Rivian has modified 600 elements on its R1S SUV and R1T pickup truck in a bid to drive down manufacturing prices, whereas bettering efficiency of its flagship automobiles.
The tip aim, which can play out over the approaching yr, is an existential one. Rivian misplaced about $38,784 on each car it delivered within the first quarter of 2024, in accordance with its earnings report. And the automaker gained’t have the brand new, cheaper R2 SUV on the highway till the primary half of 2026.
That leaves Rivian with one route: promote extra R1S and R1T automobiles with out dropping cash.
The clock begins now. Rivian has just lately began producing the second-generation R1T and R1S, with the primary deliveries starting as early as this week.
The results of Rivian’s second-generation reboot is an all-electric truck and SUV with improved experience high quality, extra highly effective drivetrain choices and different bells and whistles, together with an electronically tinted sunroof and a so-called “launch mode” that may catapult the brand new R1T quad-motor trim from a standstill to 60 miles per hour in lower than 2.5 heart-pumping seconds.
However you wouldn’t know any of this simply by wanting on the second-generation EVs.
Rivian has left the outside of the second-generation R1 line principally untouched — aside from a brand new lighting function that gives a charging standing bar throughout the entrance, Storm Blue paint shade and wheels — a choice that executives instructed TechCrunch was intentional.
As an alternative, Rivian has centered its efforts on remodeling the center, altering the whole lot from the battery pack and suspension system to {the electrical} structure, inside seats and sensor stack. There’s even a redesigned software program person interface that gives detailed illustration-like graphics utilizing Unreal Engine in addition to deeper integration with Apple and Google.
“Some changes are small, some changes are big, but every single aspect of the experience of the R1 will improve with this platform,” Rivian’s head of software program, Wassym Bensaid, instructed reporters in a media briefing forward of the official launch.
Vertical integration is the underlying theme right here. Rivian nonetheless has suppliers. However its engineers, designers and manufacturing facility staff are answerable for making extra elements of the R1 EVs than ever earlier than.
Rivian now designs, engineers and makes its motors in home, for instance. The corporate can be answerable for redesigning a warmth pump-based thermal system to enhance rider temperature consolation and saving vary, and for growing a brand new electrical structure and compute platform that reduces the variety of digital management models (ECUs) used to regulate the car from 17 completely different ECUs in its first era to seven. This new zonal structure permits Rivian to chop greater than 1.6 miles of wiring from every car — a 44-pound weight financial savings — and to construct its automobiles quicker, in accordance with director {of electrical} techniques Kyle Lobo.
Rivian says it even internally developed the 11 new high-resolution cameras that, together with 5 radar, make up its notion stack and assist its security and superior driver help system.
Drivetrains and batteries
The second-generation Rivian R1 lineup has 4 major configurations: dual-motor, efficiency dual-motor, tri-motor and quad-motor. As soon as a buyer strikes past the drivetrain, there’s an array of battery pack choices and different options that pushes the value tag ever greater. Rivian has additionally redesigned the battery modules within the massive and max battery packs, which executives say make them simpler to construct and repair.
Each the dual-motor and efficiency dual-motor drivetrains may be configured with three completely different battery packs. The bottom model, the dual-motor with a typical battery pack, begins at $69,900 for the R1T and $75,900 for the R1S. Notably, this model is outfitted with a lithium-iron phosphate-based battery that gives an EPA-estimated 270 miles of vary.
From right here, the battery ranges and the costs tick greater with the dual-motor massive pack and dual-motor max pack trims. The R1T dual-motor and efficiency dual-motor with a max pack will get 420 miles of vary. The R1S, in an analogous configuration, can journey an estimated 410 miles on a single cost.
Rivian has dialed up the choices by including a tri-motor drivetrain trim — solely out there with the max battery pack — that makes use of two motors within the rear and one within the entrance. This combo delivers 850 horsepower, 1,103 pound-feet of torque and a zero-to-60 mph time of two.9 seconds. The tri-motor max pack trim, which has an estimated vary of 380 miles, begins at $99,900 for the R1T and $105,900 for the R1S.
