Toyota Prius real-world fuel consumption figures?

CiniO

Toyota prius the previous model (2003 to 2009) with 1.5 engine.

I know fuel consumption / economy specified by manufacturer. It goes like this:

urban: 56.5 mpg (5 l/100km)
extra urban: 67.3 mpg (4.2 l/100km)
combined 65.7 mpg (4.3 l/100km)


Where can I find the real everyday figures, as I doubt those specified by manufacturer can be really achieved in everyday traffic.

Especially what I want to find out is what the consumption would be in following circumstances.

1. Driving on country roads in mountain regions with good bit of inclines and declines.
2. Driving on country roads with full load (5 adults + luggage).
3. Driving at high speeds on motoways (150 - 160 km/h).
4. Driving in a city in harsh winter conditions (snow on the road, -15 degrees, etc).


If anyone is able to give me at least approximate values or any website where I could find such info, I'd be very pleased.


Thanks.

Won't be easy to find exactly what you're looking for. :P

These 100mph motorways are in Poland presumably?

Presumably yes.

You will be at near flat out speed. Forget about economy, or slow to feck down.

Prius has electronically restricted top speed of 180k/h.

I just asked a question about fuel consumption.
I'm aware that at higher speeds consumption will be higher, but wanted to find out how much higher, as it's different with different cars.

F.e. my current Mazda 6 2.0 petrol does about 7.5 l/100km while driving steadily at about 100km/h, but it takes over 10 l/100km when doing 150 - 160km/h so difference in economy is really big.
For my friends accord 2.2 diesel though, it makes very little difference whether you are traveling at 100 or 160km/h.

That's why I want to know how it looks like in Prius.
Can I expect figures rather about 6l/100km at 160km/h or more likely 10l/100km?

I'd expect even more than 10l/100km.

Might be something near what you are looking for.

There is loads of threads on speed v mpg on both priuschat and ecomodder showing graphs and data on speed v mpg for many cars. Even a honda accord, every car I have even seen this data for uses more fuel at 150/160 than a 100.

The air resistance can't be avoided and there you will use exponentially more fuel the more air you try to move through in a given amount of time.

EDIT: Apologies wrong model of prius but a search will get you the same and less techy graphs for the MK2.

That shows some really interesting figures. Thanks.
