Rivian patent hints at real-time brake wear monitoring system using driver profiles

Rivian’s attention to detail on its all-electric vehicles is laudable, and a recent patent application by the outdoor adventure company for monitoring brake wear continues that theme. In an application titled “Methods, Systems, and Media for Non-Contact Brake Pad Wear Determination”, a method of estimating the wear on individual breaks via computer algorithms is described. Once calculated, the information is then made available to drivers for planning purposes via the infotainment screen on the R1T pickup truck and R1S SUV. The application published on August 1, 2019 under US Patent Publication No. 2019/0234475.

The background of Rivian’s application stated the following reasons why the invention is needed:

“Current approaches for determining brake pad wear…tend to merely indicate when brake pads are fully worn, for example, using a brake pad indicator that causes the brakes to squeal when the indicator contacts the brake disc or that causes an indication on a dashboard of the vehicle to be presented. It may be useful for a driver to know a current wear condition of the brake pads before the brake pads are fully worn, for example, to plan for vehicle maintenance. However, it can be difficult to determine a current wear of the brake pads.”

While not an official reason listed on the patent, one could also assume brake squealing as an annoying sound in itself would also merit the invention’s usefulness as a reliable preventative.

Overall, Rivian’s application calculates the amount of wear on its vehicles’ brakes by comparing data points gathered from two braking events. The amount of pressure applied plus the distance traveled at two different intervals is collected, then compared to a brake database, and an estimate of the mileage left before a change is needed is provided to the driver. The calculation can also include the driver’s braking history to more accurately reflect the mileage. In other words, if you’re a bit rough on the brake pedal, Rivian’s software will take that into account and probably shorten the mileage you have left before needing replacement parts compared to someone that drives…differently. Here’s the formal language for this ability:

“In some embodiments, the method further comprises associating a braking profile with an operator of the vehicle, wherein the indication of the wear amount of the brake pad includes a number of miles until the brake pad requires replacement that is estimated based on the associated braking profile.”

The method described in the claims of the application that calculate the wear on the brakes indicates a process initiated by the driver, i.e., the driver initiates a brake wear test on the center touchscreen and uses the brakes at two intervals as instructed by the vehicle’s computer to determine the wear percentage. However, the description of the application indicates that the brake testing can also happen in real-time during normal operation. The formal language for this reads as follows:

“…In some embodiments, [the testing] process…can receive a group of brake caliper measurements and corresponding brake pedal travel distances…during application of the brake pedal during normal operation of the vehicle…Additionally, in some such embodiments, [the testing] process can present indications of brake pad wear at any suitable time, such as a next time the vehicle is turned on, and/or at any other suitable time.”

This application is yet the latest nod towards Rivian’s development of a comfortable and luxury driving experience for its vehicle owners. The car maker’s branding as an outdoor electric adventure company really seems to have embraced its mission to get people outside exploring more by making the experience as convenient as possible. Whether it’s ample storage capacity, swapping out cargo modules, extending battery range with a digital jerry can, a portable kitchen built specifically for the R1T pickup truck, or now, being able to easily plan ahead for basic vehicle maintenance by checking a screen, Rivian is continuing its march against barriers to enjoying nature anywhere.

There’s a new phrase that seems to be developing based off of an old one about willpower: “Where there’s a Rivian, there’s a way.”

Accidental computer geek, fascinated by most history and the multiplanetary future on its way. Quite keen on the democratization of space. | It's pronounced day-sha, but I answer to almost any variation thereof.

Tesla has launched another new affordable Model Y configuration in the United States, now adding a fifth version of the all-electric crossover to its lineup, diversifying the car’s options and giving consumers more choices at the time of purchase.

Tesla launched the Model Y All-Wheel-Drive on Monday night, pricing it at $41,990. It features 294 miles of range, a 125 MPH top speed, and a 0-60 MPH acceleration rate of 4.6 seconds.

The vehicle is the second most-affordable configuration of the Model Y, only eclipsing the Model Y Rear-Wheel-Drive, which is priced at $39,990.

The move to expand the Model Y lineup comes just a week after CEO Elon Musk confirmed the company would remove the Model S and Model X from production, making way for manufacturing of the Optimus robot at the company’s Fremont, California, factory.

The Model Y All-Wheel-Drive fits the bill of the “Standard” offerings of the vehicle that Tesla launched last year. It is void of many of the more luxurious features, which are available in the “Premium” trim levels, available in Rear-Wheel-Drive, All-Wheel-Drive, and Performance.

With five configurations now available in the Model Y, it certainly seems as if Tesla is attempting to get the vehicle available in more options than ever before.

With the Model S and Model X being removed from production due to their irrelevance to the future and Tesla’s focus on autonomy, diversifying the Model Y portfolio seems to align with the idea that the company is okay with making more variations of its most popular car.

