NEW YORK This eye-catching Nissan Altima ad from Omnicom’s TBWA\Chiat\Day in Playa del Rey, Calif., smartly touts the new coupe as a sexy must-have accessory. In this execution, the agency skips standard car-ad fare (so long, Mr. Highway!), focusing instead on speed and performance to deliver a simple message, “True style.” Firehouse red-on-black images of the car take the shape of various coveted products—a cell phone, a running shoe—and the results are striking. In this case, it’s a snazzy watch. The car headlights add some sparkle. And even though every inch of the watch is made of the same car, the attention to detail adds another layer of engagement that holds the eye.
