    IS300h - mpg question

    I kept being told that be a friend who had a 520 bmw of the same age as my 300h. So for a bit of fun, and to shut him up! We reset both computers and ran up the M5 for 50 miles, both keeping to the same speed and where possible both using cruise. I was 57.8mpg, he was 59.2mpg, the difference was so insignificant that he now accepts that the 300h may be suitable for motorways and urban Sent from my iPhone using Tapatalk

    IS300h - mpg question

    When the 12v starts to get old they draw more and more frequently from the hybrid battery. It’s a gradual thing, but eventually you get to a point where you notice it. On the prius we used to get about 7 years out of a 12v battery, given that the oldest 300h’s are 2013 it’s something we may start to see soon Sent from my iPhone using Tapatalk

    IS300h - mpg question

    Yes, it’s fair to say that the computer does read optimistically. However with hybrids there are also other factors that will affect your fuel consumption, tyre pressures being the most common, the state of the 12 V battery being another and finally the operating temperature of the hybrid battery and the state of the cooling fan for that. Last year my fuel consumption started to drop off quite badly, it transpires that the vents by the back seat was being blocked off and so the battery was running out of its optimal temperature range Sent from my iPhone using Tapatalk

    IS300h - mpg question

    Mine is the SE spec with 16” wheels so that may be part of the reason I get quite good economy. After 35 miles of round town driving That will drop off now as the traffic is building up and I’m more stop start now Sent from my iPhone using Tapatalk

    IS300h - mpg question

    I use mine as a taxi so it spends the vast majority of its time in town. I average between 48-52 most days, I’m not a slow driver but I’m not afraid to stick my toe down when the need arises. On a run up to London I will easily see 55mpg, I sit at 75 and run it on cruise most of the time. Sent from my iPhone using Tapatalk
  6. Yep, that worked for me, nice and simple [emoji1303] Sent from my iPhone using Tapatalk

    Residual values

    Hi Nigel, I do patient transport primarily now but also a few school runs. A lot of my work is city to city journeys. I’m generally out in the road 5 days a week 8-10 hours a day. It’s a nice comfy place to be and my passengers love the Lexus as well Sent from my iPhone using Tapatalk

    Residual values

    I bought my 2014 IS300h SE in May with 59,000 on the clock and paid £13,500 for it, less than half its original retail price. I never buy new, the loss is too much for me to absorb, I always buy good one owner cars that have been well looked after, I keep them for 2/2.5 years or when they reach 200k, whichever comes first (recently it’s been the 200k) at which point it will be worth very little sadly. It will still have fsh and been in as good condition as I can keep it though Sent from my iPhone using Tapatalk

    Advice on IS300h remap?

    Remaps do release better fuel economy with diesels especially, however this technology doesn’t benefit hybrids I average 47-51mpg out of my IS300h and given the size of it I’m pretty happy with that, I have seen late 50’s and even early 60’s on king runs but that was in the summer when the weather is better, sounds weird but that does have an effect of the fuel economy.

  10. mine only works when a destination has been set, it only advises me of upcoming junctions.

    Hybrid battery error message

    Just an update on this. It’s now been 4 weeks and there is a noticeable improvement in both mpg and battery state of charge. It holds its charge a lot better and I am back to seeing over 50mpg daily on it now. Sent from my iPhone using Tapatalk

    Reverse lamps

    I found this made a massive difference, I have to reverse into a pitch black drive and now it’s so much easier Sent from my iPhone using Tapatalk
  13. And don’t forget that HID bulbs have ballast packs that are very high voltage Sent from my iPhone using Tapatalk
  14. Yes bulbs can be replaced, but I don’t believe you can upgrade hid bulbs. Sent from my iPhone using Tapatalk
  15. I don’t believe you can get updated hid bulbs, however someone more knowledgeable may be able to confirm that Sent from my iPhone using Tapatalk
