context_page_description: The Lexus GS (S190) is the third generation of the Lexus GS line of executive cars. Sold by Lexus since 2005, the line includes multiple V6, V8, and hybrid models. A concept model for the GS line, the LF-S, debuted in late 2003 at the Tokyo Motor Show. The third generation GS first appeared as a pre-production vehicle at the 2004 North American International Auto Show in Detroit with the production version being shown a year later at the 2005 show. The initial lineup featured V6 and V8 engines with rear-wheel drive, and for the first time on a Lexus sedan, the option of all-wheel drive with the V6-powered GS 300 and GS 350 models. The GS 450h performance hybrid joined the lineup in 2006.
  The production GS was built on a newly designed mid-size platform which would also be used on the second-generation IS. Production of the third generation began on 24 January 2005 in the city of Tahara, Aichi, in Japan, where all GS models would be built. The third generation GS was also the first model to feature Lexus' own L-finesse styling upon its introduction.
context_section_description: In September 2005, the GS 350 (GRS191) and GS 430 (UZS190) went on sale in Japan; the GS 350 using a 3.5-liter 2GR-FSE engine with D4-S direct injection, while the GS 430 used the same 4.3-liter 3UZ-FE V8 used in the previous model. Sales in the United States began in March 2006 as a 2006 model, with the initial U.S. model lineup including the GS 300 (GRS190), featuring a ULEV certified 3.0-liter 3GR-FSE V6 engine, and the GS 430. The GS 300 featured a D4 direct-injection fuel system for all markets except Continental Asia, excluding Singapore, becoming Toyota's first vehicle equipped with direct injection sold in the United States. The 3.0-liter engine was also found in the Toyota Mark X as well as the Zero Toyota Crown, however the new GS 300 was never offered in the Japanese market. The GS 300, GS 350, and GS 430 engine options were paired to a new 6-speed automatic sequential shift gearbox. An all-wheel drive system was made available in the GS 300, thus becoming the first Lexus sedan to offer such a configuration; the system varied the front/rear wheel torque split anywhere from 50/50 to 30/70 depending on conditions.
  Also new to the GS line was an Electric Power Steering (EPS) system replacing the previous model's hydraulic steering pump, while the V8 model featured a Variable Gear Ratio Steering (VGRS) system and Electronically Controlled Brake (ECB) a type of brake-by-wire system. In August 2005, the GS 430 was the first car by Toyota with Adaptive Variable Suspension (AVS). AVS monitors and adjusts the shock-absorber settings at each wheel, depending on the conditions. On rough roads, for example, damping is reduced for a more comfortable ride. And, while cornering, the suspension is tightened to help reduce body lean and provide even greater responsiveness. Using the EPS system the GS can automatically compensate for crosswinds.
  For the 2007 model year, the GS 350 replaced the GS 300 in the U.S. and other export markets. Due to a change in SAE testing procedures, the 2007 GS 430 horsepower rating was reduced from 300 to 290 (with 319 lb⋅ft (433 N⋅m). of torque), while the V6-powered GS 350 was rated at 303 hp (with 274 lb⋅ft (371 N⋅m). of torque). Lexus reported 0-60 times of 5.7 seconds for both vehicles. For 2008, the GS 350 came with Vehicle Dynamics Integrated Management (VDIM), which was previously standard only on V8 and hybrid models. The Adaptive Variable Suspension (AVS) was now an option on the V6 model as well.
  In 2007, Consumer Reports predicted reliability survey blamed the 2006 first-year GS in the all-wheel-drive form, which had problems in integrity (rattles), body hardware and sound system, as the sole reason for lowering Lexus' overall score. Despite the reliability issues among 2006 GS models, the vehicle earned a "Recommended" rating from Consumer Reports for vehicle features, overall value and previously automatically assumed reliability for that year. However, the problems have apparently been solved, and the GS AWD was rated "average" in later years.
