Tesla to allow MCU upgrade for older Model S and X for better gaming experience
Elon Musk dropped several updates on Twitter over the weekend, covering several aspects of Tesla’s vehicles. Among these are the release date for firmware Version 10, the unveiling of the Tesla Pickup Truck, some games that are coming to the Tesla Arcade, and even a Media Control Unit (MCU) retrofit that will be made possible for older Model S and Model X vehicles.
Musk’s comments come amidst interactions on Twitter about the Tesla Arcade’s new titles, which include exciting games such as Cuphead and Fallout Shelter. While responding to a Tesla owner who stated that he would be happy to pay for an MCU and LTE upgrade for his vehicle, Musk responded that it would indeed be possible to retrofit older Model S and X units with company’s newer MCUs.
Providing MCU upgrade options for older Model S and Model X will further emphasize the idea that Teslas are vehicles that only improve over time. It would, for one, allow even the company’s older vehicles to gain access to some of the newest features found in cars produced today, including the growing library of titles in the Tesla Arcade.
MCUs in Model S and Model X vehicles produced prior to March 2018 are equipped with 2011-era NVIDIA Tegra-3 chips, which worked well for the vehicles’ basic features but lacked in smoothness and speed compared to the Model 3’s Intel-powered MCU. Tesla introduced a newer, faster MCU for the Model S and Model X in March 2018, partly as a way to ensure that the media units of its vehicle lineup share the same speed and performance.
While confirming the rollout of the newer hardware, Tesla noted then that the newer media units were part of the company’s consistent drive to steadily improve its vehicles. In a statement to Teslarati, the electric car maker also explained that the new MCUs would not dramatically affect the user experience of its vehicles.
Tesla was able to buffer the performance discrepancy between its older and newer MCUs by rolling out a software update that optimized the performance of pre-March 2018 media units. Inasmuch as this made the user interface of MCU1 vehicles almost as smooth as the newer, Intel-powered units, later features such as the Tesla Arcade were eventually made exclusive to cars equipped with post-March 2018 MCUs.
It should be noted that Elon Musk has mentioned an MCU retrofit option for older Model S and Model X vehicles in the past. “Yes, you can upgrade hardware, although we also wrote software to accelerate rendering on old MCU. Coming out soon & makes a big diff,” Musk tweeted as a response to a Tesla owner who asked if he could retrofit his vehicle with the newer media unit. With his recent comments, perhaps an MCU retrofit for older vehicles would indeed be in order.

Tesla’s reason for Starlink integration on Cybercab might surprise you, as the company’s Head of AI, Ashok Elluswamy, finally shed some light on the reason they are putting a satellite internet terminal on its ride-hailing-geared vehicle.
On Monday, Tesla officially confirmed that it would integrate Starlink V5 terminals into Cybercab vehicles, something many Tesla fans had figured the company would do, as the vehicle is primarily geared toward giving rides without any passenger intervention.

The ability to access the internet would allow riders to work or play in the car with their devices. It seemed like a more-than-reasonable feature to add to the Cybercab, which made its way off the production lines for the first time earlier this year.

However, the move is not for the rider, as Elluswamy confirmed on Monday night. Instead, it’s actually for Tesla to be able to have a constant connection to the cars in the Robotaxi fleet so it can troubleshoot issues, contact riders, or resolve other issues.
Elluswamy said:
“It is still not required for safe operation of the vehicle. Connectivity is primarily meant for navigation, customer service and, in general, fleet management.”

Many initially assumed the option of constant connectivity would be enabled on the Cybercab for passenger entertainment or work. With the Cybercab, passengers won’t be doing anything but enjoying the ride, so it seemed more than logical that they would be hanging out with Starlink internet access as an amenity.
However, Tesla’s primary concern with Robotaxi is safety, and nailing these first unsupervised rides is a crucial step to setting a good narrative on how effective driverless transportation can be.
Being able to get in touch with passengers or a vehicle if something is wrong is a crucial part of the overall experience, and preventative measures are being taken by Tesla to ensure a smooth process, even in the worst-case.
Tesla has expanded its Robotaxi program in Florida to include two new cities: Tampa and Orlando.
This marks the second and third cities to be added to the company’s available locations for autonomous ride-hailing in the Sunshine State, joining Miami, which was the first Florida city to offer Robotaxi rides.
Tesla announced the addition of Orlando and Tampa to the Robotaxi program on Tuesday morning. The cities now join Austin, Dallas, Houston, Miami, and the San Francisco Bay Area as locations where Tesla can operate its Robotaxi platform:

These rides are unsupervised, as AI Head Ashok Elluswamy confirmed the suite in Florida is operating without safety drivers or anyone within the cabin to assist with operation.
Orlando Tesla Robotaxi Operation
The geofence in Orlando covers a prominent irregular shaded zone on the map, roughly 4-6 miles across in key dimensions, so it likely measures somewhere between 25 and 45 square miles, which is comparable to other early Tesla launches in other cities.
It encompasses central and southern areas bounded by major highways including SR-417 and SR-528, including parts of the Orlando metro core, tourism-adjacent zones, and residential/commercial districts. This represents an initial targeted rollout in a tourist-heavy region, positioned for quick expansion via Tesla’s software updates.
Tampa Tesla Robotaxi Operation
In Tampa, the shape of the geofence is a shaded polygon covering key neighborhoods, explicitly including West Tampa, Tampa Heights, Hyde Park, and downtown Tampa proper, with boundaries along major roads and the Hillsborough River area.
This focuses on high-demand central zones and will offer tourists and citygoers rides without drivers.
Robotaxi Progress
Tesla has been operating Robotaxi since last June, when it launched in Austin. The geofences in most regions have already expanded several times since their launch last year, but the bigger complaint is vehicle availability. Tesla has been working to add more Robotaxi-enabled vehicles to its fleet.
The company still plans to utilize its Cybercab, a new vehicle that is being produced at Gigafactory Texas, for the Robotaxi suite alongside the Model Y, which has been the vehicle of choice for Tesla with early operations.
