With the automatic, the 2009 is rated one point higher than the 2008 was (with the 1.8): 27/35 now, vs 26/35 for the 2008.
 
Sadly, the manual is now rated two points WORSE for both city and highway.

I don't care what the EPA says. A good driver can beat the automatic with a stick. Except maybe in ideal conditions for the auto (where it never shifts and stays in top gear) 70 (?) mph on a flat highway.

Tha automatic adds about 100 pounds to the weight of the car. A skilled driver with a manual will always come out ahead of the automatic; especially in heavy city driving. On the open road the main factor is speed. Anything over 60; and the mileage starts to drop.

Traditionally, I would have agreed with you without a doubt.
 
I question that possibility nowadays with the advent of CVT's. They are lighter in weight than traditional automatics, and can be programmed to maximize the powerband/fuel economy of the car.
 
I'm not contesting your claim about the manual getting better MPG, but it does make me wonder if it is still true, or at least, much more difficult to do now...
 
Just a thought....

If you can find an issue of the June 08 "Automobile" magazine, there is an excellent article about every available transmission in todays cars.(5 different categories)
 
 For the CVT the article states;
"PROS-Silky operation, potent passing"
"CONS-Minimal fun, high pressure hydraulics that sap efficiency"
 
Meanwhile for the manual;
"PROS-Utmost efficiency and control"
"CONS-Taxing in stop and go traffic"
 
It's a great article; unfortunately I don't seem to be able to find the article on their website

And a modern automatic (with lock-up torque converter) or manual can out-mpg a CVT while cruising on the highway, for the reason the article stated: "high pressure hydraulics that sap efficiency." They are of help in city driving, especially vs. an automatic, but not as much on the highway.
 
But then, the Corolla isn't offered with a CVT, at least in North America.

Well, I was referring to city driving...guess I didn't make that clear. Of course, a manual should always beat any other transmission on the highway, since it is a direct-connection, and friction has all but been eliminated with roller/ball bearings and modern lubricants...and, less weight, usually.
  
So, I guess we are in agreement...

you need to re-do the math. 45 liters= 11.89 gallons. 380 miles divided by 11.89 gallons equals= 31.96 mpg, not 38.39.
I have a 97 corolla 1.6 liter engine with a 3 speed automatic tranny and I am getting 34 mpg combined (city and highway driving). I get 38.7 mpg on the highway which is 30% more than the EPA estimate and I live in the mountains. How I do it? I put 4 more psi in my tires, I have a K&N air filter, and I put 2.5 ounces of Acetone per 10 gallons of gas when I fill up. Now I know the acetone mpg increase is SUPPOSEDLY a myth, and even Mythbusters busted this myth. What Mythbusters and everyone else don't realize is the first tank of gas with Acetone is basically cleaning your fuel system so you wont see much of an increase in mpg. You will see an increase in mpg on the second fill-up but it's the 3rd fill-up is when you see your maximum increase in mileage. I have been using Acetone in my corolla now for 2 years and my car has more horsepower and idles sooooo smooth now. Adding acetone does not work the same in all cars. I only get extra 3 mpg in my 85 Ranger pickup (V6-5 Speed) with 3 oz pr 10 gallons and 5 xtra mpg in my 92 Ranger pickup (4 cyl-5 Speed). I tried it in my Dad's 2008 Dakota quad cab 3.7 liter engine during a cross country road trip with NO increase at all, we actually got 1 mpg less. Like I said acetone does not work in all cars. For those of you who want to try it in your car, you must experiment to find the correct acetone to gas ratio. Mine is 2.5oz per 10 gallons gas. Try 1 oz pr 10 gals gas first time and record your mileage, then try 2 oz pr 10 gals gas and record it, if your mpg increased the try 3oz pr 10 gals gas. It's recomended NOT to use more than 4 oz pr 10 gals gas. When you start to see a decrease in mpg, then cut back 1/2 oz pr 10 gals gas at a time till you find your peak mpg. Thats how I got mine at 2.5 oz pr 10 gals gas and I think it would be the same for all 92-97 corollas with the 1.6 liter engine. You can purchase Acetone at Lowes, Walmart, Home Depot in the Paint Dept. I recommend buying PURE Acetone from a Beauty Supply Store as the more pure the Acetone, the better the increase in mpg. Also, ALWAYS use a funnel when put it in your tank as acetone is a paint thinner and the ingredient used in fingernail polish remover. I buy a 1 gallon jug from Sally Beauty Supply. I have a 1 pint plastic fingernail polish remover bottle, a funnel (the long skinny orange one from walmart automotive section, and a plastic 1 cup measuring cup with the ounces on the side to measure, all in a small cardboard box in my trunk.
ENJOY YOUR SAVINGS

I don't think that Torquecars.com mpg convertor is wrong buddy.38.39mpg is right.,
  .I have recently just filled up and am now getting 39.15 mpg using Redex and going by the driving tips for getting more mpg.
