Michigan-based off-road monster specialist Mil-Spec Automotive has unveiled what it calls its most formidable construct up to now. The Mil-Spec M1-R is a closely modified Hummer H1 with a $412,000 price ticket.

The M1-R kicks off a brand new M1 collection of Hummer builds that Mil-Spec calls its second technology, after the Launch Edition mannequin that first appeared in 2018. The upgrades begin within the engine bay, the place Mil-Spec put in a balanced-and-blueprinted Duramax LBZ 6.6-liter diesel V-8, which drives all 4 wheels by means of an Allison 1000 T6 computerized transmission.

The Basic Motors-sourced diesel engine produces 500 hp and 1,000 lb-ft of torque in the usual M1, in line with Mil-Spec’s web site, however the M1-R boasts 800 hp and 1,200 lb-ft of torque. To deal with that energy, Mil-Spec gave the M1-R Wilwood brakes with 6-piston calipers, an air-locking differential, and Rod Corridor long-travel racing suspension.

As if a inventory Hummer H1 did not entice sufficient consideration, Mil-Spec sprayed the M1-R in customized yellow paint impressed by the manufacturing unit H1 Competitors Yellow, however with a little bit of metalflake thrown in. Based mostly on the H1 soft-top physique model, the truck additionally will get a big spare-tire service that takes up many of the mattress, and elaborate entrance armor.

Mil-Spec mentioned it eradicated all plastic from the inside. The switchgear is steel, whereas practically every little thing else is roofed in nappa leather-based in a shade that matches the outside. A pushbutton gear selector replaces the inventory shift lever.

Whereas the M1-R was a one-off commissioned construct, Mil-Spec is taking orders for the usual M1, which has a (barely) much less surprising $299,500 value (together with the price of a donor car).
