By Steven J. Ewing, Autoblog - According to a report from GMInsideNews.com, General Motors has shut down its hybrid program for company's next-generation of full-size pickup trucks and sport-utility vehicles. Currently, the Chevrolet Silverado, Tahoe, GMC Sierra, Yukon and Cadillac Escalade all use the two-mode hybrid technology.Historically, the two-mode hybrid models have not sold well, and only yield minor improvements in overall fuel economy. In most applications, the two-mode hybrid system is rated at 11.7L/100km (20 mpg) in the city and 10.2L/100km (23 mpg) highway.
GMI reports that it's unusual for programs like this to be shut down so close to the launch of a new vehicle -- the next-generation trucks/SUVs are scheduled to debut for the 2014 model year -- but that many sources within GM are not surprised about the move. These new full-size hybrids were reportedly supposed to use an updated two-mode system, featuring a smaller displacement V8 engine, upgraded battery storage (using a more modern lithium-ion pack) and revamped electric motors, according to GMI.
When contacted by Autoblog, a GM spokesperson only stated that the automaker could "not comment on future products or related technologies."
