Chevrolet is bringing CNG power to the Silverado HD

Chevrolet is taking CNG-powered vehicles seriously, with so many of their trucks being used in commercial fleets, so it was perhaps no surprise that we'd see a version of the 2015 Silverado HD that can be run either on gasoline or compressed natural gas before long. Chevrolet brought the 2015 Silverado 2500 HD CNG to the Chicago Auto Show, to let prospective buyers as well as the media to learn about at the savings that could be realized with this environmentally friendly setup. The HD CNG truck will offer bi-fuel capability coupled with its 6.0-liter V8 engine that's been modified with hardened valves and valve seats to run on compressed natural gas.

GM sees no potential buyers for Saab

General Motors has found no interested buyers for Saab, sources familiar with efforts to sell the Swedish brand say. GM put Saab under "strategic review" as part of the long-term viability plan submitted to Congress last month. In a subsequent interview with Automotive News, GM Vice Chairman Bob Lutz said strategic review is "code for we realize they're not working and something needs to be done." GM has not announced a decision to sell the brand, but has quietly shopped it around, the source said.
