Porsche has stated that one of the Taycan’s primary characteristics will be its capability to be driven hard on the track. In order to do this, the upcoming all-electric four-door would have to be equipped with powerful motors, a well-balanced, hefty battery, and capable, high-performance wheels. It takes some serious rubber, after all, to ensure that the Taycan stays planted on the road when it’s ripping through a closed circuit. 

So far, Porsche has kept the Taycan’s tire size secret. Even the camouflaged prototypes of the vehicle that have been deployed across the globe and spotted in numerous countries have mostly been equipped with unmarked tires. Fortunately, St00k, a moderator at TaycanEVForum.com, was recently able to capture a rare image one of the Taycan’s wheels that just happens to be marked.  

What the TaycanEVForum.com moderator found was quite surprising. Looking at the Taycan prototypes that are being tested across the globe, it is easy to see that the all-electric vehicle is equipped with massive, wide tires.

As could be seen in the recently-shared photo, the Taycan prototype was equipped with 305/30/ZR21 Goodyear Eagle tires. That’s incredibly wide for a four-door sedan that’s the size of the Taycan, especially considering that the larger Tesla Model S P100D (now dubbed as the Model S Performance), only comes with 265/35/21 rear tires. 

These large, wide tires hint at serious track performance for the Taycan. Large wheels such as 305/30/ZR21s, after all, provide exceptional handling for the upcoming all-electric car. This is particularly important for the Taycan, considering that one of its key selling points is its capability to be driven hard for extended periods of time without losing power.

So far, the Tesla Model 3 Performance is the benchmark when it comes to electric four-door sedans that can handle track driving, thanks to its dedicated Track Mode. With this in mind, Porsche would have to dig deep to make sure that the Taycan, which is significantly more expensive than the Model 3 Performance, will feature closed circuit driving capabilities that justify its Model S-level price. 

While the Taycan’s 305/30/ZR21 tires confirm that the vehicle will be a monster around the track, the large tires also bring up some concerns about the vehicle’s range and efficiency. Larger, wider tires usually give optimum performance at the cost of range. This could be seen in the Model S, as a pre-“Raven” 100D equipped with 245/45/19 tires was listed with more range than a P100D fitted with 265/35/21 tires.

Hopefully, Porsche could balance the Taycan’s performance with its range well. This would allow the highly-anticipated vehicle to avoid the pitfalls of other premium EVs from European automakers such as Audi and Jaguar, both of whom have released otherwise great electric cars that are, unfortunately, the zero-emissions equivalent of gas-guzzlers.

Tesla reveals early Robotaxi charging strategy, showing scrappy DNA

Published

Tesla’s early strategy for charging units operating within its Robotaxi fleet reveals that the company surely has not lost any of that scrappy DNA that took it from an unlikely success story to the most valuable carmaker in the world.

An observer at a Tesla Supercharger in Austin spotted ten total Robotaxi vehicles arrive: one Cybercab and nine Model Y units. A Tesla employee was waiting at the lot and allowed each unit to park itself; every car that arrived had nobody in it.

Tesla wins FCC approval for wireless Cybercab charging system

The Tesla employee would walk around and plug each car in, adjusting the parking if needed:

It’s a very interesting strategy, but extremely understandable at this early point in the Robotaxi program. It’s only been out for about 15 months, and Cybercab just entered the fleet in early September.

On top of that, Tesla is still working tirelessly on its wireless charging apparatus, and a new patent was just published regarding that product last week.

However, this is just another example of how Tesla still has plenty of that scrappy DNA leftover from the “production hell” days, when CEO Elon Musk slept on the floor of the factory, employees were working crazy hours, Tesla was building Sprung Structures to build cars in, and the company was tiptoeing on the brink of bankruptcy.

For now, Tesla is utilizing a simple system for recharging its ride-hailing vehicles, and that is a Tesla employee doing it manually until another solution presents itself. Sure, it’s not the most high-tech thing, and it certainly is not what people might have expected at this point in time, but it works, and it’s keeping the entire suite running.

Tesla Robotaxi expands hours, Musk explains why it’s been a challenge

Published

Tesla is expanding its Robotaxi service hours by pushing the time back by one hour, keeping the ride-hailing service operational until 11 p.m., one hour later than previously.

CEO Elon Musk confirmed the change and offered a specific reason the expansion has been gradual: the system still needs to reliably avoid small pets that are difficult to see after dark, as they commonly blend into the color of the road, especially when they’re grey.

The latest adjustment restores only a fraction of the operating window the service once held. When paid Robotaxi rides began in Austin on June 22, 2025, vehicles ran from 6 a.m. to midnight.

Tesla Robotaxi will be a 24/7 service: here’s when

In September 2025, Tesla lengthened the day to a 2 a.m. close, producing a 20-hour window that stayed in place for most of the following year. By early August of this year, the cutoff had already been pulled back; an August 26 update formalized hours of 6 a.m. to 10 p.m. across Austin and several other markets.

The October move to 11 p.m. therefore leaves the Austin day one hour shorter than the original launch schedule and three hours shorter than the 2025 peak.

Musk addressed the constraint directly after the announcement. “The main thing we’re trying to solve is making sure that we don’t run over pets when they’re hard to see at night,” he wrote. “Literally trying to avoid grey kittens on grey tarmac in the dark.”

The example points to a low-contrast perception problem in which a small animal can blend into the road surface under limited lighting.

Tesla’s vehicles rely on cameras and neural-network processing rather than lidar; Musk has previously argued that advanced vision software can extract useful information even in low light by analyzing photon counts, but the pet-detection case remains the stated limiter in later hours.

The modest schedule change arrives alongside faster growth in the purpose-built Cybercab fleet. Texas registration data tracked by observers showed the Austin Cybercab count rising sharply in recent weeks, reaching 169 vehicles after more than 100 were added in a short span.

Tesla has indicated that a broader shift toward 24-hour operation is tied to the upcoming FSD v15 software release expected this month on Robotaxi vehicles. Until that capability is validated for the edge cases Musk described, the company continues to add service time incrementally rather than jumping straight to overnight coverage.

The one-hour extension gives Austin riders a later option for evening trips while the underlying detection work continues.

Tesla snags Semi supply deal with major logistics firm

Tesla has snagged a deal with IMC Logistics to supply the company with 50 Semi units for its logistics operations.

IMC handles drayage and landside logistics and has over 2,700 asset trucks in its fleet. In its over forty years of service, it has established more than 50 locations across the United States and spans operations from coast to coast.

Jim Gillis of IMC said that the addition of the Tesla Semi will help IMC move toward a “zero-emission service for long-haul lanes.”

The move is one that has become more common over the past few years, as more and more companies doing large-scale logistics have moved to sustainable powertrains, using either Tesla or others.

Tesla’s Semi program just entered its first truly public phase, as the company handed over its first production units to companies in September, although a pilot program with companies like PepsiCo. and Frito-Lay has been ongoing for years.

IMC announced its intention to purchase 50 Semi units from Tesla in September, and according to VP of Marketing and Public Relations on September 29 to Trucking Drive, the company will take delivery either this week or took delivery late last week.

Tesla has a ‘no human contact’ approach for Semi production

With surging prices of diesel and high logistics costs, Tesla and the Semi could truly revolutionize how companies manage their fleets. With the advent of Full Self-Driving, the Semi will potentially cut down on driver fatigue and increase productivity, while decreasing the cost of operation per mile by being cheaper to refuel.

Tesla had a dedicated Semi handover event at the Semi factory in Sparks, Nevada, a few weeks back, as it officially introduced its truck to many company fleets that have been waiting to add these sustainable powertrains.
