GS 450h Offers V8-Like Performance with Low Emissions
* 340 HP Total Output with Combined 23 MPG Ratings
* Powerful Torque Provides Smooth Acceleration
* Seamlessly Blends Refinement and Sportiness
After receiving stylish exterior changes in 2010, the GS 450h enters the 2011 model year as one of the most refined hybrid luxury sport sedans available today with a myriad of convenience features. The GS 450h features impressive fuel economy ratings for the smooth and powerful acceleration it provides. In its fifth model year, the GS 450h continues to be a favorite fun-to-drive vehicle.
Engine/Transmission/Drivetrain/Performance
Based on the GS platform and featuring Lexus Hybrid Drive technology, the GS 450h offers V8-like performance with greater fuel efficiency. In addition to boosting performance and fuel efficiency while lowering emissions, Lexus Hybrid Drive technology also further accentuates the brand’s renowned smooth, quiet operation.
As a full hybrid, the GS 450h is capable of operating in gas-only or electric-only modes, or a combination of the two. With its unique transmission, the GS 450h was the first hybrid vehicle to enable the electric drive motor to contribute to highway performance, not just slow-speed driving.
The GS 450h model’s version of the Lexus Hybrid Drive powertrain combines a powerful 3.5-liter V6 engine with a compact, permanent magnet electric motor – all driving the rear wheels. The hybrid powertrain collectively produces 340 horsepower and can effortlessly accelerate the GS 450h from zero-to-60 mph in just 5.2 seconds.
Just as impressive as the GS 450h’s acceleration from a stop is how quickly and powerfully torque is delivered during mid-range acceleration. The hybrid system’s electric-drive motor delivers maximum torque immediately upon demand. This unique power-delivery characteristic is most noticeable, and most useful, during 30-to-50 mph passing and in traffic-merging maneuvers. The GS 450h returns EPA-estimated fuel economy of 22 mpg city/25 highway/23 combined and is certified as a Super-Low Emissions Vehicle II (SULEV II).
The gasoline V6 uses an Electronic Throttle Control System with intelligence (ETCS-i) and a dual fuel-injection system that combines the benefits of direct injection with those of port injection. Dual Variable Valve Timing with intelligence (VVT-i) operates on the intake and exhaust valves to further enhance power and torque across a broad engine speed range.
The GS 450h hybrid powertrain uses two motor-generators, MG1 and MG2 (the drive motor). Each performs specific functions and can operate as both a motor and a generator, although MG1 is used as a starter motor and provides no motive force. The engine-driven generator (MG1) can charge the battery pack or provide additional power to MG2 as needed.
