About the 2026 Rivian R1T

The Rivian R1T was the world's first purpose-built electric pickup truck delivered to consumers, beating Ford and GM to market by months. The integrated lockable Gear Tunnel between cab and bed is a unique storage solution that defines the R1T experience.

Advantages

✓Gear Tunnel provides 65 gallons of lockable, weatherproof integrated storage

✓Camp Kitchen (optional) pulls out of the Gear Tunnel — a truly adventurous feature

✓Up to 14" ground clearance with off-road capabilities that exceed most trucks

✓Quad-motor system with torque vectoring on all four corners

Considerations

✗$69,900 starting price is premium for a truck

✗2.5 mi/kWh efficiency means frequent charging on long hauls

✗Rivian Charging network, while growing, is still below Tesla in coverage density

✗Some early production reliability issues (addressed via recalls)

Ideal Buyer

Outdoor and overlanding enthusiasts who want a truck capable of genuine adventure. Buyers who frequently camp, kayak, or need a mobile basecamp with power and storage.

vs. Gas Equivalent

Competes with Ford F-150 Raptor in adventure capability. Gas equivalent is approximately 18 MPG for an F-150 Raptor.

EV Ownership in Idaho

Idaho has a small but growing EV market, centered on Boise and the Treasure Valley. The state's exceptionally low electricity rates ($0.11/kWh) make it one of the cheapest places in the US to charge an EV.

Incentives & Programs

Idaho offers no state EV tax credit, but federal incentives apply. Idaho Power offers time-of-use plans with off-peak rates that can go even lower. The base $0.11/kWh rate is already competitive with TOU off-peak rates in most states.

Charging Infrastructure

I-84 through Boise is well-covered. North-south stretches (US-95 toward Coeur d'Alene) are improving. Southern Idaho's rural stretches require careful planning. Boise has the best urban charger density.

Grid & Energy Source

Idaho's grid is dominated by hydropower (~65%) from dams on the Snake River and Columbia River system. This makes Idaho EV charging among the cleanest in the US, with among the lowest carbon footprints nationally.

IdahoElectricity Rates & EV Savings

The average residential electricity rate in Idaho is $0.11/kWh, which is below the national average of $0.17/kWh. With a gas price of $3.70/gallon, Idaho ranks as a favorable state for EV ownership.

Cold weather reduces EV range by 20–40% as the battery heats itself and the cabin. Use scheduled departure to pre-heat on shore power before driving. Your Rivian R1T's 135 kWh battery provides up to 328 miles of EPA-rated range. Real-world range may vary by 10–30% depending on temperature, speed, and terrain.
