Does anyone knows what is
Windshield Athermal Infrared
and how does it work?
I have just received my New Stelvio Diesel with the above included in "Convenience Pack" but I have not idea what is it?
It is a passive filter layer in the windshield that blocks some of the sun's radiant rays to reduce the load on the a/c system. Temp is claimed to be as much as 10 degrees cooler (maybe 10%) on a hot day.
As my wife and copilot is subject to hot flashes, I've been championing its benefits even if it doesn't do a darned thing for benefit of the placebo effect. With the advent of spring we'll be finding out soon whether it's something or nothing!
Having searched the interent for more info on this mysterious amazing high tech innovation, all I could find was anecdotal references to 5 year old BMWs. Anybody else?
IR glass is similar in principle to low-emission glass in a house. I know low-e works because I have it on my house and my utilities bill is puny for my size and climate. It isn’t a make or break kind of feature but it doesn’t generally hurt to have IR glass in a car, blocking half the IR spectrum should help keep it cooler.
Now a heated windshield like Jag offers would be fantastic in winter after we get clipped by an ice storm which turns into snow.
