Porsche Taycan’s repeatable performance claims put to the test by veteran drag racer
When Porsche launched the Taycan last year, its message was clear. It’s an all-electric performance car built for the track. You can take it with a battery half charged and you’ll still get the same level of performance you’d expect at full charge. At least that’s what Porsche promises.
DragTimes YouTube channel host and Tesla owner Brooks Weisblat recently put the Taycan Turbo’s repeatable performance claim to a real-world test. He took a Taycan Turbo and the more powerful Turbo S out on the track to see how they would perform launching from 0 to 60 mph and covering the 1/4 mile.
Weisblat specifically asked the engineers at Champion Porsche in Pompano Beach, FL to have both cars ready at full charge. However, while the Turbo had a 91% charge when he arrived, while the Turbo S was only at 57%. This presented a unique opportunity to test just how well the vehicles performed with such discrepancy in their battery levels.
At just a little bit more than half charge, the $185,000 Turbo S went from 0 to 60 mph in 2.67 seconds and ran a quarter-mile at 124 mph. It’s impressive for an all-electric vehicle but not so much for one housing the world’s first two-speed gearbox in an electric car.
“I kind of expected it to be a little better especially given it having the transmission,” Weisblat says. “I was expecting track speeds near 130 mph. The launch I wasn’t so sure because Porsche’s claiming it does 0 to 60 in 2.8 seconds.”
Previous testing done by DragTimes shows the Tesla Model S with a 96 percent charge can go from 0 to 60 mph in 2.45 seconds. That’s a couple of tenths of a second faster than the Turbo S, which has acceleration and speed advantages due to its two-speed transmission.
The Turbo, which has 90 less horsepower than the Turbo S, went from 0 to 60 mph at 2.8 seconds. It’s not as fast as the Turbo S but it’s nothing to scoff at. But here’s the kicker. After the first 60 mph, the Turbo S didn’t have much of an advantage over the less powerful Turbo. If the state of charge doesn’t matter as Porsche says, the Turbo should have at least similar or less performance.
But Weisblat’s testing shows the Turbo at 91% charge went from 60 to 100 mph in 8.41 seconds and took the 1/4 mile at 127 mph. That’s a whole 3 mph faster than the Turbo S, which was at 56% charge when testing began. Had both cars been raced against each other, the Turbo would have won hands down over the Turbo S. Weisblat also says that both Turbo and Turbo S used up about 2% of the battery after each 1/4 mile.
“State of charge does matter with the Porsche. There’s no question about it. Because the Taycan Turbo S sitting at 56 percent is tracking at 124 mph. The Turbo at 91 percent is going 3 mph faster. For those of you who don’t know about road racing or drag racing, that is a significant difference,” he said.
The results would have been different had both cars been charged fully. Weisblat estimates the Turbo S could go the 1/4 mile at 130 mph and launch from 0 to 60 mph at around 2.5 seconds so that it’s right in line with the Tesla Model S. However, he believes that the Turbo S would further drop to 7 seconds once it goes from 60 to 130 mph, just up to par with a Lamborghini Huracan. If so, he says the Model S could be “in trouble,” at least when you take it down to the race track.
To maintain these numbers, Porsche has to keep the Taycan’s battery at optimal temperatures using a unique battery thermal management system. Unfortunately, because the car relies purely on electricity, the Taycan uses up extra energy from the battery just to maintain its energy-intensive temperature control system.
It’s a double-edged sword, especially for an electric vehicle. Porsche had to sacrifice a few things in exchange for performance. A lot of people weren’t happy to hear that the EPA gave the Taycan Turbo S a range rating of 192 miles. The Taycan Turbo didn’t do much better at 201 miles, which is 182 whole miles less than the 373 miles of the Model S Long Range.
But then again, the Taycan isn’t exactly made for most people. In fact, with a six-figure price tag and the Porsche logo on its hood, it’s not even made for mainstream EV buyers. And it’s a good thing for the electric car market as a whole.
Tesla has launched a direct campaign targeting its customers in New Jersey, sending emails that warn of pending legislation that could effectively block true driverless technology in the state.
The email focuses on Senate Bill S.1677 and Assembly Bill A.3968, measures intended to create a three-year autonomous vehicle pilot program but laden with requirements that Tesla argues make unsupervised Robotaxis impossible.
Tesla is sending out this email to New Jersey Tesla owners, warning them that NJ could block autonomous vehicles, and to take action.

According to the email, the bills impose “restrictions so severe that true driverless deployment would remain illegal.” Specific hurdles include mandates for human safety drivers during operations, multimillion-dollar insurance minimums, reportedly $5 million, and thresholds like 100,000 miles of demonstrated safe autonomous driving before any driverless approval.
Tesla contends these are arbitrary barriers that ignore real-world performance data and favor entrenched competitors over innovative technologies like its Full Self-Driving (FSD) system.
The push comes as Tesla has started expanding Robotaxi operations in states like Texas, where unsupervised vehicles are already providing rides in several cities. New Jersey, by contrast, risks falling behind. The company highlights in the email communication that more than 94 percent of serious crashes result from human error, meaning impairment, distraction, or fatigue. These are all problems that Robotaxis eliminate entirely.
