    Amazed with the 300H

    Hope you are able to get the car you want soon - I'm sure you will enjoy it and won't be disappointed.

    Amazed with the 300H

    Linas - you seem like an angry person - really don't know why - I was trying to be constructive. The comment about the Autobahns came from some of my colleagues on the continent - appreciate some of it may have been skewed a little in translation but the crux is that if a driver is involved in an accident on the Autobahn when exceeding the advisory speed limit, the burden of proof that their high speed did not cause damage is with the driver exceeding the recommended speed limit. It may not be a criminal offence but money, or at least insurance money, talks. However that is taken on board it has had the effect of lowering (or capping) the speed of many drivers on the Autobahn. I do agree though that the German drivers have much better lane discipline than in the UK and that is one of the reasons I enjoy driving in Germany. Your comment about needing to drive an IS 300h carefully and slowly like a pensioner is just insulting! Any car regardless of power in the wrong hands can be driven at an inappropriate speed, in an inappropriate way, and becomes a lethal weapon. I have NEVER had a problem with my brain just telling me to slow down or not overtake because the car is "slow" - do I overtake in the same way as in other cars I have had - YES! and use the appropriate control modes to do so - safely. Do I take stupid risks - NO - but I never have and I try and respect all the other drivers on the road, despite some of them being complete idiots! Do I enjoy driving the car - YES! and in fact more than most other cars I have owned. As I said, to appreciate the IS 300h and what it delivers I do think it takes a few months of ownership and not just a few hours or even a day - but after that first few months it certainly didn't change the way I drive or how I perceive and react to situations, just allowed me to appreciate the depth of the car and its technology more. I certainly don't think the car is for everyone but no one is twisting anyone's arm to buy one either - there are many, many cars all offering different experiences and waiting for someone open their wallet and buy them. It sounds like you want the reliability and quality of a Lexus but something that goes from 0-60 in sub 5 seconds - well there are plenty of alternatives out there for you to try - including the Lexus LC of course - assuming you have the money to scratch the itch - I've been lucky enough to scratch a few of my own itches in my life. No manufacturer will ever make the perfect car for an individual - that's why some people have more than one of course - but in general a very high proportion of owners on this particular IS Mk III forum seem happy with their choice, the reasons for which I am sure are many and varied (300h and the 250 or 200t). The few who have actually owned an IS 300h for a reasonable period of time and found it doesn't suit them, then I take on board their critical comments that come from that experience and wish them all the best with their new purchases - one day that might also be me should my needs and circumstances change, as they do through life. I have seen your similar comments slating the performance and power delivery of the IS 300h in a number of previous posts - you seem to be a pretty lonely voice - but everyone to their views and if that is your view then fine - we will agree to disagree. I am happy in my choice of car, I assume you are still looking for yours. That's my final word on the matter, though I am sure you will want to have the last word?

    Amazed with the 300H

    So totally agree with all of the above and mirrors my experience. I have had a number of fast and expensive cars in my time (the cream of the crop according to the motoring journalists) and also many hire cars in the UK, Europe and the USA. In addition to many hundreds of thousands of miles driven in the UK I have also driven many times across much of Europe - a lot of that on the German Autobahns where I have in the past used performance to the full - however in more recent years I have found even on the Autobahns that the majority of the local population now drive a "sensible" speed (usually around 90-100mph) - which may be due to a change in their law where if you drive over the recommended speed limit (in unrestricted parts 130km/h) you could be held accountable for a crash, even if it was not your fault - which could lead to serious problems with the law and with insurance companies - so 125mph for the IS 300h (where it's not in the least strained, as it's just electronically limited, is plenty). I do think that it takes some time to "get" the IS 300h - this is where the car suffers at the hand of journalists and those who just get one as a courtesy car for a day when theirs is in for a service for example. When I was looking for my next car I went back and forth over the IS and in the end managed to get one for a full day test drive. I tried to mimic my usual driving and conditions the best I could in that time and by the end felt good about buying the car. However, I have to say it took me a few months to then really "get" the experience. In real world day-to-day driving (i.e. a mix of roads, some where progress can be made but others with traffic jams and interminable road works...!) it delivers everything I want. And it's certainly not just a "city car" (though excellent at that) - long motorway drives (of which I do a lot too) are very enjoyable, almost serene, and I arrive at the other end as refreshed and calm as any other car I have been in - and no later than any other car I could have been driving regardless of on-paper performance figures - and with petrol consumption generally between 48-52mpg to boot. It is the balance of doing so much so well in such an unflustered way that puts the IS 300h up there as probably my best overall car.

