Tesla Explains Why It Dropped Sunroofs From Its Vehicles
Tesla says low usage rates and service complexity led to the switch to improved fixed glass roofs.
Tesla executives have clarified the rationale behind removing opening sunroofs from their vehicle lineup, citing low owner usage and increased service complexity as primary factors.
What Happened
During a recent segment on Jay Leno’s Garage, Tesla VP of Vehicle Engineering Lars Moravy and Chief Designer Franz von Holzhausen discussed the design choice while showcasing the new Model Y L. The executives explained that data indicated owners typically used opening sunroofs only when they first acquired the vehicle, with engagement dropping off significantly afterward. Moravy and von Holzhausen also noted that sunroofs are mechanically complicated components that frequently require service attention.
Why It Matters
The decision to eliminate opening sunroofs has allowed Tesla to focus engineering efforts on enhancing its fixed glass roof technology. According to the company, newer glass roofs feature improved laminated layers that reflect heat and block UVA and UVB rays, along with a reflective silver coating and integrated antennas. Tesla claims that the Model Y L’s roof reflects up to eight times more solar energy and admits 30% less solar heat into the cabin compared to Model Y vehicles from 2024 and earlier. This thermal improvement, combined with HVAC upgrades, contributes to an estimated seven-mile increase in real-world range during hot weather conditions.
The Bottom Line
Opening sunroofs appear unlikely to return to Tesla’s current lineup, as the company continues to refine its fixed glass roof solutions. Future developments may include a patented perforated glass roof design that integrates with the HVAC system to manage air flow and reduce noise.
