The new Tesla Roadster is the very definition of a halo car. Embodying all the innovations that Tesla has developed and mastered over the years, the next-gen Roadster is intended, as Elon Musk put it, to give a “hardcore smackdown” to gasoline cars. During the CEO’s appearance at the Ride the Lightning podcast, Musk even candidly mentioned that the upcoming vehicle will have capabilities that are practically “unfair” to its internal combustion-powered competition. 

It has been almost two years since the vehicle was unveiled, and over this time, Tesla has made headway in its electric vehicle tech. Earlier this year, Tesla completed the acquisition of Maxwell Technologies, a company that specializes in supercapacitors and the development of dry battery electrode technology. These innovations, which Tesla has complete access to, are a perfect fit for the next-generation Roadster. 

Munro and Associates Sr. Associate Mark Ellis recently noted during an interview with Tesla owner-enthusiast Sean Mitchell that Maxwell’s tech have immense potential in the electric vehicle segment. “The dry battery technology is game-changing if it comes to pass and they can put it in a car,” he said. Ellis also explained that supercapacitor technology could greatly help electric vehicles in terms of their battery management. 

“One of the issues with the battery is, when I step on the throttle hard, I’m pulling a lot of energy from the battery. And then, when I brake hard, I’m pulling a lot of energy out of the regen, but the batteries can’t take it fast enough. The batteries get really stressed when you try to pull it up too much, so if I had supercapacitors that I could use as a cushion; so when I need energy quickly, (I can) pull it from the supercapacitors and then fill the supercapacitors back up with the battery slowly; and then when I brake, I can capture more of that regen energy and do the supercapacitors faster. I think that just makes logical sense, because now all of a sudden I’ve got a sponge in front of my main energy source and I’m not stressing (the battery) so much,” he said. 

This “sponge” that Ellis mentioned will be greatly beneficial for vehicles like the next-generation Roadster, which is designed to accelerate at incredibly rapid speeds. The Roadster will be insanely quick on a straight line with its 0-60 mph time of 1.9 seconds, and based on Musk’s previous statements about the vehicle, the all-electric supercar will be able to take on track driving as well. This means that the next-generation Roadster will be a monster of a supercar, and it will require serious refinement in terms of its battery and electric motors to maintain its optimum performance.

Tesla is a far more experienced carmaker today than it was when Elon Musk unveiled the next-generation Roadster in 2017. Considering that Tesla is a company with a culture of innovation, it is almost certain that the new Roadster, once it is released, will be a far more refined vehicle than the already-game-changing supercar that shocked the auto industry nearly two years ago. Elon Musk, if any, has mentioned some of these updates, one of which is a SpaceX package that will utilize cold gas thrusters (the same technology used in SpaceX’s Falcon 9 rockets) to help the vehicle’s acceleration, braking, and maneuverability. 

The impending arrival of the next-generation Roadster appears to have started a disruption in the hypercar market. Since the vehicle’s unveiling, other carmakers have introduced all-electric monsters of their own. Among these is the ~$2.5 million, 1,900 hp Pininfarina Battista, the ~$2 million, 1,973 hp Lotus Evija, and the $2.1 million, 1,914 hp Rimac C_Two. Considering that the Roadster will start at around $200,000, the vehicle will likely be closer in price to upcoming premium sports EVs like the Taycan Turbo S, which is expected to command a notably higher price compared to the ~$130,000 Taycan Turbo.

Tesla to lose 64 Superchargers on New Jersey Turnpike in controversial decision

Tesla is set to lose 64 Superchargers on the extremely busy and congested New Jersey Turnpike.

Tesla is going to lose 64 Superchargers on the New Jersey Turnpike after a decision by the Turnpike’s governing body was made not to renew its contract with the automaker.

On Friday, Tesla revealed that the New Jersey Turnpike Authority (NJTA) had officially decided to choose a sole third-party provider for its electric vehicle infrastructure. This resulted in the NJTA not renewing its contract to keep Tesla Superchargers on the toll road.

The NJTA also requested, with its decision not to renew with Tesla, that the company decommission all 64 Supercharger stalls, an unprecedented decision that will remove these plugs from the turnpike, making charging more scarce on the busy roadway.

Tesla detailed the situation on Friday:

“The New Jersey Turnpike Authority (“NJTA”) has chosen a sole third-party charging provider to serve the New Jersey Turnpike and is not allowing us to co-locate. As a result, NJTA requested 64 existing Supercharger stalls on the New Jersey Turnpike to not be renewed and be decommissioned.”

Tesla said it has been preparing for the potential that the Turnpike Authority would make this decision for three years by building 116 Superchargers nearby to still supply drivers with reliable charging infrastructure.

The company also noted that its Trip Planner would adjust automatically.

There were also efforts to maintain a relationship that would benefit both the Turnpike and EV drivers who use it.

