Inside Rivian’s plan to challenge Detroit and electrify the American truck & SUV
Nearly one year ago, McLaren’s top engineer departed the British supercar-maker for a relatively unknown EV startup, Rivian, located 3,000 miles away in Plymouth, Michigan. That engineer, Mark Vinnels, was a founding board member of McLaren and led its engineering team as executive program director for 14 years as they created an entire line of supercars from the ground up. While leaving ultra-high-performance supercars behind seemed crazy at the time, a whole band of McLaren engineers have now followed Vinnels to build world-class electric SUVs and pickups at Rivian.
When Rivian’s CEO, RJ Scaringe, hired Vinnels last November as Executive Director of Engineering and Programs, he tasked him with a familiar mission: build a world-class team and bring their first vehicles to production. Now, Scaringe and Vinnels have attracted engineers across the entire industry, including a whole host of fellow ex-McLaren engineers. From exterior lighting to software and electric propulsion, Rivian’s British talent runs deep.
“These are all truly world-class people, and we had a great team (at McLaren) and we were able to do great things,” Vinnels told Teslarati. “I think a lot of them were motivated in exactly the same way I was.”

Vinnels landed himself at Rivian after a mutual friend, and Rivian board member, Antony Sheriff, insisted that he meet with Scaringe and see what Rivian was working on. “I was super impressed with what I saw, with him (Scaringe) as an individual, and the vision for the company,” he recalled. “From a personal perspective, I had a really interesting opportunity to be involved in something pretty groundbreaking, again.”
While Vinnels had received a variety of job offers from startups over the years, he was particularly impressed by Rivian’s technical achievements and level of funding available. “The concepts were pretty advanced, in terms of the battery, package, detail of the module,” Vinnels said.
Rivian has raised $500M to date from a variety of equity and debt investors. The company has largely been quiet about specific funding deals, but its’ main backers include Sumitomo Corporation of Americas, a US branch of a Japanese conglomerate, and Abdul Latif Jameel, a Saudi Arabia-based family-owned business with close ties to Toyota.
Since Vinnels joined last year, three VPs and three directors have left McLaren to join Rivian, along with several other engineers. While some of these new hires have moved to Rivian’s hubs in the US, the company has recently opened up a development center in the UK.
“The type of people at McLaren are naturally attracted to companies like Rivian, because it’s all about innovation, breaking new ground, doing stuff that is new. How do you attract interesting, dynamic, well-educated engineers; give them great interesting, intellectual, challenging technical problems and a respectable amount of funding to achieve their goals,” Vinnels said. “I think that’s why these people are attracted to what we are doing here. It’s kind of flattering and nice that these guys are making the same decision that I did to come over and work on this great program.”

According to some within Rivian, the biggest recruiting weapon Rivian possesses is Scaringe himself. “People come into the company and they spend ten minutes with him (Scaringe) and they’re sold,” Michael McHale, Director of Corporate Communications at Rivian, said. Vinnels claimed a similar effect on recruiting and building supplier relationships.
“They all love the idea of what we are doing,” Scaringe stated in an interview with Teslarati in July. While building supercars seems like an engineer’s dream job, Scaringe found that many see, “the appeal of doing something that is larger volume and a different performance segment.”
With production of their first two cars looming around the corner, Rivian has ramped up hiring significantly, more than doubling their headcount since the start of the year to approximately 500. In addition to hires from McLaren, Rivian has a significant number of people from Tesla, Faraday Future, and the big three Detroit automakers.
Vinnels’ team is tasked with delivering Rivian’s newly developed “flexible electric platform” to market. The skateboard-like architecture, will not only underpin Rivian’s first two vehicles, an SUV and pick-up truck but another four vehicles in development. The overarching design of all-electric platforms is becoming quite standard in the industry, but the intricate engineering within the platform is where the real magic lies.
While Rivian’s battery management systems and module design were nearly complete when Vinnels joined last year, the suspension, motors, and gearbox have undergone a redesign to squeeze out better performance and efficiency. “We can have such a broad breadth of performance, without traditional compromises (compared to internal combustion engines) and a (higher) level of refinement,” Vinnels said.
Rather than spending hundreds of millions of dollars on building their own factory, Rivian has decided to acquire an existing automotive factory. Rivian purchased a former Mitsubishi factory and all of its contents in January 2017 for $16M. The purchase price represents just 1% of the $1.6B investment (in 2018 dollars) Mitsubishi and Chrysler made building the facility in 1988. The plant houses stamping presses, paint lines, body assembly, general assembly, and a few other sub-assemblies. Even in its heyday, the factory never reached its peak production capacity, which is thought to be above 300,000 vehicles per year.

