Tesla’s Referral Program will officially come to an end on February 1
Tesla CEO Elon Musk has confirmed that the company’s customer referral program will be coming to an end on February 1st.
After a near 4-year run, Tesla’s widely popular referral program, which turned existing customers into hungry sales machines that were fueled by the lure of winning anything from a $250,000 next-generation Roadster (or two), to the promise of sending a laser-etched photo into deep space aboard a SpaceX rocket, will be shutting its doors for good. While this isn’t the first, second, or third time that the California electric carmaker and its CEO has leveraged the referral program to instill FOMO and convert would-be buyers into customers before a seemingly moving deadline, Musk’s statement that “the whole referral incentive system will end” does sound definitive.

Existing Tesla customers that refer a friend to purchase a Model S, Model X, Model 3 vehicle, or a Tesla Solar Panel system, will have until the end of January 2019 to complete a referral sale. Buyers of a new Tesla will receive six months of Free Supercharging and an additional three months if taking delivery of the car without a test drive. Solar customers that make a purchase through a Tesla referral code will be given a 5-year extended warranty on their system.
What started as a test program in July of 2015 for a young car company that was looking to stimulate cost-effective word-of-mouth sales, in lieu of establishing expensive brick and mortar stores, has become arguably one of Tesla’s most successful sales tools to date.
“Word of mouth has always been a major part of how Tesla sales have grown. When I meet Tesla owners, one of the first things they often tell me is how they have convinced many others to buy the car. As you may already know, Tesla does not advertise or pay for endorsements or product placement. Maybe by doing so we could sell more cars, but I don’t like the idea of trying to trick people into buying a product by false association.” said Musk in an email sent to Model S customers in 2015.
“Reaching potential customers are important, but, if we can amplify word of mouth, then we don’t need to open as many new stores in the future. So, we are going to try an experiment.”
Inasmuch as the closing of the customer incentive program leaves a void to the hundreds of thousands that have grown accustomed to seeing, sharing or using a Tesla referral code, it’s the penning of a new chapter. One that continues the story of how one company accelerated the world’s transition to sustainable energy.
For prosperity’s sake, here’s a look back at the email that started it all.

Word of mouth has always been a major part of how Tesla sales have grown. When I meet Tesla owners, one of the first things they often tell me is how they have convinced many others to buy the car. As you may already know, Tesla does not advertise or pay for endorsements or product placement. Maybe by doing so we could sell more cars, but I don’t like the idea of trying to trick people into buying a product by false association. If you see somebody famous driving a Model S, it is because they genuinely like the car.
If you see it in a movie or TV show, it is because the people associated with that production genuinely like the car. Besides word of mouth, another way that our cars are sold is through stores. These will always be important to allow people to check out new models and ask our product specialists detailed questions. However, stores are quite expensive to set up and operate. In reviewing the Tesla cost of sales, we found that it is approximately $2,000 to sell a car through our stores, higher in some regions and lower in others.
Both ways of reaching potential customers are important, but, if we can amplify word of mouth, then we don’t need to open as many new stores in the future. So, we are going to try an experiment. This is similar to the customer growth program that I worked on at PayPal/X.com back in ’99. What worked for PayPal may not work for Tesla, but it is worth trying, as the net result would be lowering our costs by $2,000, allowing us to give that money to our customers.
From now through October 31st, if someone buys a new Model S through your link, they will get $1,000 off the purchase price and you will get a $1,000 credit in your Tesla account, which can be applied to a future car purchase, service charge or accessories. To put some limits on the experiment, each Tesla owner can grant a maximum of ten $1,000 discounts.
Just for fun, there will also be some things that money can’t buy. If five of your friends order a Model S, you and a guest will receive an invitation to tour the Gigafactory in Nevada – the world’s biggest factory by footprint – and attend the grand opening party. This will be awesome. At ten orders, you get the right to purchase a Founder Series Model X, which is not available to the public, with all options free (value of about $25,000). The first person to reach ten will get the entire car for free.

