Performance Gains after P85D Ludicrous Mode Upgrade
TMC member thimel recently had the Ludicrous mode upgrade installed on his Model S P85D. He carefully measured the performance of his car before and after, and found that Ludicrous mode is worth about a half second to 60 mph and a noticeable increase in power at all speeds up to 80.
Just how much faster is the the P85D with Ludicrous Mode upgrade? According to Tesla Motors Club (TMC) member thimel, the performance gains are significant, to the tune of 19% more power above 30 mph and a drop in 0-60 time from 3.2 to 2.9 seconds. Quarter mile time also drops from an already quick 11.8 seconds to an astounding 11.5 seconds.
thimel carefully measured the performance of the P85D both before and after the Ludicrous Mode upgrade. The performance data was then meticulously charted and plotted, painting a clear picture of the performance differences from the $5,000 retrofit.

According to thimel’s post from the TMC forum, “I started the before Ludicrous tests early in the morning and had not driven the car for many hours, but had charged it that night. The ambient temperature in my garage that morning was 59 degrees and it was 50 degrees outside during the tests. I started with a 90% charge and by the time I was done the charge was 70%. Creep mode was off to help avoid a very slow start. Insane mode was on of course. Climate control was off.
“I drove a few miles before starting the first test but did nothing else to warm the battery. I drove 5 miles at moderate acceleration and speeds between acceleration passes. This was both to give a chance for things to cool down and to return me to the same starting point for each acceleration pass.data shows the Ludicrous mode upgrade it worth nearly a half second in the sprint to 60 mph and several more miles per hour at the end of the quarter mile. ”
Next he charted his power and speed against time and found power to range from 380 kW, before the Ludicrous upgrade, to 451 kW after the upgrade with the Max Battery Power setting on. The setting heats the Tesla battery to a higher temperature thereby reducing its impedance and increasing current to provide short term acceleration and performance gains.
The biggest boost in performance after the Ludicrous upgrade happens above 30 mph. Below that, performance is about the same. But with Ludicrous mode engaged, there is a sizable increase in available torque. Before the upgrade, lateral acceleration reaches approximately 1.15 g at 15 mph, then falls below 1 g after 25 mph. After the upgrade, lateral acceleration peaks at 1.1 g and continues to pull over 1 g until slightly past 30+ mph. Most notably, the acceleration is consistently above the pre-Ludicrous Mode upgrade all the way until 80 mph.

In his notes, thimel makes some interesting points. “Above 30 mph, ludicrous clearly has more power. This is seen directly with the PowerTools readout…..which shows the maximum power increased from 380 to 451 kW, a 19% increase and by the shorter times to achieve speeds above 30 mph. The max power measured from the battery was 451 kW. This compares to 458 kW that Pete90D measured on his P90DL. So the battery doesn’t make much of a difference. The 0-60 time I got of 2.89 is also nearly identical to that Pete90D got of 2.901.”
He ends his post with this conclusion: “The P85D with ludicrous upgrade is significantly faster than without. There is 19% more power above 30 mph, 0-60 time drops from 3.2 to 2.9 seconds and the quarter mile time drops from 11.8 to 11.5. So it was fast before and is faster now. You get about two-thirds of the improvement if you don’t heat the battery with max battery power.”

