FR-S/BRZ MPG

[serialk11r]

^^ lol er...thanks?
ryude how are you getting that conclusion? If say he gets 40mpg on the highway portion of his commute (let's say this is most of the 90 miles) with the manual, and 10% better with the auto, he'd be using 2.2 gallons of gas for the manual vs. 2.05 gallons for the auto. 0.15 gallons * say, 300 days, is 45 gallons of gas, which at 4 dollars a gallon is 180 dollars a year. I'm predicting better than 40mpg (at 60-70mph), and I may be overestimating gas price so let's say 160 dollars. 6 years to pay off the auto, assuming he ONLY drives on the highway. In the city, he may not necessarily lose mpg if he avoids using 1st gear past getting the car rolling. The auto box also needs to power its hydraulic pump, which would sap some amount of energy too.

I agree. It will take about 5 years but not over 10 years to make up $1000 initial cost.
If the mpg is 10% better the annual fuel spending will be 10% less.
If one spends $3000/year the difference will be $300/year and will take little over 3yrs to get $1000 back.

The automatic gets 3mpg more on highway, which means average mpg will increase by 1 maybe? 1mpg is so insignificant that it will take you a very long time to recoup the extra cost. If you're going to buy the automatic, don't buy it for the fuel economy. Buy it because that's what you really want/need.

Will the gearing be the same on the FR-S and BRZ? Because I am going to get the BRZ.

Auto vs manual cruze eco.

Annual Fuel Cost Auto: $1,635 Manual: $1,536

But in the real world, the difference is very minimal.

It will probably be the same but you never know...

EPA highway test favors manuals as it involves a lot of changes in speed. Real world highway driving favors locked automatics, which almost always have higher gears.
EPA city screws autos over as it should.

^ true that.

just manually shift the auto so it stays at low rpms in the city... i heel toe everywhere in my manual even at low speeds out of habit, if i go the auto route ill be upshifting and downshift manually ALL the time

That's what I do in my Evo X MR

Well you don't want to accelerate at too far below 2000 rpm since the engine loses too much heat to the cooling system at low speeds, but it's okay if you do that in 2nd gear since you got out of 1st gear early. Anything is better than an unlocked torque converter.

I'm not sure how gear spacing would change the equation. If the gears are spaced out farther then the auto would theoretically lose more energy to the engine needing to slow down more to match the next gear's speed, but effect is probably very small.

is 3000 rpm at 60 mph normal or high?

Premium gas only?
