The performance of Lexus’ hybrid vehicles should be evaluated based on this claim: maximum efficiency no matter the road conditions.
The Lexus hybrid’s smooth coupling of its gasoline and electric motors with its electronically-controlled continuously variable gearbox, or E-CVT, provides a means of fulfilling this promise.

What is E-CVT?
The intelligent transmission E-CVT has access to an endless number of gear ratios. It chooses the best (most efficient) gear ratio at that specific moment by continuously analyzing the vehicle’s speed, the road’s circumstances, the engine’s power, and the driver’s input.
When that time has passed, the clever arrangement of planetary gears visible in the rendering above allows it to seamlessly and imperceptibly shift to the next ratio. This setup is fundamentally different from the drive belt and conical pulley arrangement of more conventional continuously variable transmissions.
Why is E-CVT ideal for petrol-electric hybrids?
The engine may run at its fastest speed to either drive the automobile or charge the batteries without being constrained by fixed gear ratios. Additionally, the twin-input E-CVT can be utilized to direct propulsion from the electric motors to the wheels in place of the gasoline engine if the computer determines that it is not necessary to keep it running for a while.
The transmission improves driver engagement in two ways when available. First off, models with an E-CVT system sequential function give the impression of manually shifting gear ratios by ensuring a better fit between increases in engine and vehicle speed. Additionally, stepped engine braking force is delivered using this during acceleration.
Second, models having an E-CVT sport mode that increases engine speed more quickly during acceleration alter the perception of dynamic performance. This is seen in the diagram below.
We are confident that E-CVT fulfills its promise of efficiently transferring propulsion and performance to the driving wheels as a crucial component of the Lexus Hybrid Drive experience. Why not give it a shot?
How dependable is the Lexus CVT?
Although conventional and dual-clutch automatics are more common, CVTs are very smooth in urban environments and are favored by hybrid vehicle manufacturers like Toyota and Lexus.
Because of how they function, CVT gearboxes are typically quite trustworthy and provide exceptional fuel efficiency. They provide you immediate power when you want to start moving, but not everyone will enjoy the noise they generate when accelerating quickly. The best automobiles with CVT transmissions are currently for sale, if you can handle that.
What type of transmission does Lexus employ?
For its ES 350 car, Lexus has unveiled a brand-new 8-speed direct-shift automatic transmission. The ES now produces 300 horsepower and 355 pound-feet of torque thanks to a newly redesigned 3.5-liter V6 engine that is intended to provide powerful acceleration and a better sound.
The new eight-speed direct shift automatic transmission has been optimized to offer perfectly timed shifts with quick pedal reactions. It features an ultra-thin torque converter and a multi-plate lock-up clutch to more efficiently transfer power to the front wheels.
Which SUV is not equipped with a CVT?
BMW X5. You’re in luck if you’re looking for a fantastic premium SUV without a CVT transmission. Not only does the X5 not have a CVT, none of BMW’s SUV models employ one either. The X5 is really opulent and has a wonderful driving experience.
Exist any reliable CVT transmissions?
Considering purchasing a CVT-equipped vehicle as your next vehicle? It depends on whether you want to operate a gear-driven vehicle or not.
Although continuously variable transmissions (CVT) are not a recent technology, it has only been in recent years that drivers have gotten increasingly accustomed to them.
The DAF 600 was first made by the modest Dutch company van Doorne Automobiel Fabriek (DAF) in 1958. Even though it was one of the first mass-produced vehicles using a CVT, the vehicle was a failure. Subaru released the Justy, a CVT-equipped vehicle, in 1987. However, it was also a market failure for a number of reasons, such as worries about CVT dependability and the noise they omit.
Despite their often unfavorable reputation, CVTs do have some benefits, including as significantly increasing an engine’s fuel efficiency when it accelerates and being said to be less expensive than current eight- and nine-speed automatic gearboxes.
What Is a CVT?
The majority of automatic transmissions run on gears. Conversely, CVTs don’t even have any gears. The alternate name for them is pulley transmission since they run on a system of movable pulleys connected by a belt.
Drivers began to accept CVTs after Japanese carmaker Nissan introduced its Murano SUV with one in 2003. These days, CVTs are an ubiquitous sight on our roadways. Nissan, for example, provides the CVT on a variety of its models, including the Murano, Altima, Maxima, Rogue, Sentra, and Versa. Additionally, some Jeep Compass and Patriot models, BMW Minis, Mercedes-Benz Class Bs, some Honda Civic Hybrids, Mitsubishi Lancers, and a few Toyota vehicles all come with CVTs. Both Chrysler and Ford offered CVT-equipped automobiles, but they changed course after a while because customers believed the reliability of CVTs was in question.
CVT Maintenance and Repair Advantages and Disadvantages
The reliability of CVTs is comparable to that of conventional automatic transmissions in most cases. However, it’s possible that their use is more appropriate for smaller cars than for larger ones.
However, proactive preventative maintenance on some CVT models may necessitate regular transmission fluid changes, especially when compared to conventional sealed automatic transmissions, which can function for up to 100,000 kilometers or more before requiring maintenance. The CVT’s biggest enemy is heat. As a result, certain oils are needed for certain transmissions.
Toyota CVT
The Toyota CVT transmission is marketed as the greatest option for both performance and fuel economy. The most effective elements of the traditional transmission and CVT are combined in Toyota’s Direct Shift CVT.
