Future products: GMC looks beyond trucks to compact car

GMC, traditionally a home for rebadged Chevrolet trucks with more content, is preparing to jolt its lineup with a compact car aimed at young urban buyers.

General Motors Co. is expected to bring the GMC Granite to market in 2013. The Granite concept's front passenger seat pivots up and toward the console. With the seat up, a bicycle can be transported without removing its front tire.

GM gave the concept the turbocharged, 1.4-liter four-cylinder engine that's an upgrade on the Chevrolet Cruze.

Here are GMC's plans for the 2011-13 model years.

Terrain: The five-seat crossover may get a high-end Denali version in the 2012 model year. A freshening will come in the 2013 model year. The Terrain may receive a hybrid version around the 2014 model year.

Acadia: This crossover gets a freshening in the 2012 model year, along with a 3.0-liter V6 engine instead of its current 3.6-liter version.

Yukon, Yukon XL: GM has decided to introduce a next-generation, truck-based Yukon SUV, rather than put the vehicle on its Lambda crossover platform. The next generation will appear in the 2014 model year, likely sharing some sheet metal with the Sierra pickup to cut costs.

Around that time, GM may upgrade the Yukon's two-mode hybrid--whose planetary gears and two electric motors save fuel--to a four-mode version, which would improve efficiency in a wider range of driving and towing situations.

Canyon: GM will idle its plant in Shreveport, La., by June 2012, discontinuing the Canyon. A decision to reintroduce a compact pickup isn't expected for at least a couple of years after that.

GM will sell a next-generation global Chevrolet Colorado--the Canyon's current sibling--outside the United States, and that vehicle could come here. But GM is leaning toward an even smaller design.

Sierra 1500: A compressed natural gas version probably will appear in 2012, and the pickup will be re-engineered and restyled for the 2014 model year.

Sierra 2500, 3500: GM re-engineered its heavy-duty pickups for the 2011 model year. A restyle is expected in the 2014 or 2015 model year. These pickups also will get compressed natural gas versions in about two years.

Savana: The van gets compressed natural gas capability in the 2011 model year.
