AFS Trinity took a 2007 Saturn Vue Green Line SUV and turned it into the XH-150, a 150 mpg gas sipper extreme plug-in hybrid vehicle (PHEV). Using a hybrid system that utilizes both lithium-ion batteries and ultra capacitors, they not only turned on the fuel economy, but they also improved the power. The SUV can now go 0-60 in 6.9 seconds when in full hybrid mode. That's better than the Lexus RX400h.
Pretty cool stuff...
