  1. No gearbox can improve efficiency. The definition of efficiency is "what you get out, divided by what you put in". Any kind of gearbox will create losses of energy and therefore reduce what you get out from the system. i.e. it must reduce the efficiency of the system.
  2. My Gen 3 also had sideways facing sensors that were used for the "self parking" facility. I believe it was these sensors that generated the information that fed the dynamic route lines that showed on the display.

    Thanks Anita - it sounds like they are just in very short supply.

    I popped in to the local Hyundai dealer on the way home today in the hope of getting a look at the Ionic Electric. I was surprised to be told that it will not be available until May or June. They have no stock and no demonstration car. I told the dealer that you were already driving one and he expressed extreme surprise. I wonder what is going on?
  5. Pete - do you have an authoritative source that says the PiP charges the 12v battery when the car is plugged in? I've never been able to find one. Various comments in the handbook lead me to infer that the 12v battery does not charge when the car is plugged in. But I cannot find any direct statement in the handbook so I readily admit that I may be drawing the wrong implication. The two handbook statements that I find telling are: "The 12-volt battery recharges automatically while the hybrid system is operating" "Confirm the following before charging (i.e. charging the traction battery) - The POWER switch is OFF" With the power switch off, the hybrid system is not operating and therefore I infer from the first handbook statement above that the 12v battery is not recharging. My own experience in running the car seems to confirm this. I have on several occasions found a low state of charge in the 12v battery after doing a full charge of the traction battery.
  6. I'm a low mileage user and I keep a similar device in the car. I also make a habit of sticking a trickle charger on the car once a week.
  7. I'm not sure whether you really meant to say that . . . . . I have been driving automatics since the early 1970's and have driven autos by several manufacturers, both European and Japanese. Mostly, the gear boxes had a series of ratios (just like a manual box) with some mechanism for changing gear at appropriate engine/road speeds. I once drove a Daf with a continuously variable box but it was very basic compared with the Prius drive system and really struggled with hills. All the other boxes were necessarily "steppy" and several of them changed gear with a noticeably jolt especially when using the "kick down" facility. Some of them were very unreliable. I bought an automatic Austin Maxi in about 1973 and kept it for only a year, during which time the gearbox was changed twice. By comparison, the Prius drive mechanism is entirely smooth and without any steps. In essence it has only one gear ratio which it does not change. The change in ratio between ICE speed and road wheel speed is achieved by a differential speed mechanism within the sun and planet gears on the transaxle. Changing from a standard auto box to the Prius eCVT is a revelation. It is simpler to drive and is a large contributor to the relaxed driving style that is possible in this vehicle.
  8. That's not an unusual range prediction on mine. I don't think that I have ever seen a prediction of more than 12 miles. Remember that this is not an absolute figure. It is based upon the way that the car has been driven and uses a figure based upon what has actually been achieved. So if you accelerate hard and drive at the top end of the EV speed range you will get less miles for each unit of electricity and the next time you charge it the range prediction will reflect that level of efficiency. I often arrive home with some "electrical miles" remaining, having already done more miles that were predicted at the start of the journey. But conversely, I often run out of "electrical miles" before reaching the predicted range. It all depends upon the terrain and the driving style.
  9. My compliments for a nice series of pictures. They are very good.
  10. Mine certainly didn't. It had 15" alloys with 195/65R15 and full wheel cover. No spare wheel of any kind. I have a copy of the Prius Plug-in sales brochure printed in July 2012 and it specifies under Tyres and Wheels:- 15" alloy (195/65R15) with full wheel cover. Tyre repair kit Either they have made a mistake or there have been some additions/modifications. If they really do have skinnies, I would be interested to know where they are stored.
  11. Here, Here. Thanks Jay for an excellent review. An enjoyable read and very helpful. I would be interested to hear more when you have had the chance to drive the Lexus on snow or icy roads. I owned an IS250 for three years and it was a lovely motor and a joy to drive, except on snow and ice when it became an absolute pig. Lots of power, an automatic gearbox, rear wheel drive and no limited slip differential. It was just a very bad recipe for driving on slippery surfaces. The Lexus followed two Nissan Maximas and a 3 litre Camry each of which had front wheel drive and all of which were easy to control on snow and ice. My first Prius was part of a plan to get back to front wheel drive and I was very pleased with it in that regard.
  12. I'm with Barry. I've been with my Toyota dealer for many years and would say the staff there are both helpful and sensible, nevertheless the company system would not allow them to sell me a skinny spare. I tried lots of other Toyota sources in the UK without success and eventually got one from a very large taxi firm in Germany that services its own vehicles and sources it's own spares directly from corporate Toyota.
