How much horsepower does a 2013 GS 450h have?
The 2013 Lexus GS 450h delivers a combined horsepower rating of 338 hp (253 kW).
The question concerns the power output of Lexus’s hybrid sedan for that model year. The GS 450h pairs a 3.5-liter V6 engine with electric motors to produce a total of 338 hp, a figure Lexus publishes for the vehicle’s performance credentials. The following sections break down what contributes to that rating and what it means for on-road performance.
Official horsepower rating
The combined horsepower figure reflects the joint output of the gasoline engine and the hybrid electric propulsion. The GS 450h blends internal combustion with electric motor power to achieve its total.
- 3.5-liter V6 gasoline engine
- Electric motors provide supplementary power and assist with drive, working to support the wheels as needed
- Continuously variable transmission (e-CVT) that blends outputs from both sources
- Hybrid all-wheel-drive system enabling power delivery to the wheels as conditions demand
In practical terms, the 338 hp rating comes from the synergy of the gasoline engine and electric propulsion rather than a simple addition of separate power figures. This setup is designed to balance smooth, quiet operation with strong acceleration when needed.
What the rating means for performance
For drivers, the 338 hp combined output translates to a refined, responsive feel typical of Lexus hybrids. The electric motors are able to provide immediate torque at low speeds, while the gasoline engine contributes sustained power at higher speeds. The result is a blend of efficiency and confidence-inspiring performance, especially in city driving and highway merges where hybrid assistance is most beneficial.
It’s important to note that real-world performance can vary with drive modes, temperature, and battery state of charge. The official rating remains the standard reference for the model year’s capabilities.
Summary
The 2013 GS 450h is rated at 338 hp in total, combining a 3.5-liter V6 engine with electric motors to deliver a balanced, capable hybrid performance package. The rating reflects how the system works together to provide both smooth power delivery and efficiency, rather than relying on a single-power-source calculation. For prospective buyers, this means a sedan that aims to offer refined acceleration with the benefits of hybrid technology.
