Is anyone hypermiling a VW with 1.4 turbo and 8AT?

    I think that this engine/trans combo could be pretty good , especially if it has
    a stop/start system. It's unclear ( from vw.com) if they actually have it , cuz VW seems to be embarrassed
    about it. I think they do.
    Any opinions , or even better , experience ?

    The 1.4t seems to have gone away for 2022. I see only the 1.5t under current production.
    The 1.4t was used in lots of Bunny Wabbits and the Jetta variant (Bunny with a twunk) seems to have the best numbers with that engine.

    Auto(S8) 29 39 33 / 37.8 57.7 44.7443
    Manual(M6) 30 41 34 / 37.1 58.6 44.4366

    The current Corolla, Civic, and Elantra/Forte all beat those numbers. The six speed manual, though, is very interesting in that it exists and seemed to be available for a while in dealer inventory. And... To see higher EPA numbers on a manual is a rare sight. The raw dyno of 59 highway makes me think a seasoned CleanMPG'er could get into the 70mpg range on a level road.

    The 1.5T seems to be good , also. I was thinking about buying
    a Golf , but it would need to be used cuz they quit selling it here in,
    I don't know , 2020.
    To get 70 MPG in the Prius , I'd have to have level roads , and
    speeds no higher than 40-45 MPh.
    Thanks, Chris.

    The EPA numbers strongly suggest gearing for the open road, and it's those higher speeds where the Prius is out of its element

    2022 Jetta 1.5t numbers:
    Jetta 1.5 4 Manual(M6) 29 43 34 / 37.9 62.8 46.1308
    Jetta SE/SEL 1.5 4 Auto(S8) 29 40 33 / 38.2935 59.8 45.6875

    So manual still shows as available in the basic trim, and the 1.5t with 6MT shows 29/43 on the sticker. Actual dyno numbers are 37.9 and 62.8 on FTP75 and HWFET. The dyno numbers suggest that this would be a great road trip car.
    The Golf is still here but only as the GTI. GTI: Gas, Tires, Insurance - burns through all three at a rate that costs thousands a year for each.

    We know that the GTI is a Golf , but VW doesn't want to call it a Golf.
    The GTI is probably a wonderful hooligan car. but my hooligan days are far
    behind me.
    I really enjoyed my manual cars , but these days I want a car with start/stop.
    Otherwise I KNOW I will be manually shutting down the engine at every other traffic signal.

    And I like hatchbacks. The Jetta ain't one.

    Sad that the Jetta wagon - later renamed Golf wagon - was lost. That's the ultimate hatchback.
    The automatic in these VWs is a light duty Aisin (Toyota) 8 speed, and it tends to last a while. And with HWFET results around 60, I'd guess it's programmed rather well.

    Yeah , that's my take on it. I want to learn more about it.
    By driving one , of course.

    I've been seeing more cars with the 48V stop/start system. Pretty cool. It even adds a small amount of torque accelerating from a stop.

    In the Prius , that takes load off the ICE and allows one to accelerate at 25MPG.
    My friend Mary Beth has a 2020 Mini Cooper ssith start/stop. She disabled it a few days after she bought it. Shrugs.

    And when I say "accelerate" I mean "gather speed in a leisurely fashion".
