However, the S on NBR has 7 seats ( I think) instead of 5 and this will grant Tesla a record nevertheless.

How can that car have seven seats?

It's just emergency seats for kids or very small adults.
When not in use the seats can be retracted into that space where the feet are suppose to be while seated. I think Tesla discontinued the option two years ago so the car running on the ring must be an old "shell" on top of that Plaid-drivetrain.

Not sure why Elon even mentioned that in a tweet and having 7-seat should just add weight. But we should take his tweets with a grain of salt as usual.
