The Tomahawk concept is an awesome-sounding machine; we saw it started and revved. Clouds of blue smoke vied for attention with the throaty rumble of the mighty V-10, and hitting the gas visibly opened the twin throttle body blades up front where the headlight would normally be. Though deeper and more rumbling than most motorcycles, it did not seem to be louder overall - just deeper, with no shrill overtones.The Tomahawk is a Viper V-10 based motorcycle, a 500 horsepower engine with four wheels beneath it. The engine breathes through twin throttle bodies mounted right up front.At the time of its introduction, many did not believe the Tomahawk could be ridden and leaned into a turn. The Italian company Piaggio has since demonstrated with their very well received MP3 scooter, that, given adequate development time, the same basic principal could in fact be successfully implemented. The Tomahawk however was conceived and built to serve only as a communication tool, having as its mission to promote the Dodge brand, while showcasing the Viper motor as well as the creativity of the people behind that brand. The entire project, from conception to finished show vehicle was limited to only five months. The show vehicle therefore did not benefit from the sort of extensive dynamic development phase typical of production vehicles.
