With the Tesla Model Y just beginning first deliveries a few weeks ago, owners are getting their first tastes of how the new all-electric crossover performs. Brian Jenkins from YouTube channel i1Tesla took his experiments a few steps further and recorded the Model Y Performance 0-60 MPH acceleration time based on the factory 21″ Uberturbine wheel size and several aftermarket wheel options.

Brian brought his Model Y Performance to a research center known as NCCAR in Northhampton County, North Carolina, to test acceleration rates from 0-60 MPH. The tests were performed with the 21″ Uberturbine wheels that come standard with the Model Y’s optional performance upgrade, 19″ TSW wheels from EVtuning.com, and 18″ MWO3 Forged rims from Martian Wheels.

The Uberturbine front wheels weigh 64.8 pounds, with the slightly wider rear wheels weighing 68.6 pounds with the tires attached according to a wheel weight test performed by Brian at the NCCAR facility. Meanwhile, the 19″ TSW wheels weigh 47.6 pounds with a tire and 23 pounds on their own. The 18″ Martian MWO3 Forged wheels weigh 40.7 pounds with a tire installed onto the rim. Martian’s website states the rim weighs only 17.3 pounds without a tire attached to them.

The first runs of the vehicle were with the 21″ Uberturbine rims. Brian ran four times with these wheels on the vehicle, utilizing two runs to test its normal 0-60 MPH time, one run using Tesla’s Slip Start feature, and one run using the Model Y’s Off-Road setting. The tests were performed with a battery charge of between 82% and 74%. A Dragy GPS recorded the times.

Tesla Model Y 0-60 mph with 21″ Tesla Uberturbine Wheels (68.6 pounds with tire)

  • Run 1 – Normal: 0-60 MPH in 3.77 seconds
  • Run 2 – Normal: 0-60 MPH in 5.74 seconds
  • Run 3 – Slip Start: 0-60 MPH in 3.81 seconds
  • Run 4 – Off-Road: 0-60 MPH in 3.83 seconds

The next two runs were performed with both the 19″ TSW and 18″ MWO3 Wheels. Because of the lighter weight, the runs with these tires were noticeably faster.

Tesla Model Y 0-60 mph with 19″ TSW Wheels (47.6 pounds with tire, 23 pounds without tire)

  • Run 1 – Normal: 0-60 MPH in 3.45 seconds

 

Tesla Model Y 0-60 mph with 18″ Martian MWO3 Forged Wheels (40.7 pounds with tire, 17.3 pounds without tire)

  • Run 1 – Normal: 0-60 MPH in 3.42 seconds

 

The lighter and smaller TSW wheels shaved .29 seconds off of the Tesla Uberturbine wheels, but the even smaller and lighter 18″ Martian rims managed to trim almost a third of a second off of the quarter-mile time with a .32 second faster 0-60 time.

The size of the wheel also affects the range of the vehicle. The EPA’s current rating of the Model Y Performance states the car offers 315 miles of range, when paired with the 19″ Gemini wheels, and 280 miles of range with the larger and heavier 21″ Uberturbine wheels.

Comparisons of the Model 3’s different rim sizes affect the range as well, where the 20″ wheels give 299 miles, 19″ wheels offer 304 miles, and 18″ will give the driver 322 miles of driving range.

We’ve embedded Brian’s video below, which shows how Model Y’s 0-60 MPH acceleration varies by wheel and tire sizing.

Tesla isn’t joking about building Optimus at an industrial scale: Here we go

Tesla’s Optimus factory in Texas targets 10 million robots yearly, with 5.2 million square feet under construction.

Published

Tesla’s Q1 2026 Update Letter, released today, confirms that first generation Optimus production lines are now well underway at its Fremont, California factory, with a pilot line targeting one million robots per year to start. Of bigger note is a shared aerial image of a large piece of land adjacent to Gigafactory Texas, that Tesla has prominently labeled “Optimus factory site preparation.”

Permit documents show Tesla is seeking to add over 5.2 million square feet of new building space to the Giga Texas North Campus by the end of 2026, at an estimated construction investment of $5 billion to $10 billion. The longer term production target for that facility is 10 million Optimus units per year. Giga Texas already sits on 2,500 acres with over 10 million square feet of existing factory floor, and the North Campus expansion is being built to support multiple projects, including the dedicated Optimus factory, the Terafab chip fabrication facility (a joint Tesla/SpaceX/xAI venture), a Cybercab test track, road infrastructure, and supporting facilities.

Texas makes strategic sense beyond the existing infrastructure. The state’s tax structure, lower labor costs relative to California, and the proximity to Tesla’s AI training cluster Cortex 1 and 2, both located at Giga Texas and now totaling over 230,000 H100 equivalent GPUs, means the Optimus software stack and the factory producing the hardware will share the same campus. Tesla’s Q1 report also confirmed completion of the AI5 chip tape out in April, the inference processor designed specifically to power Optimus units in the field.

