According to the latest issue of Motor Trend (September 2007, Volume 59, Number 9), and in an article about new car buyer's guide, they mentioned this:
Lexus IS/IS-F:"...The first offering in the new Lexus F-series of ultra-perfomance cars, expect the IS-f to have 400-425-hp version of the 5.0L V-8 from the LS 600h, eight-speed paddle-shifted automatic, Brembo ABS discs, ..."
Lexus GS: "Big changes for the entire GS series, headed by the new GS460 that replaces the GS430 and packs a 342-hp/4.6L V-8. On the Hybrid front, the GS450h adds a positive VDIM/VSC cutoff. All GS models get revised front fascias, wheels, and colors, plus numerous interior trim tweaks in cluding new gauges. The GS460 also boasts heated/ventilated seats."
They also described and the IS-F as "driver's choise" and the GS350 as a "best buy".
So how accurate you guys think that article is, because I have heard from other sources that the IS-F will have something between 438-445-hp, and that the GS460 will have at least 358-hp?
