Still, as stylish and luxurious as new trucks are becoming, functionality has to remain the category's core value. "GMC raises these elements to new heights in the Terra4 - a four-wheel drive, four-wheel steer truck with four doors and four ways to access the cargo area," Zipfel continued.
While optimizing cargo and people hauling capabilities has to drive any future product plans the Terra4 presents some unconventional ideas to get the job done. A completely integrated design incorporates a closed body with a short, deep rear box, maximizing usable space. The cabin sports a cab-up-and-forward design that opens up interior space for passengers as well as luggage behind the rear row of seats.
Doors on the rear quarter panels make accessing the cargo area a breeze while a more conventional rear tailgate is still provided. GM's designers have added a retractable decklid cover consisting of aluminum slats, similar in execution to a roller blind. The feature allows security for smaller items when closed and space for taller, bulkier cargo when open.
Increasing load carrying flexibility the Terra4 uses a rear wall pass-through similar in execution to the Chevy Avalanche that, once the rear seats are folded even with the cargo bed allows longer items to load in easily.
