V70 Bj.97 2.5 144hp…somehow lame. Is that normal?

Evening, I have to ask, if it is normal, that my V70 with 144 hp is probably the same with my old Golf 2 with 90 ps. Of course, the Gölfchen has only 900 kilos, the Swede 1500…but still I would have expected more. I am very satisfied with the car, the engine does not consume measurable oil, rust not, starts super, runs very calm and evenly, butter-soft, spritt consumption is with me in mixed traffic at about 9-10 liters. Also the ASU-Wer But still… I don’t get the feeling of the car getting in the pushes. Now I’m talking about the car being heavy… I wouldn’t even guess at a defect… What do you think? The fact and wonder is that I was able to speed up better in the fifth gear in the fifth gear with 1.8 liters and 90 Ps than in the same spot with the moose in the fifth gear. I also got up with the golf also climbs in the fifth, where I have to go to the fourth with the moose. Is the car really great? so cumbersome? The final speed on a mountain is the same for both….
