Tesla designs their electric vehicles from the ground up; BMW – not so much

Published

on

One distinct competitive advantage often considered for Tesla is the company’s complete commitment to an electric vehicle future. Their cars don’t sacrifice anything in the design process — they’re built from the ground up to take advantage of a wholly unique electric vehicle architecture. And, according to Reuters, “Electric motors are smaller than petrol or diesel engines, so electric vehicles designed from scratch can benefit from better interior packaging which allows a bigger passenger space.”

It’s reported that, “There are two ways to make battery-driven vehicles: use a clean-sheet design like Tesla, or a traditional vehicle platform that can use all types of motor: combustion, electric or a hybrid of the two.” In contrast to Tesla, BMW’s vision for the future appears to be one that allows for an amalgam of vehicle technologies crammed into one design as opposed to committing, completely, to an electric vehicle architecture.

BMW is, “betting they can mass produce new electric cars based on conventional vehicles.” Looking at their plans, “BMW is preparing to launch an all-electric version of its popular X3 off-roader by 2020, and… a new electric BMW, the i Vision Concept, [which] will use the same underpinnings as future versions of the BMW 3-Series. Electric and petrol versions will be built on the same production lines.”

According to BMW’s research and development chief Klaus Froehlich, “It is easy to build an electric car. It is difficult to earn money with it.” Reuters notes that clean-sheet design for electric vehicles does, indeed, require significant upfront investment as, “their unique design requires a dedicated production line and expensive new factories.” Therefore, BMW looks to be hedging its bets by relying on the same, antiquated production lines that pump out gas cars. And, they’re looking to pre-existing gas car architectures repurposed (and reborn) as electric cars.

On the one hand, “Froehlich said vehicle designs dedicated to only one powertrain were no longer required.” However, Carsten Breitfeld, a former electric vehicle engineer at BMW, disagrees. Breitfeld, who headed BMW’s i8 sportscar program, explains, “Trying to adapt a volume architecture to produce electric, diesel and plug-in hybrids is fundamentally flawed, because these products will be compromised.” Breitfeld points to Tesla’s clean-sheet design as the right approach: “Tesla was pathbreaking with its electric car, and that’s what everybody is seeking to develop now.”

This difference of opinion became a divisive issue, internally, at BMW. And, “Breitfeld is so convinced of this that he left his job at BMW in 2015, where he was part of a small team working on clean-sheet electric cars.” The team’s only clean-sheet EV design that made it to production was its i3. However, it turns out that BMW’s internal “i Division” team is now moving its focus away from electric cars altogether.

Does compromising EVs with gas car design characteristics epitomize a company clinging to the past? “Breitfeld sees the German carmakers’ answer to the expected surge in electric car demand – putting an electric motor in a conventional car – as a mistake. He believes it leaves the industry vulnerable to a ‘Nokia moment’: when a new player uses a transformational design to seize control of an established market, as Apple’s iPhone stole a march on Finnish mobile phone giant Nokia a decade ago.”

Tesla hints at Starlink integration with recent patent

“By employing polymer blends, some examples enable RF transmission from all the modules to satellites and other communication devices both inside and outside the vehicle.”

Tesla hinted at a potential Starlink internet terminal integration within its vehicles in a recent patent, which describes a vehicle roof assembly with integrated radio frequency (RF) transparency.

The patent, which is Pub. No U.S. 2025/0368267 describes a new vehicle roof that is made of RF-transparent polymer materials, allowing and “facilitating clear communication with external devices and satellites.”

Tesla believes that a new vehicle roof design, comprised of different materials than the standard metallic or glass elements used in cars today, would allow the company to integrate modern vehicular technologies, “particularly those requiring radio frequency transmission and reception.

Instead of glass or metallic materials, Tesla says vehicles may benefit from high-strength polymer blends, such as Polycarbonate, Acrylonitrile Butadiene Styrene, or Acrylonitrile Styrene Acrylate.

These materials still provide ideal strength metrics for crashworthiness, stiffness for noise, vibration, and harshness control, and are compliant with head impact regulations.

They would also enable better performance with modern technologies, like internet terminals, which need an uninterrupted signal to satellites for maximum reception. Tesla writes in the patent:

“By employing polymer blends, some examples enable RF transmission from all the modules to satellites and other communication devices both inside and outside the vehicle.”

One of the challenges Tesla seems to be aware of with this type of roof design is the fact that it will still have to enable safety and keep that at the forefront of the design. As you can see in the illustration above, Tesla plans to use four layers to increase safety and rigidity, while also combating noise and vibration.

It notes in the patent that disclosed examples still meet the safety requirements outlined in the Federal Motor Vehicle Safety Standards (FMVSS).

Starlink integrated directly into Tesla vehicles would be a considerable advantage for owners. It would come with a handful of distinct advantages.

Initially, the inclusion of Starlink would completely eliminate cellular dead zones, something that is an issue, especially in rural areas. Starlink would provide connectivity in these remote regions and would ensure uninterrupted service during road trips and off-grid adventures.

It could also be a critical addition for Robotaxi, as it is crucial to have solid and reliable connectivity for remote monitoring and fleet management.

Starlink’s growing constellation, thanks to SpaceX’s routine and frequent launch schedule, will provide secure, stable, and reliable internet connectivity for Tesla vehicles.

