What gearbox does Lexus use?

In brief, Lexus uses a mix of transmissions depending on the model: an eight-speed automatic for most gas-powered cars, an electronic CVT (e-CVT) for hybrids, a 10-speed automatic on certain performance/flagship models, and a single-speed gearbox for its electric vehicles.

As part of its broader electrification strategy, Lexus tailors its gearbox choices to balance efficiency, acceleration, and driving feel. This article breaks down how those choices map to different drivetrain families across the lineup.

The main transmission families in the Lexus lineup

Below is a concise guide to the four primary gearbox architectures you’ll encounter across current Lexus models, noting where each is typically found.

Direct Shift eight-speed automatic (8AT) for most gasoline-powered models

e-CVT (hybrid transaxle) for Lexus hybrid and plug-in hybrid models

Ten-speed automatic (10AT) for certain performance and flagship models

Single-speed gearbox for electric vehicles (BEVs)

These four families cover the broad spectrum of Lexus powertrains, from everyday efficiency to high-speed performance and full electrification.

Gasoline-powered models: the Direct Shift 8AT

Most of Lexus’s non-hybrid gasoline cars rely on an eight-speed automatic known as the Direct Shift 8AT. This transmission is designed to deliver smooth, quick shifts and efficient cruising, and it has become the standard pairing for a wide portion of the brand’s current lineup.

Typical examples include popular sedans and crossovers such as the IS, ES, NX, and RX families

Used across many model years with updates that improve shift clarity and response

In practice, the 8AT aims to provide a balance of refined highway performance and responsive acceleration when you press the throttle, while also prioritizing fuel efficiency.

Hybrid and plug-in hybrid models: the e-CVT transaxle

When Lexus blends gasoline power with electric motors, it commonly uses an electronically controlled continuously variable transmission (e-CVT) inside the hybrid transaxle. This setup enables seamless power delivery from the gas engine and electric motor(s), optimizing efficiency and smoothness rather than abrupt gear changes.

Found in hybrids such as the ES Hybrid, RX Hybrid, NX Hybrid, and others in the lineup

Some plug-in hybrid variants also use a variation of the hybrid transaxle with similar CVT characteristics

The e-CVT approach sacrifices some traditional “shift feel” for efficiency and immediate torque from electric propulsion, a trade Lexus makes to maximize fuel economy and low-end responsiveness.

Performance and flagship models: the 10-speed automatic

For certain high-performance or flagship models, Lexus employs a ten-speed automatic to optimize acceleration, refinement, and high-speed cruising. The 10AT is associated with models that push stronger powertrains and sportier character, offering more gears to balance torque delivery with wide gearing.

Notable usage includes the LC 500’s V8-equipped configuration, aimed at delivering rapid acceleration and a composed highway experience

Other performance-oriented or flagship sedans may use the 10AT in different engine configurations

The 10-speed setup provides more closely spaced ratios at the lower end for quicker response, while maintaining tall gearing for efficiency at highway speeds.

Electric vehicles: single-speed gearboxes

With Lexus’s battery-electric models, such as the RZ, the drivetrain typically uses a single-speed reduction gearbox. This simple setup is well-suited to electric motors, providing strong low-end torque and straightforward maintenance while delivering smooth, predictable acceleration.

The RZ 450e uses a single-speed transmission connected to its electric motors

Future BEVs from Lexus are expected to continue with single-speed configurations

Electric platforms at Lexus favor simplicity and immediate electric torque, eschewing multi-gear transmissions in favor of efficiency and responsiveness.

Model-by-model snapshot and evolving lineup

Gearbox choices can shift with new model introductions and mid-cycle updates. Lexus has been expanding electrification and refining its transmissions to balance performance, efficiency, and driving feel across its portfolio.

Summary

In summary, Lexus does not rely on a single gearbox for the entire lineup. Instead, it uses a quartet of transmission architectures to match the powertrain in each model: an 8AT for most gasoline cars, an e-CVT for hybrids, a 10AT for select performance/flagship variants, and a single-speed gearbox for BEVs. This multi-gearbox strategy reflects Lexus’s approach to offering efficient everyday driving while preserving performance and preparing for a growing electrified lineup.

Are Lexus CVT gearboxes any good?

The E-CVT is highly reliable (it's probably the most reliable transmission available), but it is boring. It has no ``attachment'' to the engine since the engine RPM can vary as much as needed for highest efficiency, so for sporty driving it just doesn't feel very good.

What kind of transmission does Lexus use?

The vast majority of Lexus models that have ever been produced feature a self-shifting gearbox of one kind or another. Before the introduction of Lexus Hybrid Drive and its associated E-CVT technology, that meant the application of traditional torque converter type automatic transmissions.

Which Lexus does not use CVT?

Lexus: Every non-hybrid is not equipped with a CVT. Lincoln: The non-hybrid Corsair and non-hybrid MKX are not equipped with CVTs. Maserati: No modern Maserati is equipped with a CVT. Mazda: No modern Mazda is equipped with a CVT.

Which is better, CVT or 8-speed transmission?

A continuously variable transmission (CVT) offers a seamless and smooth ride with potentially better fuel efficiency, while an 8-speed automatic provides a more traditional driving feel with defined gear shifts and often better performance for towing and sportier driving. CVTs use a belt and pulley system for infinite gear ratios, while 8-speed automatics have fixed gears that the car shifts between.

Feature	CVT (Continuously Variable Transmission)	8-Speed Automatic
How it works	Uses a belt and pulleys to change gear ratios continuously, without fixed gears.	Uses a system of fixed gears that the transmission shifts between.
Driving feel	Smooth, uninterrupted acceleration with no distinct gear shifts. Can sometimes feel disconnected, with a "rubber band" effect.	Familiar, traditional feel with distinct gear changes. Can feel more responsive.
Fuel efficiency	Generally offers better fuel economy because it can keep the engine in its most efficient RPM range.	Generally good, but can be less efficient than a CVT because of the gear shifts.
Performance	Excellent for smooth, consistent acceleration, but can have limitations on the size and power of the engine it can be paired with.	Better suited for performance driving and heavy-duty tasks like towing.
Maintenance	Can require more frequent fluid changes and may have higher repair costs if they fail.	Generally considered more durable and easier/less expensive to repair.