    The "slow" comment is very relative - on paper the IS 300h doesn't look all that quick on the standard 0-60mph (62mph) but rest assured that this is misleading in the real world. Put the car into Sports mode and pedal to the metal and the manner in which the power flows through the drivetrain makes it deceptively quick - there are no gear changes to be made and no let up in the "push". In particular the performance from around 40mph to ...ahem... very fast is more than enough for the real world, and all undertaken with a certain calm which means keeping a close eye open for when you reach the legal speed limits. I have driven numerous "faster" cars (on paper) and you do get a different perception of speed in those cars - even with an auto-box - as the shifts are noticeable sort of creating the milestones in the mind of speed and very often undertaken in a much noisier manner, again adding to the sense of speed. My last "fast" car was a BMW 330i (2006) with an auto-box and which was no slouch - I wasn't sure how the IS 300h would compare being slower on paper but I have to say the difference has not been any issue to me - the IS 300h just delivers in a different way that takes a few thousand miles to get used to and appreciate.

    Firm accelerator peddle

    Here is the video in the US about the Toyota sticky throttle pedal:

    Firm accelerator peddle

    Thought it was all drive by wire now - so the accelerator pedal has no mechanical linkages at all - it just relays the pedal position to the computer which decides what power to apply for any given circumstance. Perhaps the pedal pivot needs a bit of lubrication?

    MPG on IS 300h etc.

    I came to the IS 300h from a long line of BMWs - my last one being a 330i. Much as the 330i was a good drivers car with - a) constant roadworks on the motorways b) permanently congested A and B roads c) proliferation of ridiculously low speed limits enforced by an ever increasing number of fixed, mobile, average cameras d) the crumbling road network, e) increasing fuel prices and stupid VED decisions - after a day's test drive I was sold on the IS 300h. For this real world day to day driving the car and it's hybrid drive train really deliver. In fact I now look forward to driving again as the car is to me a perfect fit for what I have to face each day I go anywhere. I live in the South East and I can see if you live in a more remote part of the country there may be other factors but I wouldn't hesitate buying another IS 300h. A friend has a BMW 335d - very quick but in comparison sounds like a tractor and does not deliver the relaxing experience of the IS 300h in the cut and thrust of modern congested roads.

    MPG on IS 300h etc.

    Not sure what settings you use but I have a 300h Executive and on long motorway journeys average between 48 and 52 (measured by the on board computer) depending on traffic and temperature - when a clear motorway that's not hanging around either. I generally leave mine in Eco on the motorway and use cruise control a lot (as there is little need for blasting it around). If I drop speed to just below 70mph then can push towards 55mpg on a temperate day. I have tried driving for a while in Sport and noticed quite a drop in mpg even driving the same speed/way and even in Normal mpg is definitely down a bit on Eco. So I tend to opt for Eco for long runs.

    Wheel bearing noise

    Glad you got it sorted - issues with tyres wearing oddly etc. and alignment can cause so many worrying noises and vibrations - certainly some chunks missing like that was most likely the cause of the noise you heard more than the alignment
  10. wharfhouse

    Wheel bearing noise

    Had something similar on a previous car with a noise from the rear that sounded like wheel bearings. The alignment was out at the rear which has caused the tyres to wear in a such a way that it produced the noise which was just related to the speed of the wheels on the road - couldn't tell easily from the tread wear that there was anything untoward but had it checked on a full four wheel alignment and it was out by quite a bit - had it corrected and new tyres put on and the problem never came back.

    MOT Failure

    The £27 is (according to my Lexus dealer) the discounted MOT price with a service plan in place - when I took mine for a service and MOT I wasn't on a service plan but discussed this with the service department and decided to sign-up to cover future servicing. As I decided to sign up to a service plan going forwards (although paying on the day for the current service and MOT) they discounted that current MOT to the same £27 as if I had a service plan in place.

