While this brute might look like a golf kart for the Expendables crew, the Bowler CSP RIV is actually a bona fide military concept vehicle. The British company built it for the 2017 Defence and Security Equipment International Show, and the CSP RIV marks the first in a series of rugged 4x4s Bowler will build for military and emergency services. Known as a Rapid Invasion Vehicle, the CSP is built from lightweight aluminum alloy and coupled with a full internal roll cage for maximum rigidity. Power comes from a 300-hp V6 with a whopping 516 lb-ft of twist. It’s mated to an 8-speed transmission with a hydraulic converter and planetary gearsets. The CSP RIV can transport four occupants, and it has a 4,409-lb payload capacity. Sadly, this one up for auction doesn’t come with the .50 cal heavy machine gun that was on display when the CSP was shown. It’s also not street legal but would make for one bitchin’ ATV.
