Natural Gas engines produce a bit more torque than regular gas engines, plus it's a more green fuel. A lot of farm tractor manufacturers offered Natural Gas versions as a less expensive alternative to their diesel models.

The Wankel isn't known for having very good economy and has always suffered from low torque, which is why it's pretty much never been seen in the 4X4 world.
