As Rivian begins accepting orders for its 2026 Quad-Motor pickup truck and SUV, prospects could initially be enticed by the ability and methods the 4 motors in these rebooted EVs can unleash.
In spite of everything, 4 motors delivering a mixed 1,025 horsepower and 1,198 pound-feet of torque — and the power to speed up from a standstill to 60 miles per hour in lower than 2.5 seconds — is difficult to disregard.
However they need to additionally take note of the software program.
“The quad is de facto the top of all the things that Rivian has finished thus far,” Wassym Bensaid, the corporate’s head of software program, informed TechCrunch, rapidly offering a punch record on acceleration, velocity, torque, and an estimated 374-mile vary. “Now that now we have full in-house motors, now we have full management on the stack, {hardware} and software program.”
That management has allowed Rivian to introduce a number of new options, which can roll out through software program updates within the quad-motor this September. (Clients can order the quad-motor trim beginning as we speak with deliveries starting as early as subsequent week, in keeping with the corporate.)
The characteristic that may seemingly encourage essentially the most TikTok movies and Instagram reels is “kick flip,” a characteristic that adjusts the ability to the within wheels and lets the car spin about its heart — even because it’s shifting. Kick flip, which TechCrunch examined throughout a press drive in June, permits a car touring below 20 mph on filth to kick out its again finish and swing it to the best or left with out shifting the steering wheel. The thought is to offer off-roaders the power to make tight activates trails by pushing a button and with out going via the tedious process of a 3-point flip.
Rivian followers and followers would possibly recall a promoted, however by no means launched, characteristic referred to as “tank turn.” Kick flip, which controls energy and tire grip, is the real-world and toned down model of tank flip. Rivian informed TechCrunch tank flip was by no means launched as a result of its founder and CEO RJ Scaringe and others fearful that tank flip would break trails. Not the most effective look for a corporation that has made out of doors actions and preserving the setting a giant a part of its model.
Kick flip may nonetheless be abused if the motive force stayed in the identical spot and continued to spin the car in a circle. Nonetheless, Rivian has positioned some software-powered guardrails on the characteristic, together with limiting the velocity and solely permitting it to spin in filth.
Second-generation overhaul
Rivian first revealed its second-generation quad-motor configuration throughout a Could 2024 press drive in Washington, in a bid to showcase the overhaul of its flagship R1 line. That reboot touched each inch of its insides from the battery pack and suspension system to {the electrical} structure, inside seats, sensor stack, and software program person interface.
The trouble, which has led the corporate to construct extra of its main parts in-house, is geared toward lowering the price of manufacturing and enhancing the efficiency and enchantment of its EVs.
Deliveries of the brand new dual-motor and efficiency dual-motor trims started nearly instantly, with the tri-motor configuration following by August 2024. The quad-motor, which is its costliest and highly effective trim, took one other yr to develop and refine the software program options and embedded techniques, and the way they labored alongside the motors, suspension, and thermal administration, in keeping with the corporate.
And the stakes are excessive that Rivian will get the quad-motor proper. Rivian’s highly-anticipated and cheaper R2 autos aren’t anticipated to enter manufacturing till the primary half of 2026. Rivian is hoping the brand new quad-motor, which begins between $125,990 and $115,990 relying on the car trim, will give gross sales a lift. And the software program is a crucial piece of its bid.
If the 4 motors (one positioned at every wheel) are the center of the second-generation quad-motor, the software program is the mind making all of it work collectively.
Bensaid pointed to the event of superior torque vectoring and balancing algorithms which have been launched within the second-generation quad-motor.
“Give it some thought as tremendous advanced mathematical processing behind the scenes to permit real-time utilization and choices primarily based on info from the 4 wheels after which the 4 motors, whereas clearly maintaining security guards in place,” he mentioned.
What this implies in follow is quite a few sensors on the quad-motor R1S SUV and R1T truck present info on yaw price, steering angles, and different inputs, that are then fed into software program fashions to manage torque. In different phrases, Rivian’s in-house {hardware} and software program work collectively in real-time to distribute energy at every wheel electronically.
Software program meets {hardware}
That has allowed the EV maker to introduce kick flip in addition to different software-meets-hardware options to the quad-motor, together with its “RAD Tuner,” which lets customers change the car’s driving dynamics through the central touchscreen. The RAD Tuner was developed by a workforce of engineers, software program builders, and designers nicknamed the “Rivian Journey Division.”
The origin story started a number of years in the past, in keeping with Bensaid.
“Each time we’d go and take a look at and qualify model of the software program or the automotive, now we have an engineering display screen which is hidden with the key code,” he mentioned. It was right here that early Rivian worker and R2 chief engineer Max Koff and R1 chief engineer Luke Lynch would configure the automotive as they wished — an train that always pushed the autos to new limits. “And that advanced into this concept of constructing this tuner out there to prospects.”
With RAD Tuner, drivers can create their very own custom-made driving mode from scratch or construct upon presets like “Rally” or “Sport.”
“We actually give customers full management via software program in order that they’ll determine their distinctive character of the automotive,” Bensaid mentioned, including this explicit characteristic is de facto meant for professional drivers.
Bensaid emphasised that is greater than a easy change to the person interface that lets drivers tinker round with steadiness, stability, and experience top.
“I believe what’s actually essential is the know-how behind it,” he mentioned. “For instance, this torque steadiness, the truth that we’re in a position to configure this with a quite simple slider — that is years of engineering improvement to have a really refined torque vectoring algorithm with actually a high-precision management that enables us to vary values whereas we’re driving. It’s technically extraordinarily, extraordinarily tough to do this kind of adjustments.”
The corporate can also be rolling out a launch cam characteristic, which makes use of an exterior digicam recording to routinely seize so-called “Launch Mode,” which that may catapult the brand new R1T quad-motor from a standstill to 60 miles per hour in lower than 2.5 heart-pumping seconds. Customers can replay the movies, view real-time stats like velocity and distance overlays calculated by in-house controls software program. Customers can even export movies to a cell gadget through USB port to avoid wasting and share.
NACS charging and extra
The 2026 R1T and R1S autos, together with the quad-motor, additionally come in-built with the North American Charging Normal, which was initially developed and popularized by Tesla.
This offers homeowners of the 2026 fashions entry to Tesla’s huge community of quick chargers, often known as Superchargers. Rivian can also be supplying quad-motor prospects with a complimentary CCS DC adapter, which was the long-standing EV charging customary till not too long ago, permitting them to plug into different networks.
As a part of this {hardware} improve, the corporate has additionally up to date its software program, particularly the EV charging journey planner characteristic. Now, when a buyer opens the journey planner and selects a NACS station, the data is up to date within the journey planner to replicate that they don’t want an adapter.
