F, now there's a letter that says high performance, don't it? Lexus must have figured that all the good ones were taken, so why not just go with the first letter of FAST. No doubt, the GS-F will be a rocket. It better be, if it wants to try kicking sand in the face of the M5. The artist's rendering gives a credible estimation of what kind of styling *ahem* enhancements might accompany the increased athleticism in the GS's chassis, and the increased power under the hood. We guess that the GS-F will need to call some attention to itself to help build street cred, but if the actual car looks anything like the rendering, there'll be no stealth bombing for you.
