LS600h L
While this Lexus sports a big and important-looking grille, almost all the air which goes into the engine compartment for cooling, and into the top end of the engine itself to combine with gasoline for the detonation (explosion) which drives the pistons up and down to spin the crank at the bottom-end of the block, caused by the spark plugs (that's today's quick lesson in "How a Car Works"), actually comes from under the front-end of the car. Note the large shark-snout-like openings under the grille in the photo. Those are the real air inlets. That reality is a major reason the first head-to-head competitor with the original Lexus LS sedans, the Q model from Infiniti, had no discernible grillework on its front end. Eventually, to try and increase sales of those very wonderful Q-machines, Infiniti stylists gave-in to requests from the company's showrooms, where salespeople were hearing from potential customers that they liked the traditional grillework on the Lexus. And they were also being asked, "Where's the grille on this car?" But today's modern vehicles which actually have air coming into the engine bay from three feet above the ground are very few and far between.
