Impreza locked down?

Hello together I’ve been the owner of a new Impreza’s Ecomatic with 110Kw since May. I’m also very happy with the car. But, can it be that the car is somehow sealed off at 210 km/h (according to Tacho)? At this speed the car spins about 5,700 rpm. It also doesn’t matter if I drive with gas or gasoline. He doesn’t want to go faster. My friend has no explanation for this yet.
