Future Product Guide: GMC Vehicles For 2012, 2013, 2014 Model Years | GM Authority
"Canyon: even though GM has (finally) confirmed that the next-generation Chevy Colorado will make its way to the States, it has not announced any plans for a GMC version. As such it’s unclear whether the new truck will don both the Chevy Colorado and GMC Canyon nameplates, but we think that GMC will get a version of the truck in 2013. For the sanity of truck fans all over North America, we hope that the Chevy and GMC midsizers will be differentiated by more than a simple badge engineering job. Engines in the international-market Colorado include the 2.5 and 2.8 liter Duramax turbo diesels making as much as 346 lb.-ft. of torque (in the 2.8 model). Furthermore, new CAFE requirements will most likely result in the discontinuation of the range of outdated powertrains in current model, including the large yet not very power-dense fours, fives, and eights."
Diggin the new GMC Granite...
"Granite Debut: having been greelit for production, the subcompact crossover will bow in 2012 for the 2013 model year. The Delta II-based model will share its platform with the Cruze and Verano, although it will ride on a shortened wheelbase. Staying true to the concept, it will also have Dutch doors and have a pickup variant that was shown as the Granite CPU. The concept was powered by a 1.4 liter turbocharged Ecotec engine mated to a six-speed manual transmission — the same powertrain as in the Chevy Cruze. The production version may get the 2.0 liter turbocharged Ecotec or GM’s new 2.5 liter naturally aspirated Ecotec."
