Its all about definitions. Still have been making machines that use an engine to generate electricity to work the machine. A Hybrid should use both power sources to power the machine separately at the most economical times and together for maximum output.
I don't think there is a place in the market for Hybrid forklifts, the only reason Hybrid cars have a place in the market is because of the tax breaks governments have put in place to encourage so called greener motor vehicles. I can't see there being any such incentives for lift trucks seeing as there is already a proven range of electric powered machines for most applications.
Hey but who am i to argue with Toyota.