The company’s plant in Normal, IL saw its last vehicle, a Mitsubishi Outlander Sport, roll off the production line in November 2015. But the plant hasn’t been entirely quiet since then. Rivian first occupied the plant in January 2017 and has 65 employees actively maintaining and preparing the facility for production.
This June, Vinnels was splitting his time between engineering meetings and preparing to start “virtual production” at their 2.6M ft² factory. The “virtual production” exercise allows the nearly 100 people from the engineering, manufacturing, and supply chain teams to walk through every part of the manufacturing process before equipment installation is finalized, spotting any potential issues before they arise in production. Rivian completes this on a monthly basis and often includes several suppliers.
“We’ve got enough detail now to discuss and explain with the manufacturing guys exactly how this vehicle will come together on a component level,” Vinnels explained. “So we start with pretty much the first component, for us its some of the components on the body-in-white and we build up exactly how it be built in the production line.” The process reviews each component on a detailed level from design, materials, and build sequence.
At the moment, Rivian is working on refreshing the facility’s stamping lines and plans to overhaul the body lines and paint lines throughout next year. Scaringe stated that the total renovation of the factory will cost roughly $150M.
In preparation for full production at their factory, Rivian has set up a pilot battery-module production line in their Irvine, CA development facility. Scaringe stated that Rivian plans to start production of their battery modules ahead of vehicle production. The company developed their battery modules from the ground up, including the microchips that run their proprietary battery management system. When production spools up, Rivian plans on producing the battery pack from the module level up in their facility in Normal, IL.

Rivian’s battery module is made up of the same sized battery cells that Tesla uses in the Model 3, commonly referred to as 2170, but the physical configuration of the cells differs quite a bit. Though the module is significantly thicker than Tesla’s, with two cells stacked on top of each other, it’s more energy dense by volume and weight. Separating the two levels of cells is Rivian’s cooling systems. Scaringe credits the module’s unique packaging and their custom battery management system for improving efficiency and performance.
The company has declined to give specific production targets, but stated production volume of their first two vehicles would be in the “tens of thousands.” With plenty of room to grow in their current facility, Rivian plans on steadily growing their production volume over the next decade into “hundreds of thousands.”

Just two years ago, when Lucid Motors and Faraday Future were the talk of the town, very few people in the industry had ever even heard of Rivian. Today, the company is considered far more likely to reach production than those same peers. Unlike other automotive startups, Rivian has a sizeable automotive production facility (Faraday Future’s facility was previously a tire factory and has been largely empty for 20 years) and claims to have a more stable source of financing.
From the get-go, Scaringe knew that he would need to find a unique funding strategy to turn his vision into a reality. Instinctively, he leaned on his alma mater, MIT (Massachusetts Institute of Technology), to find potential funding partners. After finding a few potential like-minded partners, Scaringe landed on a partnership with ALJ (Abdul Latif Jameel). ALJ’s owner and chairman, Mohammed Abdul Latif Jameel, is an MIT alumnus, major donor to the school, and a lifetime member of the MIT Corporation.
Rivian has picked up other investors along the way, but after gaining the backing from ALJ, Scaringe focused quite solely on developing the necessary technology and a go-to-market plan that would differentiate the company.
“They’re (Rivian’s investors) committed to allowing us to continue on the steady path of building the business and launching the product,” Scaringe stated. “It’s precisely what’s allowed us to be so quiet, and not have to be out publicly trying to strum up investor dollars; we can be more focused on what we are doing.”
With Rivian’s roots dating back nearly a decade, Scaringe has shown intense patience and an ability to focus on bringing his core vision to fruition. “I’ve dedicated every ounce of energy I have into building the company,” Scaringe said.
Unlike other EV startups, Faraday Future, Lucid, SF Motors, NIO included, Scaringe isn’t placing his bets on creating another Tesla competitor. He’s set Rivian’s sights on a market full of gas-guzzlers: large trucks and SUVs.
Rivian’s reason for focusing on large trucks and SUVs comes twofold, the lack of vehicle-electrification in the segment and the increasing interest from consumers. Scaringe believes that the segment is ripe for disruption and has lacked real innovation for decades.
“It’s an enormous space. It’s where the Detroit three make essentially all of their money; active vehicles, vehicles that have a high-level of function or utility,” he stated. “What we’re doing is we are bringing a level of technology and performance that resets expectations in this space.”
Scaringe is certainly right about one thing; the Detroit automakers derive an incredible amount of money from their trucks and SUVs. Morgan Stanley’s Adam Jonas estimates that 90% of Ford’s profits come from their truck division, which includes the F-150. In 2017, Ford sold nearly 900K F-150’s, each carrying an average selling price of $45,000. GMC’s Denali line, GM’s most luxurious trucks and SUVs, accounted for over 11% of GM’s US sales in 2017, with each car selling for more than $60,000 on average, according to the NYTimes.
Instead of simply electrifying an F-150 or GMC Yukon, Rivian has reimagined the concept of a large SUV or truck. Much like Tesla reinvented the idea of a sedan with the Model S, adding rear-facing seats, front trunk, and large touchscreen, Rivian is set to unveil an SUV and truck that offer unrivaled off-road performance, abundant storage, and supercar-like performance.
“I think we’re going to be showing something pretty special, in terms of its vehicle package,” Vinnels said. Rivian claims the vehicle will have upwards of 400 miles of range, speed to 60 mph in less than 3 seconds, and wade through 3.5ft of water. Scaringe boasts that Rivian’s vehicles are something you’d want to throw your surfboard, skis, or tent in and escape for the weekend.

