The electric hypercar realm is witnessing the beginning of an unbelievable hypercar rivalry. Up for grabs is the fastest production car in the world, which is also electric. In one corner is the reigning, defending hypercar champion, Rimac’s Nevera. In the other corner is Tesla's forthcoming Roadster SpaceX Edition.

The Battle for Hypercar Hegemony

Elon Musk's late-night revelations earlier this week have promised a next-generation Roadster that defies conventional automotive norms, particularly with hints at rocket thruster-enhanced performance that will launch the car from 0-60 mph in less than one second. His posts caught much attention, including those of Mate Rimac, CEO of Rimac Automobili.

..it is possible with thrusters. We did the simulation… - Mate Rimac

Rimac is a pivotal figure in the hypercar world, renowned for blending high performance with electric propulsion. When asked about Tesla's audacious acceleration claim, he weighed in with a blend of technical insight and real-world pragmatism. His perspective is not just academic; it's grounded in the tangible realities of engineering and physics that govern high-performance vehicles.

Fast but Heavy, Light but “Slow”

Rimac acknowledged the feasibility of Tesla's target, citing thrusters as a viable means to surpass traditional acceleration benchmarks. However, he underscored the inherent trade-offs, noting the considerable weight of the necessary equipment—tanks, compressors, valves, and nozzles—that, while contributing to initial acceleration, become dead weight after that.

Rimac also points out another flaw: “Plus, the car has to be super light as otherwise, you can’t create a lot of excess downforce with the fans as the tires would be overloaded very fast with any kind of car with “normal supercar” weight, especially electric. And then again, you are carrying the weight with you when you are not doing 0-100. So thrusters are really the only way to go. But it brings a lot of downsides as well.”

Nevera, costing approximately $2.5 million, dominates the scene with more than 1,800 horsepower and its record-shattering performances, including an extraordinary 0-60 mph time of 1.74 seconds and a 0-400 km/h sprint in 21.31 seconds. When Nivera posted these incredible numbers, Musk was asked if the Roadster could beat the time and responded: lol.

Beyond the Numbers

Rimac's acknowledgment of the technical hurdles associated with Tesla's approach does not detract from the potential impact of the Roadster. Instead, it adds a layer of credibility to the discussion, grounding it in the realities of automotive engineering. It's a reminder that the quest for unparalleled acceleration involves balancing the thrill of speed with the practicalities of vehicle design and functionality.

This dialogue between Tesla and Rimac marks a significant moment in the EV industry. Tesla's pursuit of the ultimate performance EV with the new Roadster places it in direct conversation with Rimac. This company has consistently pushed the boundaries of what electric hypercars can achieve. The interaction underscores a broader theme in the automotive world: the relentless pursuit of innovation, where companies like Tesla and Rimac are not just competing but also learning from each other.

With both companies poised to innovate further and redefine what's possible, the rivalry between Tesla's Roadster and Rimac's Nevera is more than a contest of speed—it's a testament to the relentless pursuit of innovation that drives the electric vehicle industry forward. The Roadster is to start deliveries in 2025. Odds are the first place it will be is on the track beside a Nevera!

Is Tesla Planning to Add Steam Support to All Vehicles?

Not a Tesla App

Yesterday, we reported that Tesla updated their Steam integration on Model S and Model X vehicles. The update was part of their 2024 Holiday Update, but it looks like there may be more to this than a simple update.

Steam, a video game library app, makes it easy for users to buy or launch games on their computers. However, a couple of years ago, Valve, who created Steam, launched their own standalone device, the Steam Deck. The Steam Deck runs a custom OS based on Linux.

Steam Launch

When Tesla launched the redesigned Model S and Model X, Tesla introduced a dedicated gaming GPU with 16GB of RAM and touted the ability to play top-tier PC games in Tesla vehicles.

In 2022, Tesla finally launched the Steam app for the Model S and Model X as part of its 2022 Holiday Update. The Steam app runs Steam OS, the same OS as the Steam Deck in a virtual environment.

However, earlier this year, Tesla stopped including the GPU and Steam (Beta) in their vehicles, and we haven’t seen any updates to the Steam in quite some time. In fact, we thought Tesla was axing their gaming-on-the-go dreams.

SteamOS Update

The Steam app, which is still in Beta, is getting an interesting update for the Model S and Model X vehicles with the discrete GPU.

Those vehicles received an update to SteamOS 3.6 - the same version of SteamOS that runs on the Steam Deck. While nothing has visually changed, there’s a long list of performance optimizations under the hood to get things running smoother.

