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.

Did Tesla make the perfect car for families? Tesla Model Y L Full Review
Last week, Tesla sent me the Model Y L for five days to test, assess, and enjoy for journalistic purposes. It’s always a treat when I get any media vehicle, and I’ve had the pleasure of working with Tesla and Ford for hands-on reviews of their products.
This one was exceptionally exciting for a few reasons: first, because it is the car I own, but bigger, so I was really excited to see if that extra space was worth it; and second, because my Fiancée (we’re down to just 18 days ’til she’s officially my wife!!!) and I plan to fill a car up with kids in the near future, so it was really nice to have a trial with a car that would potentially be in our driveway in a few years.
I did a full 10-minute video review of the Model Y L, which I will post at the bottom of this more condensed written version. If you prefer to watch a review, go ahead and skip to the bottom for that.
For those who prefer the writing, I’ll break down the big things about the Model Y L that I noticed, focusing on the big addition/difference that this car has from the Model Y: the third row. Tesla also added small-but-mighty changes to the Y L that I really wish were on my Model Y Premium, so I’ll be sure to mention those as well.
What Makes It Different from the Model Y?

The first thing to note is that the interior of this vehicle, from the front row, is generally the same. It truly does feel like you’re in the same exact car with a slightly different seating layout. Of course, Tesla interiors do feel this way, at least with the Model 3 and Model Y, but there are no drastic differences between the Model Y L and the Model Y from the front row.
This should be expected, so definitely do not go into it thinking you’ll know you’re in a different car. It is a very similar experience to the Model Y.
Tesla Model Y L: new features that make it better than the standard Model Y
The true differences come from the back two rows. The only true difference from the front is the addition of a new Dynamics Feature that falls under the “Ride & Handling Priority” menu, which now allows you to adjust the suspension damping to prioritize a comfortable ride for everyone or one that is noticeably better from the rear two rows. In terms of ride comfort, the front rows definitely feel the impact of this; it is a noticeable difference and much stiffer in the driver’s seat with this setting turned to prioritize the rear occupants.
What changes from an engineering standpoint between these two settings @elonmusk @larsmoravy?

There are also a series of small improvements, like the rear taillight is now up toward the spoiler, which must be a strategy for making the rear glass actually useful in the Y L compared to the regular Y.
Pretty crazy how much different the rear windshield is compared to the Model Y

Some other small changes are the addition of small magnets for the sub-trunk lid, which is a great addition and something I’d like to do in my Model Y; it sounds to me as if the Model Y L liftgate motor is less whiny than the one in my Model Y; and all three rows of climate are controllable from the front touchscreen.
I talk about them in a short video here:

Second and Third-Row Legroom
The major feature of the Model Y L is the third row, and Tesla did a great job of making it spacious enough for more than just your nine-year-old nephew. It actually does have a suitable amount of legroom for adults, but it is dependent on how tall the people are in the first- and second-row seats in front of you.
This is where I caught some slack from those who have also sat in the Model Y L and believe there is enough room for anyone of any height. I certainly believe that those who are not complainers could sit back there for a multiple-hour drive and not complain. I would enjoy sitting in the back row because I think it is comfortable; the vents for air are perfectly positioned on the C pillars for maximum comfort, and I found that there was enough room back there for me. I’m 5′ 8″, so I’m definitely not tall. However, I found that I had more than enough legroom:

The picture above is where my Fiancèe could sit comfortably in the second row in front of me, and she is 5′ 1″. There is a lot of give and take with these seats, and I believe most groups could make it work. She was comfortable in the second-row seat in front in this position, and as you can see, I have plenty of room. She could easily come back a few inches, and I’d still be comfortable.
This is where I think people would truly benefit from seeing what the space in this car looks like for themselves. To me, I found it more than suitable for a group of friends to go out in and for everyone to be comfortable. There might be some strategy to it if you have some taller friends, but it’s definitely doable.
Overall, the space in the Y L in the back two rows is great: the second-row Captain’s Chairs have mechanical armrests that go down automatically when you exit the car, and come back up on their own when you return. The second row also has ventilated seats; you’ll only have the heat option in the third row.

Overall Thoughts
It was really a great five days with the Model Y L, and I do believe that this is a great car for families. I do not believe it is the perfect one. It is really an excellent option for those who can make do with what is truly a compact crossover stretched out to make way for a third row. However, I think that more families simply want something large, like Tahoe or Expedition large, and the Model Y L does not necessarily answer that call.
I think it is more than reasonable for a family of six to have this car and make it work. It is safe, it has Full Self-Driving, which I believe will be a non-negotiable for me moving forward in car buying; and it is relatively affordable, with the Launch Edition coming in at a price of $61,990 before options. Not going to a gas station for the past year has really been a lifesaver for me, especially with home charging saving us so much money.
Tesla will need to have an answer for the families that want something like a Cyber SUV or simply something that qualifies as a full-size SUV. I just truly do not think that every family will see this as enough space, and I think that’s understandable. If someone were to want to take an overnight trip with their four kids, I don’t know if it would be the easiest cargo situation because without that third row folded down, that trunk space is confined to just 14.8 cubic feet. I couldn’t take four kids and a wife to Ocean City for a week with using only the trunk space. We’d likely have to get creative, and I think that’s what many families want to avoid.
For comparison’s sake, a Tahoe offers 25.5 cubic feet of trunk space, which is still tight, but much more manageable and forgiving.
With all that being said, the Model Y L is still a great option and I’d be willing to see past the cargo issues because of FSD and the safety of Tesla vehicles overall. For our full review, check out the video below:

