Ventilated Seats

Starting to configure a new E450 and need to know if the ventilated seats blow cabin air as in the W213 or actual AC air?

My Ford Edge has ventilated seats that have an AC duct so the air is cooled. On the W213 models there is no duct and the ventilated seats just blow air.

For the W214, MY 2025 has this changed and actual AC air is being blown or just recirculated air, basically a fan.

Thanks in advance.

I believe it's just the cabin air, but I'm not 100% sure. What I do know is that they are effective at cooling you down. I had my 2025 since August and a prior 2024 E350 from April to August. I used them quite a bit in the hot TN summer and they worked great. I would get them regardless since what is most important is the do they work. It's possible that the air duct for the rear is somehow tied to it, but I'm not sure. It feels cool but not cold when they are on. Just right in my opinion.

By the way, if you are thinking about the seat heating. The rapid heat option is great and even better is the additional heat on the center console and door arm rest. My wife loves that feature. She didn't know it had them until she turned on the heat for the first time and was pleasantly surprised.

While there are many things to like about this car, the whole interior climate control system is a noteable bright spot. Hot or cold, the car is quickly comfortable in any outside temperature. The only negative is the lack of rear climate control. For reference, I have the multi-countour seats and opted for rear heated seats.

It only blows ambient air. I’ve never felt any refrigerated air. I had a GMC Denali that had cooled seats and you definitely knew it.

On my 2019 E450 I have heated seats and heated steering wheel: This is my fourth car with a heated steering wheel and because I go north to ski this is for me a mandatory option. I drive with my arms fairly straight and do not rest them on either the center console or the door arm rest plus in the winter I usually have a coat on so this extra area to me at least has very little value - but glad you wife loves the feature. 99% of the time the only thing on my rear seats are my skis - seldom are they occupied by humans, so there is little reason for me to get heated rear seats.

Thanks for the input about the ventilated seats being cabin air and not AC air. As I said on my 2018 Ford the air is actually AC air. I was hoping the same on the MY 2025 but it may not be.

Thanks. Yes on my Ford you definitely feel it being AC air and it is really nice. I think $450 for a fan to blow cabin air is a bit much. I find the AC in my 2019 E450 makes me quite comfortable. I think I will pass on the $450 fan.

On my '18 E300 there are HVAC vents on the floor under each front seat so that the ventilated seat air is cooler than the air higher up in the cabin. I wear shorts 90% of the time and I can feel the difference when I turn on the seat fan.

Thanks. I think every Mercedes has those vents - mine does as well. Those vents are to cool the rear. As cool air is denser and tends to stay low rather than rise, having a fan above in the seat to blow air up through the seats will only blow normal air not the AC air.

This is basically a $450 fan. Shame Mercedes could not splice off that vent and direct some of the AC cooled air through the seats.

Many years ago in Europe (1970's) buses advertised forced air conditioning: It was a vent in the roof and as the bus moved air was forced into the bus. Certainly not AC! Mercedes is doing the same 50 years later! Forced air but not cooled air as in my 2018 Ford at half the price!

My 2020 E450 has heated and cooled seats and though I live in the mid-Atlantic with warm humid summers I may have used the cooled seats a couple times in last 2 years… is it worth $450? I’ll always want it for the few days in a year I may actually need/use it. In the grand scheme of things, $450 in a $80K is a rounding error.

As the old saying goes, “best to have it and not need it than to need it and not have it” or something to that effect.

Of course ymmv. It’s your money so choice is always yours.

As you have used the ventilated seats, is it ambient air or cooled air from the AC?

Some of that cooled air is sucked up by the fan, otherwise I wouldn't be able to feel it.

Of course you would be able to feel it even it there is no direct duct work: anyone who stands in front of a fan feels cooler - even if the air being moved is 90 degrees.

As you have the ventilated seats can you confirm there is no direct AC air being supplied, only ambient air being moved by a fan?

Thanks.

If you’ve ever had true cooled seats, you’d definitely know the difference. On my Denali the seat would get cold - almost to the point of feeling like your pants were wet.
My E450 is just blowing room temperature air. The only pleasantry I’ve noticed is that it stirs up the new car smell from the seats… 😉

Thanks. Exactly what I have in my Ford Edge. The temperature is constant and cold. After 5 minutes I usually start to lower the fan speed.

Wife wants an All Terrain but this is a deal breaker for her.

Yeah, it's rather unfortunate. I asked for it before my car was built and my salesman raised it with MB USA but they said it couldn't be done. Same thing for getting the lower dash and door trim to match the cabin color (Brown/Beige), for whatever reason the NA models exclude that and four zone climate control. I even said I'd pay for the four zone climate control.

It's a shame, because the four zone climate is available in the E53's pinnacle trim here. I wouldn't be surprised if it ends up an option on the E350/450 for 2026, but that doesn't help us right now

Deal breaker for me, too. Was planning to order a new W214 AT and return my current W213 AT (with rear AC) lease, but thanks to those product planners they are losing a new car customer.

But I won't be getting a Hyundai.

At times I have rear passengers but I still almost hate the 4-zone HVAC in our W223. I cannot see why the rear would need different settings from the front, not even the front passenger different from the driver. I always set HVAC sync on if someone has messed with the individual settings. Rear is a pain as you cannot immediately see if rear settings have been adjusted.

The only real benefit from 4-zone in some cars is that they have additional nozzles for the rear windows. Only needed in very cold weather with the car full of people.

The southern USA can be very hot and humid in places so many need it for hot weather.

Those kids and pets need to stay cool.

Just to add the detail here because I don’t see it mentioned anywhere, the ventilated seats pull air through the seat. They do not blow air from the seat into the passenger. This allows them to pull the climate controlled air to the surface of the seat as well as cooling of the seat interior. Yes, they are not as good as air-conditioned seating or cooled seating as it would be called but they are very effective and personally I’ve never had anything else so I’m not missing anything.

If you’re wondering why it doesn’t have the technology of some other vehicles, that’s because this technology was incorporated by Mercedes nearly 15 years prior to other companies even thinking about this type of option. With patents and technology ip, one could assume there might be a greater reason Mercedes doesn’t have cold seats, but they do have air scarfs for the convertibles which I believe existed prior to air conditioned seats in other brands.

Unfortunately, Mercedes is no longer the technology leader for many of the doo-dads people seem to value in modern car technology. This has now lead us to the sacrificing of superior mechanical technology for subpar electronic technology. Most of us can see this complete breakdown of the car industry.

It now comes down to each individual buyer, but to think that somebody would want to drive a Hyundai boys sludge bucket with air cooled seats over something more refined in every way that doesn’t have air cooled seats is for each individual to figure out..

I wouldn't drive a Hyundai either but Mercedes needs to up its game if mass market brands offer desirable features that it doesn't offer. Protect the brand image.

More likely an Allroad is an option since it has rear climate control as standard. Arguably better looking than an All Terrain but not as extensive of a dealer network.

I still don't understand why the All Terrain doesn't have an AMG Line Exterior option so all the black plastic bits can be body paint matched like the wheel arches in this All Road picture. I think the AT would look a lot better, and I'd be less sad about the classic wagon not being sold state side anymore.

First the E450 AT was being compared to a Hyundai and now to an Audi A4 wagon. What’s next? - maybe compare it to another mass produced mammy wagon such as the Subaru XT all bcos of rear climate control…