As Teslarati reported, the Texas facility is intended to house Optimus V4 production at full scale. Musk told the World Economic Forum in January that Tesla plans to sell Optimus to the public by end of 2027 at a price between $20,000 and $30,000, stating, “I think everyone on earth is going to have one and want one.” He has previously pegged long term demand for general purpose humanoid robots at over 20 billion units globally, citing both consumer and industrial use cases.

Why SpaceX just made a $60 billion bet on AI coding ahead of historic IPO

SpaceX has secured an option to acquire Cursor AI for $60 billion ahead of its historic IPO.

Published

on

By

SpaceX announced today it has struck a deal with AI coding startup Cursor, securing the option to acquire the company outright for $60 billion later this year, while committing $10 billion for joint development work in the interim. The announcement described the partnership as building “the world’s best coding and knowledge work AI,” and comes just days after Cursor was separately reported to be raising $2 billion at a valuation above $50 billion.

The move makes strategic sense given where each company currently stands. Cursor currently pays retail prices to Anthropic and OpenAI to the same companies competing directly against it with Claude Code and Codex. That means every dollar of revenue Cursor earns partially funds its own competition. With SpaceX bringing computational infrastructure to the Cursor platform, that could reduce Cursor’s dependence on OpenAI and Anthropic’s Claude AI as its providers. Access to SpaceX’s Colossus supercomputer, with compute equivalent to one million Nvidia H100 chips, gives Cursor the infrastructure to run and train its own models at a scale it could never afford independently. That one change restructures the entire unit economics of the business.

Elon Musk teases crazy outlook for xAI against its competitors

Cursor’s $2 billion in annualized revenue and enterprise reach across more than half of Fortune 500 companies gives SpaceX something its xAI subsidiary currently lacks, which is a proven, fast-growing software business with real enterprise distribution.

For Cursor, SpaceX’s $10 billion in joint development funding is transformational. Cursor raised $3.3 billion across all of 2025 to reach that $2 billion in revenue. A single $10 billion commitment from SpaceX, even as a development payment rather than an acquisition, dwarfs everything Cursor has raised in its entire existence. That capital accelerates product development, enterprise sales infrastructure, and proprietary model training simultaneously.

The timing is deliberate. SpaceX filed confidentially with the SEC on April 1, 2026, targeting a June listing at a $1.75 trillion valuation, in what would be the largest public offering in history. The company is expected to begin its roadshow the week of June 8, with Bank of America, Goldman Sachs, JPMorgan, and Morgan Stanley serving as underwriters. Adding Cursor to the portfolio before that roadshow gives IPO investors a concrete enterprise software revenue story to price in, alongside rockets and satellite internet.

The deal also addresses a weakness that became visible after February’s xAI merger. Several xAI co-founders departed following that acquisition, and SpaceX had already hired two Cursor engineers, signaling where its AI talent strategy was heading. Cursor, for its part, faces a pricing disadvantage competing against Anthropic’s Claude Code.

Whether SpaceX exercises the full acquisition option before its IPO or after remains the open question. Either way, this deal reshapes what investors will be buying into when SpaceX goes public.

Tesla is sending its humanoid Optimus robot to the Boston Marathon

Tesla’s Optimus robot is heading to the Boston Marathon finish line

Tesla’s Optimus humanoid robot will be stationed at the Tesla showroom at 888 Boylston Street in Boston, right along the final stretch of the Boston Marathon today, ready to cheer on runners and pose for photos with spectators.

According to a Tesla email shared by content creator Sawyer Merritt on X, Optimus will be at the Boston Boylston Street showroom on April 20, coinciding with Marathon Monday weekend. The Boston Marathon finishes on Boylston Street, and the surrounding area draws hundreds of thousands of spectators along with international broadcast coverage. Placing Optimus there puts it in front of a massive public audience at zero advertising cost.

The Tesla showroom is at 888 Boylston Street, between Gloucester Street and Fairfield Street. The final mile of the marathon runs directly along Boylston Street, with runners passing the big stores before reaching the finish line at Copley Square.

Optimus was first announced at Tesla’s AI Day event on August 19, 2021, when Elon Musk presented a vision for a general-purpose robot designed to take on dangerous, repetitive, and unwanted tasks. In March 2026, Optimus appeared at the Appliance and Electronics World Expo in Shanghai, where on-site staff stated that mass production of the robot could begin by the end of 2026. Before that, it showed up at the Tesla Hollywood Diner opening in July 2025 and at a Miami showroom event in December 2025.

Tesla’s well-calculated display of Optimus gives the public a low-pressure first encounter with a robot that Tesla is preparing  to soon deploy at scale. The company has previously indicated plans to manufacture Optimus robots at its Fremont facility at up to 1 million units annually, with an Optimus production line at Gigafactory Texas targeting 10 million units per year.

Musk has said that Optimus “has the potential to be more significant than the vehicle business over time,” and separately that roughly 80 percent of Tesla’s future value will come from the robot program. Whether that holds depends on production execution. For now, Boston gets a preview of what that future looks like, standing at the finish line on Boylston Street while 32,000 runners pass by.
