I have been driving a 9.5, MY 03, 2.3t Kombi for about 1 year. So far the consumption was about 75% urban and 25% AB according to SID between 12.5 and 13.5 l/100 km. On longer fast driven AB routes with many full-gas accelerations and brakes, the consumption could also exceed 14 l/100 km quickly. Quite exactly after exceeding the 15,000 km threshold, I had at once a consumption of 11.5 l/100 km despite high urban traffic share. On a subsequent AB journey of 500 km was the Consumption at once at an incredible 9.8 l/100 km. However, I did not drive very fast because of numerous traffic jams, construction sites and viscous holiday traffic (95 km/h average speed according to SID). But where it was possible and allowed, I also drove more than 200 km/h. On the return journey the track was freer, so that at an average speed of 135 km/h a consumption of 11.4 l/100 km resulted. I am faced with a mystery. If it is imaginable, d as SID broken, have I unconsciously changed my driving style or has the Saab only really moved in now?
