I don't know about you guys, but I really felt Lexus was too conservative with the last IS. It didn't have the uniqueness about it that drew me to the first-generation car, and by the end of its run, even the monster-motor'ed IS-F was hardly worth a second glance. Lexus has flipped the switch on the new IS350, and with the F-Sport package, has created the most aggressive front end this side of a Lamborghini Aventador. Some hate it, but I applaud them for "going bold or going home" at a time when ze Germans are taming their designs down. But the question is, how does it drive? We took one on Southern California's most challenging road to find out.
