IONIQ i30 max fluctuation and experience?

Hello, I’m currently driving an i30 intro edition with 99ps gasoline and I thought about it, because I’m already a couple of kilometers in a row, to fix a new car for 2020. since diesel is currently being talked quite in the ground I thought that a hybrid wouldn’t be bad and therefore I came across the ioniq because all the others (bmw etc) are extremely expensive. however, I don’t understand, even with my small 99ps air pump I have a maximum speed of 182km/h in the distance but the ioniq has a 140ps gasoline in it and also “only” 185km/h in it. does that have what to do with the matures or is the motor just locked off because of the battery? otherwise someone has experiences with the ioniq in how much he is doing well in consumption with city and highway? PS: what do you think of hybrid vs diesel? because per se I would rather buy a diesel but rather think about it through the whole diesel based it on short or long for priv Attitudes will be very bad.
