Great video! I hadn't thought about how the physical 1st gear takes the bulk of the load, reducing wear and tear on the belt. Another good thing - the physical 1st gear also increases the overall total gear ratio range or spread, i.e. a traditional CVT may only have a 2.5 to 1 ratio spread, but with the physical 1st gear, now the transmission has a higher spread. If that makes sense. Because one of CVT's problems *is* that lack of gear ratio range, forcing the designers to either choose a low numerical gear ratio for the differential for good mileage, or a higher numerical ratio for off-the-line performance but at the expense of economy.
Just physics,the most stress is when taking off to get that heavy SUV moving. Once moving the inertia is more and thus the load on the trans is less. Brilliantly done Toyota
yeah it will help, but still one of most important things still will be to cahgne oil. 80% CVTs failures were dure to pump failure which was cause by filings and dirty fluid. Most of filings comes from the outer of the drum which ahs metal to metal contact with the belt, and yes - its the contact from the lunch. So Toyota is right about it. But still - checking the oil in your CVT is and will be crucial.
If you can, get the hybrid. Electric car goodness without the electric car drawbacks. You get an electric car with gasoline engine assist. The assist engine is an efficiency tuned Atkinson cycle engine so anytime the engine is assisting the vehicle is using less fuel than a regular car. And using no fuel when the electric stuff doesn't need assistance. The assist engine provides assistance up through the planetary gearset which provides CVT action. Planetary gearsets avoid friction. Belt or chain CVTs count on friction.
Lexus have been putting CVT's into their petrol hybrid models (mostly outside the US) for some 10 years now and they're very good, really smooth and dependable.
Do people not realize lexus is high end toyota if anyone would make a reliable cvt its lexus because LEXUS IS LUXURY TOYOTA they are the same company with different brandings
New Holland put a cvt on the 8NA boomer back in 2010ish. All I hear is it is to be avoided. Most tractors have gears or hydrostatic, and gears last longer. That said the ecvt is better and I hope they get better. Meanwhile I'm avoidibg them.
The Fendt Vario is a closer relative design wise to the Toyota ecvt, with the planetary gear set. I hear they are very reliable if looked after. Of course other companies do their imitations to varying degree of success. ZF makes a similar CVT that seems to be successful in most applications.
I like your lexus. Very nice setup. Been considering trading in my 2008 RX400H for either a new RX500H F Sport, or a certified pre-owned GX series. But Lexus really disappointed me with that turbo 4 banger. While although the electric motors make up for the turbo lag, or so they say, the 0-60 just doesn't match the price tag, and honestly it's not all that much faster than my old granny 400H. Recently sold my Tacoma, because my little peice of heaven became way too crowded with all the tuner car kids trading in their Civics to build a "overland" Tacoma as they call it. Obviously i'm all about the SAS culture, overlanding isn't my thing, and I got tired of towing factory Tacos out of the trail for free. Leaning towards just doing a light lift and some light gear on a GX.
To be clear the E CVT is used in the lexus UX hybrids. DCVT in UX200 non hybrid and LBX. I'd go for the ECVT for durability as it is simpler in design.
Still rocking with my prius 2011 the mil almost 28+++++ and still working. On time service and dont focus on modify for performence the engine will be fine. Performence for daily use not bad and the fuel consumption is realy good😅
My mom just bought a low mile 2021 UX200 with the Direct Shift CVT that's mentioned here. Wow! Leave it to Toyota to fix the age old flaws of the CVT. Compared to other CVT crap boxes I've driven, the UX is way more responsive off-the-line and much crisper/quicker in it's "shifts." They've actually made a CVT that feels kinda fun to drive, but the long term reliability boost of the CVT components NOT having to pull 1st gear duty...just absolutely brilliant. I do hope other manufacturers will follow suit because this thing is more efficient than a traditional torque converter automatic or a conventional CVT and it's honestly more fun to drive than either.
Not having that launching first gear is what makes Subaru CVT suck for off-roading. It just cut torque at the most important moment and it is painful to watch and to listen.
The CVT used by Toyota or Lexus doesn't have a belt that can stretch, it uses a metal belt made of over 400 stamped metal plates that are pushed around the pullies, not pulled. The plates are held together by bands of flexible steel that constantly bend. If a steel band ever breaks, then the plates will all fall apart. The steel bands may suffer from old age, not from high torque. However, high torque may cause the surfaces of the coned shaped pullies to wear more rapidly leading to belt slippage. The wear and tear of the surface of the pullies may ultimately be reduced by having the launch gear. My C-HR did not come with a launch gear, so I "baby" my transmission by accelerating gently from a stop. My CVT will last longer and I get better fuel economy that way.
That one's a lot more similar to eCVT from Toyota/Lexus hybrids, except it uses hydraulics instead of electric motors. Same with the Vario transmission on Fendt tractors. No belts or variable size pulleys in any of them, just gears and a pump connected to a hydraulic motor.
@@LexusGX460-OFF-ROAD Yeh I was reading that the lexus had switched to CVT with rubber belts. If that was the case they would die fairly quickly I would have thought
My old Subaru Legacy had abyssmal torque and power with the CVT... the acceleration was absent and you do not feel the HP. Please Lexus stay away from this trash technology.
Your not lying Subaru CVTs are trash my 2019 only lasted till 120k, ended up getting it fixed through warranty and got a Lexus GS350. I heard someone with a 2024 model lasting about 200 miles 😂
Making a channel on just one model of a car (GX460) is........ not gonna get you a lot of subs but even then there's no guarantee of success unless there's excellence.
@@Frendo1 . I'm currently enjoying a 2013 Prius (and 2013 Mustang fastback) and hope to replace it someday with a vehicle using the Camry hybrid drive train. Probably a RAV4 or Crown. Maybe a used Vensa or Lexus SUV. Aging body needs a higher car 🤔

