The 2554 AMG Transport Dynamics M12S "Warthog" Custom Sports Truck is a fictitious civilian transport variation of the AMG Transport Dynamics M12 "Warthog" FAV featured in the Halo franchise, and was made available to drive in Forza Horizon 3.
|“||The 2554 AMG Transport Dynamics M12S Warthog CST is a civilian transport alternative to its militaristic cousin, the M12 Force Application Vehicle. What it may lack in brute force – you won’t find a turret on this version – it more than makes up for with its 720 bhp twin turbo V8, making it significantly faster than its FAV counterpart. The Warthog CST in Forza Horizon 3 is also ideally suited for the rough and tumble landscape of Australia. With the most advanced suspension in Forza Horizon 3 (with more than 70 cm of suspension travel), plus advanced dampening, you won’t find the combination of power and stability like this anywhere else in the Horizon Festival.||”|

The Custom Sports Truck is a twenty-five percent smaller rendition of the Force Application Vehicle utilized by the United Nations Space Command, fitted with a smaller displacement 8 liter V8 instead of the military's 12 liter hydrogen-injected internal combustion engine, and a lighter curb weight, makes it more approachable for civilian usage.
Its V8 produces 720 hp (537 kW) at 6,500 rpm and 855 ft·lb (1159 N·m) of torque at 3,200 rpm. The high power output of the engine, combined with an all-wheel drive system and short 6-speed gearbox, allow the M12S CST to reach a top speed of 119 mph (192 km/h) in just over 10 seconds.

- The "Looks More Like A Puma" challenge is a reference to episode 2 of the Halo fan series Red vs. Blue, and consists of the Red team arguing over which animal their new M12 LRV closely resembles.
