How much hp does a Lexus IS 350 have?
The latest Lexus IS 350 delivers about 311 horsepower, while older models typically logged around 306 horsepower. The exact figure depends on model year and market.
Power by generation
The following outlines the official horsepower ratings for the IS 350 across its generations and major updates.
- First generation (model years 2006–2013): 306 horsepower from a 3.5-liter V6 (2GR-FSE).
- Second generation pre-facelift (roughly 2013–2016): still rated at 306 horsepower.
- Second generation refresh (roughly 2017–2020): horsepower increased to 311 horsepower thanks to an updated 3.5-liter V6 (2GR-FKS) and revised tuning.
- Current generation (model years 2021–present): 311 horsepower from the 3.5-liter V6 (2GR-FKS) with an 8-speed automatic gearbox.
Note: Some markets and trims may have slightly different ratings due to emissions tuning or measurement standards. In particular, the U.S. typically uses SAE net horsepower, while other regions may report small variances. The general range remains around 306–311 hp depending on year and market.
Engine and performance context
horsepower alone doesn’t tell the whole performance story. Weight, drivetrain configuration (rear-wheel drive vs. all-wheel drive), gearing, and traction all shape real-world acceleration and driving feel. The 311-horsepower variants typically pair with an 8-speed automatic transmission and are widely used across the IS 350 lineup, while earlier 306-horsepower versions relied on older transmissions and tuning.
Common questions about IS 350 horsepower
- Do all IS 350 models have the same horsepower? In a given generation, output is generally consistent, but market-specific tuning and emissions settings can create small variances. - How does horsepower affect performance? Higher horsepower usually improves acceleration and top speed, but weight, gear ratios, and drivetrain also play critical roles. - Are there performance-focused variants? The IS 350 F SPORT line uses the same engine output, with sport-tuned suspension and handling characteristics that affect overall performance perception rather than a higher horsepower figure.
Summary
In brief, the Lexus IS 350 currently produces about 311 horsepower in most markets, with older generations anchored around 306 horsepower. The notable horsepower bump arrived with a mid-cycle refresh that adopted the 2GR-FKS engine, and since then the IS 350 has been widely rated at 311 hp.
