Here are two prototypes of the upcoming Silverado HD dually refresh undergoing testing. One (towing via a hitch) appears to be a lower-end model while the other (towing via a gooseneck) is a High Country trim.
The Silverado is expected to gain a refresh that will bring an updated exterior design, a new cabin with 13.4-in. infotainment screen and new powertrain bits with more power and torque. It is obvious from these photos that GM is placing an emphasis on the updated truck’s towing capacity, which has recently taken third place in max trailering ratings when compared to Ford and Ram.
Sources have confirmed that 6.6L Duramax V8 will make at least 500 hp and 1,000 lb.-ft. of torque, which is a substantial upgrade compared to the current specs of 445 hp and 910 lb.-ft. of torque.
Expect an official debut this fall.
