bronco Sport.
