The Chrysler eBeam is a fully electric rear-axle drive module produced from 2023 onward. It features a single permanent-magnet synchronous motor integrated into a compact e-axle assembly. This system delivers 215 kW (288 PS) and 549 Nm of instant torque, enabling rapid acceleration and quiet operation.
Fitted exclusively to the Ram 1500 REV, the eBeam system was engineered for robust towing capability and smooth, responsive power delivery characteristic of electric vehicles. Emissions compliance is inherent (zero tailpipe emissions), meeting all current global standards including US EPA Tier 3 and Euro 7 equivalent requirements for BEVs.
One documented engineering update addressed a software calibration affecting regenerative braking smoothness under specific low-temperature conditions. This issue, referenced in Stellantis Technical Service Bulletin EV‑01‑24, was resolved via an over-the-air (OTA) software update deployed in Q2 2024, refining the brake blending algorithm.
All production years meet zero tailpipe emissions standards (US EPA Certification #AID2023eBEAM, EU Type Approval e24*2023/XX).
The Chrysler eBeam is an integrated electric drive system engineered for full-size pickup trucks (2023-Present). It combines a single permanent-magnet motor with a single-speed reduction gear to deliver instant, linear torque and robust towing performance. Designed for zero tailpipe emissions, it prioritizes efficiency and capability within a heavy-duty platform.

The single-motor design provides robust, instant torque ideal for towing and hauling but requires using the specified Mopar® eGear 75W-85 oil for the eAxle gearbox to ensure longevity. The system is sensitive to extreme cold, which can temporarily reduce regenerative braking effectiveness and range. The OTA software update (Q2 2024) resolved initial brake blending smoothness issues per Stellantis TSB EV-01-24. Battery preconditioning before DC fast charging is recommended for optimal charging speed.
Oil Specs: Requires Mopar® eGear 75W-85 specification for eAxle (Stellantis Service Manual 09-13-21).
Emissions: Certified as Zero Tailpipe Emissions (EPA #AID2023eBEAM, EU e24*2023/XX).
Power Ratings: Measured under SAE J2908 standards (Stellantis Engineering Spec. #ENG-eBEAM-HP).

The Chrysler eBeam system is used in Stellantis's DT platform with rear-wheel drive configuration. This system received a significant software update in 2024, creating a distinction between pre-update and post-update vehicle behaviors. All adaptations are documented in OEM technical bulletins.
The eBeam system is identified by the vehicle's model designation (Ram 1500 REV) and VIN. The 8th digit of the VIN is 'E' for electric powertrain. Visually, it can be identified by the absence of an exhaust system and the presence of high-voltage orange cables running to the rear axle. The eAxle itself has "eBeam" casting marks. Critical differentiation from dual-motor systems: The Ram 1500 REV uses a single eBeam unit on the rear axle; a front eAxle is optional for 4x4 models but is a separate component. Software version can be checked via the vehicle's infotainment system under 'Software Updates' (Stellantis Service Manual 09-13-21).
The eBeam's primary reliability consideration is software-related behavior, with the initial regenerative braking calibration being the most documented concern. Stellantis service data indicates this was effectively resolved via the Q2 2024 OTA update. Secondary considerations include managing expectations for range under heavy load or extreme temperatures. Adherence to recommended maintenance, particularly eAxle fluid changes, is critical for long-term hardware reliability.
Analysis derived from Stellantis technical bulletins (2023-Present) and early NHTSA owner complaint data (2023-2024). Repair procedures should follow manufacturer guidelines.
