How Far Can You Tow With an Electrical Truck?

As increasingly sorts of autos turn into electrified, a persistent query has hung over all-electric pickup vans: What occurs once you tow? Now that the primary mass-production, long-range, all-electric pickup truck—the 2021 Rivian R1T—is available on the market, we will discover out.

With greater than 100 years of gas- and diesel-powered towing on the books, the world is fairly conversant in what occurs once you put a trailer on the hitch. Gasoline economic system whereas towing is, in comparison with driving round empty, abysmal. Pulling hundreds of additional kilos, particularly at freeways speeds, takes a variety of further gasoline. The identical applies to battery-powered autos, which at the moment haven’t got the posh of a gasoline station at each freeway exit.

Though we have towed with electrical SUVs prior to now, they might solely give us a basic thought of what to anticipate. SUVs simply cannot tow as a lot as full-size pickups and are not actually supposed to frequently, anyway. Pickups, although, want to have the ability to absolutely make the most of their beds and tow hitches day in and time out if the proprietor calls for it. Their homeowners, in flip, must know what the car’s real-world limits are, so we hitched up a 9,000-pound trailer to a brand new Rivian R1T throughout our Truck of the 12 months competitors to search out out.

The Truck and Trailer

Our R1T was a Launch Version outfitted with the usual 135-kWh battery and 21-inch highway wheel and tire bundle, EPA-rated at 314 miles of vary. Our trailer was a flat tilt-bed automotive hauler loaded with the Filth Each Day Chevrolet Astro van we stole out of the corporate storage lot, with the van itself loaded with 16 100-pound horse stall mats for ballast. In complete, the trailer weighed 8,992 kilos and was hitched to our 7,134-pound R1T for a gross mixed weight of 16,135 kilos. All R1Ts have a most typical towing ranking of 11,000 kilos, and the corporate claims pulling that load will minimize your vary by 50 p.c to roughly 159 miles.

Take a look at Run

Earlier than we hit the open highway with the truck loaded as much as 82 p.c of its most towing functionality, we would have liked to get a really feel for the way it tows. Weighing over 7,000 kilos empty, we did not count on it to get pushed round by the trailer, however that may rely upon extra than simply weight, and also you by no means understand how a car goes to tow till you attempt it.

Closed-course testing revealed the R1T to be very steady whereas towing the trailer loaded to 7,500 kilos. The air springs and cross-linked hydraulic anti-roll bars did a wonderful job of countering the forces utilized by the trailer whereas cornering, accelerating, and braking. The physique management lent a sense of solidity and confidence whereas towing.

Instrumented testing revealed the truck was nonetheless capable of speed up to 60 mph from a cease in 7.5 seconds, solely 4.4 seconds slower than unladen. For security causes, we do not measure emergency stopping with a trailer, however we did discover Rivian’s integration of the trailer brake controller into the instrument cluster and steering wheel controls well-executed and simple to make use of.

Easing In

Actual-world testing is completely different than a proving floor, so to get an thought of how public roads, site visitors, and hills would have an effect on the R1T whereas towing, we began with a brief 39-mile run from California Metropolis, California, as much as Tehachapi, with the trailer loaded as much as its full 8,992-pound take a look at weight. Common speeds could be considerably excessive because of a route of largely desert again roads and state highways. All autos with trailers are legally restricted to 55 mph in California, so we caught to the velocity restrict for this primary leg (a lot to the frustration of each different car with a trailer on that stretch of freeway).

Extra essential, the elevation achieve between the 2 cities is 1,942 ft, climbing from 2,018 to three,960 ft, placing further pressure on the truck and its battery.

Beginning with a full battery, we hit the highway. It did not take lengthy to understand an electrical truck’s biggest towing benefit: instantaneous torque. Whether or not leaving a cease, passing a slower truck, or going up a hill, the R1T all the time has far more energy than it must rapidly and safely get the job achieved, even with practically 9,000 kilos on the hitch. Likewise, altitude had zero impact on the truck’s efficiency.

