Lexus has already faked out the spy community, through which word of a V8 powered Lexus IS spread like Influenza A virus subtype H5N1. Through them, we'd heard the so-called IS 500 would debut at the '06 Detroit show, which came and went without word one that such a car was in the pipeline. Now, the spooks have caught sight of what they believe is the IS 500 in apparent shakedown testing on the N rburgring. Could Detroit '07 be the venue for the hi-po Lexus S4/M3 fighter? Only agent Ken Watanabe (and a few of his henchmen) know for sure.
