You read the title right, we're talking about the Mercury Beaver XR-7. No, Mercury never officially built a car called the beaver. This is the brainchild of upstate New Yorker Chip Beam, who owns and operates Beaver Energy, LLC. It runs on gases created by wood pellets fermented in a 2,400-degree furnace and fed to a supercharged Ford 4.6-liter V8.
By all accounts, it gets down the road just fine, and has pretty close to full power. The best part is, you can grow the fuel yourself and avoid patronizing big oil, if that's your thing. The only drawback that we can see to the Mercury Beaver XR-7 is the PVC pipe jungle occupying the space that would be the trunk under normal circumstances.
Still, if you're willing to smell like a mountain man and look like a bad Back to the Future knockoff, this ride is right up your alley. Click past the jump to see Translogic's take on this modified Merc.
