2009 Lexus GS450H Review

High-performance sedan with optimal fuel economy.

Reviewed by Automotive on


Lexus fine-tunes and reintroduces the GS450H for 2009. Equipped with a hybrid powertrain that combines 3.5-liter V-6 with an electric motor system that generates 340 horsepower, the GS450H is a performance-oriented sedan especially for those who navigate serious weather. It joins the Lexus GS lineup with V-8 engines and V-6 hybrid powertrain sedans as an alternative to the comfort-focused ES350.

What's New

Lexus expands the GS lineup with the 2009 GS450H for those demanding a high performing and fuel-efficient sedan. The GS450H outperforms the bigger V-8 engine and uses about a third of the gas according to Lexus. The 2009 GS450H is all rear drive, but it also holds another perk standard for all GS models, the VDC electronic stability control.

A Pre-Collision System is optional. With radar sensors, the computer determines when a collision is unavoidable and anticipates impact with seatbelt retraction, stiff suspension, and a ready brake assist. It also applies a measured amount of brake pressure to mitigate damages if a driver fails to brake before impact.

Standard on the GS450H, and optional on other models, the Adaptive Variable Suspension system incorporates four settings including a softer comfort focused more on a spectrum with the opposite end being a sport mode for high performance driving.

GS460 and GS450h models improve with the Vehicle Dynamics Integrated Management system, which combines the extended list of standard electronic safety and performance technology--including the anti-lock brakes, brake assist, electronic brake force distribution, and variable-ratio steering for an exceptionally smooth ride.


With its four-door class of sedans, the well-rounded and high performance 2009 GS lineup cruises in any weather and creates an almost childlike cheer in its driver. Lexus offers an affordable base with a gorgeous GS450H engine and adds the sleek design and attractive grille and the GS450H is an irresistible ride


Maneuverability is paramount in the 2009 Lexus GS450H due to its low, compact, and relatively light weight. The trunk capacity is relatively small so toting capability is limited. Backseat passenger seating continues to be tight. Lexus GS models feature leather upholstery, 10-way adjustable power seats, dual-zone automatic climate control, a power rear sunshade, and a 10-speaker sound system with in-dash 6-CD changer. Interior decoration styles and materials vary, including Walnut, Dark Gray, or Brown Bird’s Eye Maple trim, and a broad spectrum of leathers.

Other sound options include a Mark Levinson Premium Audio system with a 330-watts amplifier, 11 channels, and the capability to play multi-format, multi-media CDs or DVDs on the included screen and a DVD-based navigation system with Bluetooth interface and hands free operating system.

Performance & Handling

The base 2009 Lexus GS450H and its hybrid powertrain combine a 3.5-liter V-6 with an electric motor system propels the vehicle. The torque and all-wheel drive capabilities are able to handle almost any obstacle the weather put in the driver's way. The 2009 Lexus GS450H is also a capable cruiser, the suspension gliding over road troubles with minimal engine, road, and wind noise. The GS450H’s small size and responsiveness promotes maneuverability, but the trunk size limits toting capacity and a lack of safety ratings by the National Highway Traffic Safety Administration makes it a bit of a wild card.


The 2009 Lexus GS450H comes standard with four-wheel anti-lock braking system and regenerative braking. It also includes electronic brake force distribution with brake assist and vehicle dynamics integrated management and electronic-controlled braking. Other standard safety features include vehicle stability control, traction control, front and rear crumple zones, daytime running lights, dual-stage front airbag system, front and rear mounted side impact airbags, front and rear side curtain airbags, intuitive parking assistance; a backup camera, all-position three-point seat belts including outboard pretensions with force limiters, height adjustable front shoulder belt anchors, all-position emergency locking retractor, all-passenger automatic locking retraction, child safety rear door locks, direct tire pressure monitoring system, impact reducing upper interior trim, and a brake pedal regression mechanism.
