GM’s signature ISV pedestrian vehicle combat mode

GM Defense Vehicle (ISV) wins $214.3 million US Army contract

Among the many intriguing things about the Chevy Colorado ZR2-based GM Defense Vehicle (ISV) is a feature called Combat Mode, a technology designed to give soldiers the best chance of getting out of a difficult and deadly situation with the goal of taking them out and saving their lives. .

Essentially, combat mode keeps the car running when other security systems try to turn it off.

“At ISV, we kept a lot of the systems alive from the [Colorado ZR2] production model, like whether it heated up and what you might think of ,” Mark Dickens, chief architect of GM Defense Vehicles said of that defense vehicle. In a limp home situation and things like that,”

Dickens describes the situation: “But suppose you’re in a fight and you take a bullet, and the chariot is trying to save itself but you need to get out of the harm’s way. You have the ability to turn on combat mode, and it goes beyond all that. in the same time frame,

Combat Mode We give this infantry defense vehicle a boost of 25 hp, which allows the soldier to get out of there at exhilarating speed, knowing that this is not the maximum power, as the total output of the 2.8-liter Duramax Turbo Diesel LWN I -4 is up to 300 Horsepower with 425 lb-ft of torque. “

It seems counterintuitive at first that a powertrain that may be so close to failure is suddenly expected to handle more power than ever before. In a normal civilian situation, and if this happened during a military operation, it would be a disaster.

It would almost certainly lead to a huge problem for stranded soldiers and expensive repairs. Basically what we’re interested in is Telesoldiers, and a defensive infantry car can be a lifesaver, even if the powertrain is only left for a few more minutes. Each combat mode mission is to remove the wounded soldier from the battle automatically through what is known as the home and dispatch modes.

Dickens explained: “Service is where the battle takes place and a lot of things happen. The home situation can be described as a limp mode, and the combat mode technology goes beyond all of that to just one end of getting out of danger, whatever the technical problems.

Up to 70 percent of GM’s ISV infantry defense vehicle is based on the Chevy Colorado ZR2. In fact, Dickens previously explained that the ISV is essentially a “waist-down” Colorado ZR2.

ISV Dynamic Multiple Suspension Spool Valve Dampers (DSSV) use precision spool valve technology to predict maximizeability, accuracy and repeatability, reduce vibrations for occupants and provide the ultimate in wheel and vehicle control.

Lower skid plates protect the front suspension, engine, transfer case, fuel tank, rear differential and rear shock mount. Advanced software and calibration ensure optimum performance for the engine, transmission, transfer case, front and rear differential lock and electronic power steering.

The remaining 30 percent includes an open cockpit design with a polished steel chrome exterior, seating for up to nine passengers, a C127 digital live gauge cluster, Chevrolet off-road racing components, and special tuning of the MultiMatic dynamic suspension valve. . (DSSV) with dampers.

After recent field tests at Fort Bragg, North Carolina, the US Army selected a GM Defense Infantry Division vehicle for further evaluation, contracting to build and test two more prototypes beginning in fall 2019.

The price for each vehicle was not disclosed, but the US Army awarded GM a contract worth $214.3 million to target the Army’s initial purchases of 649 units plus needed support. Overall, the Army has a target of accquiring 2,065 vehicles for the Infantry Brigade Combat Team.

“This is a fully integrated platform that leverages GM’s decades of engineering, manufacturing, and quality expertise at scale to deliver the most cost-effective, reliable, and effective answer possible to meeting and exceeding the Army’s demanding requirements,” said GM’s President of Defense Infantry Vehicle (ISV). . David Albritton added. “We are very proud of the opportunity to move forward with this competition and to continue our development of a vehicle that will enable Army units to move around the battlefield with greater ease and reliability.”
