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.
Elon Musk
How SpaceX Is raising Raptor’s sea-level thrust while holding engine mass steady
SpaceX’s Raptor engine family has steadily increased sea-level thrust while simultaneously reducing mass, turning iterative engineering gains into substantially higher performance for the Super Heavy booster. CEO Elon Musk shed more light on how powerful Raptor 4 will be, and it’s pretty crazy.
Raptor 1 delivered 185 metric tons of thrust at roughly 2,080 kilograms, while Raptor 2 raised that to 230 tons while cutting mass to about 1,630 kilograms. SpaceX data for Raptor 3 lists a target of 280 tons at 1,525 kilograms (with further reductions in associated vehicle hardware), while operational flight ratings have been cited near 250 tons.
This morning, Elon Musk stated that Raptor 4 is expected to reach 300 tons of sea-level thrust at roughly the same mass as Raptor 3. Across these versions, thrust has risen by more than 60 percent from the first engines while engine mass has fallen, producing a sharp improvement in thrust-to-weight ratio. This is a true testament to how great SpaceX engineering has been:
🚀 Elon says Raptor 4 will make 300 tons of thrust at sea level at roughly the same mass as Raptor 3.
How far Raptor has come:
Raptor 1: 185 tf, 2,080 kg
Raptor 2: 230 tf, 1,630 kg
Raptor 3: 250 tf, 1,525 kg
Raptor 4: 300 tf33 on Super Heavy = ~9,900 tf, nearly 3x Saturn V https://t.co/HQDswZhyvL

With 33 engines on SuperHeavy, the jump from earlier versions to a 300-ton Raptor 4 would produce roughly 9,900 metric tons of total liftoff thrust, nearly three times the Saturn V’s approximately 3,400 metric tons from its five F-1 engines.
This is not just a larger number on a data sheet, either, as sea-level thrust is the force available the moment the vehicle leaves the pad. This is when it is heaviest and still deep in Earth’s gravity well and dense atmosphere.
Higher levels of sea-level thrust directly improves the initial thrust-to-weight ratio of the full stack. A higher ratio produces faster acceleration off the pad, which shortens the time the rocket has to spend fighting gravity, and gravity losses during the first minute or two of the flight are a major drain on total available delta-v. Every second shaved off of that early climb preserves more propellant energy for reaching orbital velocity or for carrying extra payload.
Because Super Heavy’s engine count is constrained by vehicle diameter and packing density, increasing thrust per engine is the most straightforward way to raise total liftoff performance without redesigning the booster structure or design.
The same-mass target for Raptor 4 is equally important. Holding engine mass roughly constant while raising thrust improves the engine’s own thrust-to-weight ratio and reduces the structural and propellant mass fraction that must be carried solely to support the engines.
Earlier Raptor iterations also simplified or eliminated extensive vehicle-side hardware such as heat shields. These gains compound: more force for less installed mass leaves additional capacity for propellant, payload, or operational margins such as engine-out capability.
For Starship’s architecture, the practical effects are large. Greater liftoff thrust supports heavier vehicles, larger propellant loads, and higher payloads to low Earth orbit, figures SpaceX has targeted in the 100-plus-ton reusable range. That capacity underpins orbital refueling, lunar missions, and eventual Mars cargo and crew flights.
Continued growth in sea-level thrust therefore tightens the gap between theoretical rocket performance and the high flight rates and reusability needed to make large-scale space transport practical.

