there were no changes to the CVT system.
I believe all Jazz Hybrids were made in Japan, just like the Insight. Swindon does produce Jazz manuals and CVTs but not the hybrid. One source claims even the regular CVT is Japanese.
Honda UK Jazz Press Kit says this:
The Jazz petrol models will be built at Honda’s manufacturing plant in Swindon alongside the Civic and CR-V while the hybrid variant will be produced in the Suzuka factory in Japan.
I know the Jazz Hybrid well - I wanted to buy one but got a sharp deal on a used but almost new Insight.
My dad did buy a Jazz Hybrid later on and so did my neighbor. It is an ideal car for pensioners; both in operation and access. My neighbor can carry his wife's folding wheelchair in the boot.
The engine, CVT and suspension etc. are said to be identical with the Insight; the Jazz has more leg room as the seats are higher.
The Jazz does feel more lively; more than only the weight difference can explain. As if it is 150 kilos lighter, not the actual 40.
I suspect the engine is tuned for more power.
If you think your Insight is fun to drive don't set foot aboard a Jazz IMA
The interior is different as the whole body is different, also some parts and displays were designed differently. The lay-out matches close to the Insight though and functionally it is identical.
I still cannot get why Honda decided not to export the Honda Fit Shuttle Hybrid
That would have easily outsold all other Honda hybrids combined in Holland. It would have hurt Prius sales quite some.
