2014 GMC Sierra [w/video]

Big And Boxy Might Be Best
As immense fans of the Back to the Future trilogy, we sometimes like to envision an alternate timeline in which General Motors had killed off GMC and kept Pontiac instead. The G8 GXP would still be on the road handily beating German sport sedans costing twice as much, while the lowly G3 would morph into a true subcompact-killer based on what is now the Chevrolet Sonic RS. While we're at it, let's go ahead and imagine the G6 has become the best-selling car in the US and the Torrent crossover is selling 20,000+ units per month. Far-fetched, we know.
The thing is, these fanciful statements would have to be true to make the case against keeping GMC. Pontiac may have offered more excitement than GMC, but money talks, and a full line of trucks, crossovers and SUVs have made a lot more money for GM than the arrowhead brand ever did. How much? As we learned last month, about two-thirds of GM's global profits came from its fullsize trucks, and GMC's trucks typically have thicker margins than their Chevrolet counterparts.

GM recalling Silverado and Sierra HD diesel pickups over fuel gauge follies

General Motors is recalling 9,733 of its heavy-duty twins over concerns with their 6.6-liter diesel engines and dual fuel tanks. The recall covers some Chevrolet Silverado HD and GMC Sierra HD pickups from model years 2012 and 2013, although the exact dates that the recalled trucks were built isn't specified. There's also no mention of how many models come from Chevrolet and how many are from GMC.
The problem rests with the transfer pump responsible for moving fuel from the rear tank to the front tank - it could fail, resulting in an inaccurate fuel gauge. It hardly requires explaining, but a faulty fuel gauge could leave drivers in a situation where they run out of diesel.
GM will begin notifying customers of affected vehicles, who will be asked to report to their dealers for a free replacement transfer pump.

Chevy Colorado, GMC Canyon midsize pickup trucks to get diesel engines

The market for midsize pickup trucks has all but been abandoned in the US, but General Motors is about to shake the market up with the all-new (to the US) Chevrolet Colorado and GMC Canyon. Launching next year, GM already told us that its new trucks would be a "fuel-efficient alternative" to fullsize trucks, and aside from the smaller size, Automotive News says that these trucks will accomplish this with a diesel engine.
According to the AN report, the next-gen Colorado and Canyon will offer a small, four-cylinder Duramax turbo diesel with a displacement of either 2.5 or 2.8 liters - both engines are currently used in this truck for other markets. This would allow GM to join the Cummins-powered Nissan Titan and Ram 1500 EcoDiesel as the only non-HD trucks in the US to offer diesel. The article goes on to say that the diesel versions of the Colorado and Canyon would launch about a year after the trucks go into production in fall of 2014.
