KIA Sportage 2.0 l + 2.7,V 6, questions

Hello, I am playing with the idea of buying a KIA Sportage. I have once sent myself the current brochure of the Sportage. Especially with the 2.0 l petrol and the 2.7 l V 6 a few questions arise: how is the V6 in the suit quite lame, from 0 to 100 km/h it needs 0.1 sec. more than the 2.0 l ? why is the final speed registered at 180 km/h ( V 6 and 2.0 l )? It can’t really be that a round 141 hp car ( 2.0 l ) is more splashing than an approximately 175 hp Auto ( 2.7 l V 6 ). Only in consumption I find a certain logic, the V 6 is definitely more pure. 🙂 But seriously: I don’t know from the technology why a buyer should increase the V 6. Well, the standard equipment in V 6 has already what, but purely from the technology? Can one of you give me “insider tips”? Many greetings, gobecks
