Hi
in the standard interior selection, the seats are partially in leather except in the center where your back rests against the chair. It also includes as per the configurator:
Includes in Smooth-Finish Leather:
- Steering wheel rim
- Gear selector and boot
With the leather package, there is more leather, As per the configurator:
Includes in Smooth-Finish Leather:
- Upper dashboard
- Center console storage compartment lid
- Seat centers
- Inner seat bolsters
- Front side of seat headrests (front)
- Door panel armrests (front and rear)
- Door grab handles (front and rear)
However if you select the ventilated seat option, the seat centers will be in leather. This was not obvious in the configurator. I chose a standard interior for 22MY and as part of the Premium Plus package, got ventilated seats as well. When I took delivery of my car last week, the seats centers were in leather.
Hope this helps.
