When Lexus introduced the IS F, enthusiasts were suitably skeptical about the automaker's attempt to go head-to-head with the Germans. After all, Audi, BMW and Mercedes-Benz have specialized in creating autobahn-burning, Nordschleife-honed handlers for decades.

And then we drove it.

To everyone's surprise, Lexus pulled it off, but we figured it might be a one-time deal. We assumed the IS F was an outlier – just a distraction from the brand's cadre of well-built, less-than-sporty luxo-barges. We were wrong.

In the footsteps of the IS F was the introduction of the F-Sport accessories line, followed by rumors of a GS F and finally the LFA supercar. Lexus was becoming increasingly serious about making a mark in the luxury performance space, but on its own terms and at its own calculated pace.

Flash forward to October when a press release arrived touting a new Sport Package for the upcoming 2010 LS460. To be honest, our first thought was Lexus was overreaching. The LS is a fine sedan, with plenty of power and a reasonably good balance of ride and handling. But a sports sedan it's not. No matter. If Lexus was threatening to "F" up its LS with a "Sport" package, we needed to put it to the test. And we did just that.