Removing the Model S and Model X and replacing them with a new Model Y configuration is not exactly what fans have been wanting; many have been wondering what Tesla will do to replace the need for a bigger SUV for large families.

Nevertheless, Tesla’s relentless attitude toward solving autonomy and its preparation to launch a self-driving ride-hailing service seem to fit the bill for this move. Soon, it will be the Model 3, Model Y, and Cybercab playing the main parts of this autonomous future. The Cybertruck will be sticking around for other things, like local hauling.

SpaceX has officially acquired xAI, merging rockets with AI expertise in what is the first move to bring Elon Musk’s companies under one umbrella.

On February 2, SpaceX officially announced the acquisition of xAI, uniting two powerhouse companies under a single entity, creating what the space exploration company called in a blog post “one of the most ambitious, vertically integrated innovation engines on (and off) Earth.”

The deal will integrate xAI’s advanced AI capabilities, including the Grok chatbot and massive training infrastructure, with SpaceX’s rocket technology, Starlink satellite network, and ambitious space exploration goals.

The acquisition comes at a pivotal moment: xAI is valued at around $230 billion as of late 2025, and has been racing to scale AI compute amid global competition from companies like OpenAI, Google, and Meta. Meanwhile, SpaceX, which was recently valued at $800 billion, is facing escalating costs for its multiplanetary ambitions.

SpaceX-xAI merger discussions in advanced stage: report

By combining forces, the merged entity gains a unified approach to tackle one of AI’s biggest bottlenecks: the enormous energy and infrastructure demands of next-gen models.

Musk wrote in a blog post on SpaceX’s website that:

“In the long term, space-based AI is obviously the only way to scale. To harness even a millionth of our Sun’s energy would require over a million times more energy than our civilization currently uses! The only logical solution therefore is to transport these resource-intensive efforts to a location with vast power and space. I mean, space is called “space” for a reason.”

Musk details the need for orbital data centers, stating that his estimate is that “within 2 to 3 years, the lowest cost way to generate AI compute will be in space.

This cost-efficiency alone will enable innovative companies to forge ahead in training their AI models and processing data at unprecedented speeds and scales, accelerating breakthroughs in our understanding of physics and invention of technologies to benefit humanity.”

SpaceX recently filed for approval from the FCC to launch up to one million solar-powered satellites configured as high-bandwidth, optically linked compute platforms.

These facilities would harness near-constant sunlight with minimal maintenance, delivering what the company projects as transformative efficiency.

Musk has long argued that space offers the ultimate solution for power-hungry AI projects. But that’s not all the merger will take care of.

Additionally, it positions the company to fund broader goals. Revenue from the Starlink expansion, potential SpaceX IPO, and AI-driven applications could accelerate the development of lunar bases, as Musk believes multiplanetary life will be crucial to saving civilization.

Critics question the feasibility of massive constellations amid orbital debris concerns and regulatory hurdles. Yet, proponents see it as a bold step toward a multiplanetary computing infrastructure that extends human civilization beyond Earth.

Tesla Model Y Performance Review: The Best Trim of the Best Vehicle?

Published

on

Credit: Tesla

The Tesla Model Y Performance was in my hands for seven days after the company reached out and got me a brand new unit. As a Premium All-Wheel-Drive owner, I was really interested to see if the Performance trim was worth the $11,000 difference, and what I learned might be a surprise.

The only “performance” version of any Tesla vehicle I’ve had the opportunity to have several days with was the Cyberbeast back in June, and a few days with that made me want a Cybertruck more than I already did. It had white-knuckle speed, and as someone who truly loves to drive a larger vehicle, it fit the bill for everything I wanted out of an electric pickup.

With that past experience, I was truly excited to try the new Model Y Performance, especially considering I own a Model Y already, and after six months of ownership, it has truly won me over as the best car I’ve ever owned. Although my 2008 Ford Escape Hybrid is a close second, mostly due to nostalgia and it being my “dream car” as a kid in high school at the time, the Model Y is unequivocally better, obviously. It’s hard to shake the feelings of your first “nice” car; I think we could all relate to that in a way.

Before I even picked up the Model Y Performance, I was expecting a handful of things: better performance, better handling, more comfortable seats, and a thirst for spirited driving on the windy backroads of Southern Pennsylvania. Admittedly, a snowstorm disrupted a lot of my testing, but I was still able to have some fun in the car.

With that being said, my thoughts are sure to potentially ruffle some feathers.

First Impressions of the Tesla Model Y Performance

I picked up the Model Y Performance on January 19 and had it for one week. The Ultra Red paint with the White interior option was a great look, and it was fun to have a car with that look, considering my Model Y is Black on Black.

