Stealth EV startup Rivian adds McLaren and Nike execs to lead development
Rivian, the stealthy, Michigan-based electric vehicle (EV) startup, is taking large steps forward in their new vehicle development program. The company recently added two new executives, Mark Vinnels and Rob Williams.
Mark Vinnels joined Rivian in November as Executive Director of Engineering and Programs, and oversees the development of Rivian’s vehicle platform. Vinnels was formerly the Executive Director of Product Development and Programme Director at McLaren Automotive. Vinnels joined McLaren in 2004 to lead the development of McLaren’s first road car since the infamous F1. Before joining McLaren, Vinnels was head of Lotus’s new vehicle programs and oversaw the Elise, Exige, and Europa new vehicle lines. Vinnels is also credited for his instrumental role in the development of GM’s Family 1 engine program.

While at McLaren, Vinnels helped the company grow its engineering division from roughly 50 engineers to 550 and significantly increased its vehicle lineup.
Rivian’s team also includes another former McLaren executive, Anthony Sheriff, who joined Rivian’s Board of Directors in 2016. Sheriff was the Managing Director of McLaren Automotive from 2003-2013, a period in which McLaren created a road car division in addition to the company’s rich history in the automotive racing arena. Sheriff was an executive at Fiat before his tenure at McLaren and also sits on the Board of Directors for electric supercar manufacturer Rimac.
Also joining Rivian is Rob Williams as Chief Creative Officer. Williams carries experience from both the automotive industry and the footwear industry. He was most recently a Senior Design Director of Footwear at Nike and spent four-and-a-half years at Chrysler. During his time as a product designer at Chrysler, he led several designs of Chrysler SUVs and Dodge Trucks.
Williams joins Jeff Hammoud, Director of Vehicle Design. Hammoud has extensive experience at Fiat-Chrysler and left the company as Chief of Design of the Jeep Brand. Hammoud joined Rivian in May 2017, followed by Williams in June.
Based on a combination of the design team’s backgrounds and patents released by Rivian last summer, it appears that Rivian’s first vehicle could be some sort of SUV. An in-depth analysis of Rivian’s design team members’ LinkedIn profiles reveals that nearly half of the team has experience with Fiat Chrysler Automotive (Formerly Chrysler), with many specializing in SUV/Truck designs.

Rivian currently has 225 employees, up from 115 at the start of the year. Other notable additions to Rivian’s team include 15 former Faraday Future employees. Faraday Future is nearly defunct after it continued to miss its wildly ambitious goals and saw its main financier’s global expansion fall apart. Most of the team from Faraday is working on Rivian’s autonomous driving technology or other highly technical roles.
The timeline for Rivian’s massive 2.6 million-square-foot manufacturing facility on the west side of Normal is still unknown. Rivian purchased the factory in January 2017 for $16 million, including all of the contents in the factory.
While Rivian hasn’t revealed many details about the development of its all-electric vehicle platform, the company revealed today that it has received a large strategic investment from New York-based Sumitomo Corporation of Americas (SCOA).
Rivian’s CEO RJ Scaringe couldn’t comment directly on the details of the investment, but did say the following to AdaptBN: “We are honored and excited to have Sumitomo as a strategic investor. Their global reach, expertise, and network in the automotive sector will help us in executing our vision. This investment reflects the result of our team’s hard work in developing our technology and products.”
Due to the level of mystery surrounding Rivian’s plans and product line, local residents and officials have begun comparing it to the likes of “Willy Wonka’s Chocolate Factory.” But only time will tell if Rivian holds a golden ticket to the future.

Tesla is improving Giga Berlin’s free “Giga Train” service for employees
With this initiative, Tesla aims to boost the number of Gigafactory Berlin employees commuting by rail while keeping the shuttle free for all riders.
Tesla will expand its factory shuttle service in Germany beginning January 4, adding direct rail trips from Berlin Ostbahnhof to Giga Berlin-Brandenburg in Grünheide.
With this initiative, Tesla aims to boost the number of Gigafactory Berlin employees commuting by rail while keeping the shuttle free for all riders.
New shuttle route
As noted in a report from rbb24, the updated service, which will start January 4, will run between the Berlin Ostbahnhof East Station and the Erkner Station at the Gigafactory Berlin complex. Tesla stated that the timetable mirrors shift changes for the facility’s employees, and similar to before, the service will be completely free. The train will offer six direct trips per day as well.
“The service includes six daily trips, which also cover our shift times. The trains will run between Berlin Ostbahnhof (with a stop at Ostkreuz) and Erkner station to the Gigafactory,” Tesla Germany stated.
Even with construction continuing at Fangschleuse and Köpenick stations, the company said the route has been optimized to maintain a predictable 35-minute travel time. The update follows earlier phases of Tesla’s “Giga Train” program, which initially connected Erkner to the factory grounds before expanding to Berlin-Lichtenberg.
Tesla pushes for majority rail commuting
Tesla began production at Grünheide in March 2022, and the factory’s workforce has since grown to around 11,500 employees, with an estimated 60% commuting from Berlin. The facility produces the Model Y, Tesla’s best-selling vehicle, for both Germany and other territories.
The company has repeatedly emphasized its goal of having more than half its staff use public transportation rather than cars, positioning the shuttle as a key part of that initiative. In keeping with the factory’s sustainability focus, Tesla continues to allow even non-employees to ride the shuttle free of charge, making it a broader mobility option for the area.

