Ampera), and they tend to be more efficient, particularly if you
charge the batteries overnight at lower cost.

The Prius is far more economical (in terms of fuel consumption) than a
diesel engine car when driving at low speeds in urban streets
with innumerable stops for traffic signals and other vehicles.
On open roads, particularly motorways, a diesel is more economical.
Previously I was driving a diesel engine car and I'm very conscious
of the difference in my fuel consumption!
