Recently, Tesla revealed a new all-glass roof option for the Model S, similar to that shown in Model 3 prototypes. Twitter user, Nick Hoffman, was gracious enough to post some videos and pictures so that we could all see it in “real life.”

The Model S all-glass roof option will cost $1,500. It will attempt to keep out the sun’s harmful rays, with ultraviolet treatment. The glass is also infrared, so it keeps out heat (how about some innovative application for those in more frigid climates?).

This all comes as a product of Tesla’s new “Tesla Glass” division. The company is manufacturing its own glass, primarily for use in the newly-unveiled Solar City glass roof tiles. The glass will also be used in all of Tesla’s vehicles.

Tesla CEO Elon Musk pointed out that the Model S’ body is now even safer as a result of further reinforcement that took place as part of the glass roof application and installation.

“The Model S all-glass roof option will cost $1,500.”

Uh . . . isn’t glass much cheaper than aluminum? I know on a price per pound for recycled material, aluminum is an order of magnitude higher price than glass. I don’t know if the manufacturing of this particular autoglass is super expensive though.

I just wonder if they are getting a higher price for a cheaper to manufacture product. If they are, very clever of them! Perhaps this pricing will change eventually as the novelty wears off in order to direct people to the cheaper(?) glass roof.

But someone correct me if I am wrong.

Then a sunroof should be cheaper as well, b/c its just glass some plastic and some metal parts. Its not just the cost of materials, its cost of production and application of said material.

According to this a glass roof can also reduce production cost: http://insideevs.com/hole-in-roof-key-to-mass-production-of-tesla-model-3/

Well a sunroof generally has additional mechanical aspects for opening & closing. Plus lots of work sealing it to make sure it doesn’t leaking. Add I think they make them by cutting the existing roof instead of having a different roof structure so you don’t save much on aluminum.

It’s a “feature” so it will be more expensive no matter what the material cost is. 😛

Now if only they could make a glass that opens to turn the Model 3 into a hatchback 🙂

it wasn’t a simple matter of pulling off the aluminum roof and throwing on a glass one. they would have had to reinforce the frame to accommodate for the lack of structural support in the roof. that’s why convertibles are more expensive than hard top cars even though the roofing material in a convertible might be less expensive.

furthermore, that’s a custom piece of glass. you can’t compare prices of raw materials and assume that finished goods prices will show the same comparative pricing as raw materials.

“it wasn’t a simple matter of pulling off the aluminum roof and throwing on a glass one.”

There’s no roof to pull off in the first place.

“they would have had to reinforce the frame to accommodate for the lack of structural support in the roof.”
“the all-glass roof essentially makes the model S a convertible.”

While some reinforcement was probably needed I wouldn’t go as far as to compare a tempered-glass roofed car to a convertible. That’s BS and you know it.
Also, in that particular space, a sheet of tempered glass offers the body way more rigidity than a sheet of aluminum.
Here’s a look at the truss and aluminum sheet roof:

“i’m not suggesting that it was trivial for tesla to make this modification”

It WAS trivial!

Now hold on there. The problem with the roof ISN’T the actual glass pane. The problem is the ATTACHMENT from the glass pane to the roof structure. This attachment point is typically either a rubber seal or glue (reference the way most automotive windshields are installed) and as a result of this there is almost NO structural integrity imparted by the glass panel. Were this not true the first hard bump would crack the roof glass. Now, I can’t testify to the rigidity of the Tesla frame– I would assume that the subframe of the vehicle should be quite sturdy as the pack is supported by it– but the body is GOING to need additional rigidity because connecting the A-pillar (the windshield pillar) to the B-pillar (between the front and back doors) by two thin strips of metal versus a 5 foot wide hunk of aluminum is going to seriously compromise rigidity of the body cell as a whole– the aforementioned bump would cause both front doors to get stuck. The fact that it’s *perceived* as an upgrade to the vehicle, means that they will of course charge more for it, even if it made the vehicle cheaper to make.… Read more »

What?! What car maker uses rubber seals these days! They went out 10-20 years ago and are now virtually *all* bonded. And to imply that a toughened/laminated/both (for all we know) glass roof has little or no rigidity is absurd. I would expect it to provide considerably more than a this sheet of Alu even with whatever hidden bracing it has (if any).

the problem with glazing isn’t its lack of rigidity; the problem is the way that glazing loses structural integrity when it breaks. so in the “sunny day” scenario, glass works great. but you have to design structures for what happens when things aren’t so sunny. that’s why you don’t see buildings that rely on glazing for structural integrity.

Aluminum is very light. Glass is not. To cover the roof you need a certain amount of material regardless of weight.

Also when you build something you have to consider yields and costs of installation. I have to imagine it costs Tesla more to build a car with a glass roof than with an aluminum one.

$1500 more? Surely not.

Perspective from a Masters in Comp. Sci (AI) guy who has also run 2 companies: A glass roof may be cheaper to make, but Tesla has to recover their high initial R&D cost of development. They hope to recover it from all who purchase the option in the first year or two. For example: Suppose it cost Tesla ~$1,000 for each glass roof. This leaves $500 per car for glass R&D. If they get 20K orders, they got back $10 Million in R&D the first year. After its paid for itself, that option’s profit soars or else they can even make it a standard feature in future years, to save money on materials and labor over an aluminum roof.

