Introduction
Thor Industries and Harbinger Motors have collaborated to create what they claim to be the world’s first extended-range Class A Motorhome. This innovative RV is set to go on sale next year and utilizes a series hybrid setup that combines an electric motor, a battery pack, and a combustion engine with no mechanical connection to the drivetrain. The system can be powered by both a charge port and a generator connected to the gas engine.
Hybrid Technology
The motorhome features a 1.4-liter gas engine that turns a generator, along with a 140-kWh battery pack that can be charged from a DC or AC charger. The motor was developed by Harbinger Motors and produces 440 horsepower peak and 280 hp continuous, with a torque rating of 1,140 pound-feet. The battery packs can be DC fast-charged in one hour and have a power export feature that allows the RV to act as a generator for powering a whole house during outages. The estimated total range of the vehicle is 500 miles when both the battery and fuel tank are full, with 150 miles achievable on battery power alone, and an additional 350 miles from the gas range-extender.
Chassis and Design
Harbinger Motors provides the frame, suspension, propulsion system, safety, and vehicle systems for the Hybrid Class A Motorhome, while outfitters are responsible for fitting the body and remaining systems. The chassis is estimated to have a service life of 20 years, and the oil-cooled drive unit is designed to last 450,000 miles in commercial truck applications. The RV features a fully independent double-wishbone suspension system at the front and a steer-by-wire system similar to the Tesla Cybertruck.
Advantages of EREV Powertrain
The decision to use an EREV powertrain in an RV offers several advantages over traditional all-electric campers. While all-electric campers have a limited driving range of around 200 miles on a full charge, the addition of a gas range extender allows for longer driving distances. This means that individuals can benefit from lower fuel consumption and still have the ability to run everything inside the RV on batteries without using any fuel for days once they reach their campsite.
Innovative Features
The collaboration between Thor Industries and Harbinger Motors represents an innovative approach to RV design and technology. The Hybrid Class A Motorhome offers a unique combination of power sources, with the convenience of both electric and gas systems. The versatile nature of the motorhome allows for extended travel distances coupled with the ability to operate off-grid at campsites, making it an attractive option for those who enjoy long journeys and outdoor adventures.
Conclusion
Overall, the Hybrid Class A Motorhome by Thor Industries and Harbinger Motors represents a significant advancement in RV technology. This collaboration has resulted in the creation of a vehicle that combines the benefits of electric and gas power sources, offering users a versatile and efficient option for both travel and off-grid living. With a range of 500 miles and the ability to run on battery power alone for extended periods, this motorhome sets a new standard for luxury and sustainability in the recreational vehicle industry.
