Dodge takes the title for most extreme machine with the Tomahawk, a Viper-engined motorcycle, on which Chrysler group chief operating officer Wolfgang Bernhardt roared onto the show stand. The 8.3-liter, 500-hp, V-10 mates to a 2-speed gearbox and a double chain drive. The billet metal machine has dual front and rear wheels, each independently sprung and braked. Front and rear lamps are located in between the wheels. The rider lays atop the bike, with his feet stretched out behind. Chrysler claims the Tomahawk would accelerate from 0 to 60 mph in 2.5 seconds, with a top speed in excess of 300 mph, although they have yet to find someone to try it. The wildest part? They might build it.
