The Dodge Tomahawk is a non–street legal concept vehicle introduced by Dodge at the 2003 North American International Auto Show that was subsequently produced and sold in very small numbers. The Tomahawk attracted significant press and industry attention for its striking design, its outsize-displacement, 10-cylinder car engine, and its four close-coupled wheels, which give it a motorcycle-like appearance. Experts disagreed on whether it is a true motorcycle. The Retro-Art Deco design's central visual element is the 500-horsepower (370 kW), 8.3-litre (510 cu in) V10 SRT10 engine from the Dodge Viper sports car. The Tomahawk's two front and two rear wheels are sprung independently, which would allow it to lean into corners and countersteer like a motorcycle.