Comparing Steam Deck to Tesla Vehicles

Let’s take a look at the Steam Deck - according to Valve, its onboard Zen4 CPU and GPU combined push a total of 2 TFlops of data, which is fairly respectable, but much lower than today’s home consoles. The Steam Deck is capable of 720p gaming fairly seamlessly on low-to-medium settings on the go and is also built on the AMD platform.

AMD-equipped Teslas, including the Model 3 and Model Y, are packing an older Zen+ (Zen 1.5) APU (processor with a combined CPU and GPU). AMD claims that the V1000 - the same embedded chip as on AMD Tesla vehicles (YE1807C3T4MFB), brings up to 3.6 TFLops of processing power with it, including 4K encoding and decoding with the integrated GPU on board.

While that’s not enough for 4K gaming or comparable to a full-blown console or desktop GPU, that’s enough raw horsepower for light gaming and is currently more powerful than the Steam Deck.

The Model S and Model X’s GPU brings that up to about 10TFlops of power - comparable to modern consoles like the Xbox Series X at 12 TFlops.

Steam Gaming for All Vehicles?

The fact that Tesla is updating SteamOS even though the feature is no longer available in any new vehicles could indicate that Tesla is not only bringing Steam back to Teslas but that it’s going to play a much bigger role.

While SteamOS is run in a virtual environment on top of Tesla’s own OS, we could see Tesla bring SteamOS to all of its current vehicles, including the Model 3, Model Y, and Cybertruck. Steam in these vehicles would likely support any game that’s capable of running on the Steam Deck.

We think this Steam update, which includes performance improvements and a variety of fixes, has quietly passed under most people’s radars. This could be a very exciting update for those who enjoy gaming, especially for those who love to do it in their Tesla.

Tesla Holiday Update Weather Features: All the Small Details

As part of Tesla’s 2024 Holiday Update, Tesla included two awesome new features - Weather at Destination and the long-awaited Weather Radar Overlay. These two features are big upgrades built upon the weather feature that was added in update 2024.26. The original weather feature added an hourly forecast, as well as the chance of precipitation, UV index, Air Quality Index, and other data.

However, this update also added some smaller weather touches, such as the vehicle alerting you if the weather at the destination will be drastically different from the current weather.

Weather At Destination

When you’re navigating to a destination and viewing the full navigation direction list, the text under the arrival time will show you the expected weather next to your destination. You can also tap this, and the full weather pop-up will show up, showing your destination's full set of weather information.

Note the weather under the arrival time

You can also tap the weather icon at the top of the interface at any time and tap Destination to switch between the weather at your current location and the weather at your destination.

You’re probably considering that the weather at your destination doesn’t matter when you’re three hours away - but that’s all taken into account by the trip planner. It will add in both charge time and travel time and show you the weather at your destination at your expected arrival time.

And if the weather is drastically different or inclement, such as rain or snow, while you’ve got sunshine and rainbows - the weather will be shown above the destination ETA for a few moments before it tucks itself away.

Tesla also recently introduced a new voice command. Asking, “What’s the weather?” or something similar will now bring up Tesla’s weather popup.

One limitation, though—if you’re planning a long road trip that is more than a day of driving, the weather at destination feature won’t be available until you get closer.

Weather Radar Overlay

As part of the improvements to weather, Tesla has also added a radar overlay for precipitation. You can access the new radar overlay by tapping the map and then tapping the weather icon on the right side of the map. It’ll bring up a radar overlay centered on your vehicle. It’ll animate through the radar data over the last 3 hours so that you can see the direction of the storm, but you can also pause it at any point.

You’re able to scroll around in this view and see the weather anywhere, even if you zoom out. It also works while you’re driving, although it can be a little confusing if you’re trying to pay attention to the navigation system. If you like to have Points of Interest enabled on your map, the weather overlay will hide POIs except for Charging POIs.

Requirements / Data

Unfortunately, you’ll need Premium Connectivity for any of the weather features to work, and being on WiFi or using a hotspot will not be enough to get the data to show up. The data, including the weather radar, is provided by The Weather Channel.

As for supported models, weather and weather at destination are available on all vehicles except for the 2012-2020 Model S and Model X. The weather radar has more strict requirements and requires the newer AMD Ryzen-powered infotainment center available on the 2021+ Model S and Model X and more recent Model 3 and Model Y vehicles.
