Not enough for me to buy anything with a CVT still.

Informative, thanks. The one forte of the Toyota CVT is uber reliability. I would have doubts that this "improved " system is to the detriment of that (it tends to be a side effect of complicated improvements )

I would be interested in buying a car with this system down the road, but I might let others put up thousands of miles in their own cars first-never a fan of being a guinea-pig!

Agreed, my gut reaction is to avoid new technology till they've ironed out a problem. Another reason why I tend to buy late-build of an older generation rather than the first of the new gen. Car makers make so many incremental changes/improvements to models throughout the production cycle, many of which are so minimal they'll only be noticed by enthusiasts.

Here's the description for anyone who can't see the video:

"People are often underwhelmed with the driving experience of a CVT, and initially, many CVTs were underwhelming. Toyota is changing that, with numerous improvements to their CVT to make shifts quicker, more precise, and more engaging to drive. And it's no longer just using a belt for accelerating. Starting from a stop, the CVT switches over to a direct gear drive, much like starting in first gear in a manual transmission. As the vehicle speed increases, the first gear is dropped and it switches over to belt drive, letting the CVT handle the higher speeds.

The changes to their new continuously variable transmission result in better launch acceleration, faster shift speeds, and a greater transmission efficiency at all vehicle speeds."

I wonder if this will make any difference to the thing that puts me off hybrids with CVT: the frenetic revving that happens if you need some quick acceleration, such as when joining a motorway.

Avant, that has nothing to do with it being a CVT, it is because of where the power band of the engine is. As hybrids have N/A petrol engines, having a 'launch gear' is going to make no difference to the engine speed peak torque is delivered.

madf, i don't actually bother with sport mode on out current shape jazz CVT, i have found that it does not make any difference to the burst of acceleration needed to pass another vehicle or join a motorway. As long as the throttle is fully depressed (passed the point near the bottom where there is a bit more resistance!), it will go right to the red line in the normal 'drive' mode. But i agree, it does sound suitably rorty!.

Re Toyota CVT - This is not how the hybrid Toyota eCVT works. Instead this is an electronically controlled transmition with two integrated motors (/generator). Surprisingly few moving parts:-

What's wrong with them? I've never used one in a car but I've met somebody who bought a Prius mainly because he loves the CVT and it's so much better to drive.

I've had scooters with CVT and think they're brilliant, always have good torque and never in the wrong gear. Only minor issue is that they weren't as smooth as a manual when pulling away but these were cheap machines, I suspect cars would be better.

My CVT Jazz has seamless changes which are unnoticeable. As it has a torque covertor couple to a CVT (2012 on models only), standing starts have zero judder.

Even a senile old dodderer like me can drive it smoothly - and faster than 30mph......:-)

What is actually happening is you plant your foot on the accelerator, the revs shoot up to 5000 and you don't really accelerate at all. But since the engine is making such a racket you think you are.

Exactly the reason I hate all CVT's.

"What is actually happening is you plant your foot on the accelerator, the revs shoot up to 5000 and you don't really accelerate at all. But since the engine is making such a racket you think you are."

Yes, quite!, and i'm sure you think my speedometer is lying when it says i am now doing 70mph when a few seconds ago i was doing 50mph. In fact, i must have imagined overtaking that articulated truck on a short straight the other day, as according to you it is not actually possible for a CVT equipped car to actually pass anything.

Blah, blah, blah, (yawn)

You do accelerate, often more rapidly than in a manual equivalent. However they are a bit unrefined as they immodestly race up to near maximum revs and stay there while the car catches up. Driven modestly they’re fine and tend to be very efficient and today they’re generally trouble free especially Toyota’s.

I remember the early versions with particular hatred directed at the Volvo 340 which was God awful. Ford and Fiat CVT’s from the 80’s and 90’s are worthy of special note too. Jerky and noisy in operation with zero transmission creep to allow safe parking they were usually bought by the very people who were least able to drive them well.

The first good CVT I ever drove was (believe it or not) a Rover Metro 1.4S which was an absolute hoot. Went like a stabbed rat around town, offered economy to match the manual cars and never gave us any trouble. Shame they never rust proofed them properly. Today’s CVT’s are a lightyear ahead of what they were.

