Tesla engineers share Model 3 steering, drivetrain, and suspension secrets
The Tesla Model 3 is practically taking over the electric car market, establishing a strong presence in every region where it is released. A key reason behind this lies in the fact that the Model 3 happens to be a really fine automobile that just happens to be electric. It’s quick on its feet, handles nimbly despite its weight, and it provides a ride that is both sporty and comfortable.
One of the UK’s most established motoring magazines, Autocar, spoke with a number of Tesla engineers to gain some insights on the design and development process of the Model 3. The result was an extensive discussion in how a clean-sheet design and a serious commitment to safety could make all the difference when creating a car that is, for all intents and purposes, intended to reinvent the automobile.
Tires
Immediately emphasized by the Tesla engineers was that the Model 3’s chassis and suspension were designed using a ‘first principles’ clean-sheet approach. This started with the Model 3’s tires, which the engineers fondly described as the “unsung heroes” of the vehicle, being critical to its feel and drivability. The development of the Model 3’s tires began back in 2015, when Tesla started working with manufacturers to create the ideal tires for the electric sedan.
The engineers noted that the tires of a high-performance electric car like the Model 3 are challenged in different ways compared to gas-powered automobiles. This is due to a number of factors, including the vehicle’s weight and its instant torque. Since the bulk of an EV’s mass is situated lower down compared to a vehicle with an internal combustion engine, there is less vertical force buildup on the outside pair of tires to generate grip when cornering.
To address this, Tesla focused on tread stiffness, even developing new compounds to deliver a good combination of cornering grip and low rolling resistance for the Model 3’s tires. Sound-absorbing foam placed inside the tire cavity further increases comfort during driving by suppressing noise. The Model 3’s rear wheels hold some interesting secrets as well. The engineers revealed that each rear wheel of the electric sedan has six degrees of freedom, with five links and one damper, though the links are split to allow superior control over forces that are transmitted through the vehicle’s tire contact patch.
Safety Systems and Steering
The Model 3 has earned a perfect 5-Star Safety Rating from the NHTSA, the Euro-NCAP, and the ANCAP. This comes as no surprise, considering that the vehicle is designed from the ground up to emphasize safety. The Model 3’s front suspension, for example, was specifically designed to provide maximum protection in small-overlap frontal collision crash tests.
Sacrificial links that are designed to snap when the front wheel and suspension get damaged are also integrated into the vehicle, allowing the Model 3’s front wheels to rotate. This moves the front wheels outside the Model 3’s body, while pushing the car, its occupants, and its battery pack from the point of impact. These safety systems extend to the Model 3’s dual-motor AWD variants as well.
Tesla designed the Model 3’s electric power steering system to have a rapid 10:1 ratio. The power steering is equipped with full redundancy with separate power feeds taken directly from the vehicle’s high-voltage battery. The engineers also mentioned two electronic modules and two inverters providing “hot backup” to the system if one fails.
Brakes
The Model 3’s braking system is quite unique, in the way that Tesla opted to equip the electric sedan with more expensive four-pot brake calipers at the front wheels instead of a single-piston sliding mechanism. This gives the Model 3 superior pedal response, and it opened the door for the electric car maker to design its own piston seals that fully retract the brake pads after braking; thus, boosting available driving range and cutting drag. Such a system adds to the Model 3’s efficiency, which has proven superior to other premium electric vehicles like the Audi e-tron and the Jaguar I-PACE.
Elon Musk has mentioned multiple times in the past that brake pads in a Tesla will last for the lifetime of a vehicle. This is no exaggeration, according to the Tesla engineers, who noted that the Model 3’s discs and brake pads are designed to last for around 150,000 miles. This is made possible by the Model 3’s regenerative braking system, which allows drivers to slow down the vehicle without using its physical brakes. As for rust issues, the engineers pointed out that Tesla has developed new anti-corrosion techniques for its electric cars.
