# This Jeep Wrangler Has Six Wheels and a Steam Engine

We’ve seen some crazy things in terms of engine swaps. We’ve seen a [turbocharged Nissan Silvia engine in a Mustang II](<https://www.thedrive.com/article/15114/this-ford-mustang-ii-mach-1-has-a-turbo-nissan-silvia-engine>), a [Viper V-10 in a BMW M3](<https://www.thedrive.com/watch-this/14740/this-bmw-m3-e46-is-packing-a-viper-v-10>), a [blasphemous Mustang with a Corvette powertrain](<https://www.thedrive.com/article/14947/this-1967-mustang-with-a-corvette-powertrain-sits-on-a-throne-of-lies>), and even a [Hellcat-powered Prius](<https://www.thedrive.com/news/15688/this-1000-hp-hellcat-powered-toyota-prius-is-political-incorrectness-incarnate>). Just when we thought we’ve seen it all, somebody went and put a [steam engine](<https://www.thedrive.com/article/6406/a-steam-powered-fire-truck-nearly-killed-jay-leno>) in a 2008 [Jeep Wrangler Unlimited](<https://www.thedrive.com/news/13248/check-out-this-custom-jeep-wrangler-built-to-conquer-africas-terrain>). Oh, and also added two more wheels.

It’s called the Loco Hauk built by Hauk Designs in Chambersburg, Pennsylvania. The “loco” part serves two meanings as it both has a steam engine like a locomotive and it is absolutely crazy. According to Four Wheeler Network, the engine is a 100ci V-4 single-acting, trunk-piston, poppet-valve uniflow steam engine and the transmission is a NSG370 6-speed manual. Three water pumps feed water to the boiler in the steam engine from a 55-gallon water tank at a pressure of up to 1,000 pounds per square inch. This is achieved thanks to six batteries and six constant duty solenoids keeping everything running. A full 55-gallon tank of water can move the Loco Hauk 1 to 1.5 miles at 30 to 35 mph.

Loco Hauk has BDS four-link suspension with four-inch BDS coil springs and Fox shocks. This beast sits on six Grid Off-Road GD1 wheels with 41.5x13.50R17 Pit Bull Rocker tires. Being a 6x6 vehicle to make it more like a locomotive, this Jeep has three differentials. The front and rear diffs are TeraFlex D60 units and the middle axle is a Ford nine-inch.

This Jeep has a wild west vibe inside and out. Old school gold accents on the black paint hit home the train aesthetic and that continues in the interior. It has a 19th-century locomotive steam gauge with vintage water well pumps for the steam control and shifters. Some nice modern conveniences include diamond stitch leather seats from Star Fabrication and a Kicker stereo.

A steam engine in a JK Wrangler isn’t most practical or most powerful engine swap we’ve ever seen, but it’s certainly one of the most interesting.
