Fisker’s upcoming all-electric SUV will feature some kind of innovative roof system which allows occupants to enjoy the open air.

Henrik Fisker took to Twitter to preview the system dubbing it the ‘California package.’ The successful car designer’s post includes a photo of the control panel that’ll be used to operate this roof but it’s hard to know exactly what we’re looking at. The tweet also reads “All open, without being a soft top; first on an SUV.”

If the Fisker SUV with the available California package does feature a roof design unlike any other, that would seem to eliminate the possibility of a large panoramic sunroof as heaps of other cars on the market offer such roof designs. Most panoramic sunroofs on the market allow drivers to either crack open the front half or slide back the front half to enjoy an open-air experience. Could the Fisker SUV allow owners to slide back the entire glass roof panel? It’s possible but we will have to wait until the SUV is unveiled before knowing exactly what it has designed.

The electric car manufacturer dropped a new teaser for its SUV in mid-June and the example pictured appeared to feature a traditional sunroof.

What we do know for sure about the vehicle is that it will be powered by a pair of electric motors, one of each axle, and feature an 80 kWh battery pack which should provide an estimated range of 300 miles (483 km) on a single charge. Key exterior design elements of the car teased in the past include turn signals mounted on the D-pillar and LED headlights.
