Better Model Y Juniper range due to quieter A/C with oscillating vents and double-coated panoramic roof

The new Tesla Model Y Juniper facelift comes with the same battery as its predecessor, but its official EPA range estimate now pegs it as good to cover 327 miles on a charge, or 5% longer than before.

Tesla engineers explained that this is due to a number of efficiency improvements, both in exterior design, and cabin energy consumption.

While the more streamlined exterior is evident, bringing lower coefficient of drag from restyling down to the new brake calipers, the power draw enhancements from the various cabin comfort features have just been revealed.

First off, the cabin A/C can now operate at much lower fan speeds with the same efficiency. This is due not only to the new oscillating air vents that turn from side to side to disperse the hot or cold air more efficiently, but also to the new sunroof.

The panoramic glass roof now has double silver coating that improves its thermal insulation properties to the point that the HVAC system needs less energy to heat up or cool down the cabin.

Coincidentally, the measures that Tesla took to improve the HVAC efficiency such as lower fan speeds and better air distribution or thermal insulation also added to its next major goal for the 2026 Model Y Juniper facelift, a much quieter cabin.

Tesla carpeted everything it could inside, down to the cupholders, the side trims, and the trunk lids to prevent rattling noises.

This, coupled with the new acoustic glass all around the Model Y Juniper refresh, has led to a significant reduction in cabin noise, to the joy of those who want to take full advantage of the new audiophile-grade sound system.