NASA’s first human outpost on the Moon starts now – SpaceX on deck
NASA named the rovers, landers, and vendors that will build America’s first Moon Base.
NASA has laid out its most detailed Moon Base plan to date, describing a permanent outpost near the Moon’s south pole that the agency intends to build over the coming decade as a direct stepping stone to Mars. “The Moon Base will be America’s and humanity’s first outpost on another celestial world,” NASA Administrator Jared Isaacman said, adding that every mission crewed and uncrewed “will be a learning opportunity as we return to the lunar surface, build the infrastructure to stay, and master the skills required to live and operate in one of the most demanding and dangerous environments imaginable.”
The plan is structured in three phases involving both uncrewed and crewed missions to deliver equipment, vehicles, and infrastructure to the surface, with the first three moon base missions targeted to launch before the end of 2026.
Moon Base I, targeting fall 2026, will use Blue Origin’s Blue Moon Mark 1 lander to deliver scientific instruments to the Shackleton Connecting Ridge, the same region where Artemis astronauts will land. Moon Base II will send Astrobotic’s Griffin lander carrying more than 1,100 pounds of cargo including Astrolab’s FLIP rover to begin developing mobility systems on the surface. Moon Base III will carry the Lunar Vertex science mission on Intuitive Machines’ Nova-C Trinity lander to study lunar swirls near the south pole, with ESA and Korean science payloads aboard.
On the rover side, NASA awarded Astrolab $219 million and Lunar Outpost $220 million to build the first phase of Lunar Terrain Vehicles, with both rovers targeted for deployment to the lunar surface by 2028. Astrolab’s crewed rover weighs roughly 2,000 pounds and can reach over 6 mph. Lunar Outpost’s Pegasus rover can operate autonomously or via remote control at over 9 mph. Blue Origin separately received $188 million with an option worth $280.4 million to deliver cargo landers for rover transport.
NASA also confirmed that MoonFall, a mission deploying four survey drones to scout Artemis landing sites, has selected Firefly Aerospace to build the transport spacecraft, with a 2028 launch target.
SpaceX sits at the center of that commercial layer. SpaceX holds the NASA Human Landing System contract for the Starship-derived lander that will put astronauts on the surface under Artemis IV, currently targeting 2028. Before that can happen, SpaceX must demonstrate in-orbit propellant transfer at scale, a process requiring multiple Starship tanker launches to fuel a single mission. Water ice at the lunar south pole is central to the base’s long-term viability, as it can be converted into drinking water, breathable oxygen, and rocket fuel, directly reducing dependence on Earth resupply. That resource loop becomes far more practical if Starship can land and be refueled on or near the Moon itself.
Elon Musk has publicly stated that Starship V3, which recently completed its first flight, should be capable enough for initial Mars missions. The Moon Base plan announced Tuesday is the infrastructure layer that connects everything between those two ambitions, and SpaceX is the only American company currently contracted to build the rocket that gets humans to either destination.
A new Tesla patent that has been granted to the company this week has revealed a potential strategy for solving a major issue that could impact both the Full Self-Driving suite and Optimus.
The patent, which is No. 12,636,684, describes a “Lens Cleaning System,” and was submitted by Tesla in May 2025.
The language in the patent details a lens cleaning system that can dispense fluid and wipe it away with a wiper assembly.

This would effectively clean any debris that would potentially impact the visibility of the cameras on Tesla automobiles or Optimus’s camera eyes. Perhaps the most pertinent example is through the Full Self-Driving suite, as debris that can accumulate on the vehicle’s exterior cameras can impact the suite’s ability to operate effectively.
This requires a remedy through manual cleaning, but this patent hints that Tesla could be planning to implement this new technology on its upcoming vehicles.
Interestingly, we have started to see it on some Robotaxi vehicles, and it will likely be included in the Cybercab, especially as that vehicle will enable full autonomy.
Back in January, the first Model Y Robotaxi units were spotted with camera washers on the side repeaters, as the video below shows fluid squirting and rinsing off any debris that is limiting visibility.

This hardware patent does bring up an interesting question for those of us who own Teslas with AI4 and have been told that our cars will one day be capable of full autonomy: Will this washer be available as a retrofit on already-built cars?
Perhaps the “Lens Cleaning System” patent is a good look at one way Tesla plans to combat one of the most obvious issues of autonomy that utilizes a camera-based system. For Optimus, it could be less needed as it could be manually cleaned by owners. For cars, it seems like a bigger necessity, especially as autonomy nears and Tesla gets close to launching a feature-complete FSD suite.
SpaceX’s Starlink product has just gotten its latest airline adoptee, and the move marks the successful partnership of three of the “Big Four” U.S. airlines.
American Airlines announced on Tuesday that it would utilize Starlink in more than 500 narrowbody aircraft beginning in the first quarter of 2027. These include the Airbus aircraft in its fleet, including the new A321XLR and A321neo.
With the new partnership with American Airlines, Starlink is now present on three of the largest airlines in the country: American, United, and Southwest.
Starlink gets its latest airline adoptee for stable and reliable internet access
Starlink’s VP of Enterprise Sales, Jason Fritch, said:
“We are proud to bring Starlink on board American Airlines, delivering fast and reliable internet to passengers and crew. Whether traveling for leisure or business, Starlink enables a fully connected experience gate to gate, making every flight smoother and more enjoyable.”
Additionally, American Airlines Chief Customer Officer, Heather Garboden, said:
“As a premium global airline, we are continuously seeking out world-class partners like Starlink to deliver what our customers need and want. The addition of Starlink solidifies American as a leading airline in keeping passengers connected in flight.”
Starlink has been on a tear over the past year, as it has continued to be adopted by a wide variety of airlines as a more consistent and reliable way to provide WiFi to its passengers. It has already gained a great reputation among residential users, but its biggest commercial application appears to be how it is being used in the air.

The only airline of the Big Four not to adopt Starlink thus far is Delta, which chose to opt for the alternative, which is Amazon Leo. CEO Ed Bastian said to Bloomberg that Delta chose Amazon’s product over Starlink’s because “the opportunities, in terms of the improved bandwidth with a much lower price point than what we’ve ever seen from Starlink, will make a big difference.”
Delta will not start installing Amazon Leo until 2028.
“Of course, we expect Starlink will be warning people that we’re going to go with an inferior product,” Bastian said. “But I’m not too worried about partnering with Amazon.”
