But there are more subtle, and functional, cues. The tailpipes, for example, are melded right into the body work at the rear of the car in a way a regular vehicle's tailpipes wouldn't be. These tailpipes never get hot, since the only thing that passes through them is cool water vapor.
Up front, the Equinox's extra-large grill opening and the big vents under the headlights are there because, even though the exhaust is cool, the fuel cell does create heat. In a regular car, the tailpipe carries away about a third of that excess heat.
Since the Equinox's exhaust doesn't take away any heat, the fuel cell vehicle requires extra cooling area up front.