  13. Mine is just to the left of the mirror and I've never had any complaints from passengers. If you have a removable memory card, getting at it affects consideration of the positioning of the camera.
  14. Haven't had any occasion recently to use the demist switch, but I have been running the car with the air-con on and (at low speed certainly) the battery copes with all that load. Yesterday I did a seven mile out-and-home trip with external temperature of 30 degrees showing and the internal temperature set to 19 degrees. Air-con blasting away to keep things cool. No ICE and an indicated 999 mpg when I got home.
  15. I have seen it do it, but I wouldn't swear that it always does it - my observation isn't that good. The engine occasionally switches on when I really don't expect it to. A few weeks ago, on my way home from a local trip, with the car warmed up and plenty of electrical miles left, I stopped at a red light. The engine switched on and ran for the whole period that I was stationary and didn't switch off until some time after I was in motion again. The car went in for a service a few days later and I mentioned this strange behaviour. They did all the appropriate diagnostic checks but found nothing wrong.
  16. Boiling kettles and doing extrapolations is interesting, but the figures in the quote above are real figures taken directly from charging a PiP. The charger in my garage measures and displays the amount of energy used in charging the vehicle battery. I have a record of every kWh that I have put into the battery and what it cost. I also have a record of every litre of petrol that I have put into the car and what it cost. The total of those two figures and the total number of miles that I have done in the car gives the figure of just over 6p per mile that I have quoted. I mentioned the nature of the journeys that I do, because the efficiency of the PiP is affected hugely by the proportion of the total mileage that is done on the battery alone.
  17. I've never charged my PiP other than at home - it's just not practical. A full charge is not more than 3.5 kWh and at home that costs me less than 36p (I pay 10.268p per kWh for my electricity) Given the nature of the journeys that I do my total fuel costs are just over 6p per mile so, £5 will take me more than 80 miles. £5 to put in 3.5 kWh will give me less than 15 miles so it's a long way from being a bargain. I agree with johalareewi; this is to discourage the slow chargers.
  18. Nice example of it's uselessness this morning - email from Toyota inviting me to go into "MyToyota" diary to see when my tax is due.
  19. All my experience with Toyota software has been uniformly bad. Last week I had my car serviced and was asked whether I had registered my vehicle on "My Toyota". I said that I had, but that I never used it because it was so ponderous and generally more trouble than it was worth. Does anyone actually make use of it? Is there anything it provides that you can't get in a fraction of the time from a simple, self-designed spread sheet?
  20. A heat pump is like a refrigerator. It has a closed circuit filled with refrigerant that vapourises and condenses in absorbing heat in one location and giving up the heat in another location. During the vapourised phase the refrigerant is in the form of a gas. If that is the gas that they are talking of injecting then it has nothing to do with petrol.
  21. Originally the leading character in H Rider Haggard's novel "She", but probably made more famous by John Mortimer in "Rumpole of the Bailey" where Rumpole regularly refers to his wife as "she who must be obeyed".
  22. For individuals of a particular height there are considerable variations in the distance from the hips to the top of the head. In days gone bye, a colleague and I were exactly the same height when standing (i.e. six feet and one inch) but he was four inches shorter than I when we were sitting down. It created opportunities for mischief when we visited car showrooms together. He sat in the drivers seat and complained that he couldn't get his knees under the steering wheel, while I sat in the rear and complained about the lack of head-room. People are too variable to be useful as gauges. You need to get the relevant dimensions for the two vehicles and compare them.
  23. When a "respectable" car magazine makes such an inane remark, it really does make you wonder.
  24. My 2009 gen3 T Spirit came with 17" wheels fitted with Michelin Pilot Primacy tyres. 215/45 R17 87W front and rear. They were very good summer tyres but pretty awful in the winter. I recall that the handbook recommended a change of tyres for the winter. You might like to investigate Michelin Cross Climate for all year round use. I have them on my PiP and they work well for me, but I have 15 inch wheels.
  25. I long ago gave up on the Prius satnav and bought myself a TomTom with lifelong map updates, lifelong safety camera data and the capability to notify local changes in speed limits, camera positions etc. In consequence I have maps that are very up-to-date and I receive almost daily, updates of mapping data, that load easily and quickly. I would love a built in satnav that works, but the aftermarket devices have left the Prius stuff so far behind that there is just no point in staying with it.
