Electric vehicles offer several advantages over their traditional combustion-engine counterparts. They have lower operational and maintenance costs, produce less noise and heat, and can provide high torque at low speeds — ideal attributes for covert operations and rugged terrains. Moreover, the adoption of EVs aligns with the global push towards sustainability, a principle that has permeated every sector, including defense.

At the heart of this trend is GM Defense, a company that’s marrying its rich automotive heritage with cutting-edge technology to create next-generation military vehicles. A standout product from their stable is the electric version of the Infantry Squad Vehicle (ISV).

Shaping the future of military vehicles: GM’s electric ISV

The electric ISV, developed by GM Defense, is a shining example of how electric vehicle technology can be adapted for military use. This innovative vehicle is built on a flexible platform that allows it to meet a variety of mission requirements, all while delivering the benefits of electric power.

Designed to support ground forces, the ISV is mechanically related to the Chevrolet Colorado pickup, using around 90 percent off-the-shelf components. Its electric powertrain provides a single motor that puts out 200 horsepower and 361 Nm (266 lb-ft) of torque. Even with its relatively small 60 kWh on-board battery pack, the electric ISV can achieve a range as high as 150 miles (240 km) or as low as 70 miles (110 km), depending on terrain and driving conditions.

However, the capabilities of the electric ISV extend beyond just its specs. As GM Defense spokesperson, Sonia Taylor, noted, the ISV performed exceptionally well off-road, demonstrating what’s possible with electric technology in a short amount of time. This includes navigating a steep, muddy, and rocky hill climb, a testament to the vehicle’s robustness and adaptability.

The potential and limitations of battery technology

Electric vehicles’ viability in military applications hinges primarily on the progress of battery technology. Advancements in this field have been rapid, but there are still significant hurdles to overcome before EVs can fully replace diesel-powered military vehicles.

The primary challenge lies in balancing energy density, weight, and range. While EVs can offer high torque and almost silent operation, these advantages are offset by the weight of the necessary battery packs and the limited range they provide. The large variation in range based on driving conditions can also pose a reliability issue in critical military operations.

The path to overcoming battery technology challenges

While the limitations of current battery technology present significant challenges, both GM Defense and other industry players are hard at work to overcome these hurdles. This involves continuous research and development to boost energy density, reduce weight, and extend the range of batteries for EVs.

GM Defense has already demonstrated its commitment to this cause by creating the All Electric Concept Vehicle, a one-off ISV that could hint at the future of light military vehicles. This initiative is a testament to GM Defense’s dedication to exploring the boundaries of what is possible with electric vehicles in military applications.

Furthermore, GM’s strategic collaboration with Element 25 for local manganese sulfate production marks a significant step in securing supply chains for electric vehicle production, signaling GM’s commitment to a cleaner energy future. In addition, GM’s collaboration with Tesla, a leader in the EV industry, promises to usher in improvements in charging times and battery efficiency. Such partnerships could potentially expedite the arrival of EVs on the battlefield and beyond.

As this research and collaboration continues to progress, it is likely that the limitations currently facing EVs in military applications will be steadily reduced, paving the way for an electrified future in defense operations.

Implications for defense strategy

The move towards electric power isn’t just about environmental sustainability or technological advancement; it also has profound implications for defense strategy. The unique attributes of electric vehicles, such as near-silent operation and the elimination of a heat signature, could fundamentally change the way military operations are conducted.

The All Electric Concept Vehicle developed by GM Defense, for instance, has already demonstrated these potential benefits. During a test at the Charlotte Motor Speedway Rock City Campground, the vehicle showcased its off-road capabilities, completing the same course as the standard ISV, including a steep, muddy, and rocky hill climb.

Transition to electric power also introduces new challenges for defense strategy. For instance, the reliance on electricity for vehicle operation introduces a new vulnerability: the need for a reliable and secure power supply. This could potentially impact the strategic planning of military operations, with considerations for power supply infrastructure and battery charging times becoming critical factors.

Environmental implications

As the world grapples with the urgent need to curb carbon emissions, the shift to electric vehicles in the military could have a profound impact on environmental sustainability. The use of electric power in place of fossil fuels could significantly reduce the carbon footprint of military operations, contributing to global efforts to combat climate change.

Already, the automotive industry has been making strides in this direction.
