Geely's 48% efficient hybrid engine

[rafalg]

it looks like below, which is roughly similar aerodynamics to the Berlingo on your pic.
Of course we dont use mpg here, so the nuance of UK vs US mpg didnt occur to me at all.
In metric it's 5.8 liters/100km, which is ~40 US mpg. And you will see numbers like 3l/100km when going 80km/h steadily - even in 20 year old diesels. So i believe this could be improved even further (for hybrids etc), if Europe did not decide to throw the tech away. Only now the producers realize that this was their true advantage...

This looks even bigger, and wonderfully narrow.
40mpg USA in this kind of vehicle is still incredible.

Pretty big inside, and kind of grandpa's car, but it's a good suburban workhorse. Can move kids, furniture, wood planks or bicycles
