One year has passed since I got my Toyota Prius. I have been keeping a record of kilometres travelled and gas consumed. The average consumption over approximately 13000 Km has been about 5 lt/100 km. I have an Excel file here, which contains a graph of ‘lt/100 km’. During the past year I have tried to let the tank empty as much as possible and then fill it up with 20 Euros. However, sometimes this was not possible, so you will see some spikes in the graph; these are artefacts of the recording procedure. The true average consumption is calculated as the total amount of litres over the whole year divided by the number of kilometres travelled.
Overall, I am still very pleased with this car. The only problem is limited visibility, especially towards the back.
