All 90 kWh Battery Teslas May Already Have Ludicrous Mode

A curious Tesla owner took photos of the battery sticker on 2 cars with 90 kWh batteries, 1 with Ludicrous and 1 without. The sticker on both was the same.

By now, we all know that the secret to Tesla’s new Ludicrous Mode was a so-called smart fuse that could handle up to 1,500 amps, instead of the 1,300 amps supported by the current generation P85D. That, and an upgrade to the material used on the main battery pack contact allowed Tesla to safely increase the max battery pack output.

P90D owners can opt for Ludicrous Mode for an additional $10,000, but what does this fee actually buy you?

Tesla Motors Club member ArtInCT unpacked his trusty camera the other day at his local Tesla store, where a Model S P90D with Ludicrous Mode was parked next to a standard non-Ludicrous Mode P90D. He crawled under both cars and snapped pictures of the sticker on the main traction battery of each car.

Here’s what his camera captured. First, the battery installed in the Ludicrous enabled P90D:

Now, the sticker on the non-Ludicrous enabled P90D:

P90D-90kWh-Battery-Code-Serial

Notice anything interesting? That’s right. Both stickers have the same exact part number, leading to speculation that the smart fuse is installed in all 90 kWh batteries. If that is the case, then is enabling Ludicrous Mode as simple as a software upgrade? And if that is true, why does it cost $10,000?

TMC member mgboyes posted, “IMO it’s highly likely that all 90 kWh packs (even the ones in the 90D) have the upgraded fuse and contactor. I bet you can get a P90D upgraded to a P90DL by software after delivery… but I bet they charge you more than $10k for the privilege.”

Senior member yobigd20 agreed: “If I recall correctly, Elon stated that the 90 kWh packs have the upgraded fuse in place. So yes, it’s merely a software switch to enable Ludicrous Mode.”

There is no official word from the company but until there is, it seems reasonable to assume that all cars with the 90 kWh battery pack have the potential to be upgraded to Ludicrous Mode — for a price.

Tesla lands massive deal to expand charging for heavy-duty electric trucks

Tesla has landed a massive deal to expand its charging infrastructure for heavy-duty electric trucks — and not just theirs, but all manufacturers.

Tesla entered an agreement with Pilot Travel Centers, the largest operator of travel centers in the United States. Tesla’s Semi Chargers, which are used to charge Class 8 electric trucks, will be responsible for providing energy to various vehicles from a variety of manufacturers.

The first sites are expected to open later this Summer, and will be built at select locations along I-5 and I-10, major routes for commercial vehicles and significant logistics companies. The chargers will be available in California, Georgia, Nevada, New Mexico, and Texas.

Each station will have between four and eight chargers, delivering up to 1.2 megawatts of power at each stall.

The project is the latest in Tesla’s plans to expand Semi Charging availability. The effort is being put forth to create more opportunities for the development of sustainable logistics.

Senior Vice President of Alternative Fuels at Pilot, Shannon Sturgil, said:

“Helping to shape the future of energy is a strategic pillar in meeting the needs of our guests and the North American transportation industry. Heavy-duty charging is yet another extension of our exploration into alternative fuel offerings, and we’re happy to partner with a leader in the space that provides turnkey solutions and deploys them quickly.”

Tesla currently has 46 public Semi Charger sites in progress or planned across the United States, mostly positioned along major trucking routes and industrial areas. Perhaps the biggest bottleneck with owning an EV early on was charging availability, and that is no different with electric Class 8 trucks. They simply need an area to charge.

Tesla is spearheading the effort to expand Semicharging availability, and the latest partnership with Pilot shows the company has allies in the program.

The company plans to build 50,000 units of the Tesla Semi in the coming years, and with early adopters like PepsiCo, DHL, and others already contributing millions of miles of data, fleets are going to need reliable public charging.

Tesla is partnering with other companies for the development of the Semi program, most notably, a conglomeration with Uber was announced last year.

The ride-sharing platform plans to launch the Dedicated EV Fleet Accelerator Program, which it calls a “first-of-its-kind buyer’s program designed to make electric freight more affordable and accessible by addressing key adoption barriers.”

The Semi is one of several projects that will take Tesla into a completely different realm. Along with Optimus and its growing Energy division, the Semi will expand Tesla to new heights, and its prioritization of charging infrastructure.

Elon Musk’s tunneling startup, The Boring Company, has welcomed its newest Vegas Loop station at the Fontainebleau Las Vegas.

The Fontainebleau is the latest resort on the Las Vegas Strip to embrace the tunneling startup’s underground transportation system.

Fontainebleau Loop station

The new Vegas Loop station is located on level V-1 of the Fontainebleau’s south valet area, as noted in a report from the Las Vegas Review-Journal. According to the resort, guests will be able to travel free of charge to the stations serving the Las Vegas Convention Center, as well as to Loop stations in Encore and Westgate.

The Fontainebleau station connects to the Riviera Station, which is located in the northwest parking lot of the convention center’s West Hall. From there, passengers will be able to access the greater Vegas Loop.

Vegas Loop expansion

In December, The Boring Company began offering Vegas Loop rides to and from Harry Reid International Airport. Those trips include a limited above-ground segment, following approval from the Nevada Transportation Authority to allow surface street travel tied to Loop operations.

Under the approval, airport rides are limited to no more than four miles of surface street travel, and each trip must include a tunnel segment. The Vegas Loop currently includes more than 10 miles of tunnels. From this number, about four miles of tunnels are operational.

The Boring Company President Steve Davis previously told the Review-Journal that the University Center Loop segment, which is currently under construction, is expected to open in the first quarter of 2026. That extension would allow Loop vehicles to travel beneath Paradise Road between the convention center and the airport, with a planned station located just north of Tropicana Avenue.

Tesla leases new 108k-sq ft R&D facility near Fremont Factory

Tesla has expanded its footprint near its Fremont Factory by leasing a 108,000-square-foot R&D facility in the East Bay. 

The lease adds to Tesla’s presence near its primary California manufacturing hub as the company continues investing in autonomy and artificial intelligence.

A new Fremont lease

Tesla will occupy the entire building at 45401 Research Ave. in Fremont, as per real estate services firm Colliers. The transaction stands as the second-largest R&D lease of the fourth quarter, trailing only a roughly 115,000-square-foot transaction by Figure AI in San Jose.

As noted in a Silicon Valley Business Journal report, Tesla’s new Fremont lease was completed with landlord Lincoln Property Co., which owns the facility. Colliers stated that Tesla’s Fremont expansion reflects continued demand from established technology companies that are seeking space for engineering, testing, and specialized manufacturing.

Tesla has not disclosed which of its business units will be occupying the building, though Colliers has described the property as suitable for office and R&D functions. Tesla has not issued a comment about its new Fremont lease as of writing.

AI investments

Silicon Valley remains a key region for automakers as vehicles increasingly rely on software, artificial intelligence, and advanced electronics. Erin Keating, senior director of economics and industry insights at Cox Automotive, has stated that Tesla is among the most aggressive auto companies when it comes to software-driven vehicle development.

Other automakers have also expanded their presence in the area. Rivian operates an autonomy and core technology hub in Palo Alto, while GM maintains an AI center of excellence in Mountain View. Toyota is also relocating its software and autonomy unit to a newly upgraded property in Santa Clara.

Despite these expansions, Colliers has noted that Silicon Valley posted nearly 444,000 square feet of net occupancy losses in Q4 2025, pushing overall vacancy to 11.2%.
