(August 4, 2011) TORRANCE, Calif. — Lexus will reveal the all-new GS 350 mid-size luxury sport sedan on Thursday, Aug.18, in conjunction with the Pebble Beach Concours d’Elegance.

The fourth-generation GS has been completely redesigned, inside and out, and will feature the brand’s new design philosophy, with styling cues such as a distinctive new front grille, that will soon be seen on all future Lexus vehicles. The new GS will also lead the rest of the Lexus lineup in an entirely new direction of driving dynamics.

“Today, buyers in the mid-size luxury segment want a more engaging driving experience, styling that makes a statement, and a roomier interior package,” said Mark Templin, Lexus group vice president and general manager. “With the all-new GS, we’re giving them what they asked for, and more.”

Lexus gave no other details and released the teaser picture above that looks like the front end of an Audi model. We will have to wait a couple of weeks to get full disclosure.
