Dodge Tomahawk

[Merlin]

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. The Tomahawk concept is an awesome-sounding machine. 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 and less shrill.


The Dodge Tomahawk can reach 60 miles an hour in about 2.5 seconds, and has a theoretical top speed of nearly 400 mph. Each pair of wheels is separated by a few inches and each wheel has an independent suspension. Bernhard said four wheels were necessary to handle the power from the engine.

Ca a au-moins 3 ans ce concept de dodge.

[prodsac]

ca date de 2003. Ca verra jamais le jour. Dodge allait bien financierement dans ce temps. Maintenant, a moins que je me trompe, dodge existe pratiquement meme plus?

Y'a Chrysler, Jeep et RAM..

Exercice de style plutôt qu'un test de marché. Le chassis était machiné dans un bloc d'alu. Pratiquement pas utilisable. Sur Youtube, on voit des vidéos à basse vitesse et en ligne droite. Ça ne virait pratiquement pas. De plus, avec ces 4 roues, la législation américaine et canadienne le considérait comme une voiture avec toutes les exigences que cela implique. Pour des motos avec des moteurs de Pick-up, il y a la Boss Hoss avec le moteur chevy de 6L. Cette moto est plus qu'un exercice de style, elle est commercialisée. http://www.bosshoss.com/view_bike.asp?x=BHC3ZZ4

Chez Dodge :

Grand Caravan qui vends vraiment beaucoup, Charger de police donc blé assuré, challenger pour les ginos et en plus de ça les RAM qui vendent en fou.

De plus la Van volkswagen est une Grand-Caravan maquillée donc encore plus de ventes.

Franchement, je les vois pas au bord du gouffre :P
