Lexus unveils 2013 GS 350 F Sport ahead of SEMA

Over at Lexus, F stands for performance. Think F as in LFA. Think F as in IS-F. And think F as in F Sport, the series of kits that ever so subtly change a Toyota luxury vehicle's attitude from sedate to sporty. So if you thought the new Lexus GS sedan could use a shot of adrenaline, we've got good news for you, as Lexus has just revealed a new F Sport package for the GS 350 that will make its debut next week at SEMA.

The package encompasses a new set of 19-inch wheels, sport-tuned adaptive suspension, thicker anti-roll bars, new bushing, and bigger brakes up front. Variable steering is also included for rear-drive models, while the interior gets a new driver's seat, unique trim and available red leather.

Cap that off with a more aggressive aero kit and the GS is transformed, if not into an outright performance sedan – the 3.5-liter V6 remains unchanged, after all, at 306 horsepower – then into something a little more aggressive than what you'd expect to see in the local diner parking lot at five p.m. Check it out in the press release after the jump and the high-res images in the gallery for a closer look.
