Lexus GS430

Introduced in 2001 as a third generation update of Lexus’s high-performance midsize GS line, the Lexus GS430 was powered by a 4.3-liter V-8 with 300 horsepower. As it spent two years as the brand’s most powerful premium sport sedan, it was replaced in 2003 with the even more capable GS460, which housed a 4.6-liter V-8 producing 342 horsepower.

Lexus GS430 Origins

The GS430’s 4.3-liter powerhouse, which is the same engine found in the higher-end LS430, produced 325 lb-ft of torque at 3400 rpm. In comparison, the V-6-powered Lexus GS300 produced just 245 horsepower. Performance-enhancing variable valve timing and a sport suspension also set the GS430 apart from its six-cylinder counterpart. Early models came with a five-speed automatic transmission. A six-speed automatic was added in 2006.

When the GS430 was released, it introduced a stylish new design for the GS line. Notable changes included a longer and sleeker cabin, a sloping fastback-style roof, an elegantly curved front end with quad headlights and larger grille, and a trimmer back end with spoiler.

A number of features debuted along with the GS430, including water-repellent door glass, standard side curtain airbags, stainless steel-tipped exhaust pipes, and six-spoke alloy wheels.

About the Lexus GS430

Per usual for GS models, the rear drive GS430 was best known as a premium sport sedan blending refined luxury with pure power.

An engine capable of 300 horsepower and 325 lb-ft of torque helped the GS430 go from 0-60 mph in an estimated six seconds, putting it on par with four-door European sport sedans like the Mercedes E-Class and BMW 5 Series. Variable valve timing kept fuel economy to a respectable EPA-estimated 16/23 mpg city/highway.

In addition to a long list of standard luxury amenities ranging from leather upholstery to dual-zone automatic climate control, the GS430 came equipped with new high-tech features such as collision-sensing door locks and a power tilt-and-telescopic steering wheel that moved out of the way when the door was opened.

A spacious front cabin and conveniences like a heated driver seat made the Lexus GS430 a comfortable commute vehicle, while five seats and 12.7 cubic feet of cargo space provided enough room to accommodate a family.

Lexus GS430 Features

Lexus produced the last GS430 in 2007, though the succeeding 2008 GS460 was identical save for a larger 4.6-liter V-8 engine.

The 2007 Lexus GS430 was equipped with the model’s standard all-aluminum 4.3-liter V-8 engine and a new six-speed automatic transmission. Most exterior features were carried over from a 2006 redesign, including a longer cabin with fastback profile, sharper creases on the sides and hood, and a short, sporty rear deck.

Standard features on the single-trim 2007 GS430 included 18-inch alloy wheels, wood and leather trim, leather upholstery, 10-way power front seats, a multi-level heated driver seat, heated and powered mirrors, a tilt-and-telescopic steering wheel, audio and cruise steering wheel controls, dual-zone climate control, and a 10-speaker audio system with a 6-disc CD changer. Optional upgrades included a power sunroof, ventilated front seats, touchscreen navigation system, and a premium Mark-Levinson sound system with 5.1 multichannel playback.

Safety equipment on the 2007 model included full-length head curtain airbags, front seat-mounted side airbags, antilock disc brakes, child seat anchors, and traction and stability control. Buyers could add an optional pre-collision system that prepared the vehicle for imminent accidents by tightening front seat belts and stiffening suspension.

The spacious front cabin allowed for 37.8 inches of head room and 43.5 inches of leg room. Rear passengers received 37 inches of head room and 36.4 inches of leg room. Available cargo space was 12.7 cubic inches.

Lexus GS430 Evolution

The Lexus GS430 debuted in 2001 as a restyled update of the GS400. In addition to a more aggressive 4.3-liter V-8 engine, the GS430 introduced a sportier fastback profile, new front end, bigger grille, and shorter rear deck with new taillights. Other new features in 2001 include standard side curtain airbags, child seat anchors, impact-detecting door locks, HID headlights, steering wheel audio controls, six-spoke alloy wheels, and larger exhaust pipes tipped with stainless steel.

Options at the time included a DVD-based navigation system, premium Mark Levinson audio system, and a wood and leather steering wheel. In 2003, Lexus added several additional options, including heated front seats, a CD changer, and a sunroof. Leather seating became standard.

Lexus restyled its GS series again for 2006. The 2006 GS430 traded its formerly ovoid body for an even more dramatically sloped fastback roof, a more elegantly curved hood, and crisper creases. Standard interior features still included luxuries like leather seats and wood trim on the console, doors, shift knob, and steering wheel. A retracting panel was added to conceal lesser-used controls on the dashboard.

In 2007, an optional active stabilizer was added to reduce body roll on tight corners and a Lexus Link telematics system was made standard. The stability control system was also modified to improve driver control.

For 2008, Lexus changed the sedan’s name to the GS460 in conjunction with the addition of a 4.6-liter V-8 engine. However, the vehicle itself remained largely similar to the 2006 and 2007 GS430s.