Tesla is continuing to push the boundaries of vehicle dynamics, as its latest published patent, US12654505B2, or “Suspension Actuator System for a Vehicle,’ which has finally been pushed through.
The design, which is credited to inventors Brian Lee Doorlag, Avraham Kagan, and Justin Sill, introduces a sophisticated hybrid suspension design that blends active motor-driven control with strategic passive elements to deliver superior ride quality, energy efficiency, and resilience against road imperfections, especially potholes.
Suspension Actuator System for a Vehicle@Tesla‘s US20240383297A1 patent introduces an innovative suspension actuator system that transforms vehicle suspension control through an intelligent combination of active and passive control elements.

At the heart of the system is an active control element powered by an electric motor. This motor drives a belt connected to a ball nut assembly and threaded screw, which adjusts the effective length of the suspension strut in real time.
By extending or retracting, the actuator can lift or lower the wheel more accurately, which can end up countering road disturbances. Sensors, including accelerometers and wheel position monitors, feed data to a suspension control system that processes inputs and commands the motor instantly.
This active component doesn’t work alone. A low-rate air spring mounts in parallel with the actuator. Its primary role is to offset much of the vehicle’s static weight, dramatically reducing the power demand on the motor.
Without this, the active system would constantly fight gravity, draining energy and generating heat. The air spring handles steady-state loads efficiently, allowing the motor to focus on dynamic adjustments.
Complementing this is a series of passive control elements—a spring and an adaptive damper—placed between the actuator and the wheel. This setup filters high-frequency vibrations before they reach the active motor, preventing it from overworking on minor inputs. The adaptive damper, potentially magnetorheological or valve-controlled, further tunes damping electronically for optimal comfort and stability.
How It Differs from Traditional Suspensions
Traditional passive suspensions compromise between comfort and handling, while pure active systems can be power-hungry and complex. Tesla’s hybrid approach resolves this by delegating tasks: the parallel air spring manages weight and low-frequency body motions, the series elements absorb rapid vibrations, and the active actuator tackles larger, lower-frequency events.
The result is a smoother, more isolated cabin experience. High-frequency road noise and harshness diminish, while the vehicle maintains precise control during cornering or acceleration. Energy efficiency improves, too—lower motor loads mean reduced battery drain, potentially extending range in electric vehicles.
How It Mitigates Potholes Specifically
Potholes are a major challenge because they provide a sudden drop to the wheel plunge, jarring the body of the vehicle, risking damage. The patent explicitly addresses this. Upon detecting a pothole (via sensors or predictive mapping), the control system activates
the motor to retract the strut, effectively pulling the wheel upward to minimize downward excursion. The series spring/damper cushions the impact, while the parallel air spring maintains overall support.
This proactive “wheel retraction” prevents sharp jolts, preserving passenger comfort and protecting components. Integrated with Tesla’s road roughness mapping patents, the system could anticipate potholes from fleet data, enabling preemptive adjustments for even smoother navigation.
Future Implications for Tesla Vehicles
This technology builds on Tesla’s existing adaptive dampers and air suspension that is seen in Cybertruck, but advances toward fully active control. It could roll out to future models, including refreshed Cybertrucks or next-gen vehicles, enhancing both daily drivability and off-road capability. By minimizing power use and complexity, it aligns with Tesla’s goals of efficiency and scalability.
In summary, US12654505B2 exemplifies Tesla’s engineering philosophy: intelligent integration over brute force. This hybrid suspension promises quieter, more comfortable rides and robust pothole defense, potentially setting a new standard for automotive comfort. As Tesla iterates, drivers can look forward to roads feeling far less rough.
The Tesla Cybercab got a huge nod of support from a Texas Department of Transportation official, who said the all-electric ride-hailing vehicle is “a tangible example of how quickly our transportation system is evolving.”
The Cybercab was present at the Texas Department of Transportation’s Texas Innovation Invitational, an event held each year that allows innovative companies to showcase advancements in transportation.
Tesla Cybercab specs revealed: range, curb weight, range ratings, and more
Marc Williams, the Texas Department of Transportation’s Executive Director, sat in a Cybercab and shared his thoughts in an extensive post on LinkedIn.
Williams’s comments show how Tesla, with its Cybercab, is leading the charge of passenger travel and how it’s changing so rapidly. He notes the absence of traditional driving controls as a telltale sign that the Cybercab is a catalyst for major automotive change, taking controls from drivers and turning them into full-time passengers.
“Observing this vehicle firsthand–from its design and butterfly doors to the cargo trunk configuration–provides a tangible example of how quickly our transportation system is evolving. Sitting inside the cabin, the complete absence of traditional driver controls underscores a significant shift in mobility and vehicle design. No steering wheel, no accelerator, no brake. Only a single touchscreen monitor.”
Tesla has had a great relationship with the State of Texas, especially with its Robotaxi ambitions. Currently, Texas has Tesla Robotaxi operating in multiple cities: Dallas, Austin, San Antonio, and Houston. The company’s main manufacturing plant is also located just outside Austin, and Tesla moved its headquarters to the state several years ago.