Tesla said it offered the NJTA various “above-market commercial items,” like an offer to build Superchargers at all New Jersey Service Plazas with equipment upgrades like screens and adapters for those companies who have gained access to its charging piles but need to utilize the NACS and CCS1 plugs.

The decision is one that seemed to baffle the company, especially as infrastructure is one of the biggest concerns among EV skeptics:

“Tesla always advocates for more infrastructure and co-location with additional third-party charging providers. This drives down costs through optionality, and accelerates EV adoption by having sufficient capacity to shoulder peaks. We expect that ~30 times more fast-charging capacity is needed to get to full EV adoption. NJTA’s decision to remove, rather than add, critical charging infrastructure is a setback for New Jersey’s EV adoption goals of 100% Zero-Emission New Car Sales by 2035. It removes Turnpike access to the most reliable (99.9% uptime), least congested (<1% waiters) and cost-effective (~30% lower $/kWh) charging. “

The company said it was more than willing to invest in Turnpike sites if the Authority or New Jersey Governor Phil Murphy wanted to reverse the decision.

SpaceX hit with mishap investigation by FAA for Starship Flight 9

Starship’s ninth test flight has the FAA requiring a mishap investigation from SpaceX.

SpaceX has been hit with yet another mishap investigation by the Federal Aviation Administration (FAA) related to the company’s ninth test flight of Starship earlier this week.

The FAA said the mishap investigation is “focused only on the loss of the Starship vehicle, which did not complete its launch or reentry as planned.” The agency said the loss of the Super Heavy booster is covered by one of the FAA’s approved test induced damage exceptions requested by SpaceX.

All of Starship and Super Heavy booster debris landed within the designated hazard areas, the FAA confirmed.

SpaceX Starship Flight 9 recap: objectives & outcomes

It said it activated a Debris Response Area out of an abundance of caution as the booster “experienced its anomaly over the Gulf of America during its flyback toward Texas. The FAA subsequently determined the debris did not fall outside of the hazard area. During the event there were zero departure delays, one flight was diverted, and one airborne flight was held for 24 minutes. ”

SpaceX has become accustomed to mishap investigations by the FAA, as they have been impacted by them on several occasions in the past, including on Flight 8. However, they are a precautionary measure and usually are resolved within a few weeks.

Flight 9 was one of SpaceX’s most eventful, as there were several discoveries during the launch. First, it was SpaceX’s first time reusing a Super Heavy booster, as the one utilized for Flight 9 was also used on Flight 7 in January.

Contact with the booster and Starship were both lost during Flight 9. SpaceX said the booster was lost “shortly after the start of landing burn when it experienced a rapid unscheduled disassembly approximately 6 minutes after launch.”

Meanwhile, Starship was set to make a splashdown in the Indian Ocean, but the vehicle was lost about 46 minutes into the flight, SpaceX said in a mission recap.

It was an improvement from the previous two flights, as both 7 and 8 resulted in the loss of Starship after just a few minutes. Flight 9 lasted considerably longer. These flights are also not intended to make it to Mars, despite what other reports might try to tell you.

These are ways to gain information for when SpaceX eventually tries to get Starship to Mars.

Tesla bull writes cautious note on Robotaxi launch: ‘Keep expectations well contained’

Morgan Stanley’s Adam Jonas is more cautious about Tesla’s upcoming Robotaxi launch.

Tesla analyst Adam Jonas of Morgan Stanley is telling investors to be wary of the Robotaxi details CEO Elon Musk revealed this week, after a report seemed to land on the prospective launch date of the platform in June.

Earlier this week, a report from Bloomberg indicated Tesla had internally landed on a tentative date of June 12 for its Robotaxi launch in Austin. Shortly after, Musk detailed the successful testing Tesla has already performed without anyone in the driver’s seat.

He also indicated Teslas would self-deliver to customers in June.

Analysts are now sending out investor notes on the announcement Musk made, along with the Bloomberg report. Jonas’s note is more cautious than others.

Jonas believes Tesla needs to shed more details before investors and fans of the company get too excited. He believes there is more information that could be released, but until then, he is suggesting investors “keep expectations well contained.”

He wrote:

“As is typical for highly anticipated Tesla events, we would keep expectations well contained for the (reported) June 12th Cybercab launch event in Austin. However, we would look for a continued stream of updates for the performance and growth of the network thereafter (numbers of cars, miles, trips, etc.) in the days and weeks that follow.”

The tone of Jonas’s note contradicts that of Wedbush’s Dan Ives, who believes the “golden age of autonomous” lies in Tesla’s hands. He seems to believe Tesla will come through on its June 12 launch.

Morgan Stanley’s note is slightly more

Jonas is obviously still bullish, but is much more tentative to move forward with an attitude that communicates skepticism about what Tesla has revealed.

Jonas and Morgan Stanley have a $410 price target on Tesla shares with a ‘Buy’ rating. Tesla stock is trading at around $358 at 12:15 p.m. on the East Coast.
