Hello together, I have been driving a C5 (combi) from 2010 with the THP155 for several years and have now bought a caravan. What I immediately noticed: The car feels quite overwhelmed by this despite the 155hp. The caravan weighs empty 1150kg and with our basic equipment maybe 1350kg. The car was also only moderately loaded with two people and a trunk full of clothes for 4 days, linens, a few supplies etc. When I write that the car is overwhelmed. I mean concretely: – consumption over 16l, when I try to hold 100km/h – 100km/h means full throttle at slight gradients, at slightly stronger gradients switch back to the 5th (and full throttle) – acceleration is virtually not available (starting on the highway in the 3rd with full throttle to reach to the end of a commercial acceleration strip 80-90km/h) Now my question: Is this normal or expected behavior for a petrol engine? I would have the 155ps after all. twas more trusts and asks me if something is wrong with the car. Does anyone have experience with it or maybe even a similar team? Thank you in advance!
