Tesla’s SilLion acquisition and Roadrunner batteries will make EVs inevitable

Tesla’s Project Roadrunner is expected to usher in a new generation of batteries that would widen the gap between the electric car maker and its rivals in the EV industry. To accomplish this goal, Tesla has been acquiring companies whose technologies would allow it to develop and produce the best batteries on the market, bar none. One of these companies, SilLion, could very well have developed innovations that would make Teslas, and in turn, EVs, inevitable.

Just last month, Elon Musk stated on Twitter that what really matters in batteries is the cathode and anode material. Musk added that while there are numerous choices available, nickel cathodes and carbon silicon anodes really work great. This is right in line with SilLion’s work. Back in 2017, the company outlined the results of its work on batteries, which, interestingly, is focused on high-loading silicon anodes and nickel-rich cathodes.

According to SilLion, it has manufactured early 2.5 Ah prototypes of its battery cells that are capable of achieving greater than 300 Wh/kg, a prerequisite step to ensure that the company’s tech could be inserted into the markets. What’s more, SilLion’s cell technology, through the utilization of lower cost materials and manufacturing capabilities, is poised to be 30% less expensive than state of the art and industry leading lithium ion batteries at the time.

The reasons behind the acquisition of SilLion have not been disclosed by Tesla, though it is not difficult to speculate that the firm’s battery breakthroughs could be a key factor that attracted the electric car maker. Tesla’s endgame, after all, is developing vehicles and energy storage products with high energy batteries that are also cost effective to produce. If Tesla could accomplish this, it could reach and exceed price parity with gas powered vehicles, and perhaps even more. With such a breakthrough, Tesla could all but ensure that EVs will become inevitable in the auto market.

As noted by Tesla owner enthusiast Sean Mitchell in a recent video, SilLion’s tech, if integrated with the work of other companies like Maxwell that the electric car maker has acquired over the years, could make Elon Musk’s statements about “mind blowing” innovations on Battery Day accurate. Of course, mass manufacturing these next generation cells is a completely different story. Fortunately, such a challenge seems to be addressed by Project Roadrunner, at least up to a point.

Considering the potential output of Project Roadrunner, Tesla’s next generation cells would likely be a perfect match for the upcoming Plaid Model S and Model X. Both vehicles have been announced by Elon Musk last year, and both are expected to be equipped with the best battery and powertrain tech that Tesla has to offer. The Model S and Model X are relatively low volume vehicles compared to the Model 3 and Model Y, after all, which should allow the Roadrunner line to produce enough batteries for the flagship EVs.

Tesla scrambles after Musk sidekick exit, CEO takes over sales

Tesla CEO Elon Musk is reportedly overseeing sales in North America and Europe, Bloomberg reports.

Tesla scrambled its executives around following the exit of CEO Elon Musk’s sidekick last week, Omead Afshar. Afshar was relieved of his duties as Head of Sales for both North America and Europe.

Bloomberg is reporting that Musk is now overseeing both regions for sales, according to sources familiar with the matter. Afshar left the company last week, likely due to slow sales in both markets, ending a seven-year term with the electric automaker.

Tesla’s Omead Afshar, known as Elon Musk’s right-hand man, leaves company: reports

Afshar was promoted to the role late last year as Musk was becoming more involved in the road to the White House with President Donald Trump.

Afshar, whose LinkedIn account stated he was working within the “Office of the CEO,” was known as Musk’s right-hand man for years.

Additionally, Tom Zhu, currently the Senior Vice President of Automotive at Tesla, will oversee sales in Asia, according to the report.

It is a scramble by Tesla to get the company’s proven executives over the pain points the automaker has found halfway through the year. Sales are looking to be close to the 1.8 million vehicles the company delivered in both of the past two years.

Tesla is pivoting to pay more attention to the struggling automotive sales that it has felt over the past six months. Although it is still performing well and is the best-selling EV maker by a long way, it is struggling to find growth despite redesigning its vehicles and launching new tech and improvements within them.

The company is also looking to focus more on its deployment of autonomous tech, especially as it recently launched its Robotaxi platform in Austin just over a week ago.

However, while this is the long-term catalyst for Tesla, sales still need some work, and it appears the company’s strategy is to put its biggest guns on its biggest problems.

Tesla has rolled out a series of quiet upgrades to its Model 3 and Model Y in China, enhancing range and performance for long-range variants. The updates come with a price hike for the Model 3 Long Range All-Wheel Drive, which now costs RMB 285,500 (about $39,300), up RMB 10,000 ($1,400) from the previous price.

Model 3 gets acceleration boost, extended range

Tesla’s long-range Model 3 now comes with a higher CLTC-rated range of 753 km (468 miles), up from 713 km (443 miles), and a faster 0–100 km/h acceleration time of 3.8 seconds, down from 4.4 seconds. These changes suggest that Tesla has bundled the previously optional Acceleration Boost for the Model 3, once priced at RMB 14,100 ($1,968), as a standard feature.

Delivery wait times for the long-range Model 3 have also been shortened, from 3–5 weeks to just 1–3 weeks, as per CNEV Post. No changes were made to the entry-level RWD or Performance versions, which retain their RMB 235,500 and RMB 339,500 price points, respectively. Wait times for those trims also remain at 1–3 weeks and 8–10 weeks.

Model Y range increases, pricing holds steady

The Model Y Long Range has also seen its CLTC-rated range increase from 719 km (447 miles) to 750 km (466 miles), though its price remains unchanged at RMB 313,500 ($43,759). The model maintains a 0–100 km/h time of 4.3 seconds.

Tesla also updated delivery times for the Model Y lineup. The Long Range variant now shows a wait time of 1–3 weeks, an improvement from the previous 3–5 weeks. The entry-level RWD version maintained its starting price of RMB 263,500, though its delivery window is now shorter at 2–4 weeks.

The figure represents a 49.3% increase from the previous week and a 46.7% improvement year-over-year, suggesting growing domestic momentum for the electric vehicle maker in Q2’s final weeks.

Q2 closes with a boost despite year-on-year dip

The strong week helped lift Tesla’s performance for the quarter, though Q2 totals remain down 4.6% quarter-over-quarter and 10.9% year-over-year, according to industry watchers. Despite these declines, the last week of June stands as the second-highest of 2025 and the best-performing week of the quarter. 

As per industry watchers, Tesla China delivered 15,210 New Model Y units last week, the highest weekly tally since the vehicle’s launch. The Model 3 followed with 5,470 deliveries during the same period. Tesla’s full June and Q2 sales data for China are expected to be released by the China Passenger Car Association (CPCA) in the coming days.

Earlier this week, Tesla introduced minor updates to the long-range versions of the Model 3 and Model Y in China. The refreshed Model 3 saw a modest price increase, while pricing for the updated Model Y Long Range variant remained unchanged. These adjustments come as Tesla continues refining its China lineup amid shifting local demand and increased competition from domestic brands.
