Why are MPG(US) and 100km/liter ratings do not match?
The question here is, why on earth for the same exact car in one country, the 100 km/litre consumption rates do not match with the MPG ratings in another country?
Ex; BMW 328i is supposed to consume 8.1 litres/100 km in city, 5.2 litres/100 km in Highway according to the BMW's Turkish website.
Now, these numbers converts into 29 MPG(US) in city and 45 MPG(US), if you google "xxx l/100km in mpg".
The problem is, the number in BMW's USA website is 23/35 MPG respectively for the same car.
Another example is Nissan Juke Nismo. The Turkish website claims a consumption rating of 9.1 and 5.6 l/100km, which converts into 26/42 MPG (US). US website on the other hand claims 25/31 MPG(USA).
For Prius C in US website the consumption is claimed to be 53/46 (city/highway) MPG(US) whereas in Turkish website it is 3.4/3.7 l/100 km which converts to 70/64 MPG(US).
The rating for US and European cars are different so the ratio of MPG(US) to conversion from Turkish websites should be constant right? or i guessed so...?
The following chart summarizes the above, and the it will be extended in the future for more cars...Now here is a spreadsheet including the websites attached on the consumption values;