Rivian’s largest battery pack holds a staggering 180kWh of energy and delivers 400+ miles of range. Additionally, Rivian will offer 105kWh and 135kWh configurations, with a starting price just over $60K. The top of the line battery pack will start just under $90K and will deliver close to 800hp, Scaringe stated on the LACoMotion podcast. More details around the configuration of the vehicle will be available next week at the reveal.
As Porsche, Mercedes, BMW, and Audi play catch up to Tesla’s premium EV lineup, Rivian is working to reinvent an entirely different market. The company is confident that their upcoming vehicles are built for the world of tomorrow and will shake up Detroit’s perspective on electric vehicles. “We aren’t here just build one vehicle; we’re here to build whatever the lifecycle volume is, 250,000 or 300,000 vehicles. We worry just as much about the last one as the first one,” Vinnels said.
After nearly a decade in the shadows, Rivian is preparing to unveil their first two vehicles in Los Angeles next week. “We’re confident that what we are showing is pretty much exactly what we will be delivering to the customer,” Vinnels said. The unveiling of Rivian’s truck, the R1T, will be live streamed from a private event on the 26th, while the SUV, carrying a similar name, R1S, will be unveiled on stage at the LA Auto Show the following day.
“It will be like nothing else,” Vinnels stated.

Tesla Cybercab and Robotaxi’s real advantage won’t be the ride service
For a century, the car has asked the same thing of its owner, which is basically to pay attention. Even the best ride-hailing app like Uber or Lyft only moved the problem into someone else’s hands. You stopped driving, but you still sat in a stranger’s car, while half listening, and wondering whether to take a phone call in the car without being rude. The Cybercab has no wheel, no pedals and no driver. With Grok @bot now live inside it, it becomes something else entirely, and I think that matters more than the fleet count that everyone is tracking.
Grok @bot is an agent, not a voice assistant. A rider signs in once, and from then on can say what they need and watch it happen. Order dinner from a favorite restaurant. Fill the grocery cart. Move money, answer email, adjust a calendar, push a work project forward. Tesla engineer Yun-Ta Tsai confirmed it is enabled across every Cybercab and the rest of the Model Y fleet, and Tesla’s own pitch is that Full Self-Driving handles the commute while Grok handles the errands.
Think about what that does to a thirty minute ride. Uber sells you a trip, while Waymo sells you the same trip in a more private setting. Tesla is selling the thirty minutes themselves, returned to you with an assistant attached. Errands that used to eat a Saturday get done between pickup and drop off. The ride stops being dead time between two places and becomes a place of its own.
Tesla integrates Grok Bot into its vehicles for the ultimate personal assistant
Best of all, your Bots follow you into any Cybercab, and presumably your own Tesla, then logs you out automatically when you step out. Anyone can bolt a chatbot onto a screen, but much harder to own the vehicle, the autonomy stack and the assistant at once. It also quietly ties SpaceX’s Super Intelligence business to Tesla’s fleet, after Tesla converted its xAI stake into SpaceX equity. The relationship between those two companies is getting harder to describe as separate.
This is also where the hard questions start, because an agent that can spend your money in a vehicle other people also ride in needs some answers. How does it handle a voice it shouldn’t trust? What gets recorded, who can see it, and for how long? What happens when a rider leaves halfway through a task?
If Tesla gets those answers right, the scoreboard changes. We have been counting Cybercabs and wait times. The more telling number may be what riders accomplish per trip. That is data almost no one else will ever have, and it is the real reason to watch Grok @bot.

