Automatic or manual transmission

Hi everyone,
I just bought a 2010 Yaris, and decided to go with the automatic transmission, but now think I might regret that decision. The salesperson said fuel efficiency between the manual and automatic was nill, and for that reason, I opted not to go with the manual. But I keep reading that the manual offers better real world fuel efficiency.
The only reason I've driven manuals in the past was because of their better gas mileage, but the salesperson said that trend was a thing of the past and he recommended the automatic.
This is my first post on the forum, and am curious what Yaris drivers have learned about this topic while driving their Yaris. Do manuals offer better gas mileage?
Any tips on how I can maximize my fuel economy?
Thank you.

The manual transmission has a slight edge over the automatic in terms of fuel efficiency. Not by any earth shattering amount though. A lot will depend on how you drive it. The M/T lends itself to achieve better results with hyper-mile techniques than the A/T will.

Except I tend to drive my yaris like a hot little go-kart because of the M/T so my milage suffers a little. :)

I drive an AT and have seen average efficiency per tank range from 32 to 41 MPG. I definitely have control over which way it goes, based on my driving style during the tank. The tanks where I've achieved over 40 haven't involved any serious hypermiling techniques, but rather just not constantly stomping on it.

Same story the salesman told me; of course, the fact that they had no manuals on the lot did not factor into his recommendation.

I told him that I had just wasted three years of driving fun with an automatic tranny car and that I wanted a manual because... I wanted a manual. And that it had nothing to do with mileage.

i think the salesman was partially right, the mpg difference in newer cars is less than it used to be. in the yaris, i'd say 1-2 mpg.

i average about 38 summer, 36 winter mpg with my auto.

I have a 08 3 dr auto. I am getting 37.5 mpg during the winter and 39.5-40.5 mpg during the summer..I think your auto will be fine..As CTScott said that will depend on your driving habits..

I have a standard, my buddy has an automatic. We both drive about the same (fairly aggressive), but his is a 4-door hatch, I have a sedan. I get better MPG consistently. Which is eating the fuel? The transmission or the body shape?

The difference between the auto and manual depends largely on how you drive them. Driven "normally" the difference is very small but in the hands of a hypermiler the differences are much greater.

You can still achieve great mileage with the auto. I have a current lifetime FE of 41.9 mpg with a best tank of 48.0 mpg in my 5dr auto. Winter kills the FE. I'm doing more very short trips in the cold this winter and am only getting 37-38 mpg. Still pretty good but nothing like can be done in milder climates.

The sedan is more aerodynamic.

I laugh when people claim that autos can't be fun to drive, my Yaris is a blast on backroads and I don't miss my manual one bit! If you ever have to drive in the city, or in stop-and-go traffic, you'll be happy not to have to clutch!

Plus, you can manually shift an auto transmission, or you can let it shift on its own; but you'll never get a manual transmission to shift automatically!

And "Winter gas" does take its toll, but I am still getting about 33 MPG with my auto and larger wheels.

Cheers! M2

Think of the money you will be saving in not paying for a new clutch! The AT will, realistically, last forever.

MT is fun....for a while, but AT is far more dependable and adds to the resell value.

At one time in my life I thought that I would ever own an auto. Now I don't think I'll ever buy a stick again. Getting old.

Hi everyone,
I got 30mpg on my first tank full, but my tires weren't at their current psi (which is 39). I filled the dealer's tank half way, so I didn't get a very reliable measure there, but I'm hoping to get above 30mpg. I got that from my 1999 1.8L 4cyl. Corolla I sold to buy this. I read some people getting 37-38 in the winter, and figure I must be doing something wrong. Should I be doing anything (excluding high psi tire pressure) to maximize fuel efficiency? I am going to start driving 60mph and below and, as someone on this forum wrote, will act like there is an egg between my foot and the accelerator.
Thanks.

I've WOT my AT a few times and believe me, it's hard to believe it can accelerate that fast with only 90ish(?) hp. I can't even imagine how fast Garm's 350+ HP yaris will go at WOT!!

Ack sorry, this is the FE forums and WOT is a no go!!

The AT in the Yaris will surprise you.
(this ain't your fathers automatic)
Never thought I would be impressed by an AT after owning
MT's all my life.
