inside and out. Aside from the rear badge, only new 5-spoke 18-inch alloy wheels are unique, while on the inside the standard tachometer is replaced by a power meter that displays the total output of the combined powertrains. As the vehicle comes with a standard TFT dashboard display, the hybrid system's activities are displayed like a flow chart, as on the Prius, Highlander Hybrid Limited and RX 400h.

With the GS 450h upping the ante on the GS range, there's a good chance that the entire Lexus GS range will be revitalized in accordance to this. Currently, the GS 430 is powered by the well-seasoned

4.3-litre V8, which has served Lexus for many years, however, the latest 3.5-litre V6 used in the new IS 350 exceeds its power output. It has been speculated that the engine's successor will be a 4.6-litre V8 with 350-horsepower, or more. Also, despite the fact that 250-horsepower is merely adequate in this day and age, for a premium luxury car at least, Lexus will most likely replace the GS 300's 250-hp 3.0-litre V6 with the aforementioned 306-hp 3.5-litre V6.

The GS 450h is expected to arrive in showrooms in early spring 2006, and, if our estimates are correct, will command a $5,000 premium over the GS 430 model. In the mean time, keep posted to this space; expect a significant update filling in the critical gaps about the hybrid drive system, plus specific price and equipment should come early in the New Year.
