Green Monster 6

The six-wheeled Green Monster Number 6 became the first dragster to break 150 miles per hour (241 km/h) in the quarter mile.

Built in Akron Ohio by Walter and Art Arfons and driven by the later, this car was named by Speed Age Magazine in 1957 as "Number One on any list of theWorld's Ten Fastest Hot Rods"
First to achieve 150 mph in a quarter mile from a standing start, it was slow off the mark in order to prevent burning the tyres so most of the speed wasactually attained in about an eighth of a mile and the engine was never opened to more than half throttle on any run.

It is 20 feet long, weighs two tons and has a ground clearance of just two inches. The 1,450 horsepower V-12 Allison aircraft engine drives both front and dual rear wheels. It has no transmission but used a 50-ton Army tank clutch. 14 gallons of water circulates through the engine and chassis frame tubes for cooling without a radiator.

This Green Monster was succeeded by a series of jet-powered creations, In one of these Art Arfons set the world land speed record three times on the Utah Salt Flats and crashed on the fourth attempt on November 17, 1966 at a speed of 600 mph. The vehicle was demolished but Art was uninjured
