Was it a mistake for Honda to use the term e-CVT?

At fear of getting crucified by ZZJA again, :'(
As an experience CVT owner. I would agree. Most reviewers say it has a CVT gearbox which is a total misnomer as it is NOT a gearbox. It is a lock up clutch. The engine has no way of changing gear ratios, it is simply locked directly to the transmission and thence to the driven wheels and the noise is caused by it simply revving (eventually) to it rev limit.

Not quite correct.
The engine is only locked directly to the transmission, during cruising or low power conditions.(above circa 45mph)
If max power is required, maybe to overtake another car or whatever, then the lock drops out and the transmission reverts to petrol/electric operation. whereby the engine does need to rev, generate the required energy to power the drive motor.
I believe this is what the so called experts journalists are concerned about.
However in my view that noise is far less than a conventional CVT gearbox and without doubt the MK4 Jazz is the best Jazz yet.

Apologies, I forgot to mention the speed and or requirement of more 'oomph'.
I was somewhat sidetracked when I posted this.

That's probably it then.

I have a light right foot and accelerate slowly and smoothly along the on ramp so I can blend in when joining motorways.

Me too when I can. But recently I've had a couple where the on ramp from roundabout to carriageway was very short and I needed to give it some welly to merge safely . The car delivers, albeit with a bit more noise for a short time.

I think the very nature of this car encourages a smooth approach. That does not mean "Sunday driver" slow, but there's something quite satisfying about the way it's been engineered. It also feels very solidly built, with the exception of the bonnet (which seems to be about 2kg total weight ).

I think they should have gone with 'hybrid EV' or something similar. Not many reviewers understand the petrol generator and the one speed cruising lock up clutched direct drive.

According to the Dartford Crossing, it's a plain CVT car:

JAZZ EX I-MMD CVT

is what comes up after I put my registration in.

There are several sections of road where I have to accelerate up to 70mph briskly in fairly heavy traffic, so I have experienced the 'gear changes' when doing so. They don't usually happen at other times though.

They did. That's why they call it "e:HEV". It's other 3rd parties who call it something different.

I tested this earlier this evening. I was driving in town and despite accelerating hard to the local limit I detected no pseudo gear changes. I'm sure I have heard the gear change sounds though; I reckon it must have been when the car was accelerating hard up to motorway speeds.

I'm not sure that Honda themselves actually use the term "e-CVT" do they? The only place I see that is in magazine reviews and other secondary sources where the author may well have invented the term because they can't get their head around how the hybrid system works. For example ...

Honda themselves, on the Jazz website, use the term "e:HEV"...
https://www.honda.co.uk/cars/new/jazz-hybrid/overview.html
Can't see any mention of "CVT" in there anywhere.

Honda themselves DO use the term "eCVT": https://www.honda.co.uk/cars/new/jazz-hybrid/specification.html

Start with an engine - 

i-MMD eCVT

Petrol / Electric

I remember those horrid little DAF cars that had a CVT transmission. It was done with a belt between conical pullies that moved apart or together to change the drive ratio. If anyone thinks that Honda have made something similar with their CVT they may be scared off.

This is an interesting insight into the scale of the Global CVT Transmission market.

Perhaps, in other markets, e-CVT has value.

So they do. However that’s only in one or two places, the rest of the website uses the e-HEV branding extensively; it seems clear that’s how Honda want to refer to it.

Sorry about that. I never drove one; they may have been good cars, after all, Volvo carried on using the variomatic transmission when they bought the company.

Maybe a MY22 tweak ?

Why introduce fake gear changes when a smooth single gear works OK

[Jayt43]

I thought you had insider knowledge about MY22 "tweaks" Kremmen? Is this a hint?

[Kremmen]

I have no idea what the tweaks actually are.

All I know is that the MY22 had some software/firmware tweaks.

My source knows I'm here so has quite rightly kept what Honda want to keep confidential under their hat.
