A brass thrust washer replaced the stock plastic unit in the transmission for enhanced reliability under racing stress, but no significant aerodynamic kits were applied, prioritizing the car's inherent grand touring stability over outright speed.[77] In 2003, the second-generation GS 400 was adapted for the German V8Star Series, a short-lived touring car championship featuring silhouette-bodied sedans on standardized tubular chassis. Prepared by Ryll Racing in collaboration with Roush Engineering, the Lexus GS entry driven by Ronny Melkus utilized a widebody kit to accommodate the series' regulations, providing a more aggressive stance and improved aerodynamics compared to the street model. Power came from a Roush-developed 5.7-liter pushrod V8 engine with two valves per cylinder, tuned to approximately 495 horsepower at 6,500 rpm and 600 Nm of torque at 4,850 rpm—significantly more than the production 4.0-liter 1UZ-FE's 300 horsepower. This engine, weighing about 200 kg in its lightweight aluminum block, was mated to a six-speed sequential gearbox for quicker shifts in competition. The silhouette design incorporated lightweight composite materials in non-structural panels to reduce overall weight, while racing slicks and upgraded brakes were standard for the series' high-grip demands. Street-legal features such as sound deadening and comfort-oriented suspension components were eliminated to focus on track performance.[78][79] Hybrid variants of the GS also saw limited racing adaptations, particularly with the third-generation GS 450h. A prototype entered the Super Taikyu endurance series in Japan in 2006, where the Hybrid Synergy Drive system—combining a 3.5-liter V6 engine with high-torque electric motors—was augmented for sustained high-speed output despite a weight penalty from the battery pack. This setup delivered over 340 combined horsepower, with electric motor assistance providing instant torque for corner exits, though the car finished fourth in class due to reliability challenges in 24-hour races. Chassis changes included reinforced mounting points for the hybrid components, lightweight racing wheels, and removal of luxury features like air conditioning to shave weight. No verified Bonneville Speed Week entries occurred, but the adaptation highlighted the potential of hybrid powertrains in motorsport.[80] Fourth-generation GS models had aftermarket adaptations inspired by Lexus's Super GT program. In Japan, select GS units were modified with aerodynamic enhancements such as carbon fiber diffusers, front splitters, and rear wings from tuners like TOM'S Racing, aimed at increasing downforce without altering engine outputs. These kits, often derived from GT300-class technology, improved high-speed stability. General racing preparations across GS generations emphasized lightweight materials like forged aluminum wheels and carbon composites where permitted, racing slicks for superior grip, and the elimination of street-legal amenities such as emissions controls and sound insulation to optimize weight and performance. In 2012, GS 350 models competed in Super Taikyu, with teams like Petronas TWS securing class podiums through strong reliability in endurance events.[81][82]Competition achievements
The Lexus GS marked its entry into competitive motorsport with the second-generation GS 400 in the Grand-Am Motorola Cup North American Street Stock Championship series. In its inaugural 1999 season, Team Lexus secured the team's first victory at Road Atlanta, with driver Chris Gleason at the wheel during the sixth race of the year. The effort culminated in championships for the team in the GT1 class that year and the following 2000 season, accompanied by multiple podium finishes across 1999 to 2001 that demonstrated the sedan's reliability and speed in stock-car format racing.[83][84] In 2003, the second-generation GS 400 debuted in European touring car competition through the V8Star Series, the first such outing for a Lexus model on the continent. Prepared by Roush and entered by Ryll Racing under Nitec sponsorship, the cars featured drivers including Ronny Melkus, Marco du Pau, and Steffen Widmann, achieving competitive results that included class podiums and highlighting the model's adaptability to silhouette racing rules. Altfrid Heger contributed to the series' efforts that season.[85][78] The GS also pioneered hybrid technology in endurance racing with the third-generation GS 450h. In July 2006, a near-production version entered by Toyota subsidiary Denso completed the Tokachi 24 Hours at Tokachi International Speedway—the world's first 24-hour race finish for a hybrid vehicle—placing fourth in the production car class and 17th overall in a 33-car field despite reliability challenges common to unproven hybrid systems. That same year, the GS 450h raced in the Super Taikyu Series' ST-1 class (over 3,501 cc), further validating its performance credentials in multi-hour endurance events.[86][87][88] Later iterations of the GS continued the model's racing legacy in Japan through the Super Taikyu endurance series, often serving as support events for Super GT rounds. The fourth-generation GS 350 achieved notable results in 2012, including class podiums. Across these and other series, the GS demonstrated reliability and performance in various motorsport formats.[89]Production and sales
