  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.
