Lexus showed off its new GS 350 sedan Thursday at Pebble Beach in California. The completely redesigned GS will hit dealerships in early 2012 as a 2013 model.

The 2013 GS 350 gets a new exterior and chassis as well as updates to the interior. “While leaving exterior dimensions virtually unchanged, they (engineers) dramatically increased cabin and trunk space to create an interior that can easily transport passengers and their luggage in luxury and style regardless of distance,” Lexus says in a press release. Lexus says the exterior design was based on the Lexus LFA sports car.

“The 2013 GS 350 may not be quite the leap forward we were hoping it would be, but it promises to be a better contender than its oft-forgotten predecessor,” Motor Trend reports.

The rear-wheel drive 2013 Lexus GS 350 will get a 3.5-liter V6 engine that produces 306 horsepower. The base engine is mated to a six-speed sequential shift automatic transmission with paddle shifters. Drivers can choose from four driving modes: Normal, ECO, Sport S and Sport S+. The Sport S+ mode is only available on certain models. All-wheel drive will be optional.

“Interior changes include a new instrument panel with a wide-screen video display, and more headroom, shoulder room and legroom for back-seat passengers,” Autoweek reports.

Lexus says it will also launch 2013 GS hybrid and F Sport models in early 2012. No pricing for any of the new 2013 GS models has been announced yet. The 2011 GS 350 starts at $46,900, while the all-wheel drive version is $48,850. Rear-wheel drive 2011 GS 460 models have an MSRP of $55,370.
