Is the IS250 a V4 or V6?
The Lexus IS250 is equipped with a V6 engine, not a V4. The IS250 features a 2.5-liter V6 engine that produces 204 horsepower and 185 lb-ft of torque.
Detailed Explanation
The Lexus IS250 is a compact luxury sedan that was produced by Toyota's premium brand Lexus from 2005 to 2013. This model was positioned as the entry-level offering in the Lexus IS lineup, slotting below the more powerful IS350 and high-performance IS-F variants.
Under the hood, the Lexus IS250 is powered by a 2.5-liter V6 engine. This naturally-aspirated 6-cylinder powerplant features dual overhead camshafts (DOHC) and 24 valves. It produces 204 horsepower at 6,400 rpm and 185 lb-ft of torque at 4,800 rpm.
The IS250's V6 engine is part of Toyota's 4GR-FSE engine family, which was also used in other Lexus and Toyota models. It utilizes direct fuel injection and variable valve timing to optimize power and efficiency.
It's important to note that the Lexus IS250 does not have a V4 engine option. V4 engines, which have four cylinders arranged in a V configuration, are relatively uncommon in modern passenger vehicles. The IS250 was exclusively offered with the 2.5-liter V6 as the standard powertrain.
Conclusion
In summary, the Lexus IS250 is equipped with a 2.5-liter V6 engine, not a V4. This smooth and efficient 6-cylinder powerplant was the sole engine choice for the entry-level IS250 model during its production run from 2005 to 2013.