Suspension
Perhaps the most interesting tidbit discussed by the Tesla engineers involved the Model 3’s suspension. In true Elon Musk fashion, Tesla actually used concepts from NASA when it was refining the suspension settings of the electric sedan. The electric car maker based the Model 3’s suspension settings on a study by the space agency about how long the human body can be subjected to a certain frequency without feeling uncomfortable. Considering that the vertical frequency of a suspension’s movement affects comfort and drivability, Tesla engineers settled on a vertical frequency that is equivalent to a brisk walk or a slow run to give the Model 3’s chassis a comfortable, sporty feel.
The Model 3’s suspension has impressed a number of industry experts, among them being automotive veteran and teardown expert Sandy Munro of Munro and Associates. During his teardown of the vehicle, Munro noted that the Model 3 has areas of improvement in its body and finish, but everything from the electric car’s suspension, all the way down to its tires, is flawless. In a segment on YouTube’s Autoline TV, Munro mentioned that the person who tuned the Model 3’s suspension could easily be an “F1 Prince.”
During the electric car maker’s second-quarter earnings call, Elon Musk mentioned that the “story for Tesla’s future is fundamentally Model 3 and Model Y.” While the Model S and Model X were made to prove that electric vehicles could be superior alternatives to gas-powered premium sedans and SUVs, the more affordable Model 3 — and in extension, the Model Y — would likely be the cars that could reinvent the automobile and encourage mass-market car buyers to rethink what a vehicle could be like. Based on the Model 3’s success so far, it appears that Tesla is so far succeeding in this endeavor.

Tesla Cybertruck gets long-awaited safety feature
Tesla has announced the rollout of its innovative anti-dooring protection feature to the Cybertruck via the 2026.8 software update.
Tesla is rolling out a new and long-awaited feature to the Cybertruck all-electric pickup, and it is a safety addition geared toward pedestrian and cyclist safety, as well as accidents with other vehicles.
Tesla has announced the rollout of its innovative anti-dooring protection feature to the Cybertruck via the 2026.8 software update.
This safety enhancement uses the vehicle’s existing cameras to detect approaching cyclists, pedestrians, or vehicles in the blind spot while parked. Upon attempting to open a door, if a hazard is detected, the system activates: the blind spot indicator light flashes, an audible chime sounds, and the door will not open on the initial button press.
Drivers must wait briefly and press the button again to override, providing crucial seconds to avoid an accident.
Anti-dooring protection now rolling out to @Cybertruck
This feature comes standard on every new Model 3, Model Y & Cybertruck – using cameras to delay door opening if a cyclist, pedestrian or other vehicle is detected approaching in your blind spot
— Tesla North America (@tesla_na) March 17, 2026
The feature, also known as Blind Spot Warning While Parked, comes standard on every new Model 3 and Model Y, and is now extending to the Cybertruck. Leveraging Tesla’s vision-based system without requiring new hardware, it represents a cost-effective software solution that builds on community suggestions dating back to 2018.
This technology addresses the persistent danger of “dooring,” where a driver opens a car door into the path of a passing cyclist or pedestrian.
Tesla implemented this little-known feature to make its cars even safer
Dooring incidents are alarmingly common in urban environments.
According to Chicago data, in 2011 alone, there were 344 reported dooring crashes, accounting for approximately 20 percent of all bicycle crashes in the city, nearly one incident per day.
While numbers have fluctuated (dropping to 11 percent in 2014 before rising again), dooring consistently represents 10-20 percent of bike-related crashes in major cities.
A national analysis of emergency department data estimates over 17,000 dooring-related injuries treated in the U.S. over a decade, with many involving fractures, contusions, and head trauma, particularly affecting upper extremities.
By automatically intervening, Tesla’s system not only protects vulnerable road users but also safeguards its owners from potential liability and enhances overall road safety.
As cities promote cycling for sustainable transport, features like this demonstrate how advanced driver assistance and camera systems can evolve beyond highway driving to everyday urban scenarios.
Enthusiastic responses on social media highlight appreciation for the proactive safety measure, with some calling for broader rollout to older models where hardware permits. Tesla continues to push the boundaries of vehicle safety through over-the-air updates, making its fleet smarter and safer over time.

Tesla Roadster is ‘sorcery and magic’ and might be worth the wait, Uber founder says
Perhaps the wait will be worth it, especially according to Uber founder Travis Kalanick, who recently teased the Roadster’s potential capabilities based on what he has heard from internal Tesla sources.
