Lexus GS takes its turn on the 'Ring

The Lexus LF-Gh Concept from this year's New York Auto Show is slowly making the journey from pure conceptual creation to full-on production car, albeit, in the form of the GS sedan. Our trusty spy photographers have caught a Lexus GS prototype out on the Nürburgring, and its LF-Gh-inspired cues are clearly in evidence despite heavy camouflage.

Up front, the LF-Gh's squared-off headlights have translated over to this GS test mule, complete with LED daytime running lamps. Even the "aggressive and bold spindle-shaped front grille" from the concept looks to be intact, as are the upward curving detail lines that form the outline of the lower side air intakes in the front fascia.

Mum's the word on what's under the hood, but we'd be shocked if it wasn't some sort of hybridized powertrain, perhaps similar to what's already found in the GS 450h. The production car likely won't debut until the end of 2011 or early 2012, so we'll keep our ears to the ground for more information until then.
