So hot!
 

That's what I'm usually saying to myself when I turn the vent on in the FR-S. Why the heck is the vent air so hot compared to the outside temperature. I've never owned a car where there was this much of a difference. Any way to fix this? I hate turning on the AC if I don't have to, but even today at 73 degrees outside, it feels like 90 inside the car.

So close the vent...

Big problem with our cars.
Air is coming from the blower sucking air from the engine compartment.
Engine compartment is so damned sealed that not much fresh air flows through it making the blower blow hot air into the cabin.
This is one of the contributing reasons why the FR-S has power issues in warmer weather and complicates forced induction applications.

but I like air. it's in my top 3 things I like. just ahead of food and just behind water.

Open the windows? Or, like you said, AC.

Using AC does not affect MPG much, despite popular belief. Use it and enjoy your cold air.

I wish our cars had windows that rolled down. That would be neat.

If gas is your concern there are other ways.

Or just roll down your window like everyone else is saying.

First world problems.

I wish that was true... for the past 2 weeks LA has been quite warm... 90's...

Usually it's like 60-70... and during that time I would get 30.1 MPG.

With the AC on... I'm getting 28.23 MPG.

I stopped driving at 75 MPH (30.01 MPG AC OFF) to 65-70 (28.23 MPG AC ON) in hopes to get better fuel economy.

Checked my tire pressure... I'm sitting at 36 PSI cold...39 Hot.

So from the information gathered from the past 2 weeks... I've noticed a loss of about 2 MPG.

Turn the air vents on full blast, direct them out the windows. Instant +10hp from keeping the engine bay cool.

Or run a CAI pipe directly to the cabin air filter. You could put a BOV on it that went off when you changed fan speed.

I should clarify, rereading the OP, my post is vague.

Using the AC compared to the vent - yes, vent will preserve MPG.

Using the AC compared to rolling down the window - negligible due to aerodynamics. Better to just use AC.

So in summary, you're correct that using AC affects MPG by a small amount (since the engine has to turn the pulley that turns the belt), but when compared to the other solution of rolling down the windows, there's not much of a difference. Our vents suck due to the layout of the parts in the engine, so it's not often we get to enjoy the vents for cooling purposes :respekt:

Hey now. Be nice.

If your cruising down the highway at 70 MPH on a 90F day and open the widows, you get 90F air hitting you in the face at 70 MPH.

:thumbup:

I don't even use the heater. Just the heated seats.

Welp, schmearcampain, as mentioned, that's just the nature of the beast.

You can:

* punch the recirc button to close the vent
* turn on the A/C for a minute or so to cool down the vents
* turn on the A/C and leave it on
* open a window

Your call ..... ;)

went for a spirited drive in the mountains yesterday and rolling down the windows it flooded the cabin with hot air, which was nice because it was cold outside but I wanted an open air feel. Just sayin:iono:

Why would you want that?

Kind of leads me to something I've noticed that I really like about this car. In most other cars, I drive w/ windows up most of the time just so I don't get wind in my face/blowing around hair. In the 86, windows down doesn't really seem to bring much air into my space. It's nice to drive window(s) down!

Slightly off topic, but this car has the coldest A/C of any car I have ever owned.

Not for me.... unless my AC is defective :iono:

Did your previous cars have ac? My ac won't even keep cool if car is not moving. Under any engine load compressor also turns off and instantly depletes cold air supply. Only really gets cold on hwy with partial throttle. Took to dealer and they said it's fine. Damn south Florida humid heat year round

So let me get this straight. It's 90F and you're complaining the uncooled air from the vent setting is too hot? Do you understand what the vent setting does? It's just outside air. Which as you said, is 90F. I'd think the problem would be obvious.

And if a difference of 1.75 MPG is going to break you, why the hell aren't you driving a hybrid or an electric car?

It was 86F/70% RH here yesterday. Windows down feeling fine. Only turned on the AC as I was pulling in to get things prepped for my girlfriend who hasn't adjusted to humidity yet(we moved from the CA high desert where 15% is considered humid).

lol, this car REALLY needs remote start! I can understand why it doesn't but in 2014 on a car that on some peoples budgets isn't cheap, this is almost unforgivable with the Scion line of cars in Toyotas brand. I'n my tC I have to roll the windows down leaving work because I don't want to drive for 5 minutes with them up dying in my car hot waiting for the AC to fully kick in!

Maybe its a Firestorm thing then, because mine will freeze you out after just a few minutes on anything higher than 2 on even the warmest day. That black interior sure does get hot fast when the Sun is beating in though.

I can't leave my ac on the coldest setting either or my fingers go numb.

No, air is coming from the outside via the cowl panel. Just open a window.

Where do you live? I'm looking at temps in 90s/100s and very humid.

I'm sorry but if you're living in LA and are stable enough to have a car like the FR-S, than you have no room to complain about anything.

Noticed this when I got the car, always bothered me. Wind up using re-circulate or close vents.

Not just a firestorm thing, my ravens AC makes your snot into ice sickles on (2). Cars thermo said 93 yesterday as I was leaving work. Turned AC knob all the way to cold, set fan speed to 2. Before I even got out of the parking deck I was seeing my breath.

I will say though, turning the AC off, my car becomes almost instant hot box.

My AC is also very cold, but so was my Jeep way back when it was new. The difference is that the volume of air inside the BRZ is so small that it takes no time at all to cool it down. I usually run it full for a couple of minutes to get to a comfortable temperature, then turn the temp to 68 degrees and turn the fan to the lowest setting.

Thing is 90 degree temps outside around here usually mean decent air temperatures, with the vents on in my other cars the air would be about the same as ambient, in this car it's NOTICEABLY warmer, at least 5 degrees I'd say. Cruising along with the windows down and the fan on you can move your hand between the vent and the open window and feel how much warmer it is, pretty lame when you're used to a nice low fan setting with the windows up on the highway with the AC off. I have to run the A/C anytime it's over 75 degrees, sunny, and too uncomfortable to have the windows down, most of the time it's set to the warm side so I don't freeze.

Not a dealbreaker, just not something most people expect or notice on the test drive.

Edit: My A/C does very well up until about 110 outside, then it starts to struggle unless you're on the freeway.

ITT, makin' mountains out of molehills.

Atlanta, so I get my share of heat/humidity. I took this shot during 2012.

Yea definitely agree on that one! That's why I need louvers (but not TRD $1000 louvers)!

whats that suppose to mean? LA is gross

Last summer, we had a couple 38+Celcius (48 or something with humidity) (Like 120F or something idonotcare) days. A/C had no problem cooling the inside of the car within about 2 minutes. In the winter I keep the cabin at 19.5 and in the summer, because the A/C blows so cold, I usually have it at 20, and my S/O is keeps hers at maybe 22-23.

Big AC unit + small car interior FTW. Also, I have the 'whiteout' colo(u)r.
