i can tell u that Corolla has been coming with SEKRUT heat-resistant glass since 2005, try and find that badge on prominent places.
If u look at glass of any Honda Toyota old gen vehicle, u will find a slight tint, a greenish shade which is non existent on this particular Suzuki.
Even old gen baleno got very goot heat/UV protection.
for experiment, park an alto and a corolla on the same spot in sun and place similar mobile devices on the dashboard, check after 15 mins, the device in alto must be showing warning that due to overheating applications have been closed while the mobile in other device wud be working okay.
i got this car and came to know this thing which i never experienced with other cars in decades.
