We measured cabin temps before and after ceramic tint installs in San Diego summer heat. Here are the actual numbers.

We've been measuring real cabin temps before and after ceramic tint installs all summer. Here's the actual data.

Test setup

Same parking spot, full sun, 1pm, July–August in Vista. Cabin temps measured with an IR thermometer at dashboard, steering wheel, and seat.

Before ceramic tint (factory glass)

• Dashboard: 162°F
• Steering wheel: 148°F
• Black leather seat: 152°F
• Cabin air: 124°F

After 70% front + 20% rear ceramic + clear ceramic windshield

• Dashboard: 138°F (-24°F)
• Steering wheel: 124°F (-24°F)
• Black leather seat: 130°F (-22°F)
• Cabin air: 106°F (-18°F)

What this means

• AC reaches comfortable temp in 2–3 minutes instead of 8–10
• EV range improvement: 4–7% in summer
• Your interior stops fading
• The car is genuinely usable after 30 minutes parked

ROI

Ceramic tint pays for itself in saved AC fuel/range and protected interior in under 2 years.
