Sixt rental cars in France hasn’t been doing manual transmission cars for years - automatics get better gas mileage and are actually better on overall emissions

Sixt rental cars in France hasn’t been doing manual transmission cars for years - automatics get better gas mileage and are actually better on overall emissions (you’ll notice modern manual cars keep the revs up even when you let off the throttle). Germany has followed, I believe. But you’re right, it’s probably those dumb Americans’ fault.

  I think they are referring to rev hang that occurs in newer manual transmissions where the ECU is tuned to not drop revs quickly for emissions reasons. This makes for an annoying 1st-to-2nd gear shift because the driver must wait a long time between shifts before engaging the clutch in order to shift smoothly. Mostly only newer MTs do this - some worse than others.

    That's fascinating. I had a manual hire car this summer and I kept getting the 1st - 2nd shift wrong and juddering - I was wondering why I suddenly couldn't shift well (I've exclusively driven manuals for years, so it wasn't as straightforward as being out of practice). I wonder if that was why.

    yes i was referring to rev hang and you're spot on. for anyone else seeing this that is interested, here is a video: https://www.youtube.com/watch?v=mm6SSeLivqE https://www.youtube.com/watch?v=mm6SSeLivqE

Strangely I keep getting manuals, with automatics being additional money on the table.

I didn't say it was their fault. I just said they're ignorant and lazy... which stands. I drive amongst them every day, and have for decades. I didn't notice this auto-revving behavior, however. I was driving a Ford in England, so maybe they don't have this "feature."
