Modern automatic trans is more fuel efficient than manual?

Of course. You're not smarter than the computer. Also twenty-year-old automatics are more fuel efficient and faster than modern manuals. Everyone who drives a manual doesn't actually know what the fuck he's doing.

Can you tell me why?

With the same number of gears and ratios, they should be close. There might be differences in friction.

A competent manual driver has better sense of momentum and anticipation.

Automatic drivers often think the cars have two states: step on gas, step on brake.

This site explains better than MS and much gentler and more compassionate than MS.

Not a statistically significant occurrence.

Modern automatics account for this.

Computer controlled autos know drivers are dumb and  mitigate that. Manuals are at the mercy of their dumb drivers.

My VW diesel is rated 30 city/42 highway, for both manual and automatic.

In practice I get on average 65 highway, 45 city. The car shows instantaneous mileage on the display and it also gives advice on when to shift. So you quickly learn what sort of driving ruins the mileage (a lot of speeding up and slowing down, trying to gun it going up hills, etc) and learn to avoid those moves if you want to.

You can still drive more efficiently with automatic and easily get higher than rated but you are not going to hit the level you do with manual control.

The EPA ratings are based on putting the car on a rack and simulating various kinds of normal driving. Normal driving is inefficient driving, but is what the average person does supposedly.

A couple of guys drove across country in this car and managed to get 78mpg on it during the trip. They drove more conservatively than I do.

Hm, I see that the same duo repeated the feat a couple years later in 2015 and got 81.17 mpg on a cross country trip.

Not too shabby.

This happens to me constantly: a guy like Wildriver will be in front of me in a sporty little manual Mazda at a light, the light changes and my big rusty Ford keeps pace through first gear. Then the Mazda guy fucks up shifting into 2nd and loses all power. My slushy four speed AOD doesn't fuck up and I maintain power but I have to brake to keep my 20 year old, sub 200 horsepower behemoth from rolling over his Japanese toy car.

???

No, the computers can't keep drivers from braking too late or too hard and accelerating too quickly.

30+ years ago the conventional wisdom about manuals vs. automatic transmissions was that the automatics always wasted power even in normal driving due to slippage.

Whereas manual transmissions were either engaged, slipping due to driver choice, or disengaged/thrown out; aside from slipping the clutch, no slippage.

Obviously things have changed efficiency-wise.

One of the articles mentioned that some modern automatics have 11 gears or more. I can see how that would outclass manual with 5.

My car has 6. That 6th is very useful for freeway cruising. I could handle 7 gears no problem. 11 gears though, nah.

You can go with CVT which has infinity gears. LOL. It is very efficient but my manual Mazda6 will be long gone past you.

To each his own. I know you greatly value your furious masturbation time so it's important for you to get home.

Me, I drove to Australia and back last year and it only cost 9 cents worth of petrol.

That would've been via the Indian Ocean, with the Forties or Fifties tailwind. No way you'd get that mileage on the Pacific.

These days, many 'automatics' are really 'automated manuals' in the way they operate.

That's how they can make those 'paddle shifts' an option.
