A look at GMC future products

In coming months, GMC will be working to reignite sales growth for its popular crossovers. After that, its focus will be on the next generation of its highest-volume vehicle: the Sierra pickup.

The Acadia full-sized crossover will be restyled with extensive interior upgrades when it goes on sale in late fall. GMC also will look to wring out more volume from its No. 2 seller, the Terrain crossover, when a high-end Denali version is launched this fall.

The next-generation Sierra 1500 pickup is due by late spring 2013, followed by a new Yukon SUV to arrive in the second half of 2013.

GMC dealers will continue to wait for a model that is not also badged as a Chevrolet. GM decided to scrap plans to make the Granite subcompact crossover, which it showed at the 2010 Detroit auto show.

Here are highlights of GMC's 2013-15 model years.

Terrain: The crossover gets an optional 3.6-liter V6 that generates 301 hp for the 2013 model year vs. a 3.0-liter V6 that produces 264 hp that is offered in the 2012 Terrain. The IntelliLink infotainment system will be optional. GMC also is adding a high-end Denali model.

For the 2014 model year, expect the addition of GM's eAssist mild hybrid system. The Terrain likely will be redesigned for the 2015 model year.

Acadia: The large crossover has been restyled for the 2013 model year to include wraparound rear glass, new LED running lamps and an improved transmission. Interior improvements add more soft-touch materials and IntelliLink. The Acadia is due to be redesigned for the 2015 model year.

Yukon, Yukon XL: The next-generation large SUVs are expected to go on sale in the second half of 2013 as 2014 models. They will use the fifth generation of GM's small block V8, which will have direct injection, variable-valve timing and cylinder deactivation, likely mated to an eight-speed transmission.

Canyon: The 2012 model year will be the last for the current version of the mid-sized pickup.

While GM has confirmed plans for a next-generation Chevrolet Colorado, the Canyon's twin, the automaker has been mum on plans for the GMC brand. Sources say to expect one to come for the 2014 model year with a GMC badge and significant styling variation from the Colorado. The engine lineup is likely to include a 3.6-liter V6 and a 2.0-liter turbo. A Duramax diesel engine is sold in Asia and could be offered here.

Sierra 1500: The redesigned Sierra is expected in showrooms by late spring as a 2014 model. The full-sized pickup is expected to drop several hundred pounds from the current version through greater use of aluminum and high-strength steel.

It will get GM's next-generation small-block V8 engine, which will feature direct injection, variable-valve timing and cylinder deactivation. An eight-speed transmission is likely.

Sierra 2500, 3500: Restyled versions of GMC's heavy-duty pickups, which were re-engineered for the 2011 model year, are expected by late 2014 as 2015 models.
