Indianapolis, United States — September 12, 2025:
Allison Transmission has officially announced that its groundbreaking Neutral at Stop fuel-saving technology will now come standard on Kenworth and Peterbilt models equipped with the Allison 4700 Rugged Duty Series™ (RDS) transmissions. The integration of this technology aims to improve fuel efficiency and significantly reduce operating costs for commercial fleets, particularly in stop-and-go duty cycles, such as urban delivery and refuse collection.
Neutral at Stop works by automatically shifting the vehicle’s transmission to neutral when the vehicle is stopped but still in gear—such as at stoplights or in heavy traffic. As the driver begins to accelerate, the system quickly shifts back into gear, allowing for smooth vehicle movement. This process minimizes engine load, resulting in reduced fuel consumption and lower overall operating expenses for fleet operators.
Rohan Barua, Vice President of North America Sales, Global Channel, and Aftermarket at Allison Transmission, commented, "We are proud to offer the Neutral at Stop feature as standard on Kenworth and Peterbilt trucks with our 4700 RDS transmissions. This technology provides our shared customers with a fuel-efficient solution that enhances vehicle performance while reducing costs."
The Neutral at Stop feature is part of Allison's broader FuelSense® 2.0 package, a collection of technologies that can collectively achieve up to 6% fuel savings. This reduction in fuel consumption not only helps fleet operators save money but also contributes to a more sustainable and environmentally friendly operation, aligning with global efforts to reduce carbon footprints.
The introduction of this technology on Kenworth and Peterbilt trucks marks a significant step forward in the evolution of fuel-saving innovations for commercial vehicles, promising benefits across a range of industries reliant on heavy-duty transportation.
