An 11-way, 1,000-mile endurance test has proven that long trips with an electric vehicle in the United States are now possible, though those who are not driving Teslas may find themselves a bit challenged. These were the findings of motoring publication Car and Driver, which held a long-distance race between 11 EVs that are currently sold in the United States. 

The vehicles that participated in the test were the Tesla Model S Long Range Plus, Tesla Model Y Performance, Tesla Model 3 Performance, Ford Mustang Mach-E, Porsche Taycan 4S, Kia Niro EV, Audi e-tron, Volkswagen ID.4, Volvo XC40 Recharge, Polestar 2, and Nissan Leaf Plus. Participants in the event, which were comprised of two-person teams, were given free rein to select their own route, provided that they hit checkpoints in Cincinnati; Athens, Ohio; Morgantown, West Virginia; Erie, Pennsylvania; and Ann Arbor. 

Despite using apps like A Better Route Planner (ABRP), some teams immediately started hitting some challenges just a couple of dozen miles into the race. The team in the Nissan Leaf Plus, for example, made its first stop at a charging station just 23 miles into the race, reportedly as suggested by the ABRP app, but this resulted in them being the last group to arrive at a single ChargePoint DC fast charger in Lima, Ohio, behind three other teams. The team in the Audi e-tron eventually gave up their spot in the queue to look for another charging station, but they eventually returned after the other charger they were hoping to use turned out to be offline. 

The non-Tesla EVs with longer range such as the Ford Mustang Mach-E and the Volkswagen ID.4 fared slightly better, driving longer distances before needing a charge. When the vehicles did need a charge, however, the teams ended up experiencing similar issues as their competitors. From single ChargePoint DC fast chargers in some locations to areas with only Level 2 chargers available, some of the teams in the race ended up wasting valuable time. This was especially true for the Ford Mustang Mach-E team, whose lead against its non-Tesla peers tricked down as slowly as the Level 2 stations it ended up using north of Morgan­town. 

In comparison, the Tesla Model S, Model 3, and Model Y teams went through the race without much issues, and a good reason for this was the Supercharger Network. With the rapid charging station being as robust as it is today, the trifecta of Teslas dominated the 1,000-mile race. The Model S Long Range completed the race in commanding fashion, and it was followed by the Model Y team, who beat the Model 3 team through some extra assertiveness. This all but proved that if drivers wish to conduct long road trips in an electric vehicle today, Teslas are still the way to go. The Supercharger Network is just that good.

Ultimately, the Tesla Model S completed the 1,000-mile run in 16:14, followed by the Tesla Model Y, which finished the race in 17:50. The Tesla Model 3 took third place with a 17:55 time. The rest of the competition arrived over the following hours. The Ford Mustang Mach-E, the electric vehicle hailed by Car and Driver as its 2021 EV of the Year, came in at fourth place with a total time of 20:31, followed by the Porsche Taycan 4S, which had a total time of 21:00. The Kia Niro EV, the Audi e-tron, and the Volkswagen ID.4 all took over 23 hours to complete the 1,000-mile run, and the Volvo XC40 Recharge needed 25:47 to finish the race. The Polestar 2 took a surprisingly long 26:52 to complete its run, while the Nissan Leaf Plus took a whopping 32:57 before it crossed the finish line.

xAI receives more Tesla Megapacks for Colossus 2

Published

on

xAI is bolstering its Colossus 2 data center in Memphis with 168 Tesla Megapacks, enhancing the energy infrastructure for its ambitious AI supercomputer expansion. The deployment underscores xAI’s push to lead AI innovation while addressing environmental concerns.

The first Colossus site is connected to a 150 megawatts (MW) substation powered by MLGW and TVA. It is supported by approximately 156 Megapacks, providing 150 MW of stored energy backup to xAI’s supercomputer. The 168 Tesla Megapacks recently delivered to xAI’s Memphis site will provide battery storage backup to Colossus 2.

