16th refuel on the Prius today.
After having traveled 879 kilometres on this fuel tank, I added 43,3 liters.
I was aiming for that el cheapo petrol station that gave me good results in the past, but it didn't accept my debit card, so I went on to an Esso station on the same road (which was actually cheaper! it's a road where they compete!).
The Esso price was €1.319/l.
The analysis of this fuel tank is as follows:
4.926 liters per 100km (Prius meter showed 4.6 = biggest difference ever). This is all the more suspicious because I was on 4.5 after 500km when it went to 4.6 and I expected to be teetering on the edge of 4.6 again. Admittedly, it was my usual motorway routine and big airco was needed for the whole period.
Converted to other measurements, this means:
47.4 MPG USA
56.93 MPG Imperial

Look up higher in this forum (posting 7 or 8 in the P.S.).
I personally tested the hacked Prius (62kg of extra Lithium Ion batteries - including the Valence Technologies kit - in the boot, equipped with a normal electricity plug - for plug-in recharging) in the Summer of 2005. The battery performance was spectacular; the cost as well...
There is a real possibility that I'll decide to go for it... but I'm also looking out for proper hydrogen propulsion (fuel cell if needed) before making the jump.

P.S. Went to the car wash with the Prius for the second time today; it's still black and shiny; but washing was imperfect and I have an inexplicable scratch on the hood :-(

P.S.1. After refueling, I drove in EV mode to my office 2km further. Including this distance would have put me in high 4.5s.
P.S.2. These stats suggest that doing 1000km on a fuel tank (capacity 45l) might just be possible.

Yes, I know about the 'bladder' (see my post of 21 Nov 2005 in this thread), which is why I have reported my own measurement and the Prius computer readout on every tank since day 1.
My own measurement is based on the fuel I put in, and that I pay for, so I tend to think that that should be my reference.
(Overall, after 10.000km, I must be at 5.1 ish liter/100km, so the result is consistent with G. Sommer. I don't know when G. Sommer got his car, but for me it was Sep 2005, so the average includes more winter than summer and we are Europeans driving fast on motorways. When I go to other places than my office, which do not involve motorway driving, and temps are higher like last week, I see it visibly dropping to 4.7l)

I passed the 10.000km mark on the Prius today.
The car still works fine, I haven't done any maintenance of any kind (and only visited a car wash once...). The only problem is still the rattling noise of the security triangle (I taped the triangle down in the trunk but it still sort of rattles inside its box).
Today, I also made an early fuel stop (Refuel no 12) at the petrol station that I know has a tyre inflator machine that shows BAR and PSI, and automatically pumps air until the amount you preset. I put all 4 tyres on 40 PSI/2.8 BAR (yes that's high, but lower than done by Prius fuel efficiency freaks). It's only the second time that I inflated the tyres, they were around 2.4 BAR. You immediately feel the difference when at 2.8.
The analysis of this fuel tank is as follows:
After having traveled 823 kilometres on this fuel tank, I added exactly 41 liters. The Total Excellium price was €1.415/l (i.e. expensive).
4.98 liters per 100km (Prius meter showed 4.9 - this is the tank I used on motorway to Germany and back - so pretty positive rating on the Shell V-Power fuel, if these supposedly special fuels make a difference).

11th refuel on the Prius occurred on 3 April 2006 (in The Netherlands on the way to Germany; I refueled somewhat early because I know that the motorway I was going to take in Germany has few petrol stations).
After having traveled 798 kilometres on this fuel tank, I added exactly 43 liters. The Shell price was €1.445/l (i.e. very expensive).
The analysis of this fuel tank is as follows:
5.38 liters per 100km (Prius meter showed 5.0 - i.e. a big difference - I was on 4.9 for most of the tank but followed-up by long motorway driving).
Temperature was mixed, some very cold days around freezing, some days above 10 degrees centigrade.

The Prius is optimised for minimum environmental impact in terms of emissions, not low MPG.
I have written before that some (smallish) diesels have similar or even better fuel economy than the Prius, but they generate puffs of black smoke... (and that smoke contains deadly micro-dust particles and makes historic buildings go black).
Solar Hydro
P.S.1. I had read that article comparing Lexus and Mercedes SUVs. They are at double my consumption and probably a multiple in noxious emissions.
P.S.2. This whole thread was triggered by Bismarck's request to me to receive real-world Prius statistics (as opposed to claims and brochures).
P.S.3. Might be interesting to put your Mondeo and my Prius together for a 0-100km/h test. I have not tried hard accel, but the brochure says it takes 9.5 sec from standstill to reach 100km/h. If you car has those HP and torque metrics, you might win, but not by much ;-).

