new car due – X1/X2 Xdrive 25e useful?

Have a meal here in the round… read with me here in the forum for a long time and have signed up now because I have a few questions that are currently stuck in my head…. and I have no solution… unfortunately our x1 i25 is a Monday car and hopefully goes back soon… because we are basically satisfied with our friend, we hope for a good offer to stay at BMW…. now the question of course is… X1/X2 Hybrid a real Alternati ve…? the following requirement profile: daily approx. 30-45 km (50% AB and 50% city – all unfortunately in traffic jam…) long journeys are put back with our other car. Luggage compartment no topic would load I have read at home now something into the PHEV topic… according to paper would my requirement profile be designed for it or? But quite isn’t it with purely electric driving or? As soon as I give a little more gas the petrol engine switches to it – so I have it at least t understand, or is there simply no more power when I’m on the road purely electric? Or is that a marketing thing… and you can’t drive purely electric with a PHEV? Then I would have to start to reckon I don’t really see if it makes sense to switch to the X1, X2 hybrid… or it doesn’t make any sense to drive purely electric or to get a pure petrol engine again… ev. a smaller machine… eg X1 Xdrive i20 I hope it can jeman bring the light into my darkness…. 😉 thank you already… lg from Austria
