Being all-electric, Tesla’s vehicles enjoy a number of advantages. They have instant torque for quick acceleration runs, a low center of gravity for great handling, and large crumple zones for protection during a crash. Recent traction tests on metal rollers have also shown that the electric car maker’s Dual Motor AWD setup gives vehicles like the Model 3 some very impressive traction. 

It is pertinent then to see just how well Tesla’s Dual Motor AWD setup stacks up against one of the best 4×4 systems available today: Audi’s Quattro. The German automaker’s all-wheel-drive system has been around for nearly 40 years, and it was tempered and developed at a time when the Audi was competing in the 1980’s rally championships. Audi sedans with Quattro technology are known today as vehicles that can handle wet, slippery conditions without any issues. 

Compared to the long history of Audi’s Quattro, Tesla’s Dual Motor AWD is a newcomer. The electric car maker’s all-wheel-drive system made its debut on October 2014 with the Model S P85D, and it has received refinements since. Tesla’s Dual Motor AWD setup, just like Audi’s Quattro, gives the company’s vehicles, from the Model S to the Model X to the Model 3, notable traction even in slippery conditions. 

The capabilities of these two AWD systems was recently compared by YouTube group duszaniespokojna – 4×4 tests on rollers, which conducts traction tests on a variety of vehicles using rollers, from serious off-roaders like the Land Rover Discovery to sedans like the Tesla Model 3. For its comparative test, the YouTube group opted to use a Tesla Model 3 Dual Motor AWD and an Audi A4 Allroad 2.0 TFSI Quattro Ultra, both of which are midsize vehicles.

The Tesla Model 3 aced all of the group’s traction tests, both in its Standard and in Slip Start settings. Even when three of its wheels were in rollers, the electric sedan was able to find its traction without any issue. This is likely due to several factors, including the Model 3’s weight thanks to its hefty battery pack, as well as the instant torque from the vehicle’s two electric motors.

In comparison, the Audi A4 Allroad struggled in a couple of tests. While the vehicle had no issues finding its traction during tests that involved one or two rollers, the A4 had a notably difficult time when three of its wheels were fitted with rollers. When all but one rear wheel of the A4 Allroad was on rollers, the car actually got stuck when it was in its Standard setting.  

Tesla may be a new carmaker, but it is steadily gaining a reputation as one of the best, if not the best, maker of premium electric cars on the market. It should also be noted that the Model 3 Dual Motor AWD is designed for city driving, which makes its 4×4 performance even more impressive. It takes a great city car, after all, to beat Audi’s Quattro system at its own game.

When Elon Musk spoke with CNBC’s David Faber in an interview at Giga Texas, he reiterated the idea that Optimus will be one of Tesla’s biggest products. Seemingly to highlight the CEO’s point, the official Tesla Optimus account on social media platform X shared what could very well be the most impressive demonstration of the humanoid robot’s capabilities to date.

Optimus’ Newest Demonstration

In its recent video demonstration, the Tesla Optimus team featured the humanoid robot performing a variety of tasks. These include household chores such as throwing the trash, using a broom and a vacuum cleaner, tearing a paper towel, stirring a pot of food, opening a cabinet, and closing a curtain, among others. The video also featured Optimus picking up a Model X fore link and placing it on a dolly.

What was most notable in the Tesla Optimus team’s demonstration was the fact that the humanoid robot was able to complete all the tasks through a single neural network. The robot’s actions were also learned directly from Optimus being fed data from first-person videos of humans performing similar tasks. This system should pave the way for Optimus to learn and refine new skills quickly and reliably.

Tesla VP for Optimus Shares Insight

In a follow-up post on X, Tesla Vice President of Optimus (Tesla Bot) Milan Kovac stated that one of the team’s goals is to have Optimus learn straight from internet videos of humans performing tasks, including footage captured in third person or by random cameras.

“We recently had a significant breakthrough along that journey, and can now transfer a big chunk of the learning directly from human videos to the bots (1st person views for now). This allows us to bootstrap new tasks much faster compared to teleoperated bot data alone (heavier operationally).

“Many new skills are emerging through this process, are called for via natural language (voice/text), and are run by a single neural network on the bot (multi-tasking). Next: expand to 3rd person video transfer (aka random internet), and push reliability via self-play (RL) in the real-, and/or synthetic- (sim / world models) world,” Kovac wrote in his post on X.

