Here we have what may quite possibly be the World's Coolest Hybrid. It may not be particularly adept at saving fuel – owner Chris Lentz of Jackson, Michigan, says it burns one to five gallons of kerosene per minute (though presumably it could also run on biodiesel like Jay Leno's EcoJet) but we aren't aware of any other hybrid vehicles that can put out 2700 horsepower at 516 miles per hour.
While half of the 2005 Ford F-150 STX's drivetrain consists of the stock FoMoCo 4.6-liter V8 and four-speed automatic transmission, the truck's coup de grâce is certainly the 1950s-era Czechoslovakian Motorlet M-701 turbojet mounted discreetly in the bed. The 728-pound jet engine is reportedly capable of punching out 1,962 pounds of thrust at 15,500 RPM.
Coupled together, the two engines can push the truck down the quarter mile at 103 miles per hour and up to a measured top speed of 140 mph, though it could likely go faster with a slightly modified mounting arrangement. Speed, though, is only a small part of the story. Click past the break for a video of Lentz's truck in action.