Tesla is planning to unveil the Roadster in late April after years of waiting. But the wait might be worth it, according to Travis Kalanick, the founder of Uber, who recently shed some light on his expectations for the all-electric supercar.
We all know the Roadster is supposed to have some serious capability. CEO Elon Musk has said on numerous occasions that the Roadster will be unlike anything else ever produced. It might go from 0-60 MPH in about a second, it might hover, it might have SpaceX cold gas thrusters.
However, the constant delays in the Roadster program and its unveiling event continue to send Tesla fans into confusion because they’re just not sure when, or if, they’ll ever see the finished product.
Perhaps the wait will be worth it, especially according to Uber founder Travis Kalanick, who recently teased the Roadster’s potential capabilities based on what he has heard from internal Tesla sources.
Kalanick said on X:
When I’ve run into people who are in the know, I inquire, they tell me nothing, but their eyebrows raise and their eyes widen in a way that can only mean something of sorcery and magic is coming…

Musk has said this vehicle is not going to be geared for safety, and that, “If safety is your number one goal, do not buy the Roadster.”
There has been so much hype regarding the Roadster that it is hard to believe the company could not come through on some kind of crazy features for the vehicle.
However, the latest delay that Tesla put on the unveiling event is definitely eye-opening, especially considering it is the latest in a series of pushbacks the company has put on the vehicle for the past several years.
Tesla has made several jumps in the Roadster project over the past few months, as it has ramped up hiring for the vehicle and also applied for a patent for a new seat design.
The car has been a back-burner project for Tesla, as it has been focusing primarily on autonomy and the rollout of Robotaxi and Cybercab. Additionally, its other vehicle projects, like the Model 3 and Model Y refreshes, took precedence.
Tesla still plans to unveil the Roadster next month, so we can hope the company can stick to this timeframe.

Elon Musk clarifies viral Tesla Cybertruck accident with driver logs
Musk has come out to say that the driver logs have already shown that the driver “disengaged Autopilot four seconds before crashing,” in a post on X.
Tesla CEO Elon Musk has clarified some details regarding the viral Tesla Cybertruck accident with company driver logs, which show various metrics at the time of an incident.
The logs have been used in the past to pull responsibility off of Tesla when the automaker’s Full Self-Driving (Supervised) or Autopilot platforms are blamed for a collision or accident. It appears this will be no different.
On Tuesday, a video of a Cybertruck crashing into an overpass barrier in August 2025 was shared by Fox Business in a story that reported a woman was suing the automaker for $1 million in a liability and negligence case.
In the suit, Justine Saint Amour said that, “Something terrifying happened, without warning, the vehicle attempted to drive straight off an overpass.” Her attorney, Bob Hilliard, said Amour “tried to take control, but crashed into the barrier and was seriously injured (mostly her shoulder, neck, and back).”
The Tesla Model Y is leading China’s electric SUV segment by a wide margin
Tesla vehicle crashes are widely popular to report by mainstream media outlets because of the sensationalism of the event. Oftentimes, these outlets will include Tesla in the headline, especially because it will pique the interest of the masses, as most who read the story are waiting to see the claim that Autopilot or Full Self-Driving was the culprit of the accident.
However, Tesla has access to the logs of every vehicle in its fleet, which will show the various metrics, like whether either FSD or Autopilot was active, if the accelerator was pressed, the speed, and other important factors.
Musk has come out to say that the driver logs have already shown that the driver “disengaged Autopilot four seconds before crashing,” in a post on X.
Logs show driver disengaged Autopilot four seconds before crashing
— Elon Musk (@elonmusk) March 18, 2026
If the logs do show this, which Tesla will likely have to prove in court, the real question would be why did the Amour disengage the suite?
Tesla’s Full Self-Driving suite is still not fully autonomous, meaning the driver cannot pull attention away from the road and must be ready to take over the vehicle at all times.
It will be interesting to see how this particular case pans out, especially considering the clip that was released by the law firm starts at about four seconds before the collision. Tesla logs have dispelled media reports in the past that have accused the company’s suite of being responsible for an accident, so there will be some major attention on what is proven in this particular case.
