How much HP does a Lexus IS 300 have?

The Lexus IS 300’s horsepower varies by generation and market. In recent years it delivers about 241 horsepower, while older models used a 3.0-liter inline-six that produced around 215 horsepower.


Overview of IS 300 horsepower across generations


The following breakdown shows the most common engine configurations that have worn the IS 300 badge in major markets. Exact figures can vary by model year, trim, and drivetrain.



  • First-generation IS 300 (early 2000s): 215 hp from a 3.0-liter inline-six (2JZ-GE).

  • Modern IS 300 in the United States (2016–present): 241 hp from a 2.0-liter turbocharged four-cylinder, with torque around 258 lb-ft; typically paired with an 8-speed automatic and available with rear- or all-wheel drive.

  • Current IS 300 variants in some markets (global context): the 2.0-liter turbo setup remains the common IS 300 configuration, while certain markets use a hybrid variant (IS 300h) with a different combined-output rating.


In summary, the IS 300 moved from the 215-horsepower figure of early generations to about 241 horsepower in its modern turbocharged form. If you’re shopping, verify the exact model year and market to confirm the precise horsepower figure for that vehicle.


In-depth look by market and generation


Early generation IS 300 (2001–2005)


Power output for this era centered on the 3.0-liter inline-six, delivering approximately 215 horsepower and roughly 218 lb-ft of torque. This configuration was common in several international markets before the model bump to turbocharged powerplants in later years.


Modern IS 300 (2016–present in the US; global context)


Today’s IS 300 commonly uses a 2.0-liter turbocharged inline-four engine, producing 241 horsepower and about 258 lb-ft of torque. It is typically mated to an 8-speed automatic transmission, with rear-wheel drive standard and all-wheel drive as an option in many markets.


Hybrid and regional variants


Some regions offer a hybrid variant badge such as the IS 300h, which blends internal combustion and electric power for a different total output. These are not always labeled as IS 300 in every market, so the exact horsepower figure can differ depending on the region and model year.


Summary


Across generations, the Lexus IS 300’s horsepower has evolved from about 215 hp in its early 2000s form to 241 hp in the modern turbocharged lineup. Market-specific variants, including hybrids, can alter the official horsepower rating, so the precise figure depends on the model year and region.
