Unfortunately Lexus hasn't graced us with the specifics of the new GS's F Sport package, but from the photos we can see that, as usual, the F Sport treatment includes a full appearance tweak courtesy of revised bumpers, new wheels, and other small details. The interior of the car likely wears more F Sport upgrades.
There's a chance Lexus will also be including a suspension upgrade as part of the F Sport tweaks. Power is expected to stay put, however, as are brakes and other performance elements.
Check out the gallery below and stay tuned for the full details as soon as Lexus releases them.
