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.

The next Tesla earnings call is a week away, and many investors have already started voting on which questions they want answered during the meeting.

Shareholders can submit and vote on questions for the upcoming call using the Say Technologies platform and at the time of writing, the page already has a total of 2.59 million Tesla shares represented in the polls across a total of 6,390 participants. The Q1 2025 Tesla earnings call is set for next Tuesday, April 22 at 2:30 p.m. Pacific, and will be hosted live on X.

Currently, the top questions for the call include those about Tesla’s highly anticipated launch of Full Self-Driving (FSD) Unsupervised and the Cybercab, plans for more affordable models, the uncertain global economic climate, the Optimus robot, and more. Shareholders can continue submitting questions on the platform until Monday, April 21 at 1:00 p.m. Pacific.

Tesla reported delivering 336,681 vehicles and producing 362,215 in the first quarter of the year, and the company noted that it lost several weeks of production as it transitioned to building the new Model Y. The company also reported deploying 10.4 GWh of energy storage products, compared to just 4,053 MWh in the first quarter of last year.

Interestingly, Tesla shifted its wording of the earnings call in this year’s Q1 production and delivery report, instead referring to the upcoming meeting as a “Q1 Company Update.”

Elon Musk continues to push optimistic goal for Tesla Full Self-Driving

Elon Musk continues to push the idea that Teslas will be able to drive themselves to your house this year on their own. It’s perhaps the most committed we’ve seen him toward a timeline.

Elon Musk has always been optimistic about when Tesla would be able to solve Full Self-Driving and what its capabilities would be, and sometimes, he’s been a tad too optimistic.

We have heard for many years that Tesla will solve Full Self-Driving by the “end of this year,” and “this” means whichever year he said it in. But this time, he’s putting all his eggs in the 2025 basket, and it was further reiterated in a recent post from the Tesla CEO on X.

Musk’s Tesla has launched several versions of Full Self-Driving in recent months that are extremely impressive. I’ve tried some of these recently-released versions within the last week, and I’ve grown extremely impressed with the performance of FSD, especially in some situations that are even tricky for humans to maneuver.

However, Tesla’s FSD suite handled it flawlessly. That’s the kind of thing investors and consumers need to see before it is released, especially as we’ve all heard the “this year” speech for nearly a decade. It might be the real thing this time, especially as the company is leaning heavily on the Robotaxi fleet to take it to the next level.

Earlier today, Tesla’s official account on X indicated that your car will be able to drive itself to your house. Musk had a witty and simple reply, something that indicates and reiterates his optimistic outlook for FSD as it continues to be refined and adjusted for what will likely be a June release in Austin, Texas:

Of course, this is not a confirmation that Tesla will roll out Full Self-Driving that is unsupervised within the next few months. It is increasingly obvious that Musk is gaining tons of confidence in what the company is doing, as he has reiterated this end-of-year target on several occasions.

It does not appear that the release of FSD will be a widespread one. Instead, it seems as if Tesla will roll out the Robotaxi fleet in several cities at first, as it has already taken several regulatory steps in Texas and California.

If Tesla is able to come through on this, it would be massive for the company and its investors, especially as the FSD suite is a major point of value for the future. However, not coming through on this timeline would be a massive misstep for the company. Musk’s adamance regarding the 2025 rollout of self-driving features is truly the most committed we’ve ever seen him toward this sort of timeline.

Tesla Cybertruck needs changes before Australia entry, but no guarantees it will arrive

Tesla Cybertruck could make its way to Australia, but the company’s country manager is not convinced quite yet.e

The Tesla Cybertruck is still in need of some changes before it makes its way to Australia, but the country’s director is still unsure whether the vehicle will ever make its way down under.

In March, we reported on Tesla’s intention to bring the Cybertruck to Australia and potentially New Zealand. Country Manager Thom Drew said Tesla had intentions to bring the truck to the market, especially as there is a lack of a “real workhorse, full EV that has the range and capability that Cybertruck does.”

Tesla plans to bring Cybertruck to new market for a big advantage

Now, there has been more criticism about the concerns for the vehicle to be approved for operation in Australia. Various people have said that the Cybertruck would not comply with Australian Design Rules, according to EVCentral. But Drew believes that those critics are simply spouting their opinions.

At the Melbourne Motor Show, Drew said:

“A lot of those concerns are unfounded around its compliance. There is a lot about it that works within the Australian compliance system. Are there changes required? That is absolutely part of the discussion with headquarters at the moment.”

It sounds as if Tesla might not have to change the truck but potentially redesign an all-new pickup design. The new truck will have to be right-hand drive, and steer-by-wire has been mentioned in some discussions as a potential issue for passing the ADRs.

Additionally, the shape and angles of the Cybertruck have been criticized in several markets as potentially dangerous to pedestrians. However, if you take the angular design and steer-by-wire away, it’s not really a Cybertruck any longer; it might end up being Tesla’s first traditional pickup design.

Currently, Drew remains skeptical that the Cybertruck will ever break into the Australian market. He said that a lot of these changes would require significant adjustments to the Cybertruck manufacturing program, as right-hand-drive units would have to be produced on the production lines in Gigafactory Texas. This could throw a wrench into the production timeline.

He added:

“I think the consideration we have to make a decision on, as a business, is Australia really the only right-hand drive market where it’s suitable? That is obviously part of the consideration for the program. I am not confident it’s coming, but we are discussing it. Locally, we want to see it [Cybertruck] here but it’s certainly not a done deal just yet.”

It seems somewhat unlikely as of right now that the Cybertruck will make its way into a new market.
