The Cougar's power is supplied by a single Caterpillar C-7 diesel engine developing up to 330 horsepower and mated to an Allison 3500SP transmission. Suspension is full 4x4 or 6x6 depending on the chassis model with a vehicle ground clearance of 15 inches. Armor protection remains classified as of this writing. The 4x4 vehicle weighs in at roughly 43,000lbs and can seat up to 6 personnel including 2 as standard operators (drivers). The 6x6 version weighs in at a maximum of 64,500lbs and can seat 2 standard operators along with 8 additional passengers. Range of the Cougar is listed at 420 miles with a top speed of 55 miles per hour.
Fording is possible up to 39 inches at a 40 degree approach angle. A top-mounted hatch is standard as are heating, air conditioning and automatic engine and crew cabin fire extinguisher systems. Tires are Michelin XZL 395/85 R20 types. Additional methods of entry are provided for through the driver and co-driver sides as well as a rear-mounted crew double door.
Both Cougar models can fit remotely-operated turret systems with armament of the operators choosing. Armament can include a Browning M2 12.7mm heavy machine gun, an M240 7.62mm general purpose machine gun, an M249 SAW 5.56mm light machine gun or the Mk 19 40mm automatic grenade launcher. Armament can also be supplemented by any crew-served weapons fired through the available firing ports.
The British Army took delivery of similar systems beginning with the Ridgeback PPV (Protected Patrol Vehicle). These systems were based on 4x4 Cougars built by FPI with British-friendly armor and electronics systems which included the "Enforcer" remote weapon station. The Mastiff PPV (Protected Patrol Vehicle) is the Cougar 6x6 system built by FPI, again with British-friendly systems and armor. With this version, however, conversion is being handled by NP Aerospace.
Production of MRAP class vehicles began in 2002 at a single unit cost of $475,000 ($644,000 per unit of the 6x6 version). Operators of the system include the United States, United Kingdom (157 Ridgebacks and 248 Mastiffs), Iraq (1,050 to be delivered), Italy (operating at least 6 Cougar 6x6 models), Hungary (at least 3 examples) and Poland (operating at least 40 Cougars on loan from the US military).
In addition to the US military use, the Cougar was also utilized by Blackwater USA during their tumultuous tenure in Iraq.
The Cougar is certified for military air transport.
