Hello, I would like to buy a Volvo V 40 soon. In principle I would be more interested in a petrol engine. Depending on consumption and maintenance costs I would also choose a diesel. If I want to drive the Volvo V40 as cheaply as possible, which engine should I choose? Does nothing need to be agile, I would only like to come from A to B cheaply. So which is the most economical diesel and which is the most economical gasoline engine and how much do the engines consume? Greetings and thanks, Felix
