Hybrids or small?

The cars which emit less than 100 grams of CO2 to the kilometer should be generalized. The hybrid car is often heavy and top-of-the-range, small cars are less energy consuming, especially with improvements of the style cameless and stop and start.
Thus the CO2 rejection rate is of the same order for Citroen C1 as for Toyata Prius, around 104 grams for 1km. Moreover, the environmental impact of C1 is weaker, it is lighter, occupies less space and is easier to recycle. A display of instantaneous petrol consumption would flexible driving, which moreover would decrease the accidents.

To present the hybrid cars as a source of energy saving is more marketing!
The best solution to decrease energy consuption are:
to decrease the car use,
to drive slowly,
to use a small car!
