Question: is my 170 ps petrol engine an effective one? Hello people, please ask for advice/technical information from knowledgeable forum colleagues: have ordered me an S80 automatic with 170 hp petrol engine, because I wanted a quiet engine (this is supposedly louder), but it has enough power to speed up the relatively heavy S80 with overtaking maneuvers at 80 to 100 km/h on the road and petrolers are used to. However, when comparing with other car brands there are doubts: 1. eg ein ung about the same Mercedes with 163 hp petrol (200k) only needs approx. 8 sec. – this also applies to other equally strong gasoline from other brands – with the S80 Aut stand 9,9 sec (at 170 hp!) on the data sheet ==> is the Volvo 170 hp petrol a bad engine for acceleration/overtaking? 2. the 170 hp petroler brings full NM only at rd 6000 Umin – the diesel or the turbos already at 2000 u/min – that means that I can clean up well only on very high tours and with envious speed digkeit or when “Cruisen” with 70-90 km/h can not be properly accelerated? 3. please ask for experience values, how the 170 HP petroler behaves with overtaking maneuvers from 80-100 km/h. Thank you for your experience values or feedback Wolfgang
