The 2007 Saturn Vue Greenline SUV helps build a case for plug-in hybrid vehicles. The hybrids were upgraded with AFS Trinity Power Corp.ís Extreme Hybrid technology. AFS Trinity teamed with Ricardo Inc. to integrate the Extreme Hybrid system, which uses two ultracapacitors and lithium-ion batteries, as well as a transmission Ricardo created for the test vehicles. In road tests, the XH-150 achieved an all-electric range of 41.9 miles. When operating on batteries alone, its 0 to 60 mph time is 11.6 sec. In full hybrid mode, that shrinks to just 6.9 sec.
