Modern autos including CVT and DCTs simply have much broader range of gears than an average 6-speed. The slush-box auto in our Atlas has 8 speeds...many have 9 or 10. It's just math effectively that they will be more efficient...not a flawed test.If they remove the option you just swap one in.
My 82 diesel suburban had a 5sp stick which gave near a 30mpg experience, well worth it
Modern automatic Xmsn cars scoring better on the EPA test is due to the test being flawed.
The lack of demand is self fulfilling in this country because it can cost millions extra on government crash and certification to offer multiple drivetrains .
I started with automatics but can’t own one anymore, they are too unreliable and offer poor economy. The only exception I would make would be hybrid or EV.
"they are too unreliable and offer poor economy" - can you back that up? Take my '13 Focus. Two transmissions...6-spd DCT and a 5-spd manual (what I have). DCT beats it be 1 mph overall. This isn't made up. Unreliable? Modern autos are plenty durable. I don't disagree however that a basic manual is very durable and inexpensive to maintain with the biggest cost a new clutch if you own it long enough vs. a very expensive auto rebuild/replacement but most folks arne't keeping vehicles long enough to care.