Although many owners have already mounted Starlink Mini dishes under their glass roofs for a similar experience, it may be integrated directly into Teslas in the coming years, either as an upgrade or a standard feature.

Tesla supplements Holiday Update by sneaking in new Full Self-Driving version

It seems Tesla was waiting for the Hardware 4 rollout, as it wanted to also deploy a new Full Self-Driving version to those owners, as it appeared in the release notes for the Holiday Update last night.

Tesla has surprised some owners by sneaking in a new Full Self-Driving version with the wide release of the Holiday Update, which started rolling out to Hardware 4 owners on Friday night.

Tesla has issued a controlled and very slow release pattern with the Holiday Update, which rolls out with Software Version 2025.44.25.5.

For the past two weeks, as it has rolled out to Hardware 3 and older Tesla owners, the company has kept its deployment of the new Software Version relatively controlled.

It seems Tesla was waiting for the Hardware 4 rollout, as it wanted to also deploy a new Full Self-Driving version to those owners, as it appeared in the release notes for the Holiday Update last night.

Tesla Full Self-Driving v14.2.1.25 made its first appearance last night to Hardware 4 owners who are members of the Early Access Program (EAP). It appears to be a slight refinement from FSD v14.2.1, which has been out for a couple of weeks.

Many owners welcome the new FSD version, us included, because we’ve been less than impressed with v14.2.1. We have experienced some minor regressions with v14.2.1, especially with Speed Limit recognition, Speed Profile tinkering, and parking performance.

As it stands, Full Self-Driving is still particularly impressive, but Tesla is evidently having an issue with some of the adjustments, as it is still refining some of the performance aspects of the suite. This is expected and normal with some updates, as not all of them are an improvement in all areas; we routinely see some things backtrack every once in a while.

This new FSD version is likely to take care of those things, but it also includes all of the awesome Holiday Update features, which include:

  • Grok with Navigation Commands (Beta) – Grok will now add and edit destinations.
  • Tesla Photobooth – Take pictures inside your car using the cabin-facing camera
  • Dog Mode Live Activity – Check on your four-legged friend on your phone through periodic snapshots taken of the cabin
  • Dashcam Viewer Update – Includes new metrics, like steering wheel angle, speed, and more
  • Santa Mode – New graphics, trees, and a lock chime
  • Light Show Update – Addition of Jingle Rush light show
  • Custom Wraps and License Plates – Colorizer now allows you to customize your vehicle even further, with custom patterns, license plates, and tint
  • Navigation Improvements – Easier layout and setup
  • Supercharger Site Map – Starting at 18 pilot locations, a 3D view of the Supercharger you’re visiting will be available
  • Automatic Carpool Lane Routing – Navigation will utilize carpool lanes if enabled
  • Phone Left Behind Chime – Your car will now tell you if you left a phone inside
  • Charge Limit Per Location – Set a charge limit for each location
  • ISS Docking Simulator –  New game
  • Additional Improvements – Turn off wireless charging pad, Spotify improvements, Rainbow Rave Cave, Lock Sound TRON addition

Tesla also added two other things that were undocumented, like Charging Passport and information on USB drive storage to help with Dashcam.

Tesla updates Cybertruck owners about key Powershare feature

Published

Tesla is updating Cybertruck owners on its timeline of a massive feature that has yet to ship: Powershare with Powerwall.

Powershare is a bidirectional charging feature exclusive to Cybertruck, which allows the vehicle’s battery to act as a portable power source for homes, appliances, tools, other EVs, and more. It was announced in late 2023 as part of Tesla’s push into vehicle-to-everything energy sharing, and acting as a giant portable charger is the main advantage, as it can provide backup power during outages.

Cybertruck’s Powershare system supports both vehicle-to-load (V2L) and vehicle-to-home (V2H), making it flexible and well-rounded for a variety of applications.

However, even though the feature was promised with Cybertruck, it has yet to be shipped to vehicles. Tesla communicated with owners through email recently regarding Powershare with Powerwall, which essentially has the pickup act as an extended battery.

Powerwall discharge would be prioritized before tapping into the truck’s larger pack.

However, Tesla is still working on getting the feature out to owners, an email said:

“We’re writing to let you know that the Powershare with Powerwall feature is still in development and is now scheduled for release in mid-2026. 

This new release date gives us additional time to design and test this feature, ensuring its ability to communicate and optimize energy sharing between your vehicle and many configurations and generations of Powerwall. We are also using this time to develop additional Powershare features that will help us continue to accelerate the world’s transition to sustainable energy.”

Owners have expressed some real disappointment in Tesla’s continuous delays in releasing the feature, as it was expected to be released by late 2024, but now has been pushed back several times to mid-2026, according to the email.

Foundation Series Cybertruck buyers paid extra, expecting the feature to be rolled out with their vehicle upon pickup.

Cybertruck’s Lead Engineer, Wes Morrill, even commented on the holdup:

He said that “it turned out to be much harder than anticipated to make powershare work seamlessly with existing Powerwalls through existing wall connectors. Two grid-forming devices need to negotiate who will form and who will follow, depending on the state of charge of each, and they need to do this without a network and through multiple generations of hardware, and test and validate this process through rigorous certifications to ensure grid safety.”

It’s nice to see the transparency, but it is justified for some Cybertruck owners to feel like they’ve been bait-and-switched.
