Tesla Model S is approaching a 400-mile range, says Elon Musk
CEO Elon Musk said during the Tesla Q4 2019 earnings call that the Model S is getting closer to achieving a 400-mile range as battery technology improves and as important pieces of the puzzle come into play to achieve the ambitious.
One investor asked the Tesla chief when the Models S and Model X will shift from 18650 cells to 2170 cells since this could be the reason why the sales of the pricier electric vehicles in the Tesla garage have stayed flat. Elon Musk explained Tesla’s current rationale for the Model S as follows.
“The core chemistry inside the 18650 cells has improved many times over the years so it’s really the form factor as opposed to a core technology…We’re pretty happy with the energy content, the improvements, and the efficiency of the vehicle. We’re rapidly approaching a 400-mile range for the Model S, for example,” Musk said.
The Model S has an EPA-certified range between 348 miles and 373 miles while the Model X SUV can go between 305 miles and 328 miles on a single charge. Meanwhile, the entry-level Standard Range Plus Model 3 can travel 250 miles on a charge, while the Performance and Long Range AWD variant can go 322 miles. Musk noted that the figures in the Model S and X order pages are actually conservative.
“Actually, the Model S and X actually have more range than we are currently stating on the website. We just haven’t gotten around to updating the EPA-certified number but the actual range of the Model S and X are above what the website says they are,” Musk said.
While Musk did not provide a direct answer when the Model S and X will switch from 18650 to 2170 battery cells or will there really be a need to do that, the Tesla co-founder and chief executive confirmed last November that the company is planning to use a new battery pack for the Plaid Model S and Model X, which features a three electric motor setup.
New hardware incoming.
Integrated inductive phone charger (Qi) for S/X cars.
Two new S/X battery types in several configs (not yet sure of the capacity – TBD)
new lumbar (so new seats?)
New charge port type.
New suspension version.
I would speculate all these are imminent 1/— green (@greentheonly) January 25, 2020

Recently, Tesla community hacker Green spotted two new battery types with several configurations for the Models S and Model X. This could be related to the release of the Plaid variants, as well as upcoming announcements during the Tesla Battery Day that’s tentatively scheduled to happen in April.
During the Q4 2019 earnings call, Musk was also asked what it plans to do with Maxwell Technologies. Tesla completed the acquisition of the company that is focused on batteries and ultracapacitors in May 2019.
The Tesla chief was quick to reply that “It’s an important piece of the puzzle.”
“We’re going to talk about this in battery day which is probably April and then a lot of these questions will be answered. I think it’s going to be a very compelling story,” he said. “I think it’s gonna actually blow people’s minds. It blows my mind,” Musk added.
Tesla Energy has introduced the Powerwall Lease in conjunction with Tesla Electric, making the service available in Texas. This new option delivers whole-home backup power using two Powerwall units for a net monthly cost of $35 after credits, accompanied by a low fixed electricity rate.
Under the lease terms, customers pay a one-time order fee of $100. The base lease payment for the two Powerwalls is approximately $122 per month during the first year, subject to a 3 percent annual escalator thereafter. Enrollment in a qualifying Tesla Electric Backup plan or Virtual Power Plant plan provides an $87 monthly credit.

This credit lowers the effective cost to roughly $35 per month plus applicable tax.

Installation of the standard system carries no additional charge. The package features Storm Watch for outage protection and allows complete management through a single Tesla application. The system supplies continuous whole-home backup capability.
The Powerwall system enables households to maintain electricity during severe storms that disrupt the utility grid. When outages occur, the batteries automatically provide seamless backup power to the home.

Tesla Storm Watch monitors weather forecasts and ensures the units are fully charged ahead of anticipated severe weather events so that power remains available throughout the disruption, keeping lights, refrigeration, and other essential systems operating without interruption.
Availability is restricted to select Texas locations where retail electric choice exists. Participants must lease exactly two Powerwall units and maintain continuous enrollment with Tesla Electric. Solar panels cannot be included under this particular lease arrangement.
The monthly credit activates automatically once the system is installed, receives permission to operate, and enrollment is confirmed. To retain the credit, customers are required to stay enrolled in Tesla Electric and fulfill all program conditions.
Nonstandard installations that involve electrical upgrades or special permitting may lead to extra expenses and might impact eligibility for the credit, so be sure to check with either your installer or Tesla to ensure you will still qualify.

Elon Musk continues to tease the unveiling event for the Tesla Roadster, a continuing trend that has grown into a bigger game of “When” for fans who have been waiting years for the car to finally enter production.
A video shared on X of the Joe Rogan Experience podcast that Musk appeared on last year, teasing the Roadster unveiling, was shared once again on the social media platform. The poster said the Roadster event will be “unforgettable.”
Musk agreed:
Yes

The timing is interesting because just yesterday, Musk said that we will be getting flying cars, and for years, Tesla has hinted that it could develop a SpaceX cold gas thruster package that would help the car float or fly for a short period of time.
It would be reasonable to assume Tesla’s major delays with this unveiling event are likely caused by the company’s need to break the rules and push the envelope on nearly everything. Last July, Lars Moravy, Tesla’s VP of Vehicle Engineering, said:
-
“Roadster is definitely in development. We did talk about it last Sunday night. We are gearing up for a super cool demo. It’s going to be mind blowing. We showed Elon some cool demos last week of the tech we’ve been working on and he got a little excited.”
The latest updates that Tesla has given us are that the Roadster is in design development, and it did have several potential dates for an unveiling event this year, including April. It was then pushed to August.
However, there are no clues as to when Tesla will be ready, and fans are certainly getting frustrated with the delays.
For what it is worth, Franz von Holzhausen told Jay Leno this week that the event would be “very soon.”
We sure hope.

Tesla’s driverless Cybercab just passed a big test with State Governor
Florida’s governor rode Tesla’s Cybercab at a closed test track and called the experience impressive.
Florida Governor Ron DeSantis rode in a Tesla Cybercab on a closed test track this week and came away impressed, posting on X that the vehicle “successfully navigated all hazards — a kid running into the street, a crash with police stopping traffic, a Model S cutting us off, etc.” He called the ride “impressive.”
The stop was part of a broader event Monday at SunTrax, a 775 acre state owned proving ground in Auburndale that Florida built specifically to test autonomous and connected vehicles before they reach public roads. Standing next to a gold Cybercab, DeSantis described the car in plain terms: “You go in there and you just sit. You have a screen. There’s no steering wheel, no pedals. Clearly these things could be very beneficial.”

DeSantis paired the praise with a caveat that has followed autonomous vehicles since the category existed. “You don’t want to be in an autonomous vehicle and it drives you into a ditch. That would not be good,” he said, framing safety validation as the gate before wider deployment.
SunTrax, the 2.25 mile oval which the state calls the only high speed autonomous vehicle test track in the Southeast, can simulate rain, pedestrian crossings, hills and crowded urban conditions at highway speeds, letting companies push a car past what an early public rollout would risk. Tesla, Waymo and Beep all use the facility, and Florida’s regulatory approach, among the most permissive for autonomous vehicles in the country, doesn’t require a human operator inside a fully autonomous car.

Tesla has reason to want the blessing of Florida and states beyond, as the Cybercab entered volume production at Gigafactory Texas this spring and has since self certified as SAE Level 4 under Texas law. Public road testing so far has kept a safety monitor in the passenger seat, and Florida is where Tesla has been expanding its existing Model Y based Robotaxi service instead, adding Miami in July and then Orlando and Tampa two weeks later. A closed track endorsement from a sitting governor doesn’t change any of that, but it does put Tesla’s newest hardware in front of a state that has already shown it will move fast on rules.
