Fat Girl
Owned by Leo Kuether, of Grand Forks, North Dakota, this intoxicating mixture of rolled radius 17/8-inch DOM tubing and brute American muscle personifies the concept that functionality does not have to look boring. With swoopy lines, contoured body panels, and an unmistakable rumble at idle, "Fat Girl" has an appearance of going fast, even when she is standing still.

With negative approach and departure angles, front and rear steering and power to spare, this buggy is poised for battle. A compact chassis keeps this buggy from encountering snags, and removable body panels make accessing the underlying componetry a simple five-minute affair. A durable silver powder-coat keeps the rig's tubework from rusting while also improving visual appeal.

  • Most looking forward to: "Tank Trap. I love the unexpected."
  • Not looking forward to: "Tank Trap. It seems to be the most unexpected."
  • Playing in his iPod/CD player: "Nothing. I have SiriusXM! Jason Ellis Show rocks! Red Dragons!!"
  • Kuether says: "I'm crazy and not medicated."

The engine bay is packed tightly, with only the bare necessities in view. Tubing protects all essential componetry from rollover damage, and the chassis design features bolt-together flanges in key areas to allow easy serviceability. The Ram Jet 502 puts out an estimated 560 lb-ft of torque at 5,000rpm. A massive aluminum radiator manages coolant temperature, while exhaust is routed through a set of Sanderson headers.
