The enticing roar of the Cayenne V8 from your own vehicle, is sure to stick out and get attention. So on seven stretches of asphalt, billboards introduced drivers to the Cayenne Kilometer. The Billboards were equipped with our own powerful roadside antennas transmitting the sound of the Cayenne straight into everyone's car, literally taking over drivers’ radios. Every Cayenne Kilometer ended right by an exit towards a local dealer, where a real Porsche was waiting for those who couldn’t resist the call of the Cayenne.