Why automakers keep turning down Elon Musk’s Tesla Full Self-Driving offer
Elon Musk confirms no automaker has ever accepted Tesla’s offer to license Full Self-Driving software.
Elon Musk gave a brief answer on X Monday that confirmed that Tesla’s standing offer to license Full Self-Driving to other automakers still has zero takers. Sawyer Merritt wrote that “Tesla has for years openly invited other automakers to license FSD. None of them have accepted,” responding to a prediction from Boom Supersonic founder Blake Scholl that Tesla would eventually open FSD the way it opened its Supercharger network to rival brands. Musk’s reply to Merritt was one word: “Exactly.”
It is not the first time Musk has made this point. He said something similar in November, when he called legacy automakers reluctance to adopt FSD “crazy,” and Tesla has floated the offer publicly since at least 2021. Scholl’s prediction touches on something real. Once NACS became the de facto charging standard, adoption from Ford, GM, Rivian and others followed within about a year. FSD licensing was supposed to work the same way once Tesla built enough of a lead that switching made sense for everyone.

— Sawyer Merritt (@SawyerMerritt) September 22, 2026
The case for licensing now is stronger than it was two years ago. Waymo and Zoox are logging hundreds of thousands of unsupervised autonomous miles, along with Tesla’s own Robotaxi fleet. Every automaker still selling driver assist systems that lag FSD has given the robotaxi conversation to Tesla, Waymo and Zoox by default. Licensing FSD would let a GM or a Ford compete on the same field without spending a decade and billions of dollars building a stack from scratch, the same argument Tesla made when it opened the Supercharger network to bring more EVs onto its chargers.
But FSD is not a connector standard. As one reply to Musk’s post pointed out, licensing FSD is not a software license the way NACS was a plug spec. It requires adopting Tesla’s eight camera layout and its onboard compute architecture, meaning a licensee’s cars would effectively become Tesla hardware wearing someone else’s badge. That is the visible obstacle. The less visible one is data. A licensed FSD stack would report back the same telemetry Tesla collects from its own fleet, giving Tesla a continuous read on how a competitor’s cars are actually driven, where they struggle, and how often drivers intervene. For an automaker trying to build its own autonomy program, or simply trying to keep its build quality and safety record private, handing Tesla that visibility could be a bigger cost than the hardware bill. It is the reason the Supercharger comparison only goes so far. Opening a charging plug cost Tesla very little. Opening FSD would cost a rival something it cannot get back.

Tesla Roadster is available for order once again following brief hold
Tesla has reopened reservations for its long-delayed next-generation Roadster, asking buyers for a $50,000 deposit just days before an October 1 reveal event in Waco, Texas. The move revives a reservation process first launched in 2017 and later paused when Tesla pulled pricing from its website in 2021.
The reservation page requires an immediate $5,000 credit-card payment, described as fully refundable, followed by a $45,000 wire transfer due within 10 days, which is identical to what was expected previously. Reservations are not considered final until the wire clears.
The structure matches the 2017 terms Tesla used when it first collected deposits after unveiling a prototype. Tesla has not published a confirmed retail price or production start date on the order page.

The October 1 event is scheduled in Waco, about 90 minutes north of Tesla’s Austin headquarters and near SpaceX’s McGregor rocket test site. Tesla sent invitations to existing reservation holders and posted a “Go for launch” teaser on September 12.
The Federal Aviation Administration (FAA) established a temporary flight restriction over the McGregor area from September 18 through October 2, consistent with plans for a demonstration involving SpaceX-designed cold-gas thrusters. Elon Musk has previously described the optional package as enabling extreme acceleration or brief hovering. Tesla has said the event will include pricing, specifications, and production targets.
The second-generation Roadster was first shown in November 2017 during Tesla’s Semi launch. Musk promised production in 2020, with claimed performance of 0-60 mph in 1.9 seconds, more than 250 mph top speed, and roughly 620 miles of range.
Those targets have slipped repeatedly.
Tesla later pointed to 2022, 2023, 2024, and 2025-2026 before indicating production would not begin until 2027 or 2028 at Gigafactory Texas. Design work has continued, with reports of a sharper, Cybertruck-influenced look replacing the original curvy prototype.
Original reservation holders who paid $50,000 in 2017, or $250,000 for the Founders Series, have waited nearly nine years without a production car. Some high-profile customers canceled. Tesla’s decision to reopen orders now, after previously shutting them down, tests whether new buyers will commit substantial funds before seeing a finalized production vehicle. The October 1 event is intended to answer remaining questions about what those buyers will actually receive and when.
