Michigan-based off-road monster specialist Mil-Spec Automotive has unveiled what it calls its most ambitious build to date. The Mil-Spec M1-R is a heavily modified Hummer H1 with a $412,000 price tag.

The M1-R kicks off a new M1 series of Hummer builds that Mil-Spec calls its second generation, after the Launch Edition model that first appeared in 2018. The upgrades start in the engine bay, where Mil-Spec installed a balanced-and-blueprinted Duramax LBZ 6.6-liter diesel V-8, which drives all four wheels through an Allison 1000 T6 automatic transmission.

The General Motors-sourced diesel engine produces 500 hp and 1,000 lb-ft of torque in the standard M1, according to Mil-Spec’s website, but the M1-R boasts 800 hp and 1,200 lb-ft of torque. To handle that power, Mil-Spec gave the M1-R Wilwood brakes with 6-piston calipers, an air-locking differential, and Rod Hall long-travel racing suspension.

As if a stock Hummer H1 didn’t attract enough attention, Mil-Spec sprayed the M1-R in custom yellow paint inspired by the factory H1 Competition Yellow, but with a bit of metalflake thrown in. Based on the H1 soft-top body style, the truck also gets a large spare-tire carrier that takes up most of the bed, and elaborate front armor.

Mil-Spec said it eliminated all plastic from the interior. The switchgear is metal, while nearly everything else is covered in nappa leather in a shade that matches the exterior. A pushbutton gear selector replaces the stock shift lever.

While the M1-R was a one-off commissioned build, Mil-Spec is taking orders for the standard M1, which has a (slightly) less shocking $299,500 price (including the cost of a donor vehicle).

Michigan-based Mil-Spec Automotive started out with elaborate Hummer H1 builds before expanding to the Ford F-150. The company announced Tuesday that it is adding a supercharger upgrade for the pickup truck’s 5.0-liter V-8.

The Mil-Spec Automotive Intrepid F-150 boasts 675 horsepower, up from the 500 hp available from Mil-Spec’s previous upgrade package. The supercharger upgrade, which is also good for 620 pound-feet of torque, is bundled with a new throttle body, intake, fuel rails and injectors, and cat-back exhaust system. Mil-Spec also adds an air-to-liquid intercooler and moves the intake to a lower position.

Note that Mil-Spec tunes the V-8 for 93-octane fuel, while the stock version can run on regular unleaded, according to Ford. The engine modifications don’t affect the truck’s warranty, Mil-Spec claims.

The supercharged Intrepid F-150 gets the same aggressive look as other Mil-Spec trucks. The company’s Baja fenders are seven inches wider than the fenders of a 2020 Ford F-150 Raptor. Other modifications include Baja bumpers, LED lighting, a roof rack, and a bed chase rack that holds a spare tire.

The truck also gets Mil-Spec’s Baja Performance Suspension package, with Fox Racing shocks and new control arms and half shafts. It allows up to 12 inches of overall travel, according to the company.

The interior sports a custom steering wheel, magnesium paddle shifters, and leather upholstery.

Mil-Spec hasn’t released pricing for the Intrepid F-150, but its naturally-aspirated F-150 builds start at $85,000, including the cost of a donor vehicle. Mil-Spec is only modifying outgoing-generation F-150s for now, but perhaps the company will make the jump to the heavily revised 2021 model as well.
