Tesla’s Model 3 Heat Pump is a game changer compared to its old system

Tesla’s addition of a Heat Pump to its 2021 Model 3 was installed with the intention of bringing owners of the company’s most affordable vehicle more range and more efficiency. Now that the newly “refreshed” Model 3 is making its way to owners, it is proving to be around three times more efficient than older builds of the vehicle.

A new video from well-known EV content creator and Tesla owner Bjørn Nyland showed that the heat pump gives owners around three times the efficiency compared to the previous HVAC system, which used a Positive Temperature Coefficient, or PTC system. This proves the addition of the heat pump was a strategy that will end up paying dividends to owners in cold climates, especially now as the Winter months are making their way to many owners across the U.S. and European markets.

Nyland compared a brand new 2021 Model 3 to his older version of the car, which does not have a heat pump equipped. Performing stationary tests to see which system was more efficient in heating up the vehicle during a chilly December night was the perfect test in Nyland’s eyes, and he came out of it with results that proved Tesla’s new system was superior to the old one.

Nyland used Camp Mode to test the efficiency of the two cars. Camp Mode maintains a temperature in the cabin while the vehicle is stationary and is ideal for those who sleep in their cars overnight. Because it uses energy from the car’s battery to maintain a comfortable cabin temperature, it was ideal for it to be used during this testing scenario.

After three hours of heating the cabin, both vehicles showed a drop in the state of charge, of course. However, the differences in the drop were night and day. The heat pump-equipped 2021 Model 3 had dropped only 3% in the three-hour span, while the sedan’s pre-heat pump variant had lost 10% of its battery.

The 2021 Model 3 has a 73.5 kWh battery pack with little-t0-no degradation due to its new powertrain that had only 65 kilometers on it. It used only 735 W of energy per hour, meaning 2,205 W were used over the course of the test.

The older Model 3 evidently did not have the efficiency that the new, heat pump-outfitted Model 3 did. After starting at 56%, the three hours of heating the cabin had brought the car’s state of charge down to 46%, meaning it was using roughly three times the amount of energy that the heat pump did. This equated to 2170 W of energy being used per hour by the old Model 3.

It is no secret that using a heat pump is more efficient than the past PTC HVAC system was. Tesla installed the heat pump in the Model Y and made it standard upon the car’s first deliveries in March 2020. Tesla decided to then make it standard in the Model 3 after refreshing the car in October 2020.

More tests are likely to come that will compare the two systems, but this test shows the efficiency differences in the two cars while heating up. If you’re spending nights in your Model 3, the new 2021 variant may be the way to go to alleviate any concerns about range diminishment overnight.

Tesla launches 200mph Model S “Gold” Signature in invite-only purchase

Tesla’s final 350-unit Signature Edition closes the book on two cars that changed everything.

Published

Tesla has announced a super limited Signature Edition run of 250 Model S Plaid and 100 Model X Plaid units as an invite only purchase in a bid to give its original flagship vehicles a proper send-off.

When the Model S first launched in 2012, the first 1,000 units sold were “Signature” editions that required a $40,000 deposit and cost nearly $100,000 each. Those early buyers were Tesla’s first real believers. This new Signature Edition deliberately echoes that moment, bookending a 14-year run with numbered collector hardware.

Both models are finished in an exclusive Garnet Red paint not available on any current Tesla production vehicle, with gold Tesla T badges up front, a gold Plaid badge and Signature badge at the rear, and a white Alcantara interior featuring gold Plaid seat badges, gold piping, Signature-marked door sills, and a numbered dash plate. The Model S adds carbon ceramic brakes with gold calipers. Every unit ships with Tesla’s Luxe Package, bundling Full Self-Driving (Supervised), four years of Premium Service, free lifetime Supercharging, and a Signature Edition key fob. Both are priced at $159,420, a roughly $35,000 premium over standard Plaid inventory.

The discontinuation is part of a broader strategic shift. At Tesla’s Q4 2025 earnings call, Musk described the decision as “slightly sad” but necessary, saying: “It’s time to basically bring the Model S and X programs to an end with an honorable discharge, because we’re really moving into a future that is based on autonomy.”

Tesla FSD in Europe vs. US: It’s not what you think

Tesla FSD is approved in the Netherlands, but the European version differs from what US drivers use.

On April 10, 2026, the Dutch vehicle authority RDW granted Tesla the first European type approval for Full Self-Driving Supervised, making the Netherlands the first country on the continent to authorize Tesla’s semi-autonomous system for customer use on public roads.

As Teslarati reported, the RDW approval followed 18 months of testing, more than 1.6 million kilometers driven on EU roads, 13,000 customer ride-alongs, and documentation covering over 400 compliance requirements. Tesla Europe had been running public demo drives through cities like Amsterdam and Eindhoven since early 2026, giving passengers their first experience of the system on European streets.