For example, in the late 1990s, Bill Gates said that to create each new version of Windows costs them about $100 million for the first copy. All the other copies were just a few dollars. Since nobody (outside of govt.) will pay $100 million for just one copy, this huge cost has to be spread out over all of them. Once that cost is recovered, the profit margins can be huge.

In very high volumes I imagine the glass can become quite cheap but considering all the of the R&D and technology associated with this heavy duty – UV/Infrared resistant glass I assume there is no way it will be cheaper for them in the near term. Automotive aluminum is quite cheap.

Looks awesome though. I am sure they can make good margin on $1,500 if they sell enough of them and I bet they will with the model 3.

you’re going to want to *really* hope that you never have to replace a windshield. because if you do, you will learn that automotive glass isn’t as inexpensive as you apparently think it is.

to me, that looks like an expensive piece of glass. that looks like a piece of glass that is custom made for the tesla model S. under what basis do you think this glass will be produced in “very high volumes”???

What does the roof have to do with the windshield?

did you read the article??? in case you didn’t, the article is about a *glass* roof. guess what kind of material is used to make a windshield?

Here’s sort of a data point:

“Sorry if I’ve made things a bit confusing. Hopefully, I can make it more clear now. The windshield itself costs $880. There are other parts involved in the replacement/repair. Total parts cost was $1044 (or $1094; can’t remember….). Total Labor cost was $250. The total $1370 figure includes taxes and everything.”

I think it’s safe to guess that a Model S glass roof replacement would be about $2000.
We’ll just have to wait and see .. I’m sure it’ll “make the news” when it happends.

Looks amazing!

it’s clearly an “eye of the beholder” kind of thing because it doesn’t appeal to me at all.

No its not. I don’t like sunroofs but it looks sexy.

Doesn’t matter if you dont like it or not.

It looks the same to everyone with functioning eyes.

It is crafted the same way.

the statement “the glass is also infrared” isn’t really a meaningful statement because it is the treatment that is applied to the glass that seeks to block infrared waves. what this means is that tesla applied lo-e coatings of some sort (i would presume pyrolytic) that block both infrared and ultraviolet wavelengths. the filtering of UV and IR isn’t perfect so a lot of visible light gets blocked as well, as you can see from how dark the glass appears in the photo.

blocking infrared works at both high and low temperatures although for single lite glazing there is a limit to how much temperature resistance that glass will have. specifically, the coating can reflect impinging exterior infrared waves, but some of the temperature energy will get absorbed in the body of the glass and then re-transmitted into the interior of the car. on the other side of the coin, infrared waves attempting to escape from the car would also be reflected back into the interior.

I just assumed that the “the glass is also infrared” comment was a typical editing error you see these days with writers having to self-publish as fast as physically possible.

Obviously it is going to have to block infrared wavelengths or the interior of the car is gonna get hot enough to cook the passengers. It would actually reduce the range of the car as it will increase the load on the air conditioning system, as well as the fact that glass is HEAVIER than aluminum.

Is that crosswise structural support moved further back in the new glass version??

It’s gone on the all glass version.

the photo was taken at an angle from the driver’s side. so what you are seeing in the roof is a reflection of the passenger-side pillar and headrest.

Is a really impresive solution. Structure is gone. Im just wondering how they keep the shape in the lateral impact. Maybe the glass is specially strong and helps to keep the shape of the car.

the all-glass roof essentially makes the model S a convertible. auto companies know how to make convertible cars. i’m not suggesting that it was trivial for tesla to make this modification, but that i don’t think that a breakthrough was required.

With North America and EU in winter, we need someone in Australia to make one a video. I’d love to see a thermometer in direct sun inside the car. Then cover the roof with a thick white sheet and repeat the test. Let’s see the temperature difference.

Those commenting on temperature and such seem to be overlooking the fact that the Model S has had a pano roof option since forever, and it’s almost as glassy as the new one. It works fine.

Hope this is translated to the final Model 3 design, so it can now have the same lift back opening, instead of #TinyTrunk.

The glass roof makes you loose the roof rack mountings.

So does the metal roof. The only roof which has rack mountings is the sunroof model.

I just saw the glass in person. I feel if the headliner and the interior is all black it probably would look awesome. Before you add it with light color interior, see it in person. I saw it today with the light interior and it had a bad reflection from the back seat. Kind of like….. looking out of a fish bowl. I ordered it before I saw it in person and with my car all black it should look great. If I were to do it again maybe I would stick to sunroof option. Will post more when I receive the car in two weeks.

i suspect that you are going to see reflections regardless of what color you choose. in the photos shown in this article, it looks like the interior is black and you can clearly see reflections in the roof. it’s a byproduct of the coatings on the glass that are used to block ultraviolet and infrared wavelengths. you are also going to be able to see your own reflection when you look at the roof as i’m sure you saw. one other thing to consider is how light through the roof will affect your ability to see the screens. from the photos in the article, my guess is that it should not be a problem.

this feature doesn’t appeal to me at all for the very reason that you noted. i don’t care for the “fish bowl” experience.
