GM plans half its cars on ethanol by 2012: report
The report quoted GM North America President Troy Clarke at the Chicago Auto Show as saying GM will have 11 ethanol-capable vehicles on the market this year and 15 in 2009.
Earlier, start-up biofuel company Coskata Inc, part owned by GM, said it has formed a strategic alliance with ICM Inc to build a commercial plant to mass produce cellulose-based ethanol. The plant is due to open in late 2010.
