Kman has been producing videos about Tesla since 2013, when he took delivery of a 60 kWh Model S. His latest opus is a four-part collection of handy tips and tricks for Tesla drivers.
Kman includes a raft of recommendations for increasing range. Most of these will be familiar to any energy-conscious driver, but the analytically-minded Kman has tested the techniques, and offers a pretty precise assessment of exactly how much juice each suggestion will save.
Obviously, it’s good to keep the total vehicle weight down – consider taking that bowling ball out of the trunk if you don’t use it much. However, Kman has found that the additional weight of passengers and cargo affects range far less than other things, such as tire pressure.
Like most cars, Model S has a sticker on the door jamb listing the recommended tire pressure. However, Kman has found that using the recommended pressure increases his energy consumption (and feels “squishy”), so he uses 50 psi on the rear and 48 on the front, instead of Tesla’s recommended 45.
We all know that Tesla’s Range Mode increases range. Kman explains exactly how it works, and what the trade-offs are (mostly stuff you can do without).
Slow down! Everyone knows that vehicles (electric or fossil) are more efficient at slower speeds. Kman has calculated that the optimum speed for Model S is 24 mph. If you could somehow manage to drive around at a constant 24 mph, you should get as much as 550 miles of range.
Auto racing fans know that drafting – the practice of following closely behind another vehicle to cut down wind resistance – saves energy. Tesla’s adaptive cruise control makes this easy – just set the desired distance from the vehicle ahead of you. Kman claims he has seen a 40% increase in range drafting a semi truck.
Climate control is another well-known energy hog, but in an EV, heating uses much more power than cooling (gas cars use waste heat from the engine for cabin heating). If you can get by with the Tesla’s seat heaters, you’ll save some range, as using them is much more efficient than heating the whole cabin.

There seems to be a bit of controversy when it comes to ride height. Theoretically the lowest suspension setting saves range on the highway, but some Tesla drivers claim that it increases tire wear, and that medium ride height is best. Your mileage may vary.
Model X is rated to tow a trailer of up to 5,000 pounds, but it will cost you in terms of range. Figure on at least a 50% reduction in range when towing. Kman points out that the aerodynamics of a trailer are much more important than weight. Officially, Model S can’t tow at all, but Kman claims it can tow up to 2,000 pounds (sounds like something that could void the warranty if anything goes wrong – be careful).
Next, Kman debunks the common belief that charging to 100% reduces battery life. In fact, the big no-no is charging to 100% and then leaving the car sitting around in high temperatures. But topping up is fine if you’re going to be driving right away, and it’s the easiest and most obvious way to maximize your range.
No matter how careful you are, you’re going to run out of energy eventually, so it’s best to be prepared for various charging scenarios, especially when taking road trips. It’s handy to have a collection of charging adapters in the car, including a CHAdeMO adapter and a couple of adapters for different types of 240-volt receptacles (even if you have to spend some time searching for them, as Kman does). And keep a heavy-duty extension cord in the car in case you ever need to plug into a regular outlet somewhere on the road.
Another handy accessory is a ChargePoint account, which gives access to thousands of public chargers. Theoretically you can initiate charging just with the smartphone app, but that won’t work if there’s a dodgy internet connection, so order the free card and keep it in your vehicle (there are various other regional charging networks, some of which require their own cards).

Elon Musk drops a surprise update on Boring Company’s next big dig
Musk says Boring Company could shrink the Austin to San Antonio drive to just minutes.
Elon Musk says The Boring Company is working on what he called “a simple, precursor Hyperloop” tunnel connecting Austin and San Antonio, targeting speeds above 200 mph and cutting a drive that can take up to two and a half hours down to a consistent under 30 minutes. Musk posted the idea on X Sunday, in a reply to a repost of an AI generated video imagining a science fiction future with human colonies on other worlds, which he shared with the line “This is the future we shall bring into being.”

The Boring Company’s own account picked up the idea in the same thread, adding a detail about how the trip would actually work: “Because Loop/Hyperloop is express (i.e. no intermediate stops), one could travel from an Austin parking lot to a favorite San Antonio restaurant in about 30 minutes. As long as they both have Loop stations.” That framing ties the proposed intercity link to the same station model the company already runs in Las Vegas, where riders enter the tunnel network through small, garage style stops rather than one central terminal.
This is not the company’s first run at the Austin to San Antonio corridor. Boring Company floated tunnels between the two cities as far back as 2021, and later competed for a separate San Antonio Loop project tied to the airport before that specific bid stalled. Pitches for tunnels in Chicago, Los Angeles, and a New York to Washington corridor have followed a similar pattern of big announcement without a shovel in the ground.
What is different this time is the balance sheet, especially since The Boring Company closed a 3 billion dollar funding round led by investors in the United Arab Emirates earlier this month at a valuation near 23 billion dollars, giving the tunneling company more capital to chase speculative projects than it had during its earlier Texas pitches. The company is also mid-build on two other intercity systems it has actually broken ground on, inc;luding a Nashville tunnel linking downtown to the airport, where a second boring machine finished commissioning in June, and its Las Vegas network, where the station count keeps climbing on paper faster than tunnels get dug.
That gap between announcement and execution is the reason to treat Sunday’s post as an opening bid rather than a project. A tunnel spanning roughly 80 miles between two metro areas, running at speeds Boring Company has not demonstrated over any real distance, would dwarf anything the company has built. For now, the Austin to San Antonio Hyperloop exists as a caption under an AI generated space video.