Wouldn't it be funny if the CVT finally completed it's evolution and overcame all it's problems and the final result was a geared transmission?
If someone was going to make a reliable CVT, it would be Toyota

I wonder can the combine the cvt with a turbo?

In europe we have Toyota auris 8nr fts 1.2turbo cvt, a pleasure to drive with toyota reliability.

Is the toyota Corolla LE 2022 cvt transmission reliable like the lexus cvt ?
When I heard they made CVT’s for farm tractors, I figured Toyota could actually make one reliable.
You make a very logical point 😃 ❤️
Yes. Excited to see what they'll do next!
Yup..things gettin better..wander when it will be applied on heavy duty truck trailers..

The new synergy drive on the hybrid doesnt have a belt or a chain
this is not the synergy drive (ecvt) this is the D-cvt.. 2 different systems
Hell toyota has used cvts for decades. They easily go to half a million miles in Prius taxis and Ubers.
those are e-CVTs in the Prius they do NOT have steel belts... this dCVT is a steel belt type of CVT
@@LexusGX460-OFF-ROAD and imagine how much more reliable they will be
Amazing we need more of these in the American market.
Our prius gen3 has over 365,000 miles and e-cvt still smooth as silk

eCVT isn’t even what you’d call a traditional CVT as it’s all mechanical (no belt). It’s only similar in function.
Is this the same transmission on the Corolla Cross?
Yes the cross is fitted the the launch gear as well..I own one..
Cvt was used in F1.. They banned for being too fast and strong. Look it up
Still have to maintain it... Change that fluid at 20-25k miles.

Since only the first gear (launch gear) has a direct drive, why do you keep talking about the 3rd. and 4th. gears?
It's a rubber belt not metal I think
traditional CVT is a segmented steel push-belt

JATCO cvts do NOT have a physical first gear. That system is patented by Toyota/Aisin... the Toyota DCVT is patented
Plus, wasn't JATCO purchased by Nissan/Renault? Their CVTs are trash. Found that out when my Murano's CVT failed at 83000 miles...
Nothing about lost of mind it all about technology. We need to understand cvt required to be service more regular than conventional transmission