The Direct Shift-CVT uses a standard transmission’s initial gear to assist the car accelerate more quickly. The transmission switches to a CVT mode once the vehicle reaches the speed where a CVT is preferable. The following are the Direct Shift-top CVT’s advantages:
- an increase in fuel economy of 6%
- increased belt effectiveness
- Ratio spread has increased by 15%
- amazing shift speed
- a small belt angle
The following Toyota models have a regular CVT (not a Direct Shift CVT):
- Corolla, Toyota
- Honda Accord
- Honda CR-V
- Subaru Prius
- Honda C-HR
Toyota is frequently praised for its dependability. They have experienced recalls even though this is generally the case. The 2019 Toyota Corolla Hatchback was subject to one of the largest recalls because the CVT’s torque converters were prone to breaking.
Honda CVT
The Honda CVT has a special feature called Honda Control. The auto identifies “sporty driving” (i.e., driving down a curving road) and will keep the engine running at a higher speed. The vehicle enhances the smoothness of the ride during acceleration and deceleration by keeping a greater engine speed.
The Honda CVT offers the following key advantages:
- increased fuel efficiency
- smoother gear shifts for a more comfortable ride
- Honda Management
Numerous Honda models come with CVTs, such as:
- Subaru Insight
- Honda Accord
- Honda Civic
- Subaru Fit
Honda recalled a significant number of CVT transmissions. The 2014 and 2015 Honda Civic was subject to one recall because of a software problem with the transmission. Drive shaft pulleys broke as a result of pressure the program put on the CVT pulley. In addition, Honda is being sued for CVT transmission issues with the 20162018 Honda Civic, where the car claims to be in park when it is not.
Mercedes uses CVT transmissions, right?
Now that you know what a CVT is, you’ve probably observed that many Mercedes-Benz cars have dual-clutch transmissions, but there aren’t any CVTs to be found!
Who is the owner of the worst CVT?
However, Nissan CVTs are also notorious for breaking down quickly, which is why several lawsuits have been filed against them. The transmissions have a bad reputation for trembling, making odd noises, overheating, and putting the car into “limp mode.” The CVTs made by Nissan, according to some, are the worst transmissions ever created.
Which automobile has the best CVT?
The Top 14 Budget CVT Vehicles in India for 2022
- Micra by Nissan.
- Baleno CVT from Maruti Suzuki.
- The CVT Hyundai Elite i20.
- Nissan Jazz.
- Amaze Honda CVT.
- CVT Nissan Sunny.
- Nissan Yaris.

What CVT is the most trustworthy?
Having said that, not all CVTs are made equal; some are superior to others. These vehicles all feature CVTs.
Honda (Jazz, City, CR-V, Civic, HR-V, Odyssey), Subaru (Forester, WRX), and Toyota make some of the greatest CVT-type automatics we’ve tested so far (C-HR, Corolla Altis, Vios, Yaris).
Due in significant part to the use of a torque converter to transfer power to the driving wheels, the CVT-type automatic transmission that is installed in these cars offers quiet operation and smooth acceleration.
However, the CVT installed in the Subaru WRX is the one that has so far shocked us the most. You wouldn’t be aware that the car has a CVT transmission if we hadn’t told you.
Contrary to other CVTs we’ve experienced, the Subaru WRX launches itself with great vigor when asked for more, and the CVT matches the shifting characteristics of conventional automatics, increasing the whole experience.
Then there is Proton, which continues to insist on equipping its vehicles with CVTs that have a start-up clutch.
Punch-sourced CVT-style automatic transmissions are installed in Proton vehicles such the Exora, Iriz, and Persona.
While it may appear positive on paper, Proton vehicles with CVTs are jerky in traffic, loud, and unrefinedexactly the reverse of what a CVT should be.
At least Hyundai-sourced 4-speed torque converter automatic has been installed in place of the Saga’s CVT by Proton.
To be honest, Mitsubishi’s application of CVT in models like the Outlander and ASX may best be regarded as average, as it is frequently hesitant when the pedal is pressed all the way to the floor and is far from being as responsive as its competitors. At motorway speeds, the noise level is likewise fairly loud.
Is there a CVT in the Lexus ES 350?
Three different powerplant options are available for the Lexus ES. A 2.5-liter four-cylinder engine with 203 horsepower powers the ES250, which also has all-wheel drive as standard. The 3.5-liter V-6 engine found in all ES350 models produces 302 horsepower and is mated to an eight-speed automated transmission that drives the front wheels. A hybrid powertrain with a net output of 215 horsepower powers all ES350h models; a continuously variable automatic transmission (CVT) and front-wheel drive are included as standard equipment. The gas-only ES350 accelerated from a complete stop to 60 mph on our test track in 6.1 seconds. The hybrid ES350h and all-wheel drive ES250 completed the dash in slower times of 8.1 and 8.3 seconds, respectively. This Lexus sedan has the calm handling and accommodating riding qualities that many buyers of premium vehicles adore. The F Sport variant adds bigger wheels and performance-oriented suspension adjustments for consumers looking for sharper handling. But even with this improvement, the ES is less sporty than rival vehicles like the BMW 5-series.
Are there gearbox issues with Lexus?
Drivers of Toyota and Lexus vehicles have reported problems with a potential gearbox flaw that results in stuttering, bucking, jerking, or even an abrupt loss of power. Other transmission issues reported include:
- shifting issues, such as jerky, delayed, abrupt, or no shifting at all
- a transmission problem
- varying from early transmission wear to failure
- accelerating issues
- acceleration and deceleration that are significantly delayed or abrupt
