How Far Can A Rivian Go On A Single Charge: Rivian R1T and R1S official EPA Range

One of the most anticipated news headlines Rivian preorder holders and fans have been waiting to see is the official EPA range reports. Those reports are out. The long-awaited EPA range and efficiency ratings for the upcoming Rivian R1T all-electric pickup and Rivian R1S SUV are in, and some details are pretty surprising.

In both cases, the R1T electric adventure truck and the R1S electric adventure SUV, the EPA Combined range rating for the Launch Edition versions, with “Large Pack” and 21-inch wheels are about 5% better than Rivian’s initial in-house range estimate of 300 miles (483 km).


The Rivian R1T will be able to go 314 miles or 505 km on a single charge, while the Rivian R1S will go up to 316 miles or 508 km on a single charge. Other versions might get different results based on their battery size, weight, and other factors.
Battery capacities of 135 kWh power these ranges according to initial spec details from Rivian, but the EPA data suggests a battery capacity of 144 kWh total. The other battery options are expected to be 105 kWh and 180 kWh.
These are impressive numbers for the Rivian vehicles considering that the form factor of the truck and SUV are not particularly designed for efficiency. While EPA estimates can’t account for different driving styles, the test cycle is robust enough to provide an accurate benchmark for looking to buy an EV.
Looking at the 2022 Rivian R1T Launch Edition with 21-inch wheels, a Combined range of about 314 miles or 505 km is the estimated range from the EPA. Breaking it down, the EPA Highway range is 7% lower at 292.9 miles or 471.3 km. At the same time, the EPA estimate for city driving is over 5% higher at 331.8 miles or 533.9 km. This is one of the fundamental ways EVs differ from internal combustion engine cars. EVs are much more efficient at low speeds than at high speeds, while internal combustion cars are more efficient at high speeds than at low speeds. That is why the EPA range for highway driving is lower than that for city driving.
When it comes to energy efficiency of the R1T, The combined energy consumption is around 481 Wh/mi or 299 Wh/km. Generally speaking, those numbers indicate that the truck has a very low efficiency as compared to another more aerodynamically conscious designed car like the Tesla Model S at 330Wh/mile. However, this makes sense since the R1T is a large, heavy, and indeed not the most aerodynamic vehicle.
The wheel size also affects the range tremendously. Here are details from Rivian on how the wheel size will affect the range of the R1T.


Quote. “From the hottest places to the coldest, from 130ºF to -25ºF, our battery system was built to explore, delivering an EPA estimated 314 miles of range when paired with 21″ wheels. For 20″ wheels, our estimates show a range reduction of 10-15%, with a 5-10% reduction for 22″ wheels. Estimates may vary depending on driving style and conditions.”
The 20-inch All-Terrain wheels have a 10-15% reduction impact on the overall range. This implies a reduced range of about 267 to 283 miles or 430-455 km.
The 21-inch Road wheels are the wheels used for the official EPA tests, so a range of 314 miles or 505 km.
The bigger 22-inch Sport wheels have a 5-10% reduction on the standard range, implying a reduced range of 283-298 miles or 455-479 km.
In January 2022, the Rivian intends to launch a 400+ mile or 644+ km range version and introduce a 250+ mile or 402+ km range version, which should be the cheapest version of the bunch.
Turning our eyes to the Rivian R1S Launch Edition, the EPA Combined range of that is 316 miles or 508 km. The EPA Highway range is over 6% lower at 296.4 miles or 476.9 km, while EPA City is nearly 5% higher at 331.4 miles or 533.2 km. This car consumes energy at a rate of 488 Wh/mi or 304 Wh/km.

Here are details from Rivian on how the wheel size will affect the range of the R1S.
Quote. “From the hottest places to the coldest — from 130ºF to -25ºF — our battery system was built to explore, delivering an EPA estimated 316 miles of range when paired with 21″ wheels. For 20″ wheels, our estimates show a range reduction of 10-15%, with a 5-10% reduction for 22″ wheels. Estimates may vary depending on driving style and conditions.”
The 20-inch All-Terrain wheels have a 10-15% reduction, hence a reduced range of 269-284 miles or 433-457 km.
The 21 inch Road wheels used for the official EPA tests yielded 316 miles or 508 km.
The 22 inch Sport wheels offer a 5-10% reduction effect on the range hence a reduced range of 284-300 miles or 457-483 km.
Rivian also plans a 250+ mile or 402+ km range version of the R1S. There is no word about the 400+ mile (644+ km) range version of the R1S as of now.
When we compare the range and energy consumption numbers between the two models, it turns out that the R1T has less range than the R1S. That’s not a surprise. However, how is it possible that the R1T has lower energy consumption at the same time? Assuming the same battery and charging system, it might be a bug in the data. However, assuming that the R1S has a bigger battery pack is a more sound assumption.
From the stats, The Rivian vehicles have a higher energy consumption than any other EV on the market. That is because it’s the only EV with an official EPA range estimate in its categories.
Ford’s F-150 Lightning, which isn’t expected to come on the market until spring 2022, has a targeted range of 230 miles in the standard and up to 300 miles in the extended version. The EPA has not issued official ranges for the Ford Lightning.


The R1T and R1S vehicles will be offered in two trims, both of which are offered with the same 135-kWh-pack size. The R1T Explore trim starts at $67,500. The Adventure variant of the R1T, which has a premium interior, starts at $73,000.
The Adventure trim in the R1S SUV starts at $75,500, while the Explore package has a base price of $70,000.

  1. Have any Rivian’s actually been sold ? I have never seen one at all. Are they selling them in Virginia ? I doubt that they are. No Rivian dealership in Virginia that I know of.