Rivian rounds out its choices with a quad-motor max pack trim, which delivers an eye-popping 1,025 horsepower, 1,198 pound-feet of torque and an off-the-line to 60 mph acceleration time of lower than 2.5 seconds when utilizing the so-called “launch mode” function.
Google, Apple and autonomy
Rivian has put effort in direction of growing and bettering its personal software program stack, which incorporates the whole lot associated to real-time working techniques (RTOS) that handle the automotive, comparable to thermal dynamics, ADAS and security techniques, in addition to one other layer associated to the infotainment system.
Engineers use free RTOS and protected RTOS as the premise of its working system for car controls.
In the meantime, Rivian’s infotainment system has two working techniques. QNX is the host working system, which is barely used for security capabilities, and an open supply model of Android Automotive for the whole lot else. Bensaid mentioned the corporate is transferring away from QNX to a Linux-based software program.
On the autonomy entrance, Rivian makes use of a mix of Linux and free RTOS software program.
“It’s been really a continuation; since day one we’ve been super intentional about owning our own ECUs, our own computers, and our own software,” Bensaid mentioned, describing the corporate’s long-term method. “Gen one was ramping up the internal knowledge to get to a domain-based architecture. And now that we have those foundations, we’re able to move to a zonal-based architecture, which is much more challenging from a technical standpoint.”
Solely two firms — Rivian and Tesla — have a real zonal structure, Bensaid claimed.
“This is what the industry is calling software-defined vehicles — a term that is absolutely abused,” he added.
The corporate has additionally developed its personal middleware software program, which communicates with the real-time ECUs, the infotainment ECUs and the cloud.
These deep-in-the-weeds particulars matter as a result of theoretically, Bensaid defined, Rivian can take any perform within the infotainment system and convey it over to a cell phone or a third-party software. In different phrases, this permits for purchasers to have a related automotive and hints that Rivian might develop its personal app retailer whereas sustaining safety.
All of this effort exhibits Rivian’s excessive curiosity in controlling the whole expertise. So, maybe it’s not stunning that Rivian’s second-generation R1 line doesn’t provide the favored smartphone projection options of Apple CarPlay or Android Auto. And it seemingly by no means will, in accordance with Bensaid.
As an alternative, Rivian is working with Google and Apple to combine the merchandise that clients need most: music, maps and messaging. As an illustration, Rivian house owners will now be capable to use automotive keys in Apple Pockets on iPhone and Apple Watch, or with choose Google Pixel units, to unlock and begin up their automobiles or share keys digitally.
Rivian can be launching a brand new subscription service referred to as Join+ that may give clients entry to extra Apple and Google merchandise for $14.99 monthly, or $149.99 yearly. Later this summer season, Join+ clients will be capable to stream video (whereas parked) by way of Googlecast, which incorporates 3,000 apps in addition to entry to Apple Music. Rivian additionally labored with Apple to carry its Spatial Audio with Dolby Atmos to the automotive.
Join+ subscribers may also have entry to Spotify, Tidal and Alexa and have the power to share their WiFi hotspot with as much as eight units.
Rivian mentioned it additionally plans to combine voice assistants Siri and Google Assistant within the automobiles.
The corporate has taken an analogous in-house-is-best method to its “Rivian Autonomy Platform,” which can come normal on all second-gen R1 automobiles and contains 11 cameras, 5 radar sensors and a pc that’s 10 instances extra highly effective than the earlier system.
Rivian might use the phrase “autonomy” however its system is just not self-driving, and even shut. The superior driver help system, which TechCrunch examined, requires the motive force to stay alert with their fingers on the wheel.
The system contains adaptive cruise management, which maintains velocity and distance behind automobiles on the freeway, and a freeway help function that robotically steers, brakes and accelerates on choose highways.
Rivian can be releasing a premium model referred to as Rivian Autonomy Platform+, which can be provided without spending a dime to second-generation R1 clients for one yr. Later this summer season, the system will roll out a lane change on command function that may robotically transfer the car into one other lane when the motive force prompts the blinker.
