Elon Musk gives tips to optimize Tesla Model 3 Performance, teases 0-60 mph in 3.3 seconds
Elon Musk recently gave some tips for would-be owners of the Model 3 Performance — in order to fully optimize the electric car’s capabilities and speed, equipping it with stickier and wider tires at the rear is recommended. According to Musk, the Model 3 Performance would likely be capable of sprinting from 0-60 mph in 3.3 seconds with optimized rims and tires.
Musk’s advice came as a response to Tesla enthusiast Ryan McCaffrey, who mentioned an observation from the Wall Street Journal‘s Dan Neil, who recently reviewed the Model 3 Performance. According to Neil, the Model 3 Performance is already an excellent car, but it would be even better if it had a better set of tires. Musk responded, stating that Tesla had to give up some of the car’s grip to optimize its range. For drivers aiming for top performance, Musk stated that upgrading the tires and wheels can give the car an extra boost.
Definitely. We gave up some grip & width in exchange for range. Would recommend stickier tires & wider on rear for best performance. You might get 3.3 sec 0-60 mph or better with optimized rims & tires.

As could be seen in Tesla’s configuration page for the vehicle, the Model 3 Performance is capable of going from a dead stop to 60 mph in 3.5 seconds, thanks to its twin electric motors that deliver instant torque. The electric car also has a top speed of 155 mph, as well as a range of 310 miles on a single charge. In true Tesla tradition, Elon Musk teased back in May that the Model 3 Performance’s power output could be a bit higher than expected.
Tesla already has a reputation for making its vehicles faster over time. Just last year, Tesla opted to “uncork” the 75D variants of the Model S and Model X. The Model S 75D, for example, had a notable boost in acceleration after the vehicle’s 0-60 mph time was reduced from 5.2 seconds to 4.2 seconds through a free software update. The Model X 75D also had a similar performance bump, with the all-electric SUV’s 0-60 time dropping from 6.0 seconds to 4.9 seconds. Thus, with Elon Musk’s announcement last May, expectations were high that Tesla would likely improve the Model 3 Performance’s acceleration and capabilities over time as well. Talks of a Ludicrous Mode upgrade, which Musk reacted positively to before, were also reiterated.
When he announced the vehicle’s specs on Twitter, Elon Musk stated that the Model 3 Performance, with its 0-60 mph time of 3.5 seconds, would be 15% faster on the track than a BMW M3. Considering that a simple improvement in wheels and tires would likely cause the vehicle to accelerate .20 seconds faster, Musk’s estimates for the Model 3 Performance might actually end up being rather conservative.
When Tesla announced the Model S P85D back in 2014, the company unveiled the vehicle’s Insane Mode, which allowed the family sedan to accelerate from 0-60 mph in 3.2 seconds, rivaling the McLaren F1, a legendary supercar that Musk admits is one of the best cars to ever be made. The McLaren F1 has a 0-60 time of 3.2 seconds — just .10 seconds faster than the raw acceleration of the Model 3 Performance with wider rear tires.

SpaceX’s newest logo confirms everything about what it’s become
SpaceX officially absorbed xAI under the SpaceXAI brand, completing the largest private merger in history.
SpaceX made its corporate transformation official in May 2026 when Elon Musk posted on X that xAI would cease to exist as a standalone company. “xAI will be dissolved as a separate company, so it will just be SpaceXAI, the AI products from SpaceX,” he wrote.
A new SpaceXAI logo was announced today, visually embedding the xAI letters inside the SpaceX identity, which can be seen as a deliberate design choice that signals the merger is not a partnership but a full absorption and XAi a core function of the same company. The same way Starlink is not a separate brand but a SpaceX product. The announcement closed the loop on a process that began February 2, 2026, when SpaceX acquired xAI in the largest private merger in history, valued at $1.25 trillion. SpaceX at $1 trillion and xAI at $250 billion.
We are now @SpaceXAI. pic.twitter.com/ema66xDWC9

The reason SpaceX bought xAI was stated plainly by Musk at the time of the deal: to build orbital data centers. SpaceX had simultaneously filed with the FCC to launch up to one million satellites designed to function as AI compute nodes in low Earth orbit, escaping what Musk described as the energy constraints limiting AI development on Earth.
xAI provided the AI software stack, with Grok, the X platform, and the Colossus supercomputer infrastructure in Memphis with over 220,000 NVIDIA GPUs, while SpaceX provided the rockets, Starlink, and the capital base to fund it. The two companies needed each other. xAI was burning $2.5 billion in losses on $250 million in revenue. SpaceX was generating an estimated $8 billion in profit on $15 billion in revenue and needed an AI narrative to command the valuation it was targeting for its IPO.
What SpaceX has done, regardless of how the orbital AI vision ultimately plays out, is walk into a public market as something no company has been before: a rocket manufacturer, satellite internet provider, AI software company, social media platform, and supercomputer operator under one ticker. Whether that combination is worth $2 trillion depends entirely on which of those businesses you believe in most.

