The U.S. Secret Service is preparing to refresh its fleet, turning to General Motors Defense for a new generation of rugged vehicles. The aim is to replace the agency’s blacked-out Chevrolet Suburbans, which, while effective in the U.S., often stand out too much overseas.

Speaking to Car and Driver, Secret Service director Sean Curran explained that the agency works closely with GM Defense to tailor vehicles to the terrain, threat level, and mission profile. He noted that in regions like Africa, a more discreet vehicle would be better suited than a massive SUV.

Although specifics remain classified, potential candidates include GM Defense’s Infantry Squad Vehicle (ISV), derived from the Chevrolet Colorado ZR2, and the Light Utility Vehicle (LUV), built on the Silverado HD platform for the Canadian Armed Forces.

EVs like the GMC Hummer EV-based eMCV are unlikely to make the cut, as their limited range and reliance on charging infrastructure make them impractical for remote missions. There’s also speculation that GM could develop an entirely new platform tailored to Secret Service needs, though such a move would be expensive and time-consuming.

In essence, the agency appears to be shifting toward vehicles that combine military-grade durability with a lower profile abroad—a strategic evolution for one of America’s most visible security institutions.
