There are a lot of good reasons above which I also agree with, but they’ve all also forgotten a very big reason.
1 US gallon = 0.83267384 Imperial gallons
Therefore 50 MPG in the UK is only 41 mpg in the US, even if they are calculated in exactly the same way for exactly the same car.
——
first european cars have smaller engines than american cars do because the cars are taxed based on engine displacement.
second european cars are lighter than american cars are due to the lower safety requirements.
third european cars have less stringent emission standards than american cars do.
fourth european cars are tuned for better engine performance, and better efficiency than american cars are due to higher fuel prices, and the demand for high performance even in the smallest of cars.
all of the above assumes gas verses gas powered cars. european diesel powered cars are even more efficient.
