Who it suits. Drivers wanting a 370-mile electric SUV range Buyers who need part-time four-wheel drive Owners planning around 240-volt charging

The R1S Premium Long Range (20in AT) makes sense for buyers who prioritize a long electric driving distance in an SUV body. Its EPA estimate covers 370 miles, while the yearly electricity figure is $950. Charging requires 15 hours at 240 volts, so home-charging time matters as much as range. Part-time four-wheel drive is included, and the combined rating is 78 MPGe. If those figures fit your driving pattern, this model offers a clear operating profile; if charging speed is your main concern, examine that 15-hour figure closely.

What it is

This 2027 Rivian R1S is a standard sport utility vehicle with part-time four-wheel drive. It runs on electricity, uses a 264 kW ACPM motor, and has an automatic transmission.

The model’s defining figure is its 370-mile EPA range. That is the estimated distance on a full charge under the EPA rating.

The R1S returns 78 combined MPGe and uses 43.22 kWh per 100 miles. Its 240-volt charge time is 15 hours.

What it costs to run

EPA estimates the R1S will use $950 worth of electricity in a year. That is the listed annual fuel cost for this electric model, not a purchase price.

Trade-offs

The 370-mile range is paired with 43.22 kWh per 100 miles, and a 240-volt charge takes 15 hours. Those are the main operating figures to weigh against the range.

Part-time four-wheel drive is part of the drivetrain, while the EPA class identifies the vehicle as a standard sport utility vehicle.

Verdict

Choose this R1S if its 370-mile EPA distance fits your routine and you want electric power with part-time four-wheel drive. Budget around $950 a year for the EPA’s electricity estimate. The 15-hour 240-volt charging time deserves attention before buying, especially if your schedule depends on quick turnarounds. Its 78 MPGe combined rating and 43.22 kWh-per-100-miles use give you the core running numbers; the remaining decision is whether this range, body style, and drivetrain match your needs.
