On the face of it, the Audi Q7 and Mitsubishi Outlander have few things in common. They're both (mostly) seven seat SUVs and that's pretty much where they part company. Except if you have a poke around the spec sheets of both ranges, you'll find something quite interesting.

Both are offered as five seat plug-in hybrids because the batteries take up the space of the third row.

But, once again, here is where they depart because the cheapest PHEV (Plug-In Hybrid Electric Vehicle) starts at an absurdly reasonable (for a PHEV) $45,990.