In December 2024, xAI doubled the capacity of Colossus to 200,000 Nvidia H100 GPUs, which consumes 250 MW of power–enough to energize 250,000 homes. In March 2025, the AI company bought a 1-million-square-foot site in Whitehaven, Memphis, for $80 million. xAI’s Whitehaven site could host up to 350,000 GPUs with the potential to deploy the largest number of Tesla Megapacks for backup power.

xAI plans to scale Colossus up to 1 million GPUs to create the world’s largest AI supercomputer. A 1-million-GPU setup would require over 1 gigawatt, about one-third of Memphis’s peak summer demand.

Initially reliant on natural gas turbines, Colossus faced criticism for nitrogen oxide emissions. The 150 MW substation, completed in early 2025, reduced turbine use by half, with Megapacks providing cleaner backup power. By fall 2025, xAI expects the second substation to come online. Once the second substation is online, the remaining turbines will only be used for backup, reducing the project’s carbon footprint.

Tesla Energy’s Q1 2025 performance, with a 156% year-over-year increase and 10.4 GWh of storage deployed, supports xAI’s needs. Tesla’s Megapack factory in Waller County, Texas, set to create 1,500 jobs, signals further commitment to scaling energy solutions for projects like Colossus.

xAI’s rapid expansion, backed by Tesla Megapacks, positions it to rival AI leaders like OpenAI and Google. The Colossus 2 deployment reflects a strategic blend of cutting-edge AI and sustainable energy. As Memphis’ infrastructure adapts to unprecedented power demands, xAI and Tesla are reshaping the AI landscape with a focus on efficiency and environmental responsibility.

Tesla Robotaxi deemed a total failure by media — even though it hasn’t been released

Nearly two weeks before it is even set for its planned rollout, Tesla Robotaxi has already been deemed a failure — even though it is not even publicly released.

Tesla Robotaxi is among the biggest tech developments of the year, and its June launch date has not yet arrived.

This does not matter to skeptics of the company, as they have already deemed the rollout a “failure,” “an enormous mess,” and plenty of other adjectives. No matter what, several outlets are already leaning on biased opinions and a lack of true evidence that points in any direction.

Futurism posted an article this morning claiming that Robotaxi is “already an enormous mess,” citing the opinions of Dan O’Dowd, perhaps Full Self-Driving’s biggest critic. There is no mention of any of the excitement or prosperity that would come from the opposite side of the argument.

Instead, it included that O’Dowd felt it was a failure in an 80-minute drive around Santa Barbara.

This is fair to include: Full Self-Driving is not perfect, which is why Tesla will implement safeguards like teleoperation at first. However, it’s not like it’s so awful it isn’t even remotely close. Personally, my experience with FSD was incredibly successful, responsible, and it was something I still wish I had on my car to this day. I wish the article would have included a quote from someone who is as equally passionate about FSD, just from the other side of the argument.

There is no mention of Tesla’s most recent Vehicle Safety Report, which showed Autopilot-enabled cars are nearly 10x less likely to be involved in an accident compared to the national average. This might not be the same as Full Self-Driving, but it is still a testament to what Tesla has achieved with its driver assistance systems.

To be fair, Tesla has been a company that has missed timelines, especially when it comes to FSD. I used to roll my eyes a bit when CEO Elon Musk would say, “We’ll have Full Self-Driving finished by the end of the year,” or “We’ll have a million robotaxis on the road next year.” I was always skeptical.

However, Tesla has handled things differently this year. They’ve admitted the Robotaxi rollout will be controlled at first, including a fleet of only 10-20 Model Y vehicles. It will be private at launch, and only the lucky invited will have the opportunity to experience it in Austin in June.

It might be less than a public rollout, which of course, for people like you and me, is disappointing. But let’s be real: if Tesla launched a full-blown Robotaxi platform with no regulations or small-batch testing, there would be criticism of that, too.

Some media outlets are pointing to the recent NHTSA request for more information on how Tesla’s tech will “assess the ability of Tesla’s system to react appropriately to reduced roadway visibility conditions.” This seems more than reasonable as Robotaxi will be among the first driverless ridesharing programs in the United States.

Tesla gets new information request from NHTSA on Robotaxi rollout

It’s no more than a request for information on how things will be handled and how the tech works.

It is sad to see so many outlets already deem something that could be the next big thing as a failure, despite there being no real indication of it being that or a success. Let’s be fair and give Tesla an opportunity to meet its June target and Robotaxi some time to operate and prove to be a reliable ride-share option.
