Volkswagen Polo Bluemotion
Even though this car is banned, it’s actually one of the most fuel-efficient Volkswagen’s we’ve seen. It was modified to have longer gear ratios and the body was designed to be more aerodynamic… So, it’s too fast for the US. But, with those designs, the car produces less than 100g/km of CO2 and can get into 74.3 mpg.
