Tesla Semis reportedly charging at the Rocklin Supercharger station

The gap between the Tesla Semi tractor and trailer seems to have increased as seen at the Rocklin Supercharger station.

In a previous article we showed that the Tesla semi has a very unique feature to reduce aerodynamic drag. This drag reducing feature reduces the gap between the tractor and trailer. It also appeared to move during the reveal video. A secondary reason for the “movable” part is to keep the tractor from hitting the trailer when the trailer is cocked at a large angle.

A YouTube video (below) of the Rocklin Supercharger shows the trailer making a sharp right turn, and it appears that the panels are not moving. It also appears that the gap between the trailer and the tractor has increased compared to what was shown in the reveal.

Here’s the gap at the reveal:

This larger gap would tend to reduce range. We are not sure why Tesla has removed the movable feature and increased the gap. Perhaps it was a reliability issue ... or maybe this feature has just been temporarily disabled?

What do you think?

Thanks to my engineering partner Keith Ritter (aka HVACman) for spotting this.
