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.

Lufthansa Group to equip Starlink on its 850-aircraft fleet
Under the collaboration, Lufthansa Group will install Starlink technology on both its existing fleet and all newly delivered aircraft, as noted by the group in a press release.
Lufthansa Group has announced a partnership with Starlink that will bring high-speed internet connectivity to every aircraft across all its carriers.
This means that aircraft across the group’s brands, from Lufthansa, SWISS, and Austrian Airlines to Brussels Airlines, would be able to enjoy high-speed internet access using the industry-leading satellite internet solution.
Starlink in-flight internet
Under the collaboration, Lufthansa Group will install Starlink technology on both its existing fleet and all newly delivered aircraft, as noted by the group in a press release.
Starlink’s low-Earth orbit satellites are expected to provide significantly higher bandwidth and lower latency than traditional in-flight Wi-Fi, which should enable streaming, online work, and other data-intensive applications for passengers during flights.
Starlink-powered internet is expected to be available on the first commercial flights as early as the second half of 2026. The rollout will continue through the decade, with the entire Lufthansa Group fleet scheduled to be fully equipped with Starlink by 2029. Once complete, no other European airline group will operate more Starlink-connected aircraft.
Free high-speed access
As part of the initiative, Lufthansa Group will offer the new high-speed internet free of charge to all status customers and Travel ID users, regardless of cabin class. Chief Commercial Officer Dieter Vranckx shared his expectations for the program.
“In our anniversary year, in which we are celebrating Lufthansa’s 100th birthday, we have decided to introduce a new high-speed internet solution from Starlink for all our airlines. The Lufthansa Group is taking the next step and setting an essential milestone for the premium travel experience of our customers.
“Connectivity on board plays an important role today, and with Starlink, we are not only investing in the best product on the market, but also in the satisfaction of our passengers,” Vranckx said.

Tesla locks in Elon Musk’s top problem solver as it enters its most ambitious era
The generous equity award was disclosed by the electric vehicle maker in a recent regulatory filing.
Tesla has granted Senior Vice President of Automotive Tom Zhu more than 520,000 stock options, tying a significant portion of his compensation to the company’s long-term performance.
The generous equity award was disclosed by the electric vehicle maker in a recent regulatory filing.
Tesla secures top talent
According to a Form 4 filing with the U.S. Securities and Exchange Commission, Tom Zhu received 520,021 stock options with an exercise price of $435.80 per share. Since the award will not fully vest until March 5, 2031, Zhu must remain at Tesla for more than five years to realize the award’s full benefit.
Considering that Tesla shares are currently trading at around the $445 to $450 per share level, Zhu will really only see gains in his equity award if Tesla’s stock price sees a notable rise over the years, as noted in a Sina Finance report.
Still, even at today’s prices, Zhu’s stock award is already worth over $230 million. If Tesla reaches the market cap targets set forth in Elon Musk’s 2025 CEO Performance Award, Zhu would become a billionaire from this equity award alone.
Tesla’s problem solver
Zhu joined Tesla in April 2014 and initially led the company’s Supercharger rollout in China. Later that year, he assumed the leadership of Tesla’s China business, where he played a central role in Tesla’s localization efforts, including expanding retail and service networks, and later, overseeing the development of Gigafactory Shanghai.
Zhu’s efforts helped transform China into one of Tesla’s most important markets and production hubs. In 2023, Tesla promoted Zhu to Senior Vice President of Automotive, placing him among the company’s core global executives and expanding his influence beyond China. He has since garnered a reputation as the company’s problem solver, being tapped by Elon Musk to help ramp Giga Texas’s vehicle production.
With this in mind, Tesla’s recent filing seems to suggest that the company is locking in its top talent as it enters its newest, most ambitious era to date. As could be seen in the targets of Elon Musk’s 2025 pay package, Tesla is now aiming to be the world’s largest company by market cap, and it is aiming to achieve production levels that are unheard of. Zhu’s talents would definitely be of use in this stage of the company’s growth.

Tesla counters Norway’s VAT hike with dedicated consumer bonus
The move follows Tesla Norway’s stunning finish in 2025, where the company saw substantial sales during the final weeks of the year.
Tesla has rolled out a price incentive in Norway, effectively offsetting a notable VAT increase that hit electric vehicle buyers at the start of 2026.
The move follows Tesla Norway’s stunning finish in 2025, where the company saw substantial sales during the final weeks of the year.
A “Tesla bonus”
Once the VAT increase kicked in at the start of 2026, Tesla Norway’s sales cooled almost immediately, as noted in a CarUp report. Tesla’s response was swift, with the electric vehicle maker rolling out what it calls a “Tesla bonus.”
This bonus effectively cuts prices by up to 50,000 kronor across eight model variants. All versions of the Tesla Model Y qualify for the incentive, along with most Tesla Model 3 trims, save for the base entry-level model.
This means that for Tesla Norway’s best-selling vehicles, the bonus effectively restores pricing to pre-VAT levels. This blunts the impact of the new tax and makes Tesla’s vehicle offerings competitive again in Europe’s most EV-saturated market.
Stabilizing demand
In addition to the “Tesla bonus,” the electric car maker is also offering a promotional interest rate for up to three years, with terms varying by model. The incentive applies to orders placed between January 9 and March 31, 2026, with delivery required by the end of the first quarter.
The stakes are high in Norway, where electric vehicles dominate new-car registrations. From the vehicles that were sold in 2025, 96% of new cars sold were fully electric. And from this number, Tesla and its Model Y made their dominance felt. This was highlighted by Geir Inge Stokke, director of OFV, who noted that Tesla was able to achieve its stellar results despite its small vehicle lineup.
“Taking almost 20% market share during a year with record-high new car sales is remarkable in itself. When a brand also achieves such volumes with so few models, it says a lot about both demand and Tesla’s impact on the Norwegian market,” Stokke stated.