One thing that is really interesting and somewhat surprising is that Tesla hasn’t adjusted the fact that the Ultra Red is a different shade than the Performance brake calipers. Additionally, the rear light bar, which signals braking, is a different shade of red than the car and the brake calipers.

This was something that the Tesla Showroom employees pointed out to me, and, just like they said, I’ll never be able to not see it.

Interior Quality

The first thing I noticed was the Performance seats, which are geared to hug you a tad more and keep you intact during spirited drives. They were, without a doubt, more comfortable than the seats in my Premium AWD.

Interestingly, when I gave this opinion on X, some Performance owners said that the seats were less comfortable and, on longer drives, I’d feel it. My Fiancè and I drove about 120 miles in the car that weekend, and we had no complaints. They were supremely comfortable, and we both really enjoyed them, almost to the point that we’d rather have those seats than the ones in the Premium AWD.

Additionally, the center screen is slightly larger, but not to the extent that I had really noticed any true difference. In the new Model Y for 2026, the screen is the same size as the one in the Performance trim at 16 inches.

It was previously 15.4 inches.

Some other changes include Performance pedals that are made of what appears to be a stainless steel alloy and Carbon Fiber accents on the doors and dash. Other than that, there are no significant differences; it’s very similar to the other Premium trims of the Model Y. The big difference from an interior standpoint is simply the front seats.

Exterior Differences

Tesla used a lot of different techniques to help improve performance and aerodynamics, including a carbon fiber spoiler and rear diffuser, both of which help with air displacement and improve handling, range, and overall performance.

These additions are clean and give the car a sporty look, perfectly catered to the aesthetic Tesla was obviously going for with the car. I’ve already mentioned the brake calipers, which are an awesome touch, but the offsetting tones of red between them and the paint are a bit displeasing to the eye. I hope this is something that is resolved, but it isn’t completely necessary, nor a priority.

The Nitty Gritty – Ride Quality and Performance

With all the changes from an aesthetic standpoint, including the ones that are geared toward improving performance, the real indicator of whether this trim is worth the extra $11,000 is simple: Is it faster and more fun to drive than the Premium All-Wheel-Drive?

I’m going to break that down here:

Speed and Acceleration

There is a slightly noticeable difference in acceleration, as the 4.6-second 0-60 MPH on the AWD is 1.3 seconds slower than the 3.3-second rate on the Performance. Although that sounds like a decent difference, the big change I noticed was the sound. In the Performance, you can really hear those motors hum, which was a nice touch and really interesting and fun to experience.

It was definitely quicker than my AWD, but I think I really expected to be thrown back into my seat like I was with the Cyberbeast, which features a 2.6-second 0-60 MPH acceleration rate. That was truly a massive difference that anyone can really feel. The 1.3-second difference between the AWD and Performance was, in a way, underwhelming.

I was not disappointed with it, but I really hoped to feel that same rush of adrenaline I had with the Cyberbeast. I think I’m just so used to the acceleration at this point that it does not “wow” me any longer. At the time of the Cyberbeast Demo Drive, I was still driving a gas car.

The Performance, like the AWD, is very capable. It’s great for merging on the highway and getting into a tight window when traffic is heavier. It’s great for taking some quicker drives, and it’s a lot of fun to take out on the road. By no means am I disappointed with it, but I will say maybe my expectations were a tad too high.

Handling

This is where I will say I was sort of disappointed, because I have heard from many people that the suspension is better in the Model Y Performance compared to the All-Wheel-Drive.

I didn’t really feel like it was “better,” but the same, which is still an absolutely amazing ride experience. My AWD is great for tight turns at increased speeds, where I felt the difference was in the seats, as those Performance ones truly did seem to “hug” me more and keep me more stable.

The Performance trim features adaptive suspension, lower/stiffer springs, and larger wheels, all of which are meant to improve handling. I’m not sure if it is simply because I didn’t get to push it as much as I wanted to due to weather, but I felt like the feel of the ride was really similar to my AWD. I had no complaints.

Overall Thoughts

The Model Y Performance is definitely a sportier look than the AWD and Standard models, and it definitely has its advantages. I think that it’s a really great car, but I did not feel an incredible number of differences from the AWD.

There was a lot to love: the seats, the look, the acceleration. The latter is something that is definitely great if you plan to take your car to a track, but for public roads, it’s not something that is a substantial “need.” When I pushed it on a road local to me and posted a video of it, the commenters were sure to tell me I was going too fast.

I want to be clear that I have zero complaints about the Model Y Performance, and if it were to have come out ahead of me getting my AWD, I probably would have entertained the idea if I could have made the numbers work.

The Model Y, from Standard to Premium, is a great car in every sense of the word. The ride quality is great, the build quality is excellent, and the interior and exterior features, as a whole, make it the best car in the world (to me).
