In this part of his 2012 Pebble Beach Concours tour, Jay Leno takes us to the Concept Lawn, where he takes an up-close look at some of the finest concepts at this year’s event. He takes a particular interest in the fully electric infiniti Emerg-E, and the Mercedes Concept Style Coupe, which is a stylish mid-size four-door coupe. Jay also pops by Rolls Royce corner to check out their new bespoke car.
