Program Context

A university flagship student vehicle prototype program, presented at a major defense ground vehicle symposium.

This series-hybrid rescue platform is a vehicle developed through a university flagship student vehicle prototype program, in partnership with the U.S. Army DEVCOM Ground Vehicle Systems Center and presented at a major defense ground vehicle symposium.

The vehicle is a high-speed, off-road, semi-autonomous search-and-rescue platform built to address real disaster response scenarios, including golden hour medical delivery and unmanned terrain navigation.

EVolve Battery Systems supplied the high-voltage MonoLith battery system, delivering a complete 420V liquid-cooled pack inside the program's aggressive development timeline.

Golden Hour Mission

Vehicle and crew must reach disaster site, map the area, and return with injured within the critical first hour.

All-Terrain Autonomous Navigation

Designed for post-disaster terrain (sand, boulders, urban rubble) using semi-active suspension and autonomous drive.

U.S. Army Research Platform

Sponsored by DEVCOM GVSC as a validation tool for autonomous vehicle dynamics and energy management in off-road environments.
