The MPG is even worse. I drove the Volkswagen Polo from 2012 for seven years. It was the four cylinder 1.2 liter turbo engine, which had 90 horsepower with a manual transmission. I sold that car after seven years, because in that time it had way too much repairs for a car of that age. There were also electronic failures which cost me a lot of money to getting them fixed.
Back then, the car was
officialy advertised with a 47MPG (5 l/100km), measured by the standards of this awful NEFZ method. Nowadays we have WLTP standardised in Europe, but this is still not as good and realistic as EPA. But at least it's closer to reality than NEFZ.
The combined milegae of the car based on several
german car-related media was defined at
35 mpg (6.6 l/100 km).
I managed to get a overall mileage of 37.6 MPG on 43.000 miles (72.500 km) I drove.
On a gas tracking website were a lot people tracking their gas fillings, there were 120 people which had the same car, with the exact same engine and also manual transmission, together they had 37 MPG.
My one and only hypermiling-story with this car so far:
I drove it from a full tank to till the engine went off on purpose. By that I was able to reach 745 miles (1200 km) with a single tank. That was a MPG of 51 (4,7 l/100 km).
Even though in a hypermile community 50 MPG are sounding not like a very good achievement, I was pretty proud at that time.
And as I mentioned in to other posts, I'm living in a city and have constantly to deal with traffic jams, stop and go traffic and the Autobahn, all of these things make it a bit hard to be a good hypermiler.
