Called “Loco Hauk” This 2008 Jeep Wrangler Unlimited was built by Hauk Designs. The crazy project took eight weeks to build for their show Road Hauks on the History Channel.
The Loco Hauk weights 5.5 tonnes and its powered by a 100 CID V-4 single-acting, trunk-piston, poppet-valve uniflow steam engine that produces 130-140 horsepower. It has a NSG370 6-speed manual transmission.
The engine is fed from a 20 gallon boiler and a 55 gallon water tank. The 16 gallon factory fuel tank was converted to hold the kerosene to heat the boiler. The drivetrain consists of a factory NSG370 6-speed manual transmission and NP241 transfer case.
The front axle is a Teraflex D60 with Auburn Gear Max Lock locker and 3.73 gears, the middle axle is a Ford 9″ pass-through with 3.70 gears, and the rear axle is Teraflex D60 with Auburn Gear Lock locker and 3.73 gears.
