The first Tesla Semis have been delivered, and so has the promise to adhere to the company’s mission: accelerate the advent of sustainable transportation. Yes, it took five years from the first peek at the Semi and three years longer than initially projected, but the Semi is set to change the trucking industry the same way the Model S, 3, X and Y changed the automotive industry.

While Tesla has been increasing the number of passenger vehicles it produces worldwide; these large trucks are not needed at the same level. The company states that 15 million passenger vehicles are sold in the U.S. every year, but only a couple hundred thousand big rigs. So why would Tesla put so much time and effort into something that doesn’t sell as many units?

Musk’s response, “it seems like a small percentage, but it (semi-trucks) is actually 20 percent of U.S. vehicle emissions. Because you’ve got a huge vehicle, and it’s being driven all the time.” Musk said, “Over a third of all the articulate emissions (are from semi-trucks). So, from a health standpoint, particularly in cities, this is a huge impact, like gigantic — that’s why we are doing it.”

The Semi is a Recruiting Tool for Truckers

Back in 2017, Elon Musk said he could drive a Tesla Semi. That was quite a statement, given that trucks this size usually come with anywhere from 10 to 18 gears. However, the CEO did just that five years later. He drove the newest member of the Tesla lineup to the event to deliver the Semi to Pepsi Co. Musk said, “It’s like driving a Tesla, literally.” That is because it’s built the same way with a single stalk to put the vehicle in drive, reverse, neutral or park. “It looks sick. I mean, you want to drive that! That thing looks like it came from the future… It’s fun. It looks awesome, there is a big shortage of drivers, so if you are a truck driver and want the most bad ass rig on the road - this is it.”

The Semi is known as the Beast

Senior Manager of Tesla’s Semi Engineering, Dan Priestley, explained why many people refer to the Semi as the beast. “(It has) three times the power than any diesel truck on the road right now. So you’ve got all the power you need to get the job done, but the other reason that it’s a beast is because it is efficient, you can go 500 miles on a single charge on one of these things. It’s the mix of those two - this is a game-changer. What’s awesome is both of those are enabled by our 1000-volt powertrain. This is the first vehicle we are doing with that.”

That max power combined with hyper-efficiency is due to a tri-motor power train system. One motor is for highway driving and will always be engaged, while the other two are for torque and acceleration. Those motors use the system straight out of the Model S Plaid powertrain. Priestly said, “These are clutched automatically. No driver input is needed. It is seamless.”

Musk commented on the Semi’s performance, “It looks crazy. It looks like an elephant moving like a cheetah.” He was also astonished at the size of the motor powering the Semi. It’s described as the size of a football, “I find it amazing that this enormous thing can be pulled by something that you can carry in your hands — it’s like, wow, that is power density.”

500-mile Range

The Semi has been tested in all conditions in the real world, in a lab and virtually. One of those real-world tests was proving the naysayers wrong by taking the Semi for a 500-mile drive, fully loaded, from Fremont to San Diego on just a single charge.

Elon Musk later revealed on Twitter that the Tesla Semi's current efficiency is about 1.7kWh/mile, but that there is a path for Tesla to make it even more efficient. It's not clear whether the additional efficiency could be achieved through software or if it would require hardware changes. The quoted 1.7kWh/mile efficiency is a pleasant surprise, as many were expecting the truck to have an efficiency of about 2kWh per mile.

V4 Superchargers

Speaking of charging, the new V4 Superchargers were also revealed. They produce 1 megawatt of energy and will be used for the Semi and the Cybertruck.

Tesla's Semi Delivery Event

Musk finished the event with this message: This is going to revolutionize the road, make the world a better place in a meaningful way.

Tesla Is Now Offering Cybertruck Test Drives [List of Locations]

Tesla has begun to reach out to customers in the United States and is offering demo drives of the Cybertruck on an invite-only basis. @brandonhd on X shared the first invite image, and it looks like it's going out quite quickly to multiple locations that have Cybertrucks on display.

Up until now, display vehicles have been for just that – looking, but no touching. Some Tesla delivery centers and showrooms have also allowed viewers to take a seat inside and open it up, but most are still locked away behind the velvet rope.

It’s exciting to see that Tesla has begun to demo them – and it can only be so long until demo drives open up to everyone.