Tesla Model 3 and Model Y dominate China’s real-world efficiency tests
The Tesla Model 3 posted 20.8 kWh/100 km while the Model Y followed closely at 21.8 kWh/100 km.
Tesla’s Model 3 and Model Y once again led the field in a new real-world energy-consumption test conducted by China’s Autohome, outperforming numerous rival electric vehicles in controlled conditions.
The results, which placed both Teslas in the top two spots, prompted Xiaomi CEO Lei Jun to acknowledge Tesla’s efficiency advantage while noting that his company’s vehicles will continue refining its own models to close the gap.
Tesla secures top efficiency results
Autohome’s evaluation placed all vehicles under identical conditions, such as a full 375-kg load, cabin temperature fixed at 24°C on automatic climate control, and a steady cruising speed of 120 km/h. In this environment, the Tesla Model 3 posted 20.8 kWh/100 km while the Model Y followed closely at 21.8 kWh/100 km, as noted in a Sina News report.
These figures positioned Tesla’s vehicles firmly at the top of the ranking and highlighted their continued leadership in long-range efficiency. The test also highlighted how drivetrain optimization, software management, and aerodynamic profiles remain key differentiators in high-speed, cold-weather scenarios where many electric cars struggle to maintain low consumption.

Xiaomi’s Lei Jun pledges to continue learning from Tesla
Following the results, Xiaomi CEO Lei Jun noted that the Xiaomi SU7 actually performed well overall but naturally consumed more energy due to its larger C-segment footprint and higher specification. He reiterated that factors such as size and weight contributed to the difference in real-world consumption compared to Tesla. Still, the executive noted that Xiaomi will continue to learn from the veteran EV maker.
“The Xiaomi SU7’s energy consumption performance is also very good; you can take a closer look. The fact that its test results are weaker than Tesla’s is partly due to objective reasons: the Xiaomi SU7 is a C-segment car, larger and with higher specifications, making it heavier and naturally increasing energy consumption. Of course, we will continue to learn from Tesla and further optimize its energy consumption performance!” Lei Jun wrote in a post on Weibo.
Lei Jun has repeatedly described Tesla as the global benchmark for EV efficiency, previously stating that Xiaomi may require three to five years to match its leadership. He has also been very supportive of FSD, even testing the system in the United States.

Elon Musk reveals what will make Optimus’ ridiculous production targets feasible
Musk recent post suggests that Tesla has a plan to attain Optimus’ production goals.
Elon Musk subtly teased Tesla’s strategy to achieve Optimus’ insane production volume targets. The CEO has shared his predictions about Optimus’ volume, and they are so ambitious that one would mistake them for science fiction.
Musk’s recent post on X, however, suggests that Tesla has a plan to attain Optimus’ production goals.
The highest volume product
Elon Musk has been pretty clear about the idea of Optimus being Tesla’s highest-volume product. During the Tesla 2025 Annual Shareholder Meeting, Musk stated that the humanoid robot will see “the fastest production ramp of any product of any large complex manufactured product ever,” starting with a one-million-per-year line at the Fremont Factory.
Following this, Musk stated that Giga Texas will receive a 10 million-per-year unit Optimus line. But even at this level, the Optimus ramp is just beginning, as the production of the humanoid robot will only accelerate from there. At some point, the CEO stated that a Mars location could even have a 100 million-unit-per-year production line, resulting in up to a billion Optimus robots being produced per year.
Self-replication is key
During the weekend, Musk posted a short message that hinted at Tesla’s Optimus strategy. “Optimus will be the Von Neumann probe,” the CEO wrote in his post. This short comment suggests that Tesla will not be relying on traditional production systems to make Optimus. The company probably won’t even hire humans to produce the humanoid robot at one point. Instead, Optimus robots could simply produce other Optimus robots, allowing them to self-replicate.
The Von Neumann is a hypothetical self-replicating spacecraft proposed by the mathematician and physicist John von Neumann in the 1940s–1950s. The hypothetical machine in the concept would be able to travel to a new star system or location, land, mine, and extract raw materials from planets, asteroids, and moons as needed, use those materials to manufacture copies of itself, and launch the new copies toward other star systems.
If Optimus could pull off this ambitious target, the humanoid robot would indeed be the highest volume product ever created. It could, as Musk predicted, really change the world.
