How does Tesla ‘Ludicrous Speed’ work?

Published

on

Following the announcement that Tesla will be releasing a ‘Ludicrous Speed’ upgrade for the dual-motor Model S P85D and upcoming Model X, the natural question emerged: How does Tesla Ludicrous Speed work?

How was Tesla able to extract more acceleration from the already ‘Insane'(ly) quick Model S P85D, and from the same battery back?

It’s important to first understand that the Model S uses an inverter to convert the transfer of electrons from Tesla’s direct current (DC) battery back to alternating current (AC) of the electric motor. Quoting an analogy provided by ExplainThatStuff, we learn that the electrons work like a line of ants, marching along with packets of electrical energy in the same way that ants carry leaves. The more ants we have, theoretically, the more packets of electrical energy we’ll have.

Citing our friends at TeslaTap, current flowing from the battery passes through a contactor which is a large switch controlled by an electromagnet under software control. The contactor connects the battery pack from connections outside the pack such as to the motor inverter, chargers, etc.

The algorithms within Tesla’s Firmware helps maintain constant torque by controlling the amount of current flowing through the contactors and to the electric motors. Ludicrous Speed adds a safety fuse and a new type of contactor that can safely sustain a current draw of 1,300 amps to 1,500 amps thereby allowing the electric motors to temporarily produce more power, and for a longer duration of time. End result? Mind-shattering acceleration to the tune of 0-60 mph in 2.8 seconds.

While working on our goal of making the power train last a million miles, we came up with the idea for an advanced smart fuse for the battery. Instead of a standard fuse that just melts past a certain amperage, requiring a big gap between the normal operating current and max current, we developed a fuse with its own electronics and a tiny lithium-ion battery. It constantly monitors current at the millisecond level and is pyro-actuated to cut power with extreme precision and certainty.

That was combined with upgrading the main pack contactor to use inconel (a high temperature space-grade superalloy) instead of steel, so that it remains springy under the heat of heavy current. The net result is that we can safely increase the max pack output from 1300 to 1500 Amps.

Tesla launches new color from Gigafactory Berlin

Tesla has launched a new color at Gigafactory Berlin in Germany, home of the company’s “world-class paint shop,” as Elon Musk once called it.

Bringing a new color to Tesla’s Model Y, there are now five available colors for those who will receive a vehicle from Gigafactory Berlin, with four of them being colors offered in other markets.

However, there is now one distinct color that is only available in Germany: Marine Blue.

Priced at €1,300, Marine Blue will cost the same as both Diamond Black and Stealth Grey, while Quicksilver and Ultra Red are available for double the price.

It is the third shade of blue Tesla offers across its lineup, as Deep Metallic Blue and Glacier Blue are also offered, but in other markets.

Tesla has routinely flexed Giga Berlin for having the most advanced paint shop throughout its factories, and it has produced some interesting colors over the past few years, some of which were truly awesome.

In 2020, Musk said, “Giga Berlin will have the world’s most advanced paint shop, with more layers of stunning colors that subtly change with curvature.”

He also detailed the company’s plans to upgrade the Fremont and Shanghai paint shops. Gigafactory Texas was not yet unveiled. Tesla has worked to improve those facilities, especially in Fremont.

It was able to roll out the new Diamond Black color earlier this year.

However, Giga Berlin seems to remain the standard in terms of paint for Tesla. It routinely offers new colors.

For example, back in 2022, Tesla rolled out its familiar Quicksilver color for the Model Y, while also introducing Midnight Cherry Red, a color close to burgundy. However, the company chose to discontinue the color after determining internally that customers no longer wanted to buy it.

Midnight Cherry Red was removed as an option earlier this year, likely to make way for the development of the new Marine Blue.

Tesla Autopilot visualization gets big upgrade with tons of new additions

Tesla’s Autopilot visualization just got a big upgrade as the company added tons of new additions to what it will be able to render in terms of a vehicle’s surroundings.

