Does the Lexus IS250 have a CVT transmission?

The concise answer: no. The gasoline-powered IS250 does not use a continuously variable transmission (CVT); it is paired with a traditional six-speed automatic gearbox in most markets.

To understand what this means, it's helpful to look at how the IS250's drivetrain was configured across generations and markets, and how the hybrid variant differs from the standard gasoline model.

Gasoline IS250: transmission basics

The IS250, produced as part of the first-generation IS lineup, pairs the 2.5-liter V6 engine with a conventional electronically controlled six-speed automatic transmission. This 6AT setup provides standard automatic shifting and, in many markets, a manual shift mode, but it is not a CVT. Across most regions, the gasoline IS250 did not offer a belt-and-pulley CVT at the factory.

Hybrid IS variants and the CVT-like system

For customers seeking a hybrid, Lexus offered the IS 250h (also known in some markets as the IS 300h). These hybrids use Toyota/Lexus Hybrid Synergy Drive, which integrates the gasoline engine with electric motors and employs an e-CVT (a CVT-like setup used in hybrid systems) rather than a conventional automatic for the gasoline engine alone. This configuration is part of the hybrid system and is not the same as a traditional CVT used in non-hybrid IS250 models.

What about newer IS models?

Over the years, Lexus updated the IS lineup, but the standard gasoline IS models have generally continued to rely on conventional automatics, while hybrids use the e-CVT-based hybrid drive. There is no factory CVT option for the gasoline IS250 variant.

Summary

In short, the Lexus IS250 gasoline model does not use a CVT; it employs a traditional six-speed automatic transmission. If you’re evaluating the IS250’s hybrids, note that those systems use a hybrid-specific, CVT-like arrangement as part of the Hybrid Synergy Drive rather than a belt-driven CVT for the gasoline engine alone.

Does Lexus have CVT transmission?

Yes, Lexus uses Continuously Variable Transmissions (CVT) in some of its vehicles, particularly in its hybrid models. Lexus calls its specific version an "e-CVT," which is an electronically controlled continuously variable transmission that combines a CVT with a planetary gearset to simulate traditional gear changes. 
Lexus hybrid transmissions

• LC 500h: This model uses a unique transmission that blends a CVT with a four-speed automatic to create nine "virtual" gear ratios. 
• RX Hybrid: Some RX hybrid models, like the RX 350 Hybrid, come standard with an e-CVT that is paired with the hybrid powertrain. 
• UX200: The 2019 UX200 was the first production vehicle to be equipped with a CVT that is paired with a "gear" setup. 

Other Lexus vehicles

• Non-hybrid models: Lexus generally does not use CVTs in its non-hybrid models, preferring other types of transmissions. 

What year to avoid Lexus is 250?

You should avoid Lexus IS 250 models from the 2006-2009 years, as they are prone to issues like carbon buildup in the engine, melting/sticky interior plastics, and an outdated infotainment system. Models from 2010 and newer are better because they have updated piston rings to address the carbon buildup issue and revised interior components. The Lexus IS 350 is often recommended as a better alternative due to its more powerful engine and avoidance of the specific 250's direct injection engine problems. 
Years to avoid

• 2006-2009: These years are known for significant problems.
  • Engine: The direct injection engine is prone to carbon buildup, which can lead to oil consumption and misfires. This issue was a major reason some owners avoid these years altogether.
  • Interior: Many owners reported melting or sticky dashboards and door panels, especially in these model years.
  • Infotainment: The navigation and overall infotainment system is considered very outdated by modern standards. 

Recommended models

• 2010 and newer: These models are the preferred choice for the IS 250 because they feature an updated engine with revised piston rings to combat the carbon buildup problem.
• 2010 and newer: These years also have updated interior components, which should prevent the melting/sticky dash and door panel issues.
• IS 350: If your budget allows, the IS 350 is often recommended as a more powerful alternative that does not have the specific direct injection engine problems found in the IS 250. 

Other considerations

• Even with the updated 2010+ models, regular maintenance is crucial. Owners recommend consistent oil changes and checking the fluids to ensure the longevity of the vehicle. 
• Some owners of the IS 250 have successfully maintained their older models by following a rigorous maintenance schedule and addressing issues as they arise. 

Which lasts longer, CVT or automatic?

Both systems require care, but they wear in different ways. CVTs may need more frequent fluid changes and can be more costly to repair when they fail. Automatic transmissions tend to last longer and are often easier to service—though that depends on the make and model.

Which Lexus is not CVT?

Many non-hybrid Lexus models are available without a CVT, including most gas-powered Lexus sedans and SUVs that use a traditional automatic transmission. You can find models with traditional automatics like the Lexus IS 250, and many newer non-hybrid Lexus models such as the ES 250, which uses an eight-speed automatic, and many others. Lexus also has hybrid models, which use an eCVT (electronic Continuously Variable Transmission), but these are mechanically different from belt-driven CVTs used in other brands.

Lexus models without a CVT

• Gas-powered sedans: The Lexus IS 250 historically came with a six-speed manual transmission, and other gas-powered models like the ES 250 feature a traditional eight-speed automatic. 
• Gas-powered SUVs: Many gas-powered SUV models, such as the Lexus RX 350, use traditional automatic transmissions instead of CVTs. 
• Note on hybrids: While many Lexus hybrids use a continuously variable transmission, they are often referred to as "eCVT" (electronic Continuously Variable Transmission) and are mechanically different from traditional belt-driven CVTs.

How to identify a Lexus without a CVT

• Check the model: Look for models that are not hybrid or electric, as these are more likely to have traditional transmissions. 
• Read the specs: Always check the specific model's specifications to confirm the transmission type, especially for hybrid models. 
• Consider manual transmission: Some recent Lexus models have reintroduced manual transmissions, so if that is your preference, look for specific manual models like the new LBX hot hatch.
