The '''Dodge Tomahawk''' is a concept vehicle produced by [[Dodge]].
At the 2003 [[North American International Auto Show]] in [[Detroit, Michigan]], Dodge unveiled a vehicle with an unusual design, featuring the 500 hp (373 kW) 8.3 L V10 [[engine]] from the [[Dodge Viper]]. The vehicle has two front wheels and two rear wheels, making it a kind of motorized [[quadricycle]] rather than a typical [[motorcycle]].
__TOC__
==Sales==
In [[2005]], Dodge decided to sell 10 versions at [[United States dollar|US$]]550,000 each through [[Neiman Marcus]]. While the Tomahawk is not [[Street-legal vehicle|street-legal]], it could, theoretically, be ridden. The Tomahawk, as sold, is missing a few trivial parts necessary to make it a running bike. Dodge has done some minimal testing on the first bike built, and then-COO [[Wolfgang Bernhardt]] drove it onto the stage at the [[Detroit Auto Show]]. The Tomahawk is officially sold as a "rolling sculpture" to show the Viper engine.

* Sequential, multi-port electronic fuel injection with individual runners
* Compression Ratio: 9.6:1
* Max Engine Speed: 6000 rpm

* Cooling System: Twin aluminum radiators mounted atop engine intake manifolds, force-fed from front-mounted, belt-driven turbine fan. Takes 11 quarts (10 L) of antifreeze.
* Exhaust System: Equal-length tubular stainless steel headers with dual collectors and central rear
* According to the official specs 0-60 [[mph]] times have been estimated at 1.75 [[second]]s, with an estimated top speed of 750 mph. But there are also reports that the top speed is 676 km/h (about 420 mph). It is very unlikely that anyone will ever test the vehicle, due to safety concerns and the price of the Tomahawk itself. Dodge has expressed interest in one day taking it to the Bonneville salt flats, but as of yet has not.
This is for people who are passionate about engines," said Chrysler Chief Operating Officer Wolfgang Bernhard, who rode the Tomahawk on stage during a media preview. "A motorcycle is the most beautiful way to showcase an engine."
The 1,500-pound Tomahawk can reach 60 miles an hour in about .75 seconds, and has a theoretical top speed of 420 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.
Chrysler executives said if the Tomahawk were put into production, it would draw attention to the Dodge brand in ways no ordinary sports car could. Bernhard said a decision on whether to build the Tomahawk could be made in several months.
The Tomahawk is a Viper V-10 based motorcycle, a 500 horsepower engine with four wheels beneath it. Ten hand-built reproductions, each to be sold at a price of $555,000.
