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 announced its Ramcharger extended-range electric truck. As we previously knew, this model will feature the company’s 3.6-liter V-6 engine connected to a generator, which produces power for the vehicle's battery along with its dual electric motors. On Monday, the carmaker provided further details about these systems working in tandem, revealing an estimated total 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 maintaining 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 three different operational modes for the driver to manage how electricity—from either the battery or the generator—is utilized. These modes include: Electric+, E-Save, and Eco.

If you're looking for an entirely electric vehicle driving experience,Electric+ is the setting for you. Just press the button, and the combustion engine won’t activate until the battery’s available energy has been used up. According to Ram, this typically covers about 140 miles under regular use conditions. However, aggressively pressing the accelerator or hauling up to 14,000 pounds can cut down this distance considerably. Regardless of how firmly you step on the gas, though, the internal combustion engine remains inactive in Electric+ mode until the battery runs out completely.
When the engine starts up, the generator supplies electricity to the motors. In addition, the battery’s reserves contribute energy, ensuring the Ram operates at peak performance until the 27-gallon fuel tank empties. Once refilled, you can resume driving; however, the generator cannot fully recharge the battery. To restore it to maximum charge, you must connect it to an external power source.
The E-Save mode starts the engine whenever necessary. Although this doesn’t boost your horsepower, it keeps your battery’s charge stable as you operate the vehicle. Should you begin with a fully charged battery and activate E-Save mode, the charge level will remain constant until the fuel supply depletes. Conversely, if you initiate E-Save mode when your battery charge drops below half, the system will gradually restore the battery to a 50% charge level.

What makes this mode appealing? Ram views it as an opportunity to maintain certain electric-driven features at particular stages during 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 to preserve some charge for quieter operation down the line.
The last setting is Eco. Ram did not provide extensive details about this mode except to say that it’s ideal for saving energy. When in Eco mode, the engine output is capped, and features such as heating and air conditioning are toned down to save power. It remains uncertain whether using Eco mode is necessary to reach 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 option helps maximize both fuel and electric efficiency.
“I believe the [Ramcharger] will become a game-changer in this sector,” stated Ram CEO Tim Kuniskis at the Ramcharger media unveiling. “That’s precisely why we felt compelled to present it to you at the earliest opportunity. Unlike a mere slideshow, this vehicle is genuine and set to arrive imminently.”
Keep an eye out for the 2026 Ram Ramcharger EREV, which is expected to make its appearance during the latter part of this year.
