XC 90 test driven:-(

Only the 2.5 lt. Diesel drives sooo sluggishly that it is red again at the traffic light until you could drive away and the automatic transmission from our tractor is smoother. Too bad. Now we will drive as soon as possible the petroler times. The new 2.5 Diesel has a few HP more under the hood, however, it will not be a new car with us. What are your experiences? Also in other concerns with the XC 90?Od. can someone give me something about the Be nzin consumption?
