The 2007 Lexus GS 450h delivers a combined output of about 343 horsepower, blending a 3.5-liter V6 engine with electric motors. The gasoline engine is rated around 303 horsepower, with electric propulsion contributing the remainder to reach the total figure.


In detail, this model uses Lexus Hybrid Drive to pair a 3.5-liter V6 with electric motors, yielding a performance profile that emphasizes immediate torque from the electric components and sustained power from the gasoline engine. The result is a combined output that positions the GS 450h as a relatively quick luxury hybrid for its era, with power available across a broad RPM range.


Powertrain at a glance


Below are the key figures that define the GS 450h’s horsepower, broken out to show how the total is assembled.



  • Gasoline engine: 3.5L V6 (2GR-FSE) – about 303 horsepower

  • Electric motors: contribute around 40 horsepower-equivalent to the system

  • Combined system: approximately 343 horsepower (256 kW)


These figures reflect the original specifications for the 2007 GS 450h and are consistent with the model’s marketing and technical documentation. Real-world output can vary slightly based on market, battery state, and driving conditions.


Notes on model-year variations


While the 2007 GS 450h is commonly cited as delivering roughly 343 hp combined, some sources describe minor year-to-year variations in rating or battery-assisted performance. The overall takeaway remains that the hybrid setup pairs a capable V6 engine with electric propulsion to yield a total horsepower in the low-to-mid 340s, ahead of many non-hybrid peers in its segment at the time.


Summary


In sum, the 2007 Lexus GS 450h’s hybrid system totals about 343 horsepower, with a ~303-horsepower gasoline V6 providing the core power and the electric motors adding the remainder for a combined performance figure that underscored its competitive stance among luxury hybrids of that era.
