Allison Transmission, a leading designer and manufacturer of conventional and electrified vehicle propulsion solutions for tactical wheeled and tracked defense vehicles, is pleased to announce Allison’s 4000 Specialty Series™ transmissions are included in the U.S. Army’s Common Tactical Truck (CTT) prototype vehicle phase.

The U.S. Army has proposed replacing most variants in its heavy tactical wheeled vehicle fleet with a single platform that shares a common powertrain, chassis and cab. The Army selected four companies to each provide several different prototype vehicles to refine specifications as the program moves to vehicle testing in 2024 and initial production by 2027.

Allison’s proven propulsion solutions are operating in nearly all the Department of Defense’s medium and heavy-duty tactical trucks. The company continues to invest in fuel efficient technology such as Allison FuelSense^® 2.0, an advanced set of software and electronic controls that deliver fuel savings of up to 6% and reduce CO₂ emissions in conventional vehicles all while ensuring maximum equipment readiness of the Army’s tactical wheeled vehicle fleet.

In addition, Allison Specialty Series transmissions are equipped with the company’s next generation electronic controls platform, which delivers advanced communications, functional safety, cybersecurity and over-the-air programming that are at the forefront of commercial vehicle industry adoption.
