Rather than tackle the Raptor on common ground, word has it that Chevrolet is preparing a different kind of performance off-road truck. A lighter one, based on the forthcoming midsize Colorado. Details are scarce (and could prove entirely speculative), but the self-styled experts at GM Authority report that a hardcore Colorado is in the works, potentially taking its lead from the Colorado Rally Concept and picking up some customers lost by the demise of the Hummer H3T but reviving the ZR2 trim plate.
GM Authority goes on to speculate that the lighter package could allow GM to use a smaller, potentially turbocharged V6 engine instead of the big V8 in the Raptor while still giving it an optimal power-to-weight ratio. After all, the Raptor may pack over 400 horsepower, but it also weighs over 6,000 pounds.
Of course, as we haven't seen any mules or prototypes of such a vehicle running around or heard word of it out of GM formally or otherwise, we're going to take this rumor with a whole shaker full of salt, and we advise you do the same.