    Front sensors sensing!

    Had this happen to me for the first time today. Sat at traffic lights and was at the front of the queue so nothing in front of me. Pouring down with rain and suddenly the front parking sensors (centre ones) went off much to my amazement and that of my passenger - just as if I was approaching a wall! As soon as I set off they stopped and didn't have the problem from there on. I put it down to rain running down over the sensors.
  13. Haven't tried super unleaded in my 300h but in my previous BMW (3.0 litre petrol) when I used it I found two things: 1. The engine was a tad quieter and smoother - however I have found this can also happen between different petrol suppliers anyway - but the super unleaded always delivered this 2. The petrol consumption was on average about 5% better over a tankful on super unleaded (based on using the same petrol provider and petrol station) - appreciate that this is difficult to measure accurately given the constant changes in real world driving but I did the comparison quite a number of times on the same long runs so I am pretty sure that I was seeing a small increase. However, given the increased cost of super unleaded then I would say any cost benefits were awash 3. There may have been a slight gain in performance on super unleaded - I never actually measured this so it was only perceived and again very negligible, if at all, and may well be linked to the engine running a bit quieter / smoother I ran the previous BMW on super unleaded pretty much constantly however - not for any financial gain but it just seemed to run slightly better. Haven't bothered with the 300h though as it seems to run so smoothly and quietly on regular unleaded anyway!
  14. I agree that there would probably have been some engine regen as well as I coasted down from motorway speeds and into the slip road and braked up to the roundabout but there was no doubt about how the algorithms chose not to use the ICE to recharge the battery back to where it was before a good half of it was used on the incline, but then within that coasting down it jumped from one-third to one-half ready to be used again and then jumped to it's usual 80% very quickly as I went into the stop start of the A roads. My point was that the algorithms are IMO a lot more involved that simply depleting and recharging the battery - if that was the case they would have just used the ICE to recharge the battery again during the 10 miles I covered after the incline, but it didn't - the system waited until I was coasting down to a stop and there must have been some logic in that. From the experience I had (and could see on the battery level display) the algorithms would appear take into account what you are doing and appear to try and predict (yes I know they can't truly know but can probably make a good guess based on a set of circumstances) what you then might be doing next to maximise efficiency and decide how to most effectively recharge the battery again. However, unless we have access to the source code I doubt we will ever find out fully!
  15. Although I agree about the hybrid allowing the engine to run the Atkinson cycle and so be more efficient while electric power fills in the torque needed at low revs that the Atkinson cycle doesn't deliver I do think we perhaps don't give the clever people at Toyota/Lexus the credit they deserve as the thinking they employ in the algorithms seems to go deeper than this. This week I was intrigued to watch how my IS 300h used it's battery on the motorway. I started out at the bottom of a long steady motorway incline with pretty much a full battery. The display then showed that while going up the incline the car was using both ICE supplemented by electric all the way up the incline. By the time we reached the top and it levelled out then the battery was down to about one-third full. The interesting thing was at this point I expected the ICE to recharge the battery, but it didn't. The car maintained the battery at about one-third from then on - using ICE and electric on and off - the way it mixes ICE to driving wheels, ICE to battery and electric to driving wheel varies constantly. My run was on a fairly empty motorway so I was maintaining a steady speed for a probably another 10 miles and the battery stayed at the one-third full for all that time. Inevitably I then came to leave the motorway and started coasting to slow down - the car went into regen and the battery started topping up quickly reaching half full and then on leaving the motorway and having to use the brakes more and the ICE to accelerate along the first mile of A roads the battery was topped up to it's near full state. So, from the above the car isn't simply depleting the battery and recharging it using the ICE to full again while on the motorway but appears to wait to recharge to make the most use of regen charging even when that wait is for a long time. I had noticed this before but never really watched it as closely as I did this time. I am sure that Toyota/Lexus employ some of the best engineers and mathematicians to calculate the very best way to maximise the overall efficiency of their hybrid system and IMHO the algorithms they develop are actually a lot more sophisticated than we often give them credit for.
