Spy Shots—2014 Silverado HD Chassis Cab Source: SEMA The shooters at KGP Photography grabbed their latest look at a massive prototype for Chevrolet's next-generation Silverado HD Crew Cab Chassis Cab. The new Chassis Cab, and the rest of upcoming revamped HD lineup, will incorporate the changes recently unveiled on the standard-duty Silverados, according to KGP. Additional focus has reportedly been put toward fuel economy while also searching for more power to compete with the the latest heavy-duty offerings from Ford and Ram. Although the Silverado 1500 has now gone official, HD prototypes continue to have their interiors thoroughly covered. That would seem to point to some interior changes for the HD versions, but the shooters have been unable to get photo confirmation.
