Auris Hybrid Ordered
Discussion
My wife has been running a Yaris Hybrid now for just over a year, I like the fact that you can do long journeys in it if required and don't have the concerns about running out of juice, which once you dial it into your journeys is fine I guess but not one for us. Overall she gets nearly 70 mpg out of it all of the time and I use it for local running around and being a sports car man can actually live with it for short periods.
In fact I'm so sold on the Hybrid thing I'm looking at secondhand LS600h's.

I've been running the Auris Hybrid Estate since November.
So far I've put 10K on it.
Average MPG is 55.
Not as refined as some would have you believe, the Anderson cycle engine can sometimes seem to rev it's nuts of for no real reason (Especially in 'B' mode).
Auto trans can be a bit clunky.
I've had to have the drop links done at the first service.
The airbag / seatbelt light is a real pain, fixed by some black tape.
Plenty of space though, and handing is only a little worse than my previous hack, a Golf Mk6 Bluemotion estate.
Overall I'm happy with it, especially as a 40% tax payer, cos it saves me a shed load of money to feed petrol to my V8

Good point about the engine revving, I have tried to explain to my wife that on dual carriageways you have to look much further ahead than usual regarding the planning to overtake slower vehicles. Alas, I might as well talk to the hand, but as town/local roads are concerned you can't beat it.

The revving you talk about is because of the CVT box, that's how it's designed to work. Maximum efficiency, all the time.
Trust me, after 7+ months with it, it's clunky. Mainly on take up on drive, or switching from reverse to drive, or vice versa.The revving you talk about is because of the CVT box, that's how it's designed to work. Maximum efficiency, all the time.
I'm well aware of CVT boxes, as my first company car, over 25 years ago, was a 1.4 Fiesta with a CVT box.
However the drivetrain of a Toyota Hybrid isn't a true CVT box.

Sounds like something is wrong in your final drive, or drive shafts / UJs. The transmission itself doesn't have anything in it capable of clunking.I'm well aware of CVT boxes, as my first company car, over 25 years ago, was a 1.4 Fiesta with a CVT box.

It shouldn't be clunky at all. The wheels are connected to the engine/motor using a planetary gear system. This is always connected and so shouldn't clunk like a regular transmission as nothing actually moves when shifting between gears. When reversing, the wheels are only powered by the electric motor. The engine doesn't do anything apart from come on sometimes to keep the battery pack charged. The "B" setting on the gearbox is used to control the car down a steep hill, it does this by using engine braking. That's why it revs higher when selected. Only use this function for that purpose.
Oh, it's an Atkinson cycle engine btw.

Sorry, how are they more efficient and less complex?
Diesel engines are very simple mechanically compared to petrol engines, are not burdoned by complex regenerative braking and automatic fuel switch technology ... as for reliability that is largely much of a muchness these days.

Diesels have alternators and fuel injectors dont they?
... making it, although 'different' actually quite a simple piece of machinery: sophisticated through basic design rather than complication.
If there is anyone left on here who has not yet had a play with the Toyota hybrid drivetrain simulation to get a feel for how the oily bits transfer various forms of energy into movement and vice-versa, this is a good time to give it a plug:

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.

Compare the Toyota hybrid system to a modern diesel auto - which is the closest thing in terms of fuel economy and driving experience.
The Toyota system adds the following:
- Traction battery
- 2 motor/generators (MG1 and MG2)
- DC/DC converter
- Turbo assembly (MG1/MG2 provide performance boost)
- DPF (it's petrol not diesel)
- DMF
- Alternator (battery is charged by MG1/MG2 acting as generator)
- Starter motor (MG1 does this)
- Transmission (engine/MG1/MG2 are permanently connected through the power split device)
- Drive belt plus pulleys etc. (all ancillaries are electrically powered)
- Starter battery (traction battery does this)
- All the cabling, pipework and sensors associated with the above

Q: Are hybrids economical? I see, for example an IS300h doing 35mpg and wonder how much extra is electric? Any? Or is it just not measured? Would it be doing 50mpg overall when elec is taken into consideration? I can see the plug in feature being useful but without that...
The IS300H is not a plug in hybrid - all the energy to run the car comes from the petrol in the tank. Where do you see one doing 35mpg? Most databases seem to have them mid 40's to low 50's mpg. Lowtimer said:

Ta for posting that! Very interesting to poke about with, and led me to this one:

which explains the hybrid gubbins really well.
