The biggest problem today's
The biggest problem today's wimpy hybrids have in high mountains is that they don't have enough battery to really help them. The batteries get depleted after a few hundred feet of climb and then the ICE (Internal Combustion Engine) has to rev very hard and still may have trouble maintaining speed. On the downslope, the batteries fill up pretty fast and then they simply freewheel like any pure ICE car.
They're still more efficient than an ICE car with comparable flat-land performance though since they have a smaller, hence more efficient, ICE.
I have yet to find an application where a hybrid is less efficient than a pure ICE car with comparable performance.
Does anyone own a 2011 or
Does anyone own a 2011 or 2012 Lincoln MKZ Hybrid? If so, I am eager to hear your comments as I'm seriously interested in purchasing one of these cars.
