Precisely two weeks remain for the official presentation of the all-new 2013 Lexus GS 350 on Thursday, August 18th at the Pebble Beach Concours d’Elegance, and the Japanese automaker decided it's time to enter the teaser photo game with the release of a single, partially blacked out image of the mid-size luxury sedan.

There's not much to say about the Lexus sedan from the photo other than that it looks a lot like the LF-Gh Hybrid concept we saw at this year's New York Auto Show.

For those of you that would like to see a bit more of the new GS than what Lexus has to offer, hit the break to watch the first test drive videos of the car by U.S. magazines Motor Trend and Road & Track.

Being that Toyota wants Lexus to compete against its German rivals not only in North America, but all over the world, along with the U.S. test drive event of the 2013MY GS in California, the Japanese automaker also coordinated a similar happening for European media at a proving ground in Belgium.

The journalists were invited to drive heavily disguised versions of pre-production 2013 Lexus GS models while the company's Chief Engineer, Yoshihiko Kanamori, was in attendance from Japan to gather feedback from the participants.

Following the announcement on the time and place of the premiere of the all-new 2013 Lexus GS 350 –that would be the Pebble Beach Concours d’Elegance on August 18th for those of you that didn’t read our previous story- the Japanese company lifted the embargo on the first test drive of the car in the States.

Invitees include names like Car&Driver, Autoweek and Motor Trend. Naturally, the exterior of the pre-production test cars were bagged in plastic, but their interiors were largely free of camouflage (see links below for photos) revealing an edgier LF-A-esque design with lots of stitched leather on the dashboard and a gigantic 12.3-inch information screen above the center console.

This year’s edition of the Pebble Beach Concours d’Elegance that takes place in California on August 18 will see Lexus lifting the veil off the next generation of its GS premium sedan, which we recently showed you testing at the Nurburgring racetrack in Germany.

Lexus teased the new GS with the LF-Gh Hybrid concept study at the New York Auto Show in April.

"Our customers have been waiting for a new GS that's more intense in every way," commented Mark Templin, Lexus group vice president and general manager. "They'll soon discover this GS was well worth the wait."

Well now, that didn’t take long, did it? Less than three months after the presentation of the LF-Gh concept car at the 2011 New York International Auto Show and Lexus has already started testing the production model that will spawn a successor to today’s GS sedan at the Nürburgring circuit.

Naturally, the Lexus GS prototype is covered in plenty of camouflage but not to the point that it discloses its styling similarities to the LF-Gh study.

Aside from the body proportions, details like the protruding side sills, the high rising belt line, the “dotted” LEDs and large grille up front, and even the alloy wheel designs, appear remarkably faithful to the concept.

Next up on our motorshow calendar is the 2011 New York Auto Show in late April, where we’re expecting several world premieres, including a new concept car from Lexus. The Japanese automaker made the announcement today through its Twitter channels with a rather vague note: “LF-Gh: LF = Lexus Future. h = hybrid. G = ...”.

The company also stated in an invitation to the press that the concept “will present a glimpse into the future of Lexus design.” We’re assuming the ‘G’ stands for a prototype version of the next generation of the GS premium sedan but we’ll know more within the next couple of weeks.

‘Remember’ is the name of Infiniti’s new campaign for the 2012 M Hybrid, which is set to launch in the USA in spring of 2011 with prices starting from $53,700. The 31 second spot takes us on a quick journey through the history of hybrids, beginning with the first hybrid car in 1888, to the hybrid patent in 1909, and through the hybrids of the 1970s on to today’s hybrid models including the Lexus GS 450h, which can be seen in the ad parked on the road.

According to Infiniti, the 2012 M Hybrid directly challenges “the notion that you can’t have great performance and great fuel economy” adding that its model is the only car in America that delivers 360 horsepower and 32 miles-per-gallon (highway) – combined fuel economy is rated at 29mpg.

There’s no mention in the commercial on the model that single handedly made hybrids a household word bringing the technology to the masses – we’re talking of course about the first generation Toyota Prius.
