Allison Transmission has announced advancements in its hybrid-electric propulsion systems for commercial fleets, focusing on improved fuel efficiency and reduced emissions. 

1. eGen?Flex® Max (CertPlus variants): builds on the base eGen Flex by offering full electric-only propulsion capability for extended segments, ideal for zero-emission zones without external charging infrastructure 
2. eGen?Power® 130D high-capacity e-Axle: variant of the 100D tailored for 13-ton GAWR vehicles, maintaining identical power/torque specs but with reinforced mechanical packaging for heavier commercial and bus applications 
3. eGen?Force™ hybrid propulsion system for defense vehicles: designed for tracked combat vehicles up to 75?tons, with 220?kW electrical output, torque blending and multi-gear range pack, enabling silent electric mobility and fuel-efficient hybrid boost 
4. Continuous Power Technology™ consultation services: optimizes axle ratios using Allison’s iSCAAN software, reducing fuel use ~2–3?% in refuse and heavy-duty fleets through shallower gearing with uninterrupted torque during shifts 
5. Vehicle Electrification + Environmental Test Center access: offers fleet operators the ability to validate hybrid propulsion system performance under simulated extreme environments—accelerating EV integration while reducing testing capital 
6. Allison Ventures strategic partnership investments: support development of next-gen hybrid/electric components and startups aligned with fuel-agnostic propulsion platforms, ensuring future-proof integration across fuel sources 
7. Expanded Authorized Service Network support for hybrid systems: now offers 1,600+ certified locations globally, including expanded North America and overseas hybrid system training, parts and diagnostics for eGen Flex and Power systems
