2011 Lexus GS450H Review

Excellent hybrid-powered luxury midsize sport sedan that delivers the performance of a V-8, with the fuel efficiency of a V-6 family sedan.

Reviewed by Automotive on


The 2011 Lexus GS450h is more of a performance-based hybrid than the typical models on the market. Most of the competition primarily focuses only on making the fuel consumption less and performance takes second in the design. This is not the case with the Lexus GS450h. It runs on the combined gasoline engine and electric motors, but with the 292 horsepower under the hood from the 3.5-liter V-6 coupled with 340 hp from the electric motors, it proves extremely powerful.

The fuel economy remains decent with an estimated combined fuel rating of 23 mpg, though in comparison to others on the market fuel economy does not attract buyers. The spirited acceleration of the engine draws them in. Also, the hybrid GS 450 remains a bit more expensive without the traditional hybrid benefit of lowering fuel consumption. For a luxury sedan it delivers low fuel usage and high-performance capabilities.

What's New

The 2011 Lexus GS450h carries on unchanged from previous years.


The 2011 Lexus GS450h continues to provide an elegant, sporty looking hybrid vehicle that offers many features in a single trim level. Standard features on the luxury sport sedan include adaptive automatic xenon lights, rear and front parking sensors, a rear-view camera, a power-operated rear sunshade, and 18-inch alloy wheels. Performance tires come standard, along with the adaptive variable suspension.

Exterior options can be chosen additionally, if desired. These include a rear spoiler and the run-flat tires. The advanced suspension provides another option that requires the use of run-flat tires.


Lexus enjoys a reputation for incorporating finely crafted interiors into its vehicle lineup and the 2011 GS450h offers further proof. The cabin surrounds its occupants with rich wood, supple leather, and aluminum trim. Standard interior features include an audio system with a six-disc CD changer and 10 speakers for a completely entertaining audio experience. Ventilated and heated front seats come standard, as does automatic dual-zone climate control.

Performance & Handling

With up to 340 hp generated by the combination of the two electric motors and the 3.5-liter V-6, the 2011 Lexus GS450h feels extremely powerful. The continuously variable transmission sends the power towards the rear wheels. The full-hybrid GS450h can operate under electric power for a small distance and seamlessly engage its V-6 whenever it needs more motivation. The performance of the vehicle seems impressive no matter which mode it operates in and provides the same abundant power reserves of a V-8-powered sedan.

For acceleration, Lexus estimates that the GS450h goes to 60 mph from a standstill in a very short 5.2 seconds. When test driven, the car provides a very comfortable ride and stops quickly. Switching the modes allows a more customized driving experience.

With the Comfort mode the car serves a soft, smooth ride and switching to the Sport mode provides more responsive and stiffer dynamics. For the most spirited drivers, the Active Power Stabilizer significantly reduces the danger of body roll when taking corners.


Standard safety features for the 2011 Lexus GS450h include traction control, front knee airbags, side-impact airbags in the front and rear, stability control, front head restraints, and side curtain airbags.

The telematics service called Safety Connect also comes standard on the GS450h. The system has a stolen vehicle locator, automatic collision notification, and an emergency assistance button for convenient use when an accident might have occurred. Additionally, the adaptive cruise control that remains optional on the Lexus GS450h includes a system that detects impending collisions. The pre-collision system responds by activating brake assist and tightening up the seat belts in preparation for a crash.

The GS450h receives a ?Good? rating, which marks the highest rating, from the Insurance Institute for Highway Safety in side-impact and frontal-offset collisions. The government has not yet rated the vehicle since the newer procedures of crash testing began in 2011.