Hello ALZY and all,
This thread (largely at Bismarck's request - see near the top), keeps track of real-world Prius performance in a continental European country. It is, and will remain, an honest account of the car's life, and my driving behaviour/experience as its only driver.
I haven't had any problems (yet?), but I will be brutally honest in reporting any problems or issues (see also my post criticising some aspects), and the car's maintenance track record will be reported. I was told by the dealer on purchase that the first maintenance would be either at 15000km or 1 year (Prius enthusiasts say you should change the oil earlier, I haven't). I think I'll hit 15000km earlier than 1 year (I passed 6000km today).
The Prius is optimised for environmental performance, over and above fuel efficiency (little diesels will match it or even beat it on pure fuel efficiency).
My name is Solar Hydro for a reason.
Hydrogen direct vehicles have worked for some years (I still regret not buying a BMW 7 HL in the Internet boom times. Even if it would have been a bit difficult to refuel, it would have looked nice in my museum).
Fuel cell vehicles have worked for some years, can even be leased today on a more or less commercial basis (The Honda FCX has been leased to governments/companies/rich families but the price is not realistic for the average consumer and the refueling infrastructure is not practicable today for general purpose use). I firmly expect that it will eventually become economic (compared to transport alternatives), but the price point is/will be influenced massively by overall energy economics (which are extremely thwarted by commodity supply conditions/sources, environmental conditions and differentiated taxation). I fully expect to be a very early adopter of a fuel cell vehicle, but I'm afraid that it's unlikely to be imminent.
I remain on course for the purchase of an expensive a plug-in hack for the Prius (I personally experienced a long urban drive in an experimental hacked Prius with 62kg batteries in the boot, and its performance was objectively spectacular, even if the electronics and battery placement were a bit pre-industrialised).
The OLFSL crowd is invited to type 'Toyota Alessandro Volta' in a search engine. Sadly, it's only a prototype, but effectively built... and worth having a look at. Speed is electronically capped at 250km/h.
Meet ya on the track!

Hello again,
I went to the car wash with the Prius today for the first time, a little over 4 months after taking delivery of the car (I don't EVER plan to wash it by hand!). I needed that car wash because the salt spray from the roads had obscured the side windows and especially the little window under the rear spoiler a bit too much, which impeded visibility. It's quite difficult (for me, I'm not very tall) to reach over the roof to take off the little antenna, so perhaps the car isn't that low after all.
In addition, I did the seventh refuel on the Prius later in the day. Quite quick, because I drove 600+ km to Amsterdam and back the other day, with suspicious green battery almost all the way while driving mostly 120-124 km/h for the whole distance, with limited sections at 100-104km/h. I attribute the green battery to the low outside temperature which was 2-3° centigrade. The Prius meter was showing a flat systematic 5.5l/100km on that trip. It was remarkable to see the completely constant readout on the meter. (Holland is flat).
After having traveled 788 kilometres on this fuel tank, I added 45.0 liters (the fuel tank capacity is... 45 liters), deliberately choosing an 'el cheapo no name petrol station' to check whether the 'el cheapo' fuel makes any difference. (the price was €1.14/l, my dad paid €1.31/l at a branded petrol station the same day).
The analysis of this fuel tank is as follows:
5.71 liters per 100km (Prius meter shows 5.4, on the edge of 5.5 where it was earlier in the day), i.e. I keep racking up worse results over and over... as the temperature gets lower, but this tank was the max on motorway distance for sure.
Converted to other measurements, this means:
41.19 MPG USA

P.S. Taking advantage of a passenger for the trip to Amsterdam, we managed to isolate the developing dashboard rattle noise (I am notoriously sensitive/hysterical about rattle noises in my cars) as coming from a little grid on top of the dashboard screen. When pressing a finger on it, the noise stops, so I'm hopeful that it can be fixed.