Advisor-led Demo

This Demo Drive is led by a Tesla Advisor – while you’re driving, the advisor will be in the passenger seat, walking you through the experience. They’ll explain steer-by-wire, off-road controls, and will introduce new-to-Tesla buyers to all the features that are currently available.

Once FSD V12.5 comes to the Cybertruck, we’re sure they’ll be demoing its capabilities FSD capabilities as well.

Locations

The list of locations so far for demo drives appears to be fairly limited, but we will hopefully see demo drives roll out throughout the United States, and eventually Canada too. Here is the current list of city/state locations that have seen demo drive invites.

  • Manhasset, New York

  • West Covina, California

  • Los Angeles, California

  • Houston, Texas

  • Orlando, Florida

  • Westmont, Illinois

  • Tucson, Arizona

  • Phoenix, Arizona

  • Delaware

Musk Confirms 'Actually Smart Summon' is Coming in a Revision of FSD V12.5

By Karan Singh
Not a Tesla App

Actually Smart Summon, the successor to Tesla’s Smart Summon feature, has been confirmed to be coming as soon as next month as per Elon Musk. Colloquially known as “ASS”, Actually Smart Summon is supposed to improve on the regular Smart Summon capabilities, which have historically used ultrasonic sensors (USS) to navigate parking lots.

We’re looking forward to Actually Smart Summon, and we’re quite excited about what other features will be unlocked once it finally shows up at our doorstep.

Vision-based Improvements

ASS is supposed to bring Smart Summon to vehicles that don’t have USS – using Tesla Vision. Most recently, Tesla has brought Autopark to vehicles without USS, and Vision-based Autopark has been a huge success. It is faster, more reliable, and smoother than the older USS-based solution. It can also park and maneuver in tighter locations.

Just recently, Tesla returned the Model X’s self-presenting doors, using Tesla Vision. Vision has seen some fantastic improvements, and many people are waiting for ASS to bring forth these improvements to Smart Summon.

Smart Summon Today

Today, Smart Summon is sometimes useful at best, usually a party trick, or downright dangerous at worst. It’s excellent and best used in straight lines, where you have a clear line of sight of the vehicle, and can stop it if doesn’t see an obstacle.

I used Smart Summon today, just before writing this article – my 2022 Model Y (with USS) – did manage to show up just fine – in a straight-line location from where I was parked, after exiting the parking spot fairly cleanly. However, I’ve previously used Smart Summon and have had the vehicle turn towards obstacles, such as cart returns or curbs. Overall, it’s a sometimes-useful feature that has a lot of drawbacks right now.

Smart Summon is also restricted to a certain distance – and it's pretty small. The max distance is shorter than most parking lots, being only about 215 ft (65m). If you’re lucky enough to park close, it's very useful to bring your car right to you.

Actually Smart Summon

ASS will bring FSD V12-like capabilities to Smart Summon – the vehicle will primarily use Vision to drive toward you (or the location you’ve indicated). ASS has been supposed to be coming since about September 2022 and has seen many delays – we’re almost at the 2-year point today.

We’re looking forward to Actually Smart Summon being able to bring the vehicle – safely – right to you. ASS is also one of the key steps towards bringing some other cool features that Elon Musk has previously mentioned – Park Seek and Banish Autopark.

We’re also hopeful that Actually Smart Summon will increase the maximum range a vehicle can be summoned, because the current range is fairly small. Alongside Park Seek and Banish Autopark, we’re closing in on a Robotaxi-based future.

Park Seek and Banish Autopark

When the FSD v12.4 showed up, Elon also mentioned that going forward, vehicles would automatically park themselves when arriving in a parking lot – Park Seek – and that if you got out of the car at the entrance to a business, you could get it to automatically park itself in the parking lot – Banish Autopark. These are two features that are needed for Robotaxi to work – which itself is delayed to October 10th of this year. We’re looking quite forward to them – as in combination with Actually Smart Summon, Tesla has reached the cusp of vehicle autonomy.

A vehicle that arrives, driverless, at the location you’re at, then drives somewhere, parks itself there, and waits for you – is the definition of a Robotaxi.

While we’re likely to have to wait for Banish Autopark and Park Seek just a bit longer, Actually Smart Summon being around the corner is exciting! Gone will be the days of having to run out to your car when you forgot your umbrella – your car will just come right to you instead.
