This is the result of two days driving to work and back home. It is mainly Highway. The soft top was on, and I was alone in the car. I tried to drive carefully, but not too slowly. On the highway I was driving at 100 to 110 Km/h. For some time I did drive in heavy rain with wipers and with air circulation. I allways drive with lights on. The car was in normal mode and charging was standard. My car has now around 10 000 Km on the clock and is from february 2010, Sport.
