What's New for 2006

An all-new GS 430 debuts for 2006.


When the GS was first introduced in 1993, it was intended as a splash of scarlet in Lexus' inoffensive sedan lineup, as well as being Japan's answer to German sport sedans. It was an attractive car with an inviting interior. But as a sport sedan, the GS faltered, largely because of its size and underpowered 3.0-liter engine. Article after article called it a comfortable, competent handler that was seriously lacking a vibrant powertrain. Not content to take much flak over the competitiveness of its products, Lexus redid the car in 1998 with more dramatic styling and an available V8 engine. This V8 made the GS 400 one of the most powerful four-door sedans available at the time. An even more powerful V8 arrived in the 2001 GS 430.

For 2006, Lexus released a completely redesigned GS 430. Some hints of the previous GS shape carry over to the new car, especially up front. But most of the former ovoid proportions are replaced by taut surfaces and defined creases. The long, sloping roofline and very short deck create a pronounced fastback effect. Inside, fine materials, tasteful design and that impeccable touch the company does so well are still here. Although this car is new from its tires to its top, it's powered by the same 4.3-liter V8 that powered its predecessor -- a double-overhead-cam all-aluminum engine that makes 300 hp, mated to a new six-speed automatic. Overall, the new GS 430 boasts all the refinement you expect, plus edgy styling and crisp performance. It's the best sport sedan from Japan in its price range, and it may even be the best sedan in its class.

Body Styles, Trim Levels, and Options

This midsize four-door luxury sedan comes in just one trim level. Luxury touches include standard dual-zone automatic climate control, a power tilt and telescoping steering wheel, 10-way power front seats, an auto-dimming rearview mirror and an in-dash CD changer. Optional is an impressive-sounding Mark-Levinson audio system delivering discrete 5.1 multichannel playback, utilizing no less than 330 watts of amplifier power and 14 speakers. Other notable options include a navigation system, moonroof and ventilated front seats.

Powertrains and Performance

The GS 430 packs Lexus' 4.3-liter V8, the same one used in the LS 430. With 300 horsepower and 325 pound-feet of torque on tap, the car can accelerate from zero to 60 mph in about 6 seconds, a solid effort for this class. Variable Valve Timing with intelligence (VVT-i) is used to provide optimal fuel efficiency and allows the GS 430 to earn Ultra Low Emission Vehicle (ULEV) certification. A six-speed automatic is the only transmission available. Fuel mileage estimates are 18 mpg in the city and 23 on the highway. A variable-gear ratio electronic power steering system is standard.


Safety equipment includes front seat-mounted side airbags, full-length head curtain airbags, four-wheel antilock disc brakes with BrakeAssist, traction control and stability control. An optional Pre-Collision System (PCS), which is packaged with Dynamic Radar Cruise Control, uses a millimeter-wave radar sensor to detect obstacles in front of the car and a computer that reads vehicle speed, yaw rate and steering angle. If the computer determines that a collision is unavoidable, it preemptively stiffens the suspension, retracts the front seatbelts and preinitializes BrakeAssist so increased braking is applied the instant the brake pedal is depressed.

Interior Design and Special Features

A roomy cabin provides the driver and front passenger with space to stretch out. Impressive amounts of leg- and shoulder room easily accommodate the long-limbed and broad-shouldered. The cabin is outfitted with rich wood trim and handsome light-sensitive gauges housed in chrome-ringed pods. Materials quality is excellent, and everything is assembled with precision. Another nice touch is the hidden controls, evidence of the now legendary Lexus attention to detail. Company designers have hidden many of the lesser-used secondary controls -- like the power mirror switches and the dimmer switch for the interior lights -- into a retracting panel that hides itself away in the dash to the left of the steering wheel.

Driving Impressions

The GS 430 sparkles on the open road. With plenty of horsepower and torque on tap, the GS 430 accelerates briskly and it makes quick work of highway passing. Its silent cabin, devoid of any noise, harshness or vibration, is a portrait of tranquility. During cornering, the chassis is solid and the multilink suspension keeps the tires pressed tight to the ground at all times, while the computer-controlled steering feels nearly perfect. Too bad all the fun is tempered by an overly aggressive and undefeatable stability control system.

Mostly love this car

Vehicle: 2006 Lexus GS 430 4dr Sedan (4.3L 8cyl 6A)

This car is so fun to drive. I got a CPO last year with only 47000 miles. It is so amazing, how it rides. I actually giggled the first time I tried to pass someone on the freeway because I wasn't expecting it to speed up quite so merrily! Fun surprise! It feels so luxurious that I felt embarrassed to be driving it at first. Nobody deserves to drive in such luxury. It's just a blessing. :) The only complaints are that the dashboard squeaking will not cease. Lexus paid to fix it and it has been looked at about four times already but it cannot be fixed, even with that special fix they have. Also, a/c and park assist sensors have gone out and were fixed but the a/c took three times.

I purchased mine a Lexus Certified Used car, and all I can is "wow!" This car has just about everything a driver would need under the Sun. Once in gear, this car is like race horse ready to sprint out of the gate. The handling is excellent and very agile around corners and curves. One has to watch, however, the speedometer, as I found myself going from 40 to 80 in a few seconds.

I love my car - 3 years later there is not another car on the road that I want to drive. The only down side we have seen is that the brakes wear unreasonably quick - 20k miles or there about. That does not change my mind about the car - she handles oh so well!

Vehicle: 2006 Lexus GS 430 4dr Sedan (4.3L 8cyl 6A)

Bought this car from my son who put over 45k miles in less than 14 months. Read editor's model review which a lot better than consumer's ratings. Had a minor problem with tire warning coming on and not a very smooth ride. The dealer techs kept replacing the sensor in the tires and the warning would stay off for a couple thousand miles and I would have to go back in again. Well, to make a long story short the front struts were bad!! Although out of warranty Lexus replaced them and now it handles like a 60k car again. I own a small auto repair shop and you will not go wrong buying this car for around $30k :]

Nice car

Vehicle: 2006 Lexus GS 430 4dr Sedan (4.3L 8cyl 6A)

This is my second GS - the last was a 2000 GS 400. This car rocks - it is exceptionally comfortable to drive in, has an incredible stereo system and a truly amazing adaptive cruise control capability. On a recent 400+ mile drive, I averaged nearly 28.3 mpg - higher than the EPA rating!
