The GM Bison was a gas turbine freight hauler displayed at the 1964 World’s Fair in New York.

It was designed with grand plans, aerodynamic and fuel efficiency not the least among them.

Part of GM’s Futurama exhibit, the prototype’s cab had seating for two ahead of the engine and wheels. Drivers would have entered the sleekly-sloped cab through a forward-tilting canopy and a step that folded down as the canopy opened. Truckers would have steered using two coupled hand grips on a console extending over the driver’s lap.

The futuristic-looking truck never made it to market, although its power source, the GT-309 with two turbines of 280-hp and 720-hp, powered GM’s TurboCruisers II and III, Rapid Transit Experimental (RTX) and the 1969 GMC Astro 95 Turbine. The gas turbines in the ’70s and early ’80s used far too much fuel but were powerful, gave out low emissions and ran on almost any form of petroleum..

The Bison had a trailer locking device and a four-option steering arrangement that made exceptional maneuverability in urban traffic and freight terminals.