The Cybercab is a purpose-built, fully autonomous, two-passenger Robotaxi vehicle designed specifically for ride-hailing services. Tesla has said for years it would be built without a steering wheel or pedals present, although there is still quite a bit of debate among the community regarding that potential.
Earlier this week, we received official word that the EPA had provided the Cybercab with a Certificate of Conformity, giving Tesla permission to enter the vehicle into the chain of public commerce. It is officially ready for roads.
The big question for Tesla remains: Can it solve self-driving before the steering-wheel-less Cybercab officially enters production?

The Boring Company just doubled its tunneling power in Nashville
The Boring Company’s Prufrock MB2 is commissioned and ready to mine beneath Nashville’s streets.
The Boring Company’s second tunnel boring machine, Prufrock MB2, is officially ready to dig in Nashville. The company confirmed the news on X, posting: “Prufrock-MB2 is ready to mine in Nashville! MB2 commissioning is complete, including the brief 11 rpm rotation shown here. Will MB2 catch up to MB1, who had quite the head start? And Prufrock-MB3 ships in August!”
MB2 arrives with meaningful improvements over its predecessor. Lessons learned from the launch and operation of MB1 have already been applied to MB2 to improve efficiency and prepare the machine for launch.
Traditional tunnel boring machines operate in a stop-and-go cycle, digging roughly five feet, halt, erect precast concrete segments to line the tunnel wall, then resume. That repeated interruption is one of the main reasons conventional tunneling is slow and expensive. Prufrock is designed to install the tunnel liner simultaneously with mining, eliminating the need to stop every five feet. The machine also skips the need for excavated launch pits. Prufrock arrives on a truck, tilts down, and launches into the ground within 24 hours. And when the tunnel is complete, it emerges from the ground and drives to its next launch site on a trailer, eliminating the need for expensive cranes or pit excavation. The machine is also fully electric and runs with zero people in the tunnel during normal operations, controlled remotely from a surface operations center.

It won’t be long before we hear of another major update on The Boring Company’s Music City Loop project – a planned underground transit network beneath Nashville that would move passengers in electric vehicles through a series of tunnels at highway speeds, and bypassing surface traffic entirely. Nashville was selected in part because of its strong rock conditions that suits the Prufrock machines well, and relatively less regulatory hurdles.
Progress has been steady on multiple fronts. All 37 permits and approvals required ahead of tunneling have been obtained, out of 45 total. Key wins include a fully executed TDOT tunnel permit authorizing 25 miles of tunnel, unanimous airport authority approval for a Nashville International Airport station, and the city’s first residential station agreement serving downtown tower residents.
With MB1 already tunneling, MB2 now commissioned, and MB3 shipping in August, Nashville is becoming something of a live proving ground for scaled tunnel boring. The broader ambition is not limited to one city. The Boring Company’s stated goal is to make underground transportation a practical alternative to surface roads across major metro areas. Nashville is one of many cities, including a successful Las Vegas tunnel system, where that idea is being put to the test at real speed.
