U.S. Tuner’s 800 HP Hummer H1 Is The Most Unlikely Track Toy Ever

If you want a track car that flies under the radar, get a cheap Lotus. If you want a track car that turns even more heads than a Ferrari, get a Hummer. Wait, what?

Yes, the famed Hummer H1 can be turned into a track car and this build proves it. While an affordable Lotus would probably be faster around a tight circuit, it’s hard to envisage many track toys that scream for attention quite like this.

The Hummer in question was originally built way back in 1987 and has since had its 6.6-liter LBZ Duramax engine reworked by Mil-Spec to deliver 800 hp and 1500 lb-ft (2033 Nm) of torque. These figures are what you’d expect to see from a European exotic, not a 31-year-old Hummer.

To handle the power and transmit it to the ground, the vehicle features a Stage 5 Allison 1000 transmission. What’s more, the entire suspension geometry was altered to allow for track use, including a 7-inch lowering kit that drops the Hummer to the floor. Other track-focused alterations made to the vehicle include 6-piston Wilwood calipers with vented and slotted rotors. Pirelli P Zero rubber ensures the Hummer doesn’t spin up its tires at even the slightest touch of the throttle.

To complete the build, Mil-Spec fitted an ARB air locking differential, roll bar, Sparco racing seats, Momo race-spec steering wheel, and a powertrain kill switch.

The tuner could have overhauled the vehicle’s body to make it a little more aerodynamic but decided not to, retaining the H1’s boxy looks.

      The real question is why not?

      Because you can, that’s why! Because blowing the doors off a tuned Honda or otherwise high performance car, in a military truck no doubt, is why you came into existence in the first place is why! 🙂

    6.6 LBZ Duramax in 1987 great Scott’s. Bet that a bugger to stuff into DeLorean and get to 88 mph for time travel it more than likely came with 6.2 non turbo and refitted with 6.5 both made by Detroit diesel. They are inherentley stiff and that 7″ lowering is going to make it even stiffer along with mini wall tires. That transmission is not road course material the th400 that came in it could be made ready more easily and a g force 5 spd is adaptable. The next thing these guys need to do is turn a HEMMT into a rallye car with a Ford powerstroke and a Spicer 10×10.

  • “The Hummer in question was originally built way back in 1987”

    But the civilian version of Hummer was originally unveiled in 1992… so they are using an actual former military HMMWV? Then how you register them on the road? Since the surplus is literally sold with an agreement not to make the car road legal.

      Good Question! This specific truck is called the “track titan”. It was developed for use solely on the track. Mil-Spec Automotive utilizes civilian Hummer H1’s on all production trucks. Thanks!