Starship Flight 9 nears as SpaceX’s Starbase becomes a Texan City

SpaceX’s launch site is officially incorporated as Starbase, TX. Starship Flight 9 could launch on May 27, 2025.

SpaceX’s Starbase is officially incorporated as a city in Texas, aligning with preparations for Starship Flight 9. The newly formed city in Cameron County serves as the heart of SpaceX’s Starship program.

Starbase City spans 1.5 square miles, encompassing SpaceX’s launch facility and company-owned land. A near-unanimous vote by residents, who were mostly SpaceX employees, led to its incorporation. SpaceX’s Vice President of Test and Launch, Bobby Peden, was elected mayor of Starbase. The new Texas city also has two SpaceX employees as commissioners. All Starbase officials will serve two-year terms unless extended to four by voters.

As the new city takes shape, SpaceX is preparing for the Starship Flight 9 launch, which is tentatively scheduled for May 27, 2025, at 6:30 PM CDT from Starbase, Texas.

SpaceX secured Federal Aviation Administration (FAA) approval for up to 25 annual Starship and Super Heavy launches from the site. However, the FAA emphasized that “there are other licensing requirements still to be completed,” including policy, safety, and environmental reviews.

On May 15, the FAA noted SpaceX updated its launch license for Flight 9, but added: “SpaceX may not launch until the FAA either closes the Starship Flight 8 mishap investigation or makes a return to flight determination. The FAA is reviewing the mishap report SpaceX submitted on May 14.”

Proposed Texas legislation could empower Starbase officials to close local highways and restrict Boca Chica Beach access during launches. Cameron County Judge Eddie Trevino, Jr., opposes the Texas legislation, insisting beach access remain under county control. This tension highlights the balance between SpaceX’s ambitions and local interests.

Starbase’s incorporation strengthens SpaceX’s operational base as it gears up for Starship Flight 9, a critical step in its mission to revolutionize space travel. With growing infrastructure and regulatory hurdles in focus, Starbase is poised to become a cornerstone of SpaceX’s vision, blending community development with cutting-edge aerospace innovation.

After overcoming fire safety hurdles, the Boring Company is accelerating its Vegas Loop expansion. The project’s progress signals a transformative boost for Sin City’s transportation and tourism.

Elon Musk’s tunneling company, along with The Las Vegas Convention and Visitors Authority (LVCVA) and Clark County, resolved fire safety concerns that delayed new stations.

“It’s new. It’s taken a little time to figure out what the standard should be,” said Steve Hill, LVCVA President and CEO, during last week’s board meeting. “We’ve gotten there. We’re excited about that. We’re ready to expand further, faster, than we have.”

Last month, the company submitted permits for tunnel extensions connecting Encore to a parcel of land owned by Wynn and Caesars Palace. The three tunnels are valued at $600,000 based on country records.

Plans for a Tropicana Loop are also advancing, linking UNLV to MGM Grand, T-Mobile Arena, Allegiant Stadium, Mandalay Bay, and the upcoming Athletics’ ballpark. Downtown extensions from the convention center to the Strat, Fremont Street Experience, and Circa’s Garage Mahal are also in the permitting process.

“Those are all in process,” Hill noted. “We’ve got machines that are available to be put in the ground. I think we’ve reached a framework for how these projects are going to work and how they’ll be permitted from a safety standpoint, as well as a building standpoint.”

The Boring Company has six boring machines, with three currently active in Las Vegas. Last week, TBC announced that it successfully mined continuously in a Zero-People-in-Tunnel (ZPIT) configuration, enabling it to build more tunnels faster, safer, and at a more affordable rate.

Tunneling under Paradise Road is underway as The Boring Company works on the University Center Loop. The University Center Loop is expected to connect to the Las Vegas Convention Center within two months, linking to the Westgate tunnel. The full Vegas Loop will span 104 stations and 68 miles. Even though The Boring Company’s tunnel network in Las Vegas isn’t nearly finished, it has already become a key attraction in the city.

“It’s such a great attraction for shows that are looking at this building (convention center) and we’re going to be connected to everybody in town,” Hill said. “It’s a real difference-maker.”

A few Vegas Loop stations are already operational, including those connected to Resorts World, Westgate, Encore, and all the Las Vegas Convention Center Loop stations. The Downtown Loop, which connects to the downtown area, and the Riviera Station, the hub that leads to Resorts World with Westgate destinations, are also operational.