Bismarck asked me for real-world performance statistics (high up in this thread); I am providing them
The car fully meets my expectations, until now, but I've only had it since 3 September 2005, so it's early days yet to judge.
Points I don't like: rear-window visibility is poor (strange rear spoiler), too many electronic beeps for all kinds of 'features' (including reverse gear), fuel gauge not detailed enough (doesn't have a countdown in km like some recent cars), the emergency triangle in the boot gets loose and rattles (I've fixed that a few times, but it starts again after a while, need to think of a permanent fix), traction control and stability control cannot be turned off, a new little rattle in the right front door (I HATE rattles, need to look into fixing that one), the plastic wheel covers, still looking for proper rims.

Ack, I needed another pitstop after all before the end of the year...
Sixth refuel on the Prius today.
After having traveled 774 kilometres on this fuel tank, I added 43.5 liters (costing 55.55 euros, Q8 brand), yielding:
5.62 liters per 100km (Prius meter shows 5.3), i.e. by far my worst result.
Converted to other measurements, this means:
41.85 MPG USA
50.26 MPG Imperial
Temperature in the past weeks was around freezing for several days, we had snow again, and I had to wait for my colleague to defrost her car's locks with my engine idling for 10 min (from cold start while it was freezing = very bad for fuel efficiency). Note: The Prius doors can be opened with the key in one's pocket... it's called "smart entry" and it works ;-)

Fifth refuel on the Prius today.
The colder temperatures clearly have a major effect on Prius fuel consumption, although the temperature surely affects any car's fuel efficiency.
After having traveled a meagre 811 kilometres on this fuel tank (using the Total Excellium fuel discussed before), I added 43.10 liters, yielding:
5.31 liters per 100km (Prius meter shows 5.2, was fluctuating near the edge of 5.2 and 5.3 all the time).
Converted to other measurements, this means:

princess:frosty::wizard:Fourth refuel on the Prius today.
After having traveled a meagre 841 kilometres on this fuel tank, I added 44.65 liters (by far the most, pretty near the end of the 45l capacity), yielding:
5.308 liters per 100km (Prius meter shows 5.0).
Converted to other measurements, this means:
44.31 MPG USA
53.22 MPG Imperial
Explanatory factors include:
- Even more motorway driving (went to a far away airport);
- Getting stuck in several LONG traffic jams (after 30 min of start/stop crawling where the Prius is awesome, it desperately wants to charge the battery);
- Heating (last days were 2-5-8 degrees centigrade); the Prius heater is amazingly quick, you get real heat in under 1 minute from cold start.
Now I've grabbed that Total Excellium fuel again for a second try, to see if their claims have any veracity.
Note: the Prius fuel tank contains a 'bladder' which responds to temperature and air pressure etc, which explains (I hope) the differences between the Prius meter and my own measurements. Then again, my maths might well be completely wrong.

P.S.1. The price was €1.288/l for 95 octane
P.S.2. Bad start: after 1 day Prius meter shows 5.3l/100km.

My best to-date is 3 little green cars on a single 5 minute bar. Achieved by decelerating slowly with just a little braking on a motorway exit ramp.
Today, while driving home I managed to use 0.2l/100km in 5 minutes on a downhill section and then using EV mode in town, with half a little green car as a bonus. I have been trying to do well there, traffic lights were favourable... (usually I have 1 1/2 little green cars there because I have to stop for the lights).

I now have two movie sites in the post above...
YouTube streams, but it's choppy with starts and stops (at my office, on my home ISP it streams fine).
Vimeo takes minutes to load, but then it plays smoothly (at my office, on my home ISP it loads instantly)

Hello Tweaker and all,
As requested, here is a movie of the Prius dashboard screen while driving. It's rather shaky, but covers the various system states (petrol engine, electric engine, both engines, no engines, braking and stopping) ;-)

or

(the movie doesn't stream well on YouTube over here; on Vimeo it takes minutes to load with a blank screen, but once it plays it plays smoothly)
I have also posted dashboard pictures on:

I didn't say that it's a beautiful car, and didn't buy it for the looks.
The shape is optimised for aerodynamics. The windshield angle is very small and the roof is sculpted specially to make the air flow (I didn't know that until I got the car, it's really weird looking from above).
There is also an air diffuser at the bottom rear like on the big GTR cars ;-)

Strange comment, the Prius is actually not tall at all. I'm not tall at all myself. Perhaps my picture is misleading ;-)