Why Elon Musk’s target date for buying an Optimus robot is harder than it sounds
Musk says China’s magnet export ban cost Optimus months, and robot hands remain shockingly hard.
Elon Musk says China’s export curbs on magnets used in electric motors set back Tesla’s Optimus program by two to three months, and that the robot’s hands remain the hardest part of the project. He made the comments Saturday during a live interview with Tesla Owners Silicon Valley at the X Takeover event at Giga Texas, in front of roughly 2,000 attendees. The Optimus discussion begins around the 49 minute mark of the stream.
On the hands, Musk was blunt and noted that a general purpose humanoid needs fine motor skills that are “incredibly difficult to get right. Shockingly difficult,” he said in the interview. He pointed to a problem he says no one has demonstrated yet: “One of the hardest things also generally is to do precision and force at the same time,” such as driving a small self tapping screw into wood. Touch sensors add another layer, since it is “actually kind of hard to get touch sensors that elastically deform and can handle high cycle life and it won’t just break after a few thousand cycles.”
He also took aim at rival robot videos. “Any complicated looking robot demo, it’s a canned demo. It’s not real,” Musk said, adding that real AI means showing a robot something it has never seen and watching it still cope, the way FSD handles a city it has never driven.
Musk expects the Optimus ramp to be slower than a new vehicle production ramp. “The initial part of that S curve of production ramp is going to be very slow at the beginning,” Musk said, partly because “unlike cars, there’s no pre existing supply chain for robot stuff.” That echoes his July reply on X that Optimus production “will be extremely slow at first, as everything is new.”
The magnet disclosure puts a number on a problem Musk first raised in 2025. He said China “prevented the export of magnets for use in electric motors” and that it “set back the Optimus program by like two or three months.” Then he added: “We had robots with no arms.” Tesla’s fix is to bring the supply chain home. “You’ve got to be able to make all the parts domestically,” he said. Teslarati reported in April 2025 that Musk tied the issue to permanent magnets in the arm actuators, where motors have to be as small as possible.
Tesla Optimus V3 hand and arm details revealed in new patents
Production is moving regardless, with a reported internal goal of more than 1,000 a week by the end of 2026. Teslarati recently covered how Tesla is certifying supply partners in China for Optimus parts, while the company’s hand design has been the subject of new patent filings.
Musk has said he wants Optimus available to the public by late 2027, though Tesla has not confirmed that date or published updated production figures.

Elon Musk drops a Thanksgiving hint about Starship’s biggest test yet
Elon Musk says Starship Flight 15 will try to catch the ship itself, a first.
Elon Musk says SpaceX’s next Starship flight will try something nobody has done before, by catching the ship itself. Speaking to roughly 2,000 people at the X Takeover event at Giga Texas on Saturday, Musk said Flight 15 is about four to six weeks away and “probably launches a little bit before Thanksgiving, is my guess.”
That is a slip from earlier reporting, which had pointed to a launch as early as October 19. Musk explained why the date keeps moving. “We’re making a bunch of improvements to the rocket between every flight,” he said, adding that there are often hundreds, sometimes thousands, of small changes. This time the list is short, “but some of them take a fair bit of work and we’ve got to go inside the tank to make some of these changes.”
“We’re going to try to catch the ship, which is a super big deal,” Musk said. “If we do so, that’ll be the first time that there’s been full recovery of an orbital class rocket.” SpaceX has already caught the Super Heavy booster with the tower’s mechanical arms, and has talked about catching the ship since late 2025, but the upper stage has never been caught.
Musk also laid out what comes after. “The next big milestone would be to refly both the booster and the ship,” he said, describing a Flight 16 where “all parts of an orbital rocket are reflown.”
The reason SpaceX wants this comes down to cost and cadence. Every Starship ship so far has ended its flight in the ocean, and SpaceX expects most of those water landings to end in fireballs. A ship that returns to Starbase intact can be inspected and flown again. SpaceX’s IPO filing, says Starship V3 is designed to deliver 100 metric tons to orbit in a fully reusable configuration, that SpaceX aims to cut the cost to reach orbit by 99% or more versus the historical average, and that tower catches should allow “multiple launches per day.”
The payoff goes beyond cheaper launches. The next generation Starlink V3 satellites are too large for Falcon 9 and can only fly on Starship, which can carry up to 60 per flight. Flight 14 on September 28 deployed the first 26 of them after Starship reached orbit despite an early engine shutdown, as Teslarati reported. Musk blamed engine computer software, and said the heat shield “was extremely robust,” which he claimed in August had solved Starship’s biggest challenge.
NASA’s Moon plans depend on the same capability. NASA’s inspector general has described a lander mission that needs a propellant depot in low Earth orbit and more than 10 tanker flights, with SpaceX targeting one tanker launch every six days. That schedule only works if ships and boosters come back fast and fly again. Also, ship to ship propellant transfer has not been attempted yet.
One interesting hurdle yet to be explored is bringing the ship back to the launch site, with reentry over land, which will undoubtedly come with a lot of aviation safety reviews.