Tesla eyes supply partners for Optimus mass production
Tesla certified three Chinese suppliers for Optimus mass production, signaling its robot timeline is accelerating.
Tesla’s robotics team traveled to Ningbo, in China’s Zhejiang province, on September 16 and spent the following day auditing component suppliers for Optimus, according to a Bloomberg report cited by RobotAIGeek. The visit moved three manufacturers from provisional status to certified mass production partners: Tuopu Group, which handles actuators and chassis components, Ningbo Joyson Electronic, a sensor supplier, and Zhejiang Sanhua Intelligent Controls, which builds thermal management systems. All three already supply parts to Tesla’s electric vehicles, and the audit reportedly came with fresh orders that supply chain reports put at an initial batch of roughly 5,000 units.
Tuopu, Joyson, and Sanhua built their manufacturing base serving the automotive industry, where tolerances and volume requirements are already close to what a mass produced humanoid robot demands. Sanhua in particular has history here. Teslarati reported last October that the company had received a roughly $685 million order for linear actuators tied to Optimus, a volume industry watchers estimated could cover around 180,000 robots once production ramped.
Supply chain reports tied to this week’s audit put Tesla’s near term production goal at about 1,000 Optimus units a week by late September, rising to 2,000 to 2,500 units a week by the end of the year. That pace would put real weight behind the timeline Tesla has been building toward since May, when it wound down Model S and Model X production at Fremont to convert that floor space into a dedicated Optimus line targeting one million units annually. JPMorgan analysts who toured the factory in August confirmed the conversion took roughly four months, a pace Musk has called unprecedented for a facility that size.
New drone video shows Tesla’s Optimus Factory reaching a turning point
Fremont is only the first phase. A second, larger Optimus plant is rising at Gigafactory Texas, where drone footage shared by Joe Tegtmeyer last week showed the structural steel nearing completion on the north end of the building. Tesla has said that facility is meant to eventually support production of up to 10 million units a year, though volume output there is not expected before 2027.
Commercial sales of Optimus are still targeted for the second half of 2027, but production is expected to start well before then. JPMorgan analyst Rajat Gupta has said Tesla’s “Optimus Academy” program, which uses early units to collect real world training data inside Tesla’s own facilities, is expected to be running later this year. Bloomberg Intelligence analyst Ian Ma described the Ningbo audits as “a positive commercialization signal for China’s humanoid supply chain,” noting that sentiment could improve further if the visit leads to confirmed supplier nominations and larger orders. The Solactive China Humanoid Robotics Index rose about 1.4% on the news, though it remains down roughly 30% for the year.

Tesla primes Cybercabs for 4K streaming and high bandwidth gaming with Starlink integration
Tesla is now shipping Cybercabs from Giga Texas with Starlink hardware built in as standard.
Tesla’s Cybercabs are now leaving Gigafactory Texas with Starlink hardware on the rear hatch in significant numbers, according to drone footage captured Tuesday by longtime Austin drone observer Joe Tegtmeyer. Production at the factory ramped back up after the Labor Day weekend, and his flyover of the outbound lot showed rows of gold Cybercabs alongside Model Y Long Wheelbase units, many carrying the satellite module for the first time as standard equipment rather than a one off retrofit.
Giga Texas today is busy with production coming back up following the long weekend. Of interest today in the outbound lot is the appearance of hundreds of Mode; YL’s and many more Cybercabs and for the 1st time equipped with the Starlink module one the hatch in big numbers.

Tesla first showed Starlink built into an actual Cybercab on August 10, when the Robotaxi account posted images of a single gold unit with the antenna integrated into the roofline above the taillights and called it the first Cybercab with Starlink integration. That followed a July reveal where Tesla and Starlink jointly posted a cutaway diagram of the antenna placement without a working vehicle to back it up. Ashok Elluswamy, Tesla’s VP of AI software, said at the time that the connection isn’t required for the car to drive itself. It exists mainly for navigation, customer service and keeping tabs on the fleet.
Musk has made a different case in public. During Tesla’s Q2 earnings call, he said the company can’t afford robotaxis stranded in what he called “Bermuda Triangles of lack of cellular connectivity,” and he separately claimed on X that Starlink will eventually reach every Tesla built, calling it the only way to deliver high bandwidth to billions of vehicles. He has also pitched the antenna as an entertainment upgrade, telling riders they would be able to stream 4K video or play games during a trip.
The rollout has moved fast since. Robotaxi service opened to the public in Austin on September 3, and Cybercabs had already been spotted with Starlink hardware in Houston and near Miami International Airport in the weeks before Tuesday’s factory footage showed the module shipping at volume rather than on scattered test units. Whether the satellite link earns its keep is still an open question. Tesla’s unsupervised service currently runs in dense metro geofences in Texas and Florida, markets where cellular coverage is already strong, which is not where the rural dead zones Musk describes tend to show up.