The AP visualization shows up on the center touchscreen and illustrates the surroundings of the cars. It has gotten better in recent years, as it is able to outline types of vehicles, pedestrians, animals, and more.

Tesla just fixed a four-year-old bug with Full Self-Driving visualization

However, it still does not have every single application, and acquiring them will take some time. If an object or vehicle is visible to the vehicle but an accurate render is not available, the car will instead pick whatever is closest.

For example, I passed an Amish family yesterday in Lancaster, PA, and instead of illustrating the horse and carriage, it simply showed a small box truck.

In an effort to make the Autopilot and Full Self-Driving suites more robust and accurate, Tesla has added a substantial amount of vehicle renders, which will become available in the coming weeks.

The visualizations were found by Tesla hacker @greentheonly, who posted them on X.

The new visualization renders are:

  • Ambulance
  • Firetruck
  • Garbage Truck
  • Schoolbus
  • European Semi Truck
  • Golf Cart
  • Person on a Scooter
  • Person on a Skateboard
  • Stroller
  • Street Sweeper
  • Three-Wheeler
  • Trailer
  • Train
  • Tram
  • Person in a Wheelchair

Here is an image with all of the Autopilot visualization renders:

The visualization is a crucial part of manual operation and can be considered a distinct advantage that Tesla has over other companies.

It continues to be an effort that Tesla invests heavily in, as it keeps refining the suite and making it more robust with additional visualizations and animations.

Recently, it was revealed that Tesla is planning to utilize Unreal Engine for driver visualization to create a realistic depiction of the vehicle’s environment. Tesla has not yet confirmed this, but coding found with the Model S and Model X showed it could be coming in the near future.

Tesla dominates best-selling EVs in Q3, but there’s one disappointment

Published

Tesla dominated the sales figures for electric vehicles in the third quarter in the United States, but there was one disappointment: the Cybertruck.

As a whole, the EV industry benefitted from the loss of the $7,500 EV tax credit in Q3, which was something many expected. As the credit expired, consumers rushed to showrooms to take the credit and remove $7,500 from the purchase price of their new vehicle.

Will Tesla thrive without the EV tax credit? Five reasons why they might

It was a very interesting time for many companies as they scrambled to figure out how to push as many vehicles out the door as they could in preparation for the tax credit’s removal. In typical fashion, Tesla was able to top every manufacturer and secure a dominating portion of the overall market in Q3.

However, some other OEMs pulled out some surprises, including Chevrolet, Honda, and Ford, which managed to get two vehicles in the top 10, as many as Tesla.

Cox Automotive compiled the data in its Q3 Electric Vehicle Sales Report:

  1. Tesla Model Y – 114,897
  2. Tesla Model 3 – 53,857
  3. Chevrolet Equinox EV – 25,085
  4. Hyundai Ioniq 5 – 21,999
  5. Honda Prologue – 20,236
  6. Ford Mustang Mach-E – 20,177
  7. Volkswagen ID.4 – 12,470
  8. Audi Q6 e-tron – 10,299
  9. Ford F-150 Lightning – 10,005
  10. Rivian R1S – 8,184

10.5 percent of the automotive sales in the U.S. in Q3 were electric, a new record that surpasses that of Q3 2024, where the total share of sales for EVs was 8.6 percent.

Now, the disappointment that is evident from this list is the fact that there is no Tesla Cybertruck listed. That’s because it was the second-best-selling EV pickup on the market. The company sold 5,385 Cybertruck units in Q3.

The Cybertruck has been a vehicle that has confused many Tesla fans and owners, especially considering the company had such stratospheric expectations for the vehicle while it was in development. Reservation trackers had the truck sitting between one million and two million orders, but it has not lived up to that.

Pricing is the main issue with Cybertruck. Tesla introduced the pickup with Single, Dual, and Tri-motor configurations, priced at $39,990, $49,990, and $69,990. Those price points are simply a thing of the past.
