Just noticed this on wikipedia about 2007 GS ....................
[edit] Third generation (2006-present)
Third generation
Production: 2006–present
Engine: 3.0 L V6 3GR-FSE
3.5 L V6 2GR-FSE
4.3 L V8
The third generation GS was first sold in 2005 as a 2006 model, with the chassis codename GRS190. The model lineup included the GS 300, with a 3.0 L V6 3GR-FSE engine, and the GS 430 with the same 4.3 L V8 used in the previous model. The GS 300 has a direct-injection engine for all markets except for Continental Asia. The 3.0 L engine is also found in the Toyota Mark X as well as the Zero Toyota Crown. A 4WD option was made available in the GS300 only.
A GS 350, using the 3.5L 2GR-FSE engine, replaced the GS 300 for the 2007 model year. Due to a change in SAE testing procedures, the 2007 GS 430 horsepower rating was changed to 290 (with 319 ft-lbs. of torque) , while the V6-powered GS 350 was rated at 303 horsepwer (with 274 ft-lbs. of torque). Lexus reports 0-60 times of 5.7 seconds for both vehicles. A 4.6L GS 460 is expected to replace the 4.3L GS 430 by 2008. Production of the 3rd generation began on January 24, 2005.
The equivalent Aristo was not released as Toyota sought to align all world markets, including Japan, using Lexus as their premium brand worldwide.
The third generation GS was the first Lexus model to feature the marque's new L-Finesse design philosophy, characterized by swooping lines, a pulled-back cabin, and more muscular styling. The vehicle also premiered the latest generation of Lexus' SmartAccess keyless system--adding a push-button start for the first time. Other unique features included a driver-side hidden panel for infrequently used controls, a standard touchscreen display in the center console, LED lighting in the cabin, and Bluetooth technology.
