Stellantis is developing a tri-motor EREV with a gasoline range-extender

Stellantis tri-motor EV tech could change everything

Stellantis has filed a patent for a tri-motor extended-range EV (EREV) system that pairs three electric drive motors with a gasoline-fueled generator to supply electricity and manage torque.

This new tech combines electric power with a traditional gas engine to ensure drivers don’t run out of power. The tri-motor system promises enhanced torque management and better performance, all while increasing the vehicle’s efficiency.

What’s a tri-motor EREV? Let’s break it down

An extended-range EV (EREV) is an electric-first layout in which a fuel-burning engine drives a generator that provides electricity to the traction motors and/or battery; the engine does not directly turn the wheels. Stellantis’ new patent adds a third electric motor, improving torque distribution and power efficiency.

This new setup could revolutionize electric vehicles, offering more power and range. The three motors would work in harmony with the gasoline engine, making the vehicle even more capable. Stellantis is focusing on optimizing these motors to balance performance, battery life, and power.

Could Ram get the most out of this tech?

The next-gen Ram truck could be a perfect fit for Stellantis’ tri-motor setup. With the Ramcharger already using an EREV platform, adding a third motor could push performance to new heights.

Ram currently targets 4.4–4.5 s 0–60 mph for the dual-motor 2025 Ram 1500 Ramcharger; Stellantis has not announced tri-motor truck performance.

That’s the kind of performance a tri-motor setup could deliver. In addition to speed, this setup would likely boost towing power, making it an even more attractive option for people who need a reliable, powerful truck without worrying about frequent charging stops.

Will the Ramcharger get a boost in power?

The Ramcharger, a much-anticipated electric truck, Stellantis has not confirmed a tri-motor Ramcharger; the current model is a dual-motor EREV rated at 663 hp and 615 lb-ft.

It could become a serious competitor for trucks like the Tesla Cybertruck. This upgraded system would not only increase horsepower but also enhance the Ramcharger’s range.

For truck owners who need to haul heavy loads, this tri-motor setup could offer the muscle to match the demands of tough work. As Stellantis refines this tech, the Ramcharger could be the ultimate electric truck, combining long-range performance with the power to tow anything you need.

Chrysler’s flagship sedan could return with a twist

Chrysler might have found the perfect opportunity to revive its iconic Imperial sedan with this tri-motor powertrain. The luxury brand has been missing a flagship vehicle since the Chrysler 300, and this could be their comeback.

A new Imperial equipped with a sophisticated tri-motor setup would offer an unmatched blend of power, luxury, and electric efficiency. As the electric vehicle market grows, Chrysler could carve out a niche with a powerful, sustainable luxury car that stands out in a crowded market.

Heavy duty trucks, a new era of power?

The tri-motor system could also change the future of heavy-duty trucks. Stellantis could replace diesel engines in trucks like the Ram 2500 and 3500, offering electric power without sacrificing performance.

Electric motors could provide more torque than a diesel engine, making these trucks even more powerful. Heavy-duty drivers could enjoy the same pulling power as a diesel truck while benefiting from fewer emissions.

Why three motors mean better performance

A tri-motor electric vehicle promises impressive performance. With three motors working together, the torque distribution is optimized, allowing for quicker acceleration and better handling.

Instead of relying on just two motors to deliver power, this system takes full advantage of three, giving the vehicle more control and stability. This means faster speeds, better traction, and superior handling across a variety of terrains.

How Stellantis plans to optimize torque management

At the heart of this tri-motor system is advanced torque management. Stellantis has filed a patent for a control system that perfectly balances the power output between each motor and the gasoline engine.

This system’s goal is to make sure the vehicle is always running at optimal performance. The control unit ensures that torque is delivered efficiently between the three motors, while the gasoline engine keeps the battery charged.

How the generator extends the vehicle’s range

One of the main advantages of this tri-motor EREV system is the gasoline generator that extends the range of the vehicle.

In an EREV, the generator engages as needed to maintain battery SOC, supplying electricity to the motors and/or battery to extend driving range; it consumes fuel and does not make the vehicle self-charging.

Can this tech solve range anxiety for good?

Range anxiety is a common concern among electric vehicle owners, especially on long trips. With Stellantis’ tri-motor setup, this issue can significantly reduce range anxiety, especially for long trips. By adding a gasoline engine as a backup, Stellantis ensures that drivers never need to worry about running out of power.

The tri-motor system would allow for a more efficient use of energy, and the gas generator would kick in to recharge the battery when needed. This combination gives drivers confidence that they can go the distance without constantly seeking charging stations.

Could this rival the Tesla Cybertruck?

On towing, Ram cites up to 14,000 lb for Ramcharger versus the Cybertruck’s up to 11,000 lb; definitive range/torque comparisons require official, equivalent test figures from both makers.

Tesla’s Cybertruck is known for its rugged design and futuristic features, but Stellantis might be able to match or even surpass it in performance. A tri-motor Ram truck could offer higher towing capacity, quicker acceleration, and a longer range, important features for any truck driver.

Luxury trucks, blending power and eco-friendliness

As the world moves toward cleaner technologies, the luxury truck market is evolving. Stellantis’ tri-motor setup could offer a sustainable solution for buyers who need a powerful truck but want to minimize their carbon footprint.

This system would combine electric efficiency with the power and towing capabilities of a traditional truck. Whether you’re hauling heavy loads or just driving around town, the tri-motor truck could give you the best of both worlds: luxury, performance, and lower emissions.

How the system keeps the battery charged

One of the key features of Stellantis’ tri-motor system is its ability to manage the battery’s charge automatically. The gasoline engine serves as a range extender, providing extra power to recharge the battery.

This means that even when you’re far from a charging station, your vehicle can keep running without issues. The system will ensure that the battery stays topped off, giving you the freedom to drive for longer distances without stopping.

Stellantis moves toward a cleaner future

By adding electric technology to their trucks, Stellantis is taking a big step toward a greener future. The tri-motor system is part of their broader plan to electrify their lineup without sacrificing power or capability.

Electric trucks have the potential to reduce emissions while offering the performance that truck drivers expect. Stellantis is positioning itself as a leader in this transition, proving that electric vehicles don’t have to compromise on performance.

The future of off-roading with electric power

Electric vehicles are quickly becoming a strong contender in the off-road world, and Stellantis’ tri-motor system could take that to the next level. With three electric motors providing torque and precision, this setup could make off-roading smoother and more capable than ever before.

Imagine tackling steep hills, rocky trails, or muddy terrain with the combined power of electric motors. The enhanced torque distribution would allow for better traction, keeping all four wheels powered and moving, no matter the conditions.
