I’m well placed to answer this – I have a Prius.
The car is quite efficient in the summertime, in the absence of traffic and not on a motorway. I can get 4.2 L per 100 km (my wife’s diesel car never gets below 6.5 L / 100 km).
In the winter – when the weather is cold I get less than that because the engine has to be at 150 °C for it to work – and sometimes you’ll end up burning fuel just to keep the engine hot.
This is especially true if you’re in traffic and the car’s engine cools down (on average I get 5.4 L / 100 km in the winter).
The car’s batteries recharge from braking and therefore you don’t get a lot of battery power produced when you’re driving on motorways. So you want relatively free flowing traffic – with lots of stop / start for excellent efficiency (driving downhill helps as well!!).
The best I’ve ever done is 3.8 L / 100 km, when I had nearly an empty tank (so I was carrying less weight) during a very warm week this summer (when traffic in Dublin was very good).
Sorry I’ve gone on – I like talking about the Prius….

You are always having the most interesting questions 🙂
For sure I’d like the hybrid car for very good reason. A hybrid car is one that uses more than one means of propulsion. At the moment, that means combining a normal petrol or diesel engine with an electric motor (money-savers). The chief advantages of a hybrid are that it uses less fuel and emits less CO2 than most conventional non-hybrid vehicles. So we can decrease the global warming that threats the Earth by using hybrid car.
So it has a lot of advantages like:
1. Environmentally Friendly
2. Financial Benefits
3- Less Dependence on Fossil Fuels
4- Regenerative Braking System
5- Built From Light Materials
6- Higher Resale Value
However it has disadvantages like
1- Less Power
2- Can be Expensive
3- Poorer Handling
4- Higher Maintenance Costs
5- Presence of High Voltage in Batteries
Hope this help 🙂
is there any way to reverse the aging process?
What are the components of a computers microchip
hi do you know the way they say that you cant destroy energy nor can you make but technically if you use up the power
What kind of materials are you using to make our future fuels more environmentally friendly
