2026 RAM 1500 REV: Range, Payload & Charging Guide for Inland Empire Buyers

The 2026 Ram 1500 REV takes a different path to an electric truck. Rather than relying on one large battery, it pairs a battery with an onboard gasoline generator. The result drives like an EV day to day while keeping the long-distance freedom of a gas truck. Ram targets an estimated 145 miles of electric-only driving on a full charge. That extends to a targeted total of up to 690 miles once the onboard generator and fuel tank are factored in, according to Ram.

Because the generator steps in when the battery runs low, the REV is designed to ease the range anxiety that keeps many Inland Empire drivers from going electric. That holds whether you are handling daily errands, a weekend trip, or a full workday.

A quick note before the details: the Ram 1500 REV is a new, pre-production model with projected 2026 availability. The figures below are manufacturer targets and estimates; official EPA ratings and final specifications will be confirmed closer to launch.

How the Range-Extended Powertrain Works

The 2026 Ram 1500 REV uses a series-hybrid, range-extended electric system. A liquid-cooled 92-kWh lithium-ion battery works with a 130-kW generator spun by a naturally aspirated 3.6-liter Pentastar V6. The key detail is that the gas engine has no mechanical connection to the wheels — its only job is to turn the generator, which sends electricity to the motors or recharges the battery on the move.

Two electric motors, one on the front axle and one on the rear, provide standard all-wheel drive. Ram targets a combined 647 horsepower and 615 lb-ft of torque, and a 0–60 mph time of about 4.5 seconds, per Stellantis. Drivers can tailor the truck through five selectable dynamic drive modes:

• Auto — balances efficiency and performance for everyday driving.
• Sport — sharpens accelerator response for quicker, more agile handling.
• Tow — optimizes power delivery and control for hauling heavy trailers.
• Snow — manages power for better traction on slick surfaces.
• Off-road — adjusts suspension and power distribution for loose terrain.

Separately, the e-shifter includes power-management settings — Electric+ (prioritizes battery-only driving), E-Save (preserves the current battery charge by running the generator), and Eco (optimizes for efficiency) — that let drivers control how the battery and generator work together, per Stellantis.

Targeted Specifications at a Glance

Towing Capacity and Heavy-Duty Capability

The REV is built for real work. Ram targets a maximum towing capacity of up to 14,000 pounds and a maximum payload of up to 2,625 pounds. Those numbers are supported by an all-new high-strength steel STLA Frame, eight-lug wheel hubs, and a standard air suspension that levels the truck under load.

Towing a heavy trailer draws more energy, so electric-only range will fall when you are pulling near the limit, as it does with any electric truck. The difference here is that when the battery runs low, the V6 generator engages automatically and the 27-gallon fuel tank keeps you moving, so you can complete a long haul without hunting for a fast charger.

For drivers hauling a horse trailer around Norco or heading out from the shop, that combination of electric smoothness and gas-backed range is the whole point of the range-extender design.

Maximum towing and payload capacity figures are based on properly equipped vehicles and vary by configuration. Do not exceed any weight rating. See your owner’s manual and the vehicle’s door-jamb label for specific capacities.

Charging at Home and on the Road

DC fast-charging figures are per Ram. The REV also supports bidirectional charging. During a power outage, it can send electricity back to your home, providing up to 30 days of emergency backup power when using smart energy rationing.

Choosing a Trim

The 2026 Ram 1500 REV is expected to launch in three trims:

Available Hands-Free Active Driving Assist is expected on the higher trims, which can make Inland Empire highway commutes — such as the drive from West Covina toward Los Angeles — noticeably easier.

Frequently Asked Questions

What warranty coverage is expected for the 2026 Ram 1500 REV?

Ram’s new-vehicle warranty includes a 3-year/36,000-mile basic limited warranty and a 5-year/unlimited-mile corrosion warranty covering rust-through perforation. For 2026, Ram extended powertrain coverage to 10 years/100,000 miles on its gas and diesel trucks and vans — but that program excludes electrified models. The REV is expected to carry separate powertrain and high-voltage battery terms, which Ram will confirm at launch; EV battery components typically carry the industry-standard 8-year/100,000-mile coverage. See Ram’s warranty details for current coverage.

Is roadside assistance included?

Ram includes 24/7 roadside assistance on new vehicles. You can reach Ram Roadside Assistance at 800-521-2779 for towing and recovery.

Does the V6 generator need special maintenance?

The 3.6-liter Pentastar V6 serves only as a generator and follows conventional gas-engine maintenance such as oil and filter changes. Because it runs intermittently rather than constantly, engine wear is reduced, though routine inspections remain important.

Warranty coverage depends on the terms of the specific warranty agreement and varies by model, powertrain, and configuration. See Ram’s official warranty terms for current coverage. Consumer warranty rights may also be protected under applicable federal and state law.