The European version of FSD is not the same software US drivers use. The RDW’s own statement is direct, noting that the software versions and functionalities in the US and Europe “are therefore not comparable one-to-one.” We’ve compile a table below that captures the most significant differences between US-based Tesla FSD vs. European Tesla FSD that’s based on what regulators and Tesla have publicly confirmed.

Feature FSD US FSD Europe (Netherlands)
Regulatory framework Self-certification, post-market oversight Pre-market type approval required (UN R-171 + Article 39)
Hands requirement Hands-off permitted on highway Hands must be available to take over immediately
Auto turning from stop lights Available — navigates intersections, turns, and traffic signals autonomously Available in EU build — confirmed in Amsterdam demo footage handling unprotected turns and signalized intersections
Driving modes Multiple profiles including a more aggressive “Mad Max” mode EU build is more conservative by default and errs on the side of restraint when it cannot confirm the limit
Summon Available — Smart Summon navigates parking lots to driver Status unclear — not confirmed as part of the RDW-approved feature set; urban FSD approval targeted separately for 2027
Driver monitoring Camera-based eye tracking Stricter continuous monitoring with more frequent intervention alerts
Software version FSD v14.3 EU-specific builds that must be separately validated by RDW
Geographic restriction US, Canada, China, Mexico, Australia, NZ, South Korea Netherlands only; EU-wide vote pending summer 2026
Subscription price $99/month €99/month
Full urban FSD scope Available Partial — separate urban application planned for 2027

The approval comes as Tesla is under real pressure to grow FSD subscriptions globally. Musk’s 2025 CEO compensation package, approved by shareholders, includes a milestone requiring 10 million active FSD subscriptions as one condition for his stock awards to vest. Tesla hit one million subscriptions during its Q4 2025 earnings call, which is a meaningful start, but still a long way from the target. Opening Europe as a market for subscriptions, rather than just hardware sales, directly accelerates that number.

Tesla has said it anticipates EU-wide recognition of the Dutch approval during summer 2026, which would extend FSD access to Germany, France, and other major markets through a mutual recognition process without each country repeating the full 18-month review. That timeline is Tesla’s projection, not a confirmed regulatory outcome. As Musk acknowledged at Davos in January 2026, “We hope to get Supervised Full Self-Driving approval in Europe, hopefully next month.”

Tesla’s troublesome Auto Wipers get a major upgrade

Tesla has quietly deployed a major over-the-air (OTA) update across its entire fleet, implementing a new patent that could finally solve one of the most complained-about features in its vehicles: the Auto Wipers.

One of Tesla’s most complained-about features is that of the Auto Wipers, but they have recently received a major upgrade that impacts every vehicle in the company’s fleet, a company executive confirmed.

Tesla has quietly deployed a major over-the-air (OTA) update across its entire fleet, implementing a new patent that could finally solve one of the most complained-about features in its vehicles: the Auto Wipers.

Confirmed by senior Tesla AI engineer Yun-Ta Tsai on April 10, the improvement is based on patent US 20260097742 A1. It introduces an “energy balance model” that adds a tactile, physics-driven layer to the existing camera-based system—without requiring any new hardware.

Tesla drivers have griped about auto wipers since the company ditched traditional rain sensors in favor of Tesla Vision around 2018.

Owners routinely report the wipers failing to activate in light drizzle or mist, leaving windshields streaked and visibility dangerously reduced. Just as often, they formerly blasted into high-speed mode on dry, sunny days, screeching across glass and risking scratches or premature blade wear.

This is a rare occurrence anymore, but many owners still report the feature having the wipers perform at the incorrect speed or frequency when precipitation is falling.

Tesla has tried repeatedly to fix the problem through software alone.

Early “Deep Rain” initiatives and the 2023 Autowiper v4 update used multi-camera video and refined neural networks, with Elon Musk promising “super good” performance. The 2024.14 update added manual sensitivity boosts, and later FSD versions claimed further gains. Yet complaints persisted.

Vision systems struggle with edge cases—glare, bugs, reflections, or faint mist—because they rely purely on visual inference rather than physical detection

The new patent takes a different approach. The car’s computer constantly measures electrical power delivered to the wiper motor. It subtracts predictable losses—internal motor friction, linkage drag, and aerodynamic resistance—leaving only the friction force between the rubber blade and windshield glass.

Water lubricates the glass, sharply reducing friction; dry or icy surfaces increase it dramatically. This real-time “tactile” data acts as an independent check on the camera’s visual cues, instantly shutting down false triggers on dry glass and fine-tuning speed for actual rain.

The system can also detect ice and auto-activate defrost heaters, while long-term friction trends alert drivers when blades need replacing.

By fusing vision with precise motor-load physics, Tesla has created a hybrid sensor that is both elegant and cost-free. Owners have waited years for reliable auto wipers; this OTA rollout may finally deliver them.
