Auris Hybrid Ordered
Discussion
For any doubters about hybrid performance i just got through my first full tank in the prius i am using as a work car. Normal prius not the plugin. It's a 2010 t-spirit model too.
It has had a true mix, mainly A-road where it is perfectly suited, with town on nearly every journey and about 10-15% motorway. I averaged 71mpg exactly according to the trip computer. That is 0.5mpg above official average. It was calculated to 67.8mpg using the fuel receipt.
It is also very good on the motorway. I had no issue achieving 64mpg for a motorway roundtrip with cruise at at 75mph. At those speeds it was hovering around 61mpg but with the more economical bit either end it averaged 64mpg.
Electronics are complex and probably confined to an ECU and a hybrid ECU but the moving parts seem much less complex than a diesel, less smell, no mess, no nasty noise, no black soot, no tax, more economical, generally more space inside. As a commuter it is excellent and it rewards you with the correct driving style and that doesn't have to be slow either!

If it's only doing 35 mpg either it's poorly or being hammered to death.
Even Richard Hammond couldn't batter it down below mid 40s mpg overall when tested for Top gear magazine, and the owner reports on Honest John are averaging over 50 mpg.

Is there a page on that site listing cars by real mpg?Even Richard Hammond couldn't batter it down below mid 40s mpg overall when tested for Top gear magazine, and the owner reports on Honest John are averaging over 50 mpg.

What, you mean a list of all the cares covered from A-Z?
Not all on a single page: you have to go in via each maker from here:

I meant is there a lsit where can you see what are the best performers?
If I wanted to search for a 75mpg+ car how would I do it without having to go into each make?
This may come quite close to what you want but is not broken down version-by-version:If I wanted to search for a 75mpg+ car how would I do it without having to go into each make?

The Honest John 'real mpg' database is not so good (IMHO) since there is no sense of sample size. Also the 'top performers' section is irrelevant - I don't give a monkey's chuff how well a car compares to the official NEDC figures, I just want to know what the most economical cars are.

Honest Johns figures look the more real world with the Prius on 56.9 and the Yaris on 53.9

mm to me it's the other way around

I not sure if I understand? Honest John has the Yaris Hybrid at 57mpg and the latest Prius (non plug-in) at 56.9. If I understand the website correctly, no sample size is given for the Yaris and there is data on 357 Prius (2009-on)Honest Johns figures look the more real world with the Prius on 56.9 and the Yaris on 53.9
Spritmonitor has the Yaris Hybrid doing 58.5mpg (sample size 531) and the latest Prius (I searched for 2010-on to eliminate the earlier generations) at 55.8 measured over 457 cars.
They seem to agree pretty well?
And now I have now you ressurected it ;-)
One thing missed from the Hybrid VS diesel compirison of engine complication is the lack of a high pressure direct injection rail needed in a petrol hybrid (or even plain old petrol)
I've known a few people with Derv cars having problems with the high pressure fuel pumps and injectors getting burned/clogged etc. I thought it was about 2000PSI in a modern TDI common rail engine but just went to google to check that - and it's 2,000BAR. Or 29,000 PSI. Holy smoke no wonder they break down a lot. Where as some figures I got for petrol is 6.5BAR in the fuel pump and 200BAR at the injectors.
As a hunch it's becuase derv is sticky and thick so needs more pressure to get it to atomise.

Just stumbled across this thread. I'm taking a test drive in Hybrid Auris on Monday.
Questions - what sort of range do you get from a tankful please? Also is the trip counter accurate?, as I'll test actual mpg on a typical journey!
I had one for a week on demo. Range depends on how you drive it, but I'd suggest 450 miles is about right, it's not got a large tank. I found the MPG calculation by the car to be reasonably accurate, mine only under-read by about 1-2 mpg, which is pretty good in my experience.

Admittedly, I only filled up once, so have a sample size of 1, but averaged a real 58 mpg in general running, including a couple of motorway trips. I was trying to drive normally, although the car encourages a relaxed approach, which is no bad thing I think.
I achieved high 50's, low 60's on the motorway, mid to high 60's, into the 70's around town just following other traffic and not being too much of a hooligan.

Those figures for petrol are the direct injection systems. A normal port injection system thats far more common is only 3-4 bar in the fuel rail.
Ooops, reading back what I wrote is looks like I'm saying the petrols need a high pressure fuel rail.. when I meant the dervs!

I run the prius for work which is essentially the same car despite weight and aero differences. Questions - what sort of range do you get from a tankful please? Also is the trip counter accurate?, as I'll test actual mpg on a typical journey!
I believe the tank is the same size but smaller than diesels for example due to better efficiency.
It costs roughly £48 to fill completely after about 550 miles driven, I did ht 600+ once but I drove for nearly 60 miles after range hit 0. Throughout the summer the prius has averaged between 67 and 71mpg. I've just done a fairly long motorway trip and it averaged 67.4mpg actually very high considering I spent most of the journey doing "true motorway speeds"
Good luck with your test drive.
I have the 7-seat version of the Prius which has the same engine but a slightly more powerful electric drive.
Fuel tank is about 35 litres not counting reserve. I normally get about 450 miles out of it. This gives real-world consumption of about 58mpg which roughly matches the onboard computer (in fact it's slightly higher).
In winter it's less, I reckon I get between 50mpg and 55mpg in winter.
It's pretty impressive for a 7-seat MPV.
I think they are great. They do lack flair but they are highly practical and the hybrid drive stuff is pretty cool.

A friend of mine bought the posh Prius (the Lexus CT200h) new in 2011 and he's struggling with his consumption, averaging mid 40's mpg ( link). He's in his 60's and retired so most of his driving is pottering about which I thought would have suited the way the hybrid works but seems not.
He's a bit disillusioned with it. There is no 'knack' to driving these hybrids efficiently is there?