Placing the truck into Towing mode mechanically revises your estimated vary, which is itself based mostly on how you’ve got been driving currently. We weren’t shocked, then, to see our vary drop from practically 300 miles in default All Objective mode to lower than 200. Thirty-nine miles later, we arrived with 136 miles of vary remaining and the battery at 55 p.c. Assuming the speed of power utilization remained about the identical, that will give us a complete vary of 175 miles, or 56 p.c of its EPA-rated vary. That is barely higher than Rivian’s steerage, which is spectacular contemplating the second half of the drive was all uphill.

The Large Tow Take a look at

After two extra days of testing round Tehachapi, it was time for the actual take a look at: returning the truck and trailer to Los Angeles. In keeping with Google Maps, probably the most direct path to our vacation spot was 123 miles. Given how exhausting we would been working the truck the previous few days, we weren’t shocked to see the estimated vary drop from 292 miles to 123 miles, however we weren’t completely happy about it, both. That is simply 39 p.c of the EPA-rated vary. And, , precisely how far we would have liked to go.

The excellent news was, we would be dropping a complete of three,829 ft in elevation over that drive, dropping from practically 4,000 ft to only above sea stage. The dangerous information was we would must climb over 4 mountain passes within the course of, together with one lower than 10 miles from the vacation spot when the battery would already be low. It actually made us want we had time to attend for the battery to get all the way in which to 100%, however 97 p.c must do.

Simply to make issues extra practical, we determined to disregard the 55-mph towing velocity restrict. Most individuals do anyway, and it is not a factor in most states. We felt snug cruising within the 65- to 75-mph vary with this load.

With a mix of gravity and punctiliously wielded regenerative braking, we had been capable of show the vary estimate fully mistaken, and 123 miles later, we glided simply into our vacation spot with 47 miles of vary remaining and the battery at 40 p.c. Assuming once more our power utilization remained  about the identical, this might point out an precise vary of 170 miles, once more consistent with Rivian’s official steerage.

Trailer unhitched and driving mode switched again to the default All Objective mode, our estimated vary jumped to 90 miles.

The Takeaway

Towing roughly 9,000 kilos with a Rivian R1T decreased our driving vary by 45 p.c on common, barely higher than Rivian’s estimate of a 50 p.c discount when towing the utmost 11,000 kilos the truck is able to. Our vary dropped from an EPA-estimated 314 miles to as little as 170 miles. For context, that is 30 miles farther than a typical Nissan Leaf can cowl on a single cost however lower than most different EVs.

For extra context, consider your outcomes will fluctuate tremendously for all the identical causes they might when towing with a gas- or diesel-powered truck. How far you may make it on a cost will rely upon the load of your trailer, the form of your trailer and any load it is carrying, the roads you drive on, the speeds you drive at, and the way you drive. Our blocky outdated van sitting excessive on a flatbed trailer was an aerodynamic brick, however the majority of our route was a gradual descent from elevation.

In fact, your vary can also be a operate of the general public EV charging community. If wanted, we may’ve stopped at a public DC quick charger and juiced up the truck and prolonged our vary considerably. This selection at the moment has drawbacks, although. In contrast to gasoline pumps, EV chargers are virtually by no means constructed for pull-through site visitors, making it tough to park a car with a trailer at a charger with out unhooking the trailer. Second, even the very best DC quick charging remains to be slower than a gasoline pump. Rivian says you possibly can add 140 miles of vary in 20 minutes, and as with all EVs, charging is not linear, so it’s going to take greater than 20 minutes so as to add the following 140 miles of vary. Regardless, determine an hour to cease and cost, all stated and achieved.

Sure, you possibly can completely tow with an electrical truck, however no less than within the case of the Rivian R1T, count on to lose as much as half your driving vary as you method its most towing functionality, a lot as you’ll in a gas- or diesel-powered truck. If it’s essential tow greater than 150 miles, plan to hit a public charger alongside the way in which and provides your self ample time to refill.
