Is a Lexus IS250 a 4-cylinder?
The short answer: No. The Lexus IS250 is powered by a 2.5-liter V6 engine, not a four-cylinder.
In more detail, the IS250 badge has traditionally signified a model in Lexus’ IS line that uses a 2.5-liter V6. While the broader IS lineup has included four-cylinder engines in certain markets and model years (especially as Lexus expanded into turbocharged and hybrid variants), the IS250 itself is not a four-cylinder. Understanding this helps explain why the IS250 feels different in acceleration and refinement compared with four-cylinder IS models that appeared in various markets later on.
Engine configurations in the IS lineup
To place the IS250 in context, here are the engine configurations commonly found in the IS range across generation years and markets.
- IS250 (approximately 2005–2013 in the US and many other markets): 2.5-liter V6 engine, about 204–208 horsepower, delivering smooth, refined performance.
- IS350: 3.5-liter V6 engine, around 306 horsepower, offering stronger mid-range power.
- In some markets and later years, IS models offered turbocharged or hybrid four-cylinder options (e.g., 2.0-liter turbo inline-four variants such as the IS 200t/IS 300 and related hybrids), which are separate from the IS250 badge.
Bottom line: The IS250 badge does not indicate a four-cylinder engine; if you’re seeking a four-cylinder Lexus sedan, you would be looking at other IS variants in certain markets (such as the 2.0-liter turbo four in later IS models) rather than the IS250.
How to verify the exact engine in your car
To confirm the engine configuration on a specific vehicle, use these steps:
- Check the engine code stamped on the engine block or on an engine bay label—the code will indicate V6 versus inline-four.
- Consult the vehicle’s window sticker or owner’s manual for the listed engine specification.
- Enter the VIN into Lexus’ official service portal or a reputable automotive database to pull the original engine specification for that exact car.
- Physically inspect the engine bay: a V6 will have six cylinders arranged in two banks; a four-cylinder will have four cylinders clearly visible.
Note: Naming conventions and available engines can vary by market and model year. Always verify with official documentation for your exact vehicle.
Summary
In summary, the Lexus IS250 is not a four-cylinder. It uses a 2.5-liter V6 engine, which distinguishes it from the four-cylinder IS variants that exist in certain markets and generations. If you’re comparing models, look for engine specifications rather than just the badge to understand the powertrain accurately.