Manufacturing locations
The Lexus GS was produced exclusively at Toyota's Tahara Plant in Aichi Prefecture, Japan, across all four generations from 1993 to 2020.[90][91] The facility, which began operations in 1979, serves as a dedicated hub for high-end Toyota and Lexus models, emphasizing precision assembly and quality control processes tailored to luxury sedans.[90] With an annual production capacity surpassing 396,000 vehicles for its luxury lineup, Tahara handled the full vehicle assembly for the GS, incorporating advanced robotic welding and human oversight to meet stringent standards.[91] The Japan-domestic Toyota Aristo, the equivalent of the first- and second-generation GS, was also manufactured solely at the Tahara Plant from its 1991 debut until production ceased in 2005.[92] Complete vehicle assembly remained centralized at Tahara to maintain consistency in build quality.[93] Annual sales volumes for the GS reached a peak of around 25,000 units in the mid-2000s, driven by robust global demand for the third-generation model, before tapering to fewer than 10,000 units by 2019 as consumer preferences shifted toward SUVs and crossovers.[25] The final GS sedan rolled off the Tahara assembly line in August 2020, marking the end of the model's 29-year run, after which the plant repurposed lines for increased production of the Lexus ES sedan.[94]Sales figures and market trends
The Lexus GS experienced varied sales performance across generations and regions, with the United States serving as its primary market. In the U.S., first-generation models (1993–1997) sold approximately 40,000 units, reflecting modest initial uptake in the luxury sedan segment.[25] Second-generation sales (1998–2005) reached around 120,000 units, bolstered by enhanced performance features and broader model options.[95] The third generation (2006–2011) saw stronger results at approximately 92,000 units, driven by the introduction of the GS 450h hybrid variant in 2006, which contributed to a sales boost amid rising demand for electrified vehicles.[96] Fourth-generation sales (2012–2020) totaled about 122,000 units but declined sharply post-2015, dropping to 3,378 annually by 2019 due to shifting consumer preferences toward SUVs and crossovers, which reduced overall sedan demand by over 50% in the luxury segment.[25][9][97] In Japan, where the model was initially marketed as the Toyota Aristo before the Lexus rebrand, sales fell amid competition from domestic rivals and changing buyer tastes.[98] The fourth-generation GS showed a brief resurgence in 2012 with over 6,000 pre-orders in its launch month, representing a significant portion of Lexus's total Japanese sales of 42,365 units the prior year.[98] Regionally, the GS struggled in Europe, with cumulative sales of about 75,000 units from 1993 to discontinuation in 2018; annual volumes remained low at under 1,000 units, leading to its early exit from the market. In contrast, China saw growth for the GS during the 2010s, supported by Lexus's overall brand expansion, though specific model volumes were modest compared to the more popular ES sedan.[99] Overall, the GS's market trends highlighted an initial strong position in North America, a hybrid-driven peak in the mid-2000s, and a later decline influenced by the global SUV surge, culminating in its global discontinuation after 2020.[100]Specifications
Engine options
The first-generation Lexus GS, produced from 1993 to 1997, featured a single engine option: the 3.0-liter inline-six 2JZ-GE, a naturally aspirated DOHC unit with variable valve timing (VVT-i introduced later in the lineup but not on this model), delivering 220 horsepower.[101] This engine provided smooth performance suited to the sedan's luxury-sport positioning, with no other variants offered globally during this period. The second-generation GS, spanning 1998 to 2005, expanded options starting with the carryover 3.0-liter inline-six 2JZ-GE engine, now rated at 225 horsepower in its initial form through 2000, before a minor detuning to 220 horsepower from 2001 onward due to updated emissions standards while retaining DOHC and VVT-i.[102][28] In 1998, a 4.0-liter V8 1UZ-FE joined the lineup for the GS 400, producing 300 horsepower via DOHC with VVT-i, emphasizing refined power delivery.[2] From 2001 to 2005, the GS 430 replaced it with the 4.3-liter V8 3UZ-FE, outputting 300 horsepower (some markets rated at 290 due to measurement differences), also DOHC with VVT-i for enhanced torque and smoothness.[103] No diesel engines were available for this generation worldwide. The third-generation GS (2006–2011) shifted to V6-dominant powertrains, beginning with a Japan-market-exclusive 2.5-liter V6 4GR-FSE for the GS 250 in 2006, an AWD-only DOHC direct-injection unit with dual VVT-i producing 208 horsepower.