Lexus has updated its GS range with the new Lexus GS460, which launches with the luxury sedan line’s 2008 mid-life revision. The Lexus GS460 uses the LS460’s 4.6 litre V8, and features D-4S dual-port fuel injection which uses two injectors per cylinder – one on the intake port, the other in the combustion chamber itself â€“ delivering the advantages of both direct and indirect injection to maximise power and torque throughout the revs.
The V8 also uses Dual VVT-iE, which uses a motor-driven valve timing system for the intake valves instead of the usual hydraulically controlled system. It produces 342 horsepower at 6,400rpm and 460Nm of torque at 4,100rpm. The engine is mated to the AA80E 8-speed automatic transmission also found on the LS460, which despite its larger amount of ratios, is actually more compact and lighter than the GS430’s 6-speed transmission. It is also quieter and fuel efficient. 0 to 100km/h takes 5.8 seconds, and fuel consumption is rated at 9 litres of fuel per 100km on a combined cycle.
As for the facelift’s styling updates which also apply to the rest of the GS range, there is now a chrome surround for the front grille, new door mirrors with integrated indicators and new-look door handles. The front and rear bumpers have also undergone a minor restyling exercise, with new-shape air intakes. New 17-inch (GS 300 and GS 300 SE) and 18-inch (GS 300 SE-L and GS 460) wheel designs have been introduced and the GS is available in two new colours now – Byzantine Silver and Namibian Gold.
On the inside, the steering wheel mounted audio and telephony controls have been updated, and the boot and fuel filler release buttons have been relocated outside the little pop-out module that Lexus employed to keep the dash design cleaner without too many exposed buttons.