My Dad used to have a Daf 55 marathon (circa 1972), and while I can't remember how it felt from the back seat as a 6 year old, he always says that it was a great little car to drive. It was very smooth and comfortable, and a bonus from its idiosyncratic layout (each rear wheel had it's own drive belt) meant it had great traction pulling away in slippery conditions. It could also, in theory, hit its top speed going forward or backwards!.

So just had a look at various road tests

30-70 Jazz CVT 13.5 seconds.

30-70 (through the gears) Skoda Fabia 1.0 TSi 8.9 seconds

Which is quicker?

But some don't like changing gear so for those Skoda Fabia 30-70 in 4th 12.5 seconds

Use the gears and the Fabia is much quicker, be idle and leave it in 4th and its still quicker. I rest my case.

But just spotted the What Car review of the latest Jazz (which must be the best?) They say "If possible, you should avoid the CVT automatic gearbox. It allows the Jazz’s engine to rev too high, exposing its poor refinement. It also makes the car feel slower when accelerating”.

So its not just me.

Nobody said it was just you, not sure why you are always so defensive in your arguments?.

Regarding your figures, i don't know where you are getting them from, but i know for a fact that the current jazz 1.3 CVT will go from 30-70mph in 10 seconds, because i timed it myself with the help of my son sitting in the passenger seat. So if the fabia does take 8.9 seconds through the gears to do the same, that isn't really all that impressive, given the fabia has 62% more torque at 60% fewer revs. In addition, the time recorded for the fabia to accelerate from 50-70 through the gears will have it starting off already in whichever gear most appropriate for maximum effect, whereas the time i recorded was starting off from point where the engine was pulling around 1700rpm, which meant i had to wait for the box to decide and sort out which of its 7 artificial ratio was most appropriate for maximum response. So maybe a half a second or so to sort itself out?.

If that was not enough, the honda is at least 47kg heavier than the fabia as standard, and i had my 15 year old son (about 60kg) in the passenger seat. Tot all that up and the jazz has a power to weight ratio of 82bhp per ton (including an 80kg driver and a 60kg passenger) versus 96bhp per ton (with an 80kg driver) for the fabia.

So lets sum that up, the fabia 1.0 tsi 110 has a 17% better power to weight ratio (in this particular instance), 8% more bhp, 62% more torque at 60% fewer revs, and last but not least, a 250% wider power band. With all that advantage, it manages to beat my (hopelessly slow and rubbish) jazz cvt from 50-70mph by only 11%, assuming of course that your quoted figure for the fabia is accurate. And, if i were to factor in half a second for the transmission to get itself in the correct ratio for maximum attack, the fabia's advantage would drop to 6%.

Which really is not enough of an advantage to justify constantly bleating on about how rubbish CVT's are and the supposed superiority of your beloved VAG tsi engines.

One last thing, you use 'what car' to corroberate that the jazz CVT is a bad car?, would that be the same 'what car' that thinks the ford 1.0 ecoboost engine is the best thing since sliced bread?, 'cos they obviously know what they are talking about.

Whatever the figures might be, there's no doubt in my mind that hybrids are best suited to drivers who do most of their mileage in and around towns and cities, and so have no need for any spirited acceleration..

Toyota - CVT with a launch gear - skidpan

So badbusdriver, you argue that a heavier, less powerful Honda Jazz fitted with an inefficient CVT is as fast or even faster than a lighter, more powerful Skoda Fabia with an efficient manual gearbox even though every magazine test I have read clearly disagrees. I have driven a Jazz many times in the past, it was an early one and a manual but that car was not as quick in the real world as our old 1.2 Micra which had less power and torque but was lighter.

I can see know why you are so deluded with your recent videos.

I'm not arguing at all, you do quite enough of that for everyone else. I'm simply stating the case and facts for the jazz CVT from someone who has now owned one for nearly a year now, as opposed to accepting the opinion of someone who hasn't.