Tesla Assisted Driving expands to tenth EU country
Tesla has expanded its Tesla Assisted Driving (TAD) suite to its tenth European country, as Latvia joined a growing list of European Union member states authorizing the company’s advanced driver assistance technology.
Tesla Europe announced this morning that the system is now approved in Latvia, with a software rollout to begin soon.
The approval and rollout follow recognition of a provisional European type approval originally granted by the Netherlands’ RDW authority on April 10.
🚨 Latvia has just received approval for Tesla Full Self-Driving (Supervised)
This is the 10th country in the EU to gain approval:
1. Netherlands — 10 April 2026 (original RDW approval)
2. Lithuania — 20 May 2026
3. Estonia — 29 May 2026
4. Denmark — 9 June 2026
5. Belgium — 10 June 2026
6. Slovenia — 7 September 2026
7. Czechia — 21 September 2026
8. Croatia — 29 September 2026
9. Slovakia — 16 October 2026— TESLARATI (@Teslarati) October 26, 2026
Latvia’s Road Traffic Safety Directorate (CSDD) evaluated the Dutch documentation, coordinated with the other national authorities, and reviewed updates from Tesla. These included tightened limits on speed offsets, automatic resets of any manual speed adjustments after each trip, and stronger driver monitoring.
In Europe, the feature is marketed as Tesla Assisted Driving after a recent rule change that labeled the name “Full Self-Driving” as misleading.
The system remains an SAE Level 2 driver assistance tool, not unsupervised autonomy. It can control speed, steering, braking, lane changes, and intersections while following a navigation route. Drivers need not keep their hands on the wheel at all times, yet they must continuously monitor the road and be prepared to intervene immediately.
The sequence of EU recognitions began with the Netherlands in April and continued through Lithuania, Estonia, Denmark, Belgium, Slovenia, Czechia, Croatia, and Slovakia. Most have relied on mutual recognition of the single Dutch provisional approval rather than independent national testing.
These national clearances do not yet constitute bloc-wide authorization. An EU-wide decision requires a qualified majority in the Technical Committee on Motor Vehicles: at least 15 of 27 member states representing 65 percent of the EU population. Larger markets, like Germany, France, and Italy, remain under review, and a vote is expected this December.
However, for Latvian Tesla owners with compatible vehicles and software, the imminent rollout expands access to the supervised system while underscoring that attentive human oversight remains essential.

Tesla expands Robotaxi geofence in Houston with an ode to SpaceX merger
Tesla expanded its Robotaxi geofence in Houston, Texas, today, enlarging the service area and drawing a new rocket-shaped boundary across the city’s northwestern and central parts.
Although CEO Elon Musk said it was just a coincidence, the expansion seems to be an ode to SpaceX and its potential merger with Tesla.
🚨 Tesla has just expanded its Robotaxi geofence in Houston
It looks a lot like a rocket — we all remember the shape in Austin 🤣 https://t.co/cFOPEuiJ4u
— TESLARATI (@Teslarati) October 26, 2026
The official Tesla Robotaxi account announced the change with the lines “Houston, we have liftoff” and “Bigger service area now live,” pairing them with a map overlay.
The prior white geofence, roughly 25 square miles covering Jersey Village, Harvest Bend, and the Willowbrook corridor along U.S. 290 and State Highway 249, now sits inside a larger blue zone that stretches southeast toward Bellair and closer to central Houston.
Houston’s Robotaxi service launched on April 18, 2026, the same day as Dallas, as Tesla’s first unsupervised public expansion beyond Austin. From the start, the vehicles were Model Ys running without anyone in the front seats, booked through the dedicated Tesla Robotaxi app and open to the public inside the geofence.
Trackers measured the initial zone at about 25 square miles; by late September it had not grown substantially. Community and registry data indicated a modest local fleet of unsupervised Model Ys, while dozens to nearly 200 Cybercabs, the purpose-built, steering-wheel-free two-seaters, have been spotted staging and testing in Houston lots, though public Cybercab rides remain limited to Austin for now.
Across the broader Robotaxi program, Tesla began public Robotaxi rides in Austin in June 2025, as a small geofence and vehicles with safety monitors became available for a ride-hailing service. Later on, Tesla removed the monitors and steadily expanded the service area until it covered most of the Austin metro area.
Unsupervised Robotaxi services now run in six cities: Austin, Dallas, Houston, Miami, Orlando, and Tampa. Cumulative driverless miles reported by the company have reached several million. The Cybercab entered public service in Austin in early September 2026 and has scaled rapidly there. The company has also said that Dallas is next for Cybercab rides in November, with further cities and 24/7 hours targeted by year-end, plus fleet-operator sales of the vehicle.
Waymo also operates a fully driverless service in Houston, which has been open to the public since August of this year.
The Houston expansion continues Tesla’s pattern of starting with tightly controlled validation zones before widening coverage as real-world data accumulates, while the rocket motif on the map underscores the company’s habit of injecting visual flair into its autonomy rollout.
Riders inside the new boundary can request unsupervised Model Y trips in the Robotaxi app; exact operating hours and further Cybercab availability remain subject to app updates and company statements.
