I can think of nothing BETTER for a hybrid than towing. The amount of oomph needed to get rolling or up hills (comparatively short periods) is WAY more than the what's needed for normal steady-state hauling. A hybrid system means being able to scale the engine for how it operates MOST of the time plus a bit for charging up rather than peak loads that it only needs to put out for a minute or two at a time.That's a huge step. Good fro them. It gets a little more challenging when you consider vehicles like the Suburban and Silverado, who need more muscle for towing. Come summer, my Suburban becomes a "tow-mobile."