You gave the figures for the fabia, i can't comment on that as i have neither driven or timed one from 30-70mph. But i have timed our jazz, so i know it can do it in 10 seconds (with a passenger). As it happens, i also know that it does 50-70mph in exactly the same time (6 seconds) as our previous car, a hyundai i30 turbo diesel auto (t/c) which had 280nm of torque @ 1500 rpm versus 123nm @ 5000 rpm of the jazz.

As for your extensive magazine reading on the jazz CVT, i find that very hard to believe. 1, because very few magazines road test small automatic cars of any kind. And 2, of those magazines, very very few of them bother to do the mid range acceleration timing anymore. I think Autocar does, but not sure of any others, and i am a serial car magazine buyer. So perhaps you could enlighten us with dates and titles for all these magazine tests of the jazz CVT you refer to?. I also surely can't be alone in wondering why you spend so much time reading magazine tests of cars you don't like?.

And i am not at all surprised at you describing me as 'deluded', after all my opinion differs from yours.

And another thing, just out of curiousity, which of my recent video's are you referring to?. I know my memory is not what it once was, but i don't recall ever posting a video on the forum, let alone recently.

Toyota - CVT with a launch gear - skidpan

I have in front of me a brochure for the new Jazz, I picked it up when we went to look at the HRV last month (walked away from that because of the woeful performance from a non-turbo engine).

The Honda figures are 0-60 12.1 seconds for the CVT version, Honda who make then say the manual is faster. Unfortunately they don't quote in gear figures.

Skoda's figures for the Fabia are 0-60 in 9.5.

But as we all know 0-60 times are irrelevant in the real world but its clear from the manufaturers figures which is the quicker car.

As for torque your Honda as you say has 123 Nm @ 5000 rpm (about 91 lbs in old money). The Fabia has 200 Nm @ 2000 -3500 rpm (about 148 lbs in old money). That is 62% more at much lower revs and a much wider powerr band.

There is no way on this planet that a lighter car with more power and a wider powerband is going to be slower es[ecially when the heavier car is saddled with a CVT which can only be described as the devils work.

For the record 50 - 70 in 6 seconds is about the same as a VAG 1.4 TSi in 4th gear and that is a car with 184 lbs of torque.

Sorry but I think you need a new watch.

1, At no point did i say or imply the jazz was quicker than the fabia.

2, At no point did i say or imply that the jazz is a better car than the fabia.

3, At no point have i slagged off either you or your choice of car *

(*This is because i am an adult)

This may well surprise you, but i really don't care whether or not you do or don't believe the figures i quote for the jazz. I know how fast it is (for the record, my son did the timing on his smartphone), i know how well it steers, handles and brakes. I don't know what the fabia can do, nor do i claim to.

I don't place much, if any, faith in what the motoring press say about any car which doesn't meet what they consider an acceptable level of performance. Unless the car in question can get round the 'ring in whatever time, hit 60 in under 6 seconds, and be able to hang it's tail out at will, imo, they really are not very objective.

And, surprise surprise, my request that you tell us about all these road tests which describe how slow the jazz CVT gets from 30-70 have gone unanswered. Could it be that they are fictional?.

I'm also waiting to hear about my recent video's, which apparently prove me to be deluded?

It was an Autocar test carried out when the CVT was reintroduced to replace the unloved box used in the first Mk2's. My god, that must have been bad. Even with the CVT box the test was not complimentary, the car came well down the list.

Just found a AutoExpress review for the latest Jazz. the manual does 30-70 through the gears in 10.4, there is no way a CVT will be as quick as that so I totally believe the Autocar test of the Mk2.

AutoExpress go on to say "We haven't been bowled over by the CVT auto gearbox - we’d avoid it unless you absolutely have to have an automatic, as it’s an unpleasant operator"

The Jazz is not a bad car, dad's was totally reliable for 5 years but he was pleased to see the back of it bacuse of the ride, noise and seats. The Note is a far better car in just about every respect but Nissans inept marketing people have simply ignored it and the public have followed their example. But as with the Jazz all the reports have said that the CVT version is truly dreadful.

There is no reason why any car should not get to 100,000 miles reliably if it is maintained correctly with regular oil changes. The ones we hear about on here with issues are generally cars with no history and missing services. A vast majority of owners never see a garage between services and don't use forums.

