2006 Lexus GS300 Review

One of the best midsize luxury sedans on the market.

Reviewed by Automotive on


The Lexus GS model was originally introduced in 1993 to compete with the German-dominated sedan market. However, this early incarnation of the GS failed to perform to the same standards as its German counterparts, due to its underpowered engine and large size.

Many improvements were made over the years, including a V-6 engine introduced for the second generation in 1998. All of the changes, however, led towards the Lexus GS300.

The 2006 GS300 is a major improvement over previous Lexus models. First, the weight is down significantly, due to the light alloy engine. Although not as powerful as the V-8, it has less weight to drag around, making it that much more capable. The alloy V-6 replaced the previous inline V-6 which didn’t have as much horsepower as the new engine.

Inside, the 2006 Lexus GS300 is supplied with lots of luxurious standard features. Everything is tastefully designed, making for a very pleasant ride all around. The 2006 Lexus GS300 doesn’t just outdo the previous incarnations of the GS model, it is also a major competitor in the sedan marketplace.

What's New

The Lexus GS300 debuted for the first time in 2006.


The 2006 Lexus GS300’s standard, exterior features include 17-inch alloy wheels fitted with all-season tires, variable intermittent windshield wipers, a rear defogger, daytime running lights, auto-delay off headlamps, dusk sensing headlamps, Xenon high-intensity discharge headlamps, heated mirrors, and power mirrors and windows.


The interior of the 2006 Lexus GS300 is very roomy with 43.5 inches of front legroom and plenty of shoulder room. The rear seat also has a lot of room, and 12.7 cubic feet of cargo space is available.

The interior is very attractive. There is plenty of wood trim on the dash, doors and center console. Everything is wrapped in leather. All the gauges are well designed and are light sensitive, dimming and brightening as ambient light conditions brighten or weaken. A retracting panel has been included to hide some power accessories that are used less often, such as controls for the power mirrors and the interior light dimmer. This keeps the interior from feeling too cluttered.

Other standard features include cruise control, a tilt steering wheel, audio and cruise control steering wheel mounted adjustments, front seatback storage, 10-way power driver-seat adjustments, eight-way power passenger seat adjustments, lumbar support, memory settings, bucket front seats, electric speed proportional cruise control, an air filter, and a 134-watt, 10-speaker audio system.

Performance & Handling

The 2006 Lexus GS300 uses a three-liter displacement, light-alloy V-6 that reduces engine weight by 100 pounds. The V-6 produces 245 horsepower with 230 lb-ft of torque at 3600 rpm. The engine is wed to a six-speed automatic transmission system. The automatic has manual upshift and downshift controls that allow you to take advantage of all six gears. An all-wheel-drive system is also available.

The 2006 Lexus GS 300 is a real gem on the open road. The cabin is silent while the driver barely hears the engine running. The suspension is independent and is multi-linked, meaning you get the smoothest ride possible. The V-6 is very quick to accelerate and doesn’t struggle at speed with the handling nearing perfection.


The 2006 Lexus GS300 is abundant with safety equipment. The interior is equipped with seat-mounted front airbags, full-length curtain airbags, four-wheel anti-lock brakes with the BrakeAssist system, and traction and stability control. An optional Pre-Collision system is offered with Dynamic Radar Cruise Control. The Pre-Collision system uses a short wave radar system to detect when there is an obstacle in front of your vehicle. The Dynamic Radar Cruise Control detects when there is a car in front of you and adjusts your speed automatically to avoid collision. The Pre-Collision control will stiffen the suspension of the vehicle, retract the front seat belts, and initializes the BrakeAssist system to prevent injury during an unavoidable collision.
