Page 1 of 1 The Lexus GS range has been comprehensively revised for 2008, the changes led by the introduction of a sophisticated and powerful 4.6-litre V8 engine in the new GS 460. Delivering a maximum 342bhp and matched to an eight-speed automatic transmission, it gives the GS stronger performance and more driving character than ever before.
The new engine benefits from Lexus's D-4S dual-port Fuel Injection, as used on the hybrid power GS 450h. It is the only system on the market to use two injectors per cylinder - one on the intake port, the other in the combustion chamber itself - delivering the advantages of both direct and indirect injection to maximise power and torque throughout the rev range.
The V8 is also equipped with Dual VVT-i, which is motor-driven on the intake valves for more effective performance at low engine speeds and oil temperatures than hydraulically controlled valve timing. It ensures prompt response and greater flexibility, with improved torque and fuel economy at all engine speeds.
The transmission is a version of the world's first eight-speed automatic, which made its debut on the LS 460 limousine. It is lighter and more compact than the six-speed transmission previously used on the GS 430, and is quieter and more fuel-efficient, too.
Thanks to the new powertrain, the GS 460 becomes the performance flagship of the GS range, cutting the nought to 62mph acceleration benchmark to 5.8 seconds; top speed is limited to 155mph. The efficiency of the engine and transmission enables the GS 460 to return an official fuel consumption figure of 25.7mpg in combined cycle driving, again improving on the performance of the previous GS 430 model. Carbon dioxide emissions are also reduced.
The GS 460 carries forward the comprehensive specification of the GS 430, including Variable Gear Ratio Steering (VGRS) and a Multimedia Pack that includes a 14-speaker Mark Levinson audio system, satellite navigation with dynamic route guidance, Bluetooth connectivity and a six-DVD autochanger.