Toyota - CVT with a launch gear - bazza

Hmmmm I've not yet owned a car that's reached 100k with no issues. Engines are generally fine but things like suspension springs, wheel bearings, electrical gremlins have been irritating. Last car, an Octavia had a great engine but build quality was lacking in several areas, the one before that the same. Best car to date believe it or not a Renault megane!

Toyota - CVT with a launch gear - skidpan

Hmmmm I've not yet owned a car that's reached 100k with no issues.

Only had one car from new that I have done over 100,000 miles in and can vouch for the way it was maintained and driven from day one.

It was a Golf Mk2 GTi. From memory (and its a long time ago) it had the following in addition to normal servicing.

At the 10,000 mile service (all under warranty) the water pump was replaced (slight weep) and the clutch was replaced (difficult to get gear when stationary on occations).

Front brake pads replaced at 35,000 miles and 70,000 miles and the discs at 70,000 miles.

Rear brake pads replaced at 70,000 miles but only because on caliper had to be repaired since the handbrake cam was sticking. Not really necessary but while they were apart it was daft not to.

Cam belt at 75,000 miles.

Thermostat housing O ring about the same time.

Pretty cheap motoring.

After 100,000 miles we got a Golf TDI and we used the GTi less. Between 100,000 miles and when we sold at just over 7 years old (about 2 years) it had a battery and an exhaust.

Still cheap motoring.

Not included tyres and a windscreen but you expect those during that time period. I guess the brakes and cam belt were expected as well.

Should be added that for the first 5 years of its life it towed the Caterham on a covered transporter (weighing about 22 cwt in total) about 15 weekends a year. The car was loaded with toold and spares so it did not lead an easy life.

It will never happen again, don't do enough miles now or tow.

Toyota - CVT with a launch gear - bazza

Ah the mk 2 GTI, favourite car ever! I had the standard mk2 and never quite got round to the GTI, lovely car! Worth good money now in good condition.

Toyota - CVT with a launch gear - Avant

I've only taken three cars over 100,000 miles - and all were Renaults, an Espace, a Safrane and a Laguna V6: all petrol and (more to the point) all before Renault's standards alipped after 2000. None had any major issues - I can remember a new head gasket on the Espace at over 100,000 (forgivable) and that's about it.

Toyota - CVT with a launch gear - SLO76
100,000 miles... it’s just run in. I’ve run loads of six figure cars and flogged plenty more. There’s no reason why a well maintained motor won’t run well beyond 100k but too many people start basing their maintenance on the value of the car. They won’t spend £400 to get an old car that has little worth through another Mot and instead bin it then spend thousands to replace it which often ends up costing just as much to keep going. Often you really are better with the devil you know.

I’ve recently talked an old pal into spending a few quid to get the old Mitsubishi Colt 1.6 GLX auto I found for him through another Mot even though it will cost more than the car is worth it is a good reliable little car with plenty of life left if he replaces a rotten front crossmember and patches a blowing exhaust.

Big fan of the Mk II Golf GTi too. Still kicking myself for walking away from a near mint red 89 8v 3dr a couple of years back because the seller refused to budge by a single penny on price, I just can’t handle that, my dealer mind won’t accept the words no discount.

A Safrane! Always had a soft spot for large french exec saloons.

Should know better but me too, particularly the Safrane with Volvo’s 2.5 5cyl. Shame no one makes a big slushmobile hatch today. Skoda’s Superb comes close but it’s a bit Germanic.
Toyota - CVT with a launch gear - Avant

Oddly enough, the main reason why the Safrane didn't sell well, at least in the UK, was its stablemate the Laguna, which was introduced shorfly after the Safrane. The Laguna had plenty of room for three in the back and the boot was very nearly as big.

After someone had driven into my Safrane, we went on holiday in a courtesy Laguna while mine was being repaired. The Laguna swallowed five of us and all our luggage, including an extra suitcase which elder daughter had sneaked in and we only discovered part way through the holiday.

The Laguna V6 was a lovely car which instilled in me a fondness for six-cylinder engines that I haven't lost.
