Roof glass and A/C

[Mchaelme]

When I viewed the Mach e here in the uk the guys with the car said it will have an electrically light controlled adjustable glass roof, wonder of its been dropped due to cost or reliability issues ?

Interesting statement. I have never heard that before. It certainly wasn't mentioned at the presentation that I attended. The only thing that was said was that it was coated with a special coating to prevent uv rays getting through so as to keep the car cooler in the summer and warmer in winter

I've heard that same report in the UK from another member (wonkey_donkey), but i think the marketing guy saying that was misinformed. Other than at that UK event, there has never been mention of it.

I have a Model 3 with a glass roof and have installed shade on the front and back glass. I does slightly reduce heat from IR/light. But, this does not do much for comfort. The glass itself gets very hot and is not insulated like a normal roof with a head liner or moon roof cover. With the a/c on full blast, I can put my hand or my bald head near the roof and feel the heat radiating off of it.

Sounds like Tesla needs to incorporate better coatings into their glass.

they added a glass ejection option for free.

The first picture I believe was the hood. But either way, eek!

There are a lot of 70% ceramic window tints out there that reject around 80-90% of infrared energy. I usually tint my windshields with it and it makes a big difference in heat rejection.

The Polestar 2 is evidently coming with electrochromic "smart" glass in its panoramic roof, which can be dimmed to translucent or even opaque; this type of glass is used in the new Boeing Dreamliners for their passenger seats, where you push one of several buttons to have the window go from completely transparent to completely opaque. All automakers should be using electrochromic glass in roof glass.

Toyota has that type of glass too.

I can answer this question!

When I was speaking to the Ford guys in London they explained that it had an electrochroamatic layer built in to the glass - so when it's sunny it will automatically darken to prevent overheating and glare. (Just like some rear view mirrors have to stop the car behind dazzling you at night)

So technically no shade or cover should be required.

I do not think it "darkens" or lightens in any way

I merely reported what I was told way back in the early days by Ford representatives... and would agree with what we know now, it is unlikely that this made it to the final design.

It doesn’t. It is a high quality low-e coating however.

Totally agree.

In my defence I noticed from this thread that there were a couple of others that were told the same thing at the London event - but we should bear in mind that was waaaaay back in February when we were very light on detail.

I do love it when zombie threads just pop up to bite you in the arse 10 months later ?

No, from seeing it in person and confirming in a webinar Q&A, the glass is not electrochromic. It is low-e tinted.
