Edison's Series-Hybrid Pickup: 75-Mile Electric Towing Range for the Modern Fleet

Edison has demonstrated a significant shift in heavy-duty utility vehicles by proving their diesel-electric pickup can tow an 8,000-pound Airstream for 75 miles on a single charge. This performance relies on a 60 kWh battery pack that powers the electric motors directly, while a modest diesel generator serves only as a range extender rather than the primary power source. By decoupling propulsion from the internal combustion engine, the vehicle maintains high efficiency during static and low-speed maneuvers, a critical factor for commercial operators who frequently idle or move short distances. This architecture allows the truck to operate silently and emission-free during the initial 75-mile segment, addressing the immediate pain points of urban and suburban towing logistics.

For fleet managers and individual owners, this technology offers a tangible reduction in operational costs and environmental impact. The system leverages regenerative braking to recapture energy, further optimizing the battery's utility. Once the battery depletes, the small diesel generator kicks in to maintain consistent power output, ensuring the vehicle does not suffer from the range anxiety typical of pure electric models. Compared to conventional diesel pickups, this series-hybrid approach delivers up to 30% in fuel savings while significantly lowering tailpipe emissions. This balance of electric agility and generator-backed endurance makes the vehicle a viable alternative for daily drivers who require heavy towing capability without compromising on fuel economy or regulatory compliance.

Key Findings

• Towing Capability: Successfully tows an 8,000-lb trailer for 75 miles on a 60 kWh battery.
• Hybrid Architecture: Uses a series-hybrid design where the diesel engine acts solely as a generator.
• Efficiency Gains: Achieves up to 30% fuel savings compared to standard diesel counterparts.
• Emission Reduction: Operates with zero tailpipe emissions during the initial electric range.
• Regenerative System: Incorporates braking energy recovery to extend usable battery life.
