Where’s the progress?

As a winter car I drove an over 20 year old Audi 80 with 1.3l and 60 hp. It was noticeable that the fuel consumption was quite up to date. On the track I could move the car on average with 6.3 l normal 100 km. There is the question for me where the progress is. Of course, there can be no talk of spooky, but I was never as a traffic obstacle on the slopes. If I then have to see what ach so modern diesel still consume then we are not very far away ==References==
