When I first heard it, I thought it would basically mean that they will use TPU (more durable plastic) in the interior trims than the regular plastic being used in a standard car. Like the steering wheel grip has a different / rubberized plastic, similar to that I think.
Or, it could be that the side door panels will have a TPU trim like Aspire?
But since you are already planning to buy this car, you can simply ask the dealership while / before booking it. Also, please do let us know what they say.
