Xc90 D5 – Undermotorized?!

Hello together I drove yesterday for the first time the XC90 with the newer diesel engine (185 HP Veriante). The car came directly from the truck and had just 70km on it. I have to say it is a beautiful car, but under a T6 or V8 there is nothing. The acceleration of the D5 is comparable to the acceleration of the S60 T5 in the 5th gear. Is this normal that the diesel engine with at least 400 Nm is so extremely weak? Well and then the total consumption. I drove really comfortably, but I did not bring the average consumption under 15 L from 100km. At Volvo it is officially indicated with about 9.0 L / 100km. The D5 itself may be a good engine, but the XC90 in conjunction with this engine is extremely undermotorized. Gruss Raffi
