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.”

Tesla Giga Berlin is sending a strong message of solidarity amid its ongoing legal dispute with German union IG Metall.

In a post on social media platform X, Giga Berlin plant manager André Thierig shared an image of the facility’s lobby covered with a large banner that reads: “Progress. Innovation. Success.” He added that the slogan reflects what the facility has stood for since Day One.

“Our lobby at Giga Berlin covered in a huge banner these days. Progress. Innovation. Success – this is what we stand for since we started production in 2022 and how we will go into our future!” Thierig wrote in his post on X.

The dispute began after Tesla accused a union representative of secretly recording a works council meeting at Giga Berlin. Tesla stated that it filed a criminal complaint after the alleged incident. Police later confirmed they had seized a computer belonging to an IG Metall member as part of their investigation.

“What has happened today at Giga Berlin is truly beyond words! An external union representative from IG Metall attended a works council meeting. For unknown reasons he recorded the internal meeting and was caught in action! We obviously called police and filed a criminal complaint!” Thierig wrote on X at the time

IG Metall denied the accusation and characterized Tesla’s move as an election tactic ahead of upcoming works council elections. The union subsequently filed a defamation complaint against Thierig. Authorities later confirmed that an investigation had been opened in connection with the matter.

Giga Berlin began production in 2022 and has since become one of Tesla’s key European manufacturing hubs, producing the Model Y, the company’s best-selling vehicle. The facility has expanded capacity over the past years despite environmental protests, labor disputes, and regulatory scrutiny.

Tesla’s planned Megapack factory in Brookshire, Texas has taken a significant step forward, as two massive industrial buildings fully leased to the company were sold to an institutional investor.

In a press release, Stream Realty Partners announced the sale of Buildings 9 and 10 at the Empire West industrial park, which total 1,655,523 square feet. The properties are 100% leased to Tesla under a long-term agreement and were acquired by BGO on behalf of an institutional investor.

The two facilities, located at 100 Empire Boulevard in Brookshire, Texas, will serve as Tesla’s new Megafactory dedicated to manufacturing Megapack battery systems.

According to local filings previously reported, Tesla plans to invest nearly $200 million into the site. The investment includes approximately $44 million in facility upgrades such as electrical, utility, and HVAC improvements, along with roughly $150 million in manufacturing equipment.

Building 9, spanning roughly 1 million square feet, will function as the primary manufacturing floor where Megapacks are assembled. Building 10, covering approximately 600,000 square feet, will be dedicated to warehousing and logistics operations, supporting storage and distribution of completed battery systems.

Waller County Commissioners have approved a 10-year tax abatement agreement with Tesla, offering up to a 60% property-tax reduction if the company meets hiring and investment targets. Tesla has committed to employing at least 375 people by the end of 2026, increasing to 1,500 by the end of 2028, as noted in an Austin County News Online report.

The Brookshire Megafactory will complement Tesla’s Lathrop Megafactory in California and expand U.S. production capacity for the utility-scale energy storage unit. Megapacks are designed to support grid stabilization and renewable-energy integration, a segment that has become one of Tesla’s fastest-growing businesses.

Tesla Sweden strikers see tax issues over IF Metall union error

To address the issue, IF Metall is encouraging Tesla strikers to return the refunded tax amounts to the union.

A tax correction is set to return two years of income tax payments to Tesla strikers in Sweden, after authorities determined that conflict compensation during a labor dispute should not have been taxed.

The issue is caused by a decision by IF Metall to treat strike compensation for Tesla workers as taxable income during the ongoing labor dispute with Tesla Sweden. That approach has now been reversed following guidance from the Swedish Tax Agency.

Strike compensation is typically tax-free under Sweden’s Income Tax Act, as noted in a report from Dagens Arbete (DA). However, two years ago, IF Metall’s board decided to classify payments to Tesla strikers as taxable.

“We did it to secure SGI, unemployment insurance and public pension. Those were the risks we saw when the strike had already dragged on,” Kent Bursjöö, financial manager at IF Metall, stated.

According to Bursjöö, the union wanted to ensure that members continued to register earned income with the tax agency, protecting benefits tied to income history. At the end of January, however, the Swedish Tax Agency informed the union that compensation during a labor dispute must be tax-free.

“Of course, we knew that it could be tax-free. But we clearly didn’t know that it couldn’t be taxable,” Bursjöö said.

Following discussions with auditors and tax authorities, IF Metall began correcting the payments. As a result, two years of paid income tax will now be credited back to the affected strikers’ tax accounts. The union will also recover previously paid employer contributions.

However, the correction creates secondary effects. Since the payments will now be treated as tax-free, pension contributions tied to those earnings will be withdrawn, potentially affecting state pension accrual and income-based benefits such as parental or sickness benefits.

To address this, IF Metall is encouraging members to return the refunded tax amounts to the union. In exchange, the union plans to pay 18.5% into occupational pensions on their behalf. “Otherwise, it will be a form of overcompensation when they get the tax paid back,” Bursjöö said.

That being said, the IF Metall officer acknowledged that the union’s legal ability to reclaim the funds from its improperly paid Tesla Sweden strikers is limited. “The legal possibilities are probably limited, from what we can see. But we assume that most people see the value of securing their pension,” Bursjöö said.
