Is Lexus is 250 4 cylinder or 6 cylinder?
The IS 250 uses a six-cylinder engine, specifically a 2.5-liter V6, not a four-cylinder.
Across its generations, the IS 250 has served as Lexus' mid-size sedan option powered by a 2.5-liter V6 in many markets. As generations evolved, Lexus introduced other drivetrains and eventually phased the IS 250 badge out in favor of turbocharged four-cylinders and hybrid configurations. This article breaks down the engine configuration for the IS 250 and how it fits into the broader IS lineup.
Engine configuration and specs
Before delving into specifics, here are the key details about the IS 250's engine layout.
- Engine displacement: 2.5 liters
- Cylinder arrangement: V6 (six cylinders)
- Power output: around 204 horsepower, with minor variations by year and market
- Transmission: commonly paired with a 6-speed automatic transmission in most markets
- Production span for IS 250 (typical markets): roughly 2006–2013, with the IS 250 Convertible (IS 250C) following from 2009–2015
In practice, this setup gave the IS 250 a smooth, refined character aimed at balanced performance and reliability, rather than the maximum horsepower of some rivals.
Is there a four-cylinder option in newer IS models?
In the third generation and later, Lexus shifted its IS lineup toward turbocharged four-cylinder options in many markets, while preserving higher-displacement V6 variants for those who want more power. The IS 250 badge itself has become less common in newer models.
- IS 300 (where offered) typically uses a 2.0-liter turbocharged inline-4, delivering strong performance with improved efficiency
- IS 350 continues with a 3.5-liter V6 for higher power output
- Some markets offer hybrid versions that pair efficient four-cylinder petrol engines with electric motors
Overall, the IS 250 name is largely historical in the modern lineup, but it remains a point of reference for enthusiasts looking at late-2000s Lexus sedans.
Summary
Bottom line: The Lexus IS 250 is a six-cylinder vehicle, powered by a 2.5-liter V6 in its traditional form. As Lexus evolved the IS lineup, four-cylinder turbo engines and hybrid options became more common, and the IS 250 badge is now less common in the current market.
