Here's what Chris Doane has to say about the pictures:
Chevy has been very busy testing their new Silverado this week, with a fleet 6-8 prototypes doing numerous test runs. We thought we'd seen most of the prototypes, but then a new one began testing yesterday that caught our eye.
This particular Silverado looks quite a bit sportier than the rest, with large, chrome wheels, and a stance that may suggest this truck was made for speed. Chevy engineers also seem to be guarding this single cab/short box prototype a little closer than the rest.
While the towing mirrors seem an odd choice for a possible "Sport" truck, these may be in place purely for testing purposes. Even with performance vehicles, OEMs will often tow trailers with ballast to put additional stress on the powertrain. This Silverado test group has been spotted using box trailers for that very reason.
We've asked a number of industry sources today about the existence of a Silverado Sport model, and the consensus seems to be "maybe." When asked if "street trucks" were a thing of the past, one competitive intelligence analyst told us rather cryptically, "Don't be so sure."
While we can't say for sure if this is a Silverado Sport, this truck does seem to have a "go fast" look to it. Chevy certainly has a history of making sportier versions of their trucks, and offering an alternative to Ford's Harley Davidson F150 could appeal to GM as well.
In addition to the possible sport model, and the Silverado Extended Cab we shot on Monday, we've also managed to snag some photos of a Silverado 1500 Crew Cab.
Codenamed "K2XC," production of the regular, 2014 Silverado is currently slated to begin in April 2013. The heavy-duty models, codenamed "K2XCZ," will follow in October of 2013. Both will be built at the Flint, MI and Ft. Wayne assembly plants.
So what do you guys think? Does GM have an SS up their sleeve?
