The driver has three operational modes to select from, determining when and how to utilize the truck’s dual power systems.
It has been well over a year since Ram It unveiled its Ramcharger extended-range electric truck. We were aware from the start that this model would feature the brand’s 3.6-liter V-6 engine connected to a generator, which produces power for the vehicle's battery and dual electric motors. On Monday, the carmaker provided further details, revealing greater clarity on how these gasoline and electric parts collaborate to achieve an impressive range of 690 miles.
Our man Kevin Williams I've already informed you about the Ramcharger's 92 kWh power pack. And why is only 70 kWh available for use? By retaining some power as backup, the Ramcharger Always ensures maximum power delivery to the driver, even when the battery’s charge level drops significantly and the generator becomes the only electrical source. This situation should ideally be avoided. However, Ram offers the driver three specific operational modes that determine how the electricity—from either the battery or the generator—is utilized. These modes include: Electric+, E-Save, and Eco.

If you're seeking an entirely electric vehicle experience,Electric+ is the mode for you. Just press the button, and the engine won’t activate until the battery’s available energy is used up. According to Ram, this typically lasts about 140 miles under typical driving conditions. Of course, aggressively pressing the accelerator or hauling up to 14,000 pounds can cut down this distance considerably. Regardless of how firmly you depress the gas pedal, though, the engine remains inactive in Electric+ mode until the battery charge runs out completely.
When the engine starts up, the generator supplies electricity to the motors. In addition, the battery reserves contribute energy, ensuring the Ram operates at peak performance until the 27-gallon fuel tank empties out. Once refilled, you can hit the road again; however, the generator cannot fully recharge the battery. For a complete charge, plugging in is necessary.
The E-Save mode turns on the engine whenever needed. Although this doesn’t boost your horsepower, it keeps your battery’s charge level steady as you operate the vehicle. Should you begin with a fully charged battery in E-Save mode, it will remain fully charged until the fuel supply depletes. However, if you activate E-Save mode when your battery is less than half-charged, it will gradually increase the battery level up to around fifty percent.

What makes this mode appealing? Ram views it as an opportunity to maintain certain electric-driven features during particular parts of a trip, like driving into areas where only emission-free cars are permitted. Rather than depleting the entire battery, one can use the E-Save mode and preserve some charge for quieter operation at another point in the journey.
The last setting is Eco. Ram did not provide extensive details about this mode; he simply mentioned that it’s ideal for saving energy. When using Eco mode, the engine output is capped and features such as air conditioning are minimized to save power. It remains uncertain whether activating Eco mode is necessary for reaching Ram's claimed maximum distance of 690 miles. However, if you’re driving under mild weather conditions—neither extremely hot nor very cold—the Eco mode allows you to maximize fuel efficiency both from gasoline and electricity.
“I believe the [Ramcharger] will become a game-changer within the industry,” stated Ram CEO Tim Kuniskis at the Ramcharger media unveiling. “That’s precisely why we decided to present it to you right away. Unlike a mere slideshow, this vehicle is genuine and set to arrive very shortly.”
Keep an eye out for the 2026 Ram Ramcharger EREV, which is expected to make its appearance during the latter part of this year.
