Under the bonnet of the Honda Jazz: I-SHIFT, VTEC and more technology

Technical information and a behind-the-scenes interview with Kohei Hitomi - the man challenged to design the new Jazz - and Elliot Smith (Technical Trainer).
Partial transcript:
"What makes the Jazz great is that it's outstanding in not just several areas but in areas that typically conflict: design, usability, handling, economy. The exterior styling concept was originally created by Okamoto-san who designed the Civic.
It is a very advanced design - what we wanted for Jazz. One target customer is downsizers from the C-segment. We designed the Jazz so that they would feel good about its quality and ride comfort."
Elliot Smith (Technical Trainer): "We did some subtle changes to the suspension as well. There's basically the same suspension layout - to the front, we've increased the castor which gives a bit more trail - this gives a more positive feel to the steering. It gives a bit more weight to it as well.
We counteracted that with electronic power steering - we've raised it from 40 amps to 60 amps. The rear suspension, we changed the ratio where the spring lies - this gives us a more supple suspension ride, but a firmer and better feel overall, so the car handles a lot better but gives you a much more nimble feel.
With the new Jazz, we introduced two engine variants, both with VTEC. We've gone from two valves per cylinder to four valves per cyclinder. This gives us the best of both worlds with economy and power. For 1.2 L, we have 90 PS, and for 1.4 L it's 100 PS.
For the first time with Jazz we've introduced I-SHIFT. This is an electronic gearbox which operates the clutch and the gear changes for you. So you can either drive in automatic mode - same as an automatic gearbox - or in manual shift mode. Manual shift mode you can either operate through the gear lever or the paddle shifts."

too bad the rest of the world does not get i-shift

stay away from ishift ! go for CVT for your own good...

[@ikomu8907]

@@albertoroman5960 CVT gearbox is much more reliable than ishift hence after the massive drop on Sales Honda stopped iShift and gone back to CVT again ...

mu you are a gentleman.

Too bad? i-Shift is an absolutely terrible system..the only reason they changed from CVT to i-Shift was to save money.(they later realised and returned back to CVT in newer models of Jazz and Civic).
It’s one of the worst transmissions ever made.hesitant,jerky,slow and can even be dangerous.

To save money,Honda changed the reliable CVT automatic gearbox to the awful,jerky and hesitant i-Shift for European market (including UK) 👎👎

The music is terrible on this video

One of the worst gearboxes ever made

ishit the shift is so slow it's like they created it for a joke or something lol if you actually bought this instead of the manual after testing both unless you have a medical reason for it something must have been wrong with your brain.