Tesla Robotaxi’s official account detailed these elements, noting the Cybercab’s focus on accessibility, especially noting the Braille lettering and additional space for service animals.
How Tesla Will Transform Mobility for the Blind
Autonomous vehicles like the Cybercab promise revolutionary independence for the roughly 2.2 million visually impaired Americans. Traditional barriers—reliance on sighted drivers, costly paratransit, or limited public transit—often restrict spontaneous travel. Tesla Full Self-Driving aims to eliminate the need for a human operator, enabling on-demand, door-to-door rides via simple app hailing with voice guidance.
Users gain freedom to work, socialize, shop, or attend events anytime without scheduling hassles or safety concerns. This reduces isolation, boosts employment opportunities, and enhances quality of life, turning mobility from a dependency into true personal autonomy.
The NFB demonstration not only gathered valuable feedback but also generated excitement about a future where technology levels the playing field. By prioritizing inclusive design, Tesla advances a vision of transportation that serves everyone, potentially reshaping daily life for blind individuals and setting a standard for the autonomous industry.
As Cybercab deployment scales, these accessibility innovations could mark a significant step toward equitable mobility.

Tesla challenges startups to score a gig inside its most advanced European factory
Tesla is challenging startups to bring their best battery tech directly to Gigafactory Berlin.
Tesla has issued an open challenge to startups across Europe, inviting them to bring their best battery technology directly to the floor of Gigafactory Berlin. The program, called the JUNI x Tesla Battery Cell Giga Challenge, opened applications this month with a deadline of July 24, 2026, and is targeting startups with solutions that can make battery cell manufacturing faster, cheaper, safer, and more scalable at an industrial level.
The timing of the challenge is directly tied to Tesla’s most aggressive European battery investment yet. On May 12, 2026, Giga Berlin plant manager André Thierig announced a $250 million investment to scale the factory’s annual 4680 cell production capacity from 8 GWh to 18 GWh, more than doubling the previous target set just months earlier in December 2025. Thierig confirmed the expansion on X, saying the investment “will enable 18 GWh of annual 4680 cell production and create more than 1,500 new jobs.” Combined with a previously announced battery investment at the Grunheide site now approaches $1.2 billion.
Today, we announced a $ 250m investment for our Giga Berlin Cell factory. This will enable 18GWh of annual 4680 cell production and create more than 1500 new jobs. Good news during challenging times for the German industry. pic.twitter.com/ou4SWMfWh9

The challenge is looking specifically for startups with proven solutions across five categories: materials, equipment, operations, automation, and artificial intelligence. Applications are screened directly by Tesla’s cell manufacturing team in Grunheide, and the strongest submissions move through technical discussions, a pitch day in front of Tesla stakeholders, and potentially a paid pilot project with the cell team. Tesla is not looking for ideas at concept stage. The program requires applicants to demonstrate working prototypes, test data, or prior pilots before being considered.
The historical context matters here. Elon Musk first announced plans for what he called the world’s largest battery cell production facility alongside the Giga Berlin car factory back in 2020, targeting up to 250 GWh of annual capacity. Those plans were shelved in 2022 when Tesla shifted its battery investment focus to the United States to take advantage of Inflation Reduction Act incentives. The revival of cell production at Giga Berlin, now backed by over $1 billion in committed capital, represents a return to an ambition that was set aside for three years. As Teslarati has reported, the 4680 format is central to Tesla’s long-term cost reduction strategy across vehicles, energy storage, including the Tesla Semi and Cybercab.
By opening the challenge to outside startups, Tesla is acknowledging that reaching 18 GWh at Grunheide will require technology it does not currently have in-house, and it is willing to pay for the right solutions. For a startup in the battery supply chain, a paid pilot with Tesla’s European cell team is as close to a direct commercial path as the industry offers.
