Truck enthusiasts are on the edge of their seats in anticipation of the all-new 2014 Chevrolet Silverado and GMC Sierra, which are expected to be major game-changers in the fullsize segment, but that doesn't mean General Motors is just coasting until then. There are a few updates in store for 2013 models.

We also included updates on other models in the Chevrolet and GMC truck and SUV lineup, some of which we've previously covered as part of our coverage of the 2012 Chicago Auto Show.


Chevrolet Silverado: 1500 models get powertrain grade braking, which helps slow the vehicle using the engine, in normal mode on models with six-speed automatics (instead of tow/haul mode). Deep Ruby Metallic and Blue Topaz Metallic are added as new color choices for both 1500 and HD models. The big news on the HD side, however, is the availability of the Duramax 6.6-liter V-8 diesel in a full-power 397-hp version for the 3500 HD Chassis Cab and box-delete models, which were previously de-tuned to 335 hp. Like the other domestic truck brands, Chevrolet is jumping on the natural-gas bandwagon with its 2500 HD bi-fuel model.

GMC Sierra: Changes for GMC's fullsize truck line largely mirror those for the Silverado, with Sonoma Red Metallic and Heritage Blue Metallic being the new colors for GMC. As with the Silveardo, both 1500 and HD models receive powertrain grade braking. Changes in power for the chassis cab and box delete models weren't specifically mentioned for the Sierra, but GMC is also getting a bi-fuel version of its 2500 HD truck for 2013.

Chevrolet Captiva: Although not technically new, this is the first year Chevrolet has specifically called out its fleet-only compact SUV as part of model-year updates. If the Captiva looks familiar, that's because it's essentially a mildly restyled Saturn Vue equipped with new drivetrains. The Captiva was quietly announced last year as a fleet-only model and is available with a 3.0-liter direct-injected V-6 shared with the Equinox, or the 2.4-liter direct-injected I-4 that serves as the base engine in the Equinox and Terrain. For 2013, the V-6 option is dropped, leaving the four-cylinder as the sole motivator.


Chevrolet Equinox: The big news for the Equinox for 2013 is the addition of the 301-hp 3.6-liter V-6 first shown in the GMC Terrain Denali as the optional vehicle. The new mill, gives the small SUV a substantial power bump of 37 hp and 50 lb-ft of torque over last year's 3.0 V-6. Changes to the Equinox aren't limited to what's under the hood, however. Chevrolet's MyLink infotainment system joins the lineup offering stereo audio streaming, Bluetooth hands-free calling and smartphone control, and Pandora and Stitcher streaming audio, newly available with navigation. 2012 models forced the choice of MyLink or navigation. Other changes include a new rear-seat entertainment system with wireless headphones and monitors built in to the headrests, an eight-way power passenger seat, and universal home remote.

GMC Terrain: The Terrain also gets the 3.6-liter engine as well as the addition of the upscale Denali trim level, which includes 19-inch wheels on the V-6 model, eight-way power passenger seat, and blind-zone and rear cross-traffic alert. GMC's version of MyTouch, called IntelliLink, is also available with navigation for 2013. A safety package with forward collision alert, lane departure warning, and rear park assist is new for 2013. Atlantis Blue Metallic, Champagne Silver Metallic, Ashen Grey Metallic and Iridium Metallic are new color choices.

Chevrolet Tahoe/Suburban: Aside from the addition of powertrain grade braking, there are no changes confirmed for Chevrolet's full-size SUV duo.

GMC Yukon/Yukon XL: Minimal changes for GMC's jumbo SUV line. Champagne Silver Metallic is a new color option, and like the Sierra and Silverado, powertrain grade braking is added in normal transmission mode.

Chevrolet Traverse: Unveiled at this year's Chicago Auto Show, the 2013 Chevrolet Traverse gets an extensive facelift along with its Lambda cousin, the GMC Acadia. In addition to the all-new front end, the Traverse gets an upgraded interior with more soft-touch surfaces, blue ambient lighting, and 6.5-inch center color touch radio with available MyLink. The other big enhancement for 2013 is the addition of a front-center airbag designed to prevent the driver and front passenger from colliding with each other in the event of a side-impact collision.

GMC Acadia: In a reflection of its "professional grade" heritage and market positioning, the 2013 GMC Acadia gets a much more prominent grille and butchier front end, helping it fit in better with the rest of the GMC lineup. The Acadia Denali gets a standard power tilt and telescoping steering wheel and an eight-way power front passenger seat (also offered on SLT models) plus the front-center airbag like the Traverse. All models get available IntelliLink with nagivation, side blind zone and rear cross traffic alert, standard rear-vision camera, revised transmission tuning, and dual-flow shocks for an improved ride and handling. Champagne Silver Metallic, Iridium Metallic and Atlantis Blue Metallic are added to the list of color choices.
