This Hummer is ready to take on all-comers for track supremacy.
You wouldn’t normally think of a military HMMWV--or “Hummer”, as the Army used to call them--as a performance vehicle. They had plenty of torque, sure, but that was so they could haul artillery pieces and full squads of infantry through the desert. They were never designed to go fast.
This one, though--this one can go fast thanks to quite a few customizations performed by the Hummer experts over at Mil-Spec.
But before we get to the nitty-gritty of what makes this a very fast utility vehicle, a bit of backstory. This was originally a 1987 AM General HMMWV, a born and bred military truck. When it was born, it came with a 6.2-L diesel V8 engine with a top speed of around 70 mph. It had mounts for machine guns, gun ports for the soldiers inside, and armor for the underfloor to prevent IEDs from killing the occupants.
Then Mil-Spec got a hold of it and decided to use it as a testbed for the modifications they planned to perform on the civilian Hummers that they could buy used. What started as a simple engine swap turned into a "what if" moment, as in "what if we made a Hummer into a track monster?"
To that end, the original Diesel has been replaced by a larger 6.6-L Duramax turbo-diesel V8 operating at 40 lbs of boost and outputting 800 hp and 1,500 lb-ft of torque. All that power goes through an Alison 6-speed automatic transmission to either the rear or all four wheels.
Zero to sixty is done in as little as 6.5 seconds, which is pretty fast for a utility vehicle that weighs close to 6,000 lbs.
We don’t get to see Seen Through Glass take it around an actual track, but we do get to see the Hummer put its foot down on the pavement in an impromptu street race. This Hummer can really haul.
