no more car sick —

The EV startup has reengineered the R1 to make it better to drive, easier to build.

Rivian

In rainy Seattle this week, Rivian unveiled what it’s calling the “Second Generation” of its R1 line with a suite of mostly under-the-hood software and hardware updates that increase range, power, and efficiency while simultaneously lowering the cost of production for the company. While it’s common for automotive manufacturers to do some light refreshes after about four model years, Rivian has almost completely retooled the underpinnings of its popular R1S SUV and R1T pickup just two years after the vehicles made their debut.

“Overdelivering on the product is one of our core values,” Wassym Bensaid, the chief software officer at Rivian, told a select group of journalists at the event on Monday night, “and customer feedback has been one of the key inspirations for us.”

For these updates, Rivian changed more than half the hardware components in the R1 platform, retooled its drive units to offer new tri- and quad-motor options (with more horsepower), updated the suspension tuning, deleted 1.6 miles (2.6 km) of wiring, reduced the number of ECUs, increased the number of cameras and sensors around the vehicle, changed the battery packs, and added some visual options that better aligned with customizations that owners were making to their vehicles, among other things. Rivian is also leaning harder into AI and ML tools with the aim of bringing limited hands-free driver-assistance systems to their owners toward the end of the year.

  • Usually, an automaker waits four years before it refreshes a product, but Rivian decided to move early.

  • There are two capacities of lithium-ion battery, and an optional lithium iron phosphate pack with 275 miles of range is on the way.

  • Rivian’s R1 still looks friendly amid a sea of scary-looking SUVs and trucks.

While many of these changes have simplified manufacturing for Rivian, which as of Q1 of this year lost a whopping $38,000 on every vehicle it sold, the company has continued to close the gap with the likes of BMW and Mercedes in terms of ride, handling, comfort, and efficiency.

On the road in the new R1

We drove a new second-gen dual-motor 665 hp (496 kW), 829 lb-ft (1,124 Nm) R1S Performance, which gets up to 410 miles (660 km) of range with the new Max Pack battery, out to DirtFish Rally School in Snoqualmie in typically rainy Seattle weather. On the road, the new platform, with its revised suspension and shocks, felt much more comfortable than it did in our first experience with an R1S in New York in 2022.

The vehicle offers modes that allow you to tackle pretty much any kind of driving that life can throw at you, including Sport, All Purpose (there’s no longer a “Conserve” mode), Snow, All-Terrain, and Soft Sand, alongside customizable suspension, ride feel and height, and regen settings. The R1S feels far more comfortable from all seating positions, including the back and third-row seats. There’s less floaty, car-sick-inducing modulation over bumps in All-Purpose, and Sport tightens things down nicely when you want to have a bit more road feel.

One of the big improvements on the road comes from the new “Autonomy Compute Module” and its suite of high-resolution 4K HDR cameras, radars, and sensors that have been upgraded on the R1 platform. The new R1 gets 11 cameras (one more than the first gen), with eight times greater resolution, five radar modules, and a new proprietary AI and ML integrated system that learns from anonymized driver data and information taken from the world around the vehicles to “see” 360-degrees around the vehicle, even in inclement weather.

While the R1S has had cruise control since its launch, the new “Autonomy” platform allows for smart lane-changing—something Rivian calls “Lane Change on Command” when using the new “Enhanced Highway Assist” (a partially automated driver assist), and centers the vehicle in marked lanes. We tried both features on the highways around Seattle, and the system handled very rainy and wet weather without hesitation, but it did ping-pong between the lane markers, and when that smart lane change system bailed out at the last minute, the move was abrupt and not confidence-inspiring, since there was no apparent reason for the system to fail. These features are not nearly as good as the latest from BMW and Mercedes, both of which continue to offer some of the most usable driver-assist systems on the market.

With the new R1 software stack, Rivian is also promising some limited hands-free highway driver-assistance features to come at the end of the year. While we didn’t get to try the feature in the short drive to DirtFish, Rivian says eye-tracking cameras in the rearview mirror will ensure that drivers have ample warning to take over when the system is engaged and needs human input.

The Motiv Argo is a new modular medium-duty electric truck

looks futuristic —

Motiv has made electric powertrains for medium-duty vehicles since 2009.

Medium- and heavy-duty vehicles account for about 23 percent of US vehicle emissions. That’s much less than the amount of greenhouse gases emitted each year by light-duty vehicles, but if anything, businesses can often have a clearer case for electrification, whether that’s to save money on annual running costs or to meet ESG goals. The annual Advanced Clean Transportation Expo is currently underway in Las Vegas, and yesterday Motiv Electric Trucks revealed the production version of its new modular medium-duty EV, the Argo.

Motiv has been around since 2009 and has been selling electric powertrains for school buses, step vans, box trucks, and even trolleys. Now it’s branching out with its own vehicle, the modular Argo, which is capable of carrying up to 14,000 lbs (6,350 kg) with a range of up to 200 miles (321 km).

“Overnight we’ve moved from a company primarily serving a narrow slice of the $20 billion medium duty truck market to one that can serve nearly that entire market,” said Motiv CEO Scott Griffith. “The launch of Argo is a transformational moment for our company as we can now offer more vehicles and options to help more fleet customers meet their sustainability goals.”

The Argo looks somewhat futuristic—certainly in comparison to a step van or box truck—and has an integrated cab-chassis design. Argo says that maximizing visibility was a key design target, with low curbside windows, plus the option of side-view cameras in addition to passive mirrors. There are also design features meant to improve driver safety, too, including safety railings and self-cleaning interior steps to help prevent what Motiv says are the most common operator injuries.

  • “Many fleet customers have pointed out the simple design of our new Gen 6 architecture, how much less copper we use and how well cables are routed, how easy it is to access our patented smart hub and how easy our software is to integrate; this apparent simplicity took years for us to optimize and now our customers can finally reap the benefits,” said Jim Castelaz, Motiv founder and CTO.

Motiv developed the Argo’s powertrain together with the Japanese company Nidec. Although Nidec originally designed the electric motor to operate at 800 V, Motiv developed a new control algorithm that allows it to run at 350 V instead, which it previously told Ars is more cost-effective. The battery pack uses a lithium iron phosphate (LFP) chemistry and was developed together with Our Next Energy.

The Argo comes in a range of wheelbases, from 178 inches (4,521 mm) to 252 inches (6,400 mm), with dock-height and lower profile options for almost any application you might want a medium-duty truck for, Motiv says. Pricing will be based on how many trucks a customer orders as well as the specifications, but Motiv told Ars that it “will be price competitive with other Class 6 electric trucks.”
