Have I got this right. Honda have remapped the 2022/2023 models so they are smoother to drive ,quicker, quieter and recharges quicker. All wins surely? Mapping (tuning characteristics such as timing, fuel mix etc,and maybe the loading on the recharging generator) is always a compromise on performance,fuel consumption, smooth running etc. And in this case the compromise may be that it sounds like 'a bag of spanners' on low load tickover , at least compared to the tickover sound of a 2020/2021 model. (which are presumably less smooth, slower and noisier on the move ,although I'm more than happy with mine as it is , knowing no better) )
A characteristic of the hybrid is that its often in EV mode and silent when stationary.If they now recharge quicker when the engine is running it may be in totally silent EV mode even more often.
Honda may well have concluded that improved road performance is more important to customers than tickover being as quiet as possible but at the expense of other performance. First time buyers of the technology will be none the wiser and accept the noise as being 'a characteristic of the vehicle'. Its only second time buyers who notice the difference, and not like it.
Not having driven the latest cars I am in no position to comment on bags of spanners noise, or whether the improved performance justifies it. And whats acceptable to you may be a personal choice. I may be more tolerant here than most as my previous car was a diesel
But i suspect you can have one thing or the other, not both.
I think dealerships and Honda are in a bit of an awkward position. They can hear the engine is noisier, and cannot deny it to customers, but they know its not a fault as such , it is indeed now a 'characteristic of the car'. They can check there isnt something amiss thats causing extra noise, but if they dont find anything then the car indeed doesnt have a fault. Its possible in the future they might decide to remapp to a better compromise . But then they may face the wrath of 2023/2024 buyers complaining its not as good on the road as their 2022/2023 one was.
I now know, if I replace my Jazz with a newer one, its probably best to take one for a test drive first.
