Questions people ask about the Rivian R1T AT
How many kWh per 100 miles does a Rivian R1T AT use?
The Rivian R1T AT uses 51.85 kWh per 100 miles on the EPA combined cycle, which works out to 1.93 miles per kWh.
How big is the Rivian R1T AT battery?
Its usable battery capacity works out to roughly 129.3 kWh. EPA does not publish battery size directly, so this is calculated from EPA range (277 miles) and rated energy use, corrected for charging losses — expect a few kWh of error against the manufacturer figure.
How much does it cost to charge a Rivian R1T AT at home?
About $25.11 for a full charge at the U.S. average residential electricity price of 19.42¢ per kWh, or $10.07 per 100 miles. Over a year at 12,000 miles that is $1,208. In Nevada the same driving costs $816; in Hawaii it costs $3,280.
How long does a Rivian R1T AT take to charge on a 240V charger?
EPA rates it at about 12.5 hours for a full charge on a 240-volt (Level 2) charger. A standard 120-volt household outlet takes roughly five to six times longer; DC fast charging is far quicker but costs considerably more per kWh than charging at home.
Is a Rivian R1T AT cheaper to run than a gasoline car?
On fuel alone, yes. A Rivian R1T AT costs about $10.07 per 100 miles in electricity. A typical new gasoline full-size pickup manages 18 MPG, which at $4.32 a gallon costs $23.99 per 100 miles — $13.92 more. Over 12,000 miles the difference is $1,671 a year in the EV's favour. This compares fuel only — not insurance, depreciation, maintenance or your state's EV registration fee.

Almost identical energy use
These use within a fraction of a kWh per 100 miles of the Rivian R1T AT, so running cost is effectively a wash between them — the decision comes down to everything else.

Where these numbers come from
Energy use per 100 miles is 3,370.5 ÷ MPGe, because EPA
defines MPGe against 33.705 kWh per gasoline gallon equivalent. EPA meters
that energy at the wall, so charging losses are already included.
Usable battery size is EPA range × kWh per 100 miles ÷ 100 ×
0.90. The 0.90 corrects for the fact that EPA measures energy at the wall but
measures range from the pack; without it the estimate runs about 10% high.
It is an estimate, not a manufacturer specification — expect a few kWh of
error either way.
Cost assumes home charging at the state's average
residential electricity price (EIA, May 2026) and
12,000 miles a year. Public DC fast
charging costs considerably more; time-of-use plans can cost less.
The petrol comparison uses the median combined MPG of
current regular-gasoline, non-hybrid cars in this car's own EPA vehicle class
— not an all-car average — priced at the U.S. average retail price from the
EIA weekly series. It counts fuel only.