[104] North American models launched with the 3.0-liter V6 3GR-FSE in the GS 300 AWD (2006–2007), delivering 245 horsepower via DOHC, dual injection, and dual VVT-i.[2] From 2007, the GS 350 adopted the 3.5-liter V6 2GR-FSE, rated at 303 horsepower, featuring DOHC, direct/port injection, and dual VVT-i for balanced efficiency and output.[105] V8 options included the 2008–2011 GS 460's 4.6-liter 1UR-FSE, a DOHC unit with dual VVT-i producing 342 horsepower.[2] The GS 450h hybrid combined the 3.5-liter 2GR-FSE V6 with electric motors for a total system output of 340 horsepower, using DOHC and VVT-i on the gasoline component, available from 2007.[2] Diesel variants were absent globally. The fourth-generation GS (2012–2020) introduced turbocharging and refined hybrids while retaining V6 focus; early models (2012–2015) included the AWD-only 2.5-liter V6 4GR-FKS in the GS 250, a DOHC Atkinson-cycle engine with dual VVT-i producing 208 horsepower, primarily for select markets.[106] The GS 350 used the 3.5-liter V6 2GR-FKS, delivering 306 horsepower (2013–2015) or 311 horsepower (2016–2020) via DOHC, direct/port injection, and dual VVT-iW (wide-range intake adjustment).[106] From 2016 to 2020, a 2.0-liter turbocharged inline-four 8AR-FTS powered the GS 200t (later GS 300), offering 241 horsepower with DOHC, dual injection, and VVT-iW.[107] The GS 450h hybrid persisted with the 3.5-liter 2GR-FKS V6 plus electric motors for 338 total horsepower, DOHC with VVT-i on the engine.[106] The performance-oriented GS F (2016–2020) featured a 5.0-liter V8 2UR-GSE, naturally aspirated DOHC with dual VVT-i and high-compression tuning, producing 467 horsepower.[2] As with prior generations, no diesel options were offered internationally.Dimensions and chassis
The Lexus GS chassis architecture emphasized rear-wheel-drive dynamics across all four generations, with progressive refinements in rigidity and weight distribution to enhance handling precision. The first and second generations (1993–2005) utilized a dedicated platform derived from the Toyota Aristo, featuring a unibody construction with multi-link rear suspension and a wheelbase of approximately 110 inches, providing a balanced footprint for agile performance. By the third generation (2006–2011), the chassis adopted a new rear-wheel-drive layout with aluminum subframes to reduce unsprung weight and improve responsiveness, extending the wheelbase to 112.2 inches for greater stability. The fourth generation (2012–2020) shifted to the modular GA-L platform, supporting both rear- and all-wheel-drive configurations, with enhanced structural rigidity through additional spot and laser welds, maintaining the 112.2-inch wheelbase while optimizing packaging for improved interior space. Suspension systems remained consistent in core design throughout the model's run, employing a double-wishbone front setup paired with a multi-link rear arrangement to minimize camber changes and ensure composed ride quality. Adaptive Variable Suspension (AVS), which adjusts damping in real-time for Normal or Sport modes, became available as an option starting with the third generation, particularly on higher trims like the GS 460. The fourth generation refined this further with aluminum control arms front and rear, while the F SPORT package added firmer springs, thicker anti-roll bars, and adaptive damping for sharper cornering. Drivetrain layouts prioritized rear-wheel drive as standard, with all-wheel drive introduced for the first time in the third generation on V6 models (distributing up to 70% torque to the rear, adjustable to 50:50), expanding to more variants in the fourth generation. Transmissions evolved from 4- and 5-speed automatics in early years to 6- and 8-speed units in later models, with paddle shifters for manual control; hybrid variants like the GS 450h employed a continuously variable transmission (CVT) integrated with Lexus Hybrid Drive. Overall dimensions grew modestly over time to accommodate evolving safety and luxury standards, with lengths ranging from 189.2 to 192.5 inches, widths from 70.7 to 72.4 inches, and heights from 55.1 to 57.9 inches (AWD models slightly taller). Curb weights typically fell between 3,500 and 3,900 pounds for non-hybrid models, with hybrids adding 200–300 pounds due to battery packs. Braking systems featured ventilated discs at all four corners across generations, with 4-piston aluminum calipers on front wheels for higher trims; the GS F variant included torque-vectoring differential and larger rotors for enhanced traction. Wheel sizes progressed from 16–17 inches in early generations to 17–19 inches in later ones, shod with performance-oriented alloys, such as staggered 19-inch setups on fourth-generation F SPORT models.| Generation | Wheelbase (in) | Length (in) | Width (in) | Height (in) | Curb Weight (lbs, approx.) |
|---|---|---|---|---|---|
| First (1993–1997) | 109.4 | 194.9 | 70.7 | 55.1 | 3,500 |
| Second (1998–2005) | 110.2 | 189.2 | 70.9 | 55.9–56.7 | 3,685 |
| Third (2006–2011) | 112.2 | 190.0 | 71.7 | 56.1 (RWD); 56.7 (AWD) | 3,700–3,800 |
| Fourth (2012–2020) | 112.2 | 190.7–192.5 | 72.4 | 57.3 (RWD); 57.9 (AWD) | 3,600–3,900 (hybrids +200–300) |
