Plug-in hybrid SUVs are becoming increasingly popular, thanks no doubt to their fuel-efficient powertrains. This technology allows these vehicles to help make up for one of the biggest drawbacks of typical sport-utility vehicles: their lower gas mileage.
Now, not all plug-in SUVs are exactly economical, but they can provide two major advantages over non-hybrids. First off, you can drive plug-in models for a practical distance using electricity alone. The second benefit comes if you do run out of electricity. At that point, the powertrain switches over to traditional gas-hybrid operation for hundreds of more miles of range — with higher mpg levels than their non-hybrid rivals, and none of the “range anxiety” you get from a purely electric vehicle.