In 2025, New Jersey recorded 582 traffic deaths, underscoring the human cost of delayed adoption.
Tesla’s outreach stresses the transformative potential of robotaxis. For families, they could offer safer school runs without drowsy or distracted drivers. For seniors and people with disabilities, robotaxis promise independence and reliable mobility.
In areas with limited public transit, they could deliver affordable, on-demand transportation, reducing congestion, emissions, and overall transportation costs. Economically, the company warns that restrictive rules could cost New Jersey jobs, innovation investment, and billions in potential growth as autonomous ride-hailing scales elsewhere.
Supporters of the legislation, including Sen. Andrew Zwicker, describe the pilot as a cautious framework with strong safety oversight, including incident reporting, expert task forces, and restrictions in sensitive zones like school areas. They view it as balancing innovation with public protection.
Tesla and pro-AV advocates counter that the bill lacks technology neutrality, creates insurmountable entry barriers for commercial deployment, and prioritizes process over outcomes — effectively functioning as a de facto ban on services like Robotaxi.
This latest clash echoes Tesla’s past battles in New Jersey over direct vehicle sales. The email directs owners to Tesla’s advocacy platform, where they can send customized messages to legislators calling for amendments: outcome-based safety standards, open competition, and clear pathways for fully driverless commercial operations.
As hearings approach, Tesla’s campaign frames the issue as a choice between protecting the status quo and embracing life-saving progress. With robotaxi technology already proving itself in permissive states, New Jersey owners are being asked to ensure their state doesn’t lock out the future of transportation.
Turn-by-turn navigation is not new technology.
For over two decades, drivers have relied on Garmin, TomTom, and later smartphone apps like Google Maps and Waze to receive precise, reliable directions. These systems have guided millions safely through unfamiliar cities, highways, and backroads with remarkable effectiveness. They handle real-time traffic, construction detours, and complex intersections with minimal fuss.
Yet Tesla, the company that promised revolutionary Full Self-Driving (FSD), continues to struggle with this foundational capability. As FSD (Supervised) v14.3.4 has started rolling out to cars this week, navigation remains its glaring Achilles’ heel, undermining the entire autonomous vision.
Tesla Summon got insanely good in FSD v14.3.2 — Navigation? Not so much
Tesla’s FSD excels in many driving behaviors—smooth acceleration, confident lane changes in ideal conditions, and responsive handling of visible obstacles. However, when it comes to following a route accurately, the system falters repeatedly.
Owners report wrong turns, missed exits, inefficient routing through local roads instead of highways, phantom speed limit errors, and even directing vehicles to building rear entrances. Interventions for navigation issues often outnumber those for core driving maneuvers. Tesla has begun surveying owners specifically about these errors, acknowledging the problem after years of complaints.
Navigation is perhaps my biggest complaint when it comes to FSD, because sometimes, we do know better. Some of us have been living in our areas for our entire lives, but even those who have not have years or even decades of experience driving on local roads. We might know a little better about routing.
But the navigation mistakes are more than just FSD potentially taking a slightly different route that may or may not save you a few minutes. Sometimes, they’re genuinely mind-boggling.
This isn’t just annoying; it cascades into broader failures. A flawed route plan confuses the AI’s decision-making, leading to hesitant behavior, unnecessary disengagements, or dangerous maneuvers like attempting impossible U-turns or ignoring clear ramps. In a system meant to operate with minimal supervision, unreliable navigation erodes trust.
More often than not, false or plain incorrect navigation is what causes me to interrupt FSD operation. Unfortunately, I believe the latest FSD version is the worst example of it, and it leads me to believe that Tesla might be making some changes; they’ve just made them in the wrong direction.
It makes you wonder: Why is a company that has done so much with the progress of FSD and autonomy struggling so much with navigation, something that is not new and has been around a long time?
Multiple Data Sources
First, Tesla’s navigation relies on a fragile patchwork of multiple data sources—Google Maps, TomTom, OpenStreetMap, Valhalla, and its own fleet-derived data—stitched together rather than a single authoritative map. When these conflict on lane geometry, road status, or turn details, the system hesitates or chooses incorrectly.
Traditional GPS providers maintain centralized, regularly validated databases with professional curation and rapid updates. Tesla’s hybrid approach, while innovative in crowdsourcing, introduces inconsistencies that a purely vision-based or end-to-end AI approach may not easily reconcile in real time.
Persistent Learning
FSD seems to struggle with persistent learning from driver interventions.
Unlike consumer apps that quickly adapt to repeated corrections or user preferences (e.g., avoiding certain routes or remembering habitual detours), Tesla’s FSD often fails to internalize fixes on the same trip or across similar scenarios. Owners note making the same manual override multiple times without the routing engine updating its behavior meaningfully.
This stems from the neural architecture prioritizing real-time perception and control over long-term route memory and personalization, making navigation feel rigid and “opinionated” compared to the adaptive logic in Waze or Google Maps.
I noticed that when I asked Grok to try and get me home a certain way (a way that FSD routinely took in the past because it was the most efficient), it had to place a waypoint between my location at the time and my house. When I went to edit the waypoint out, as Grok had placed it for a way to get FSD to get off the highway at the right exit, it was stumped again, rerouted, and took a longer way home.
The next thing I’ve noticed, and this might be controversial, is that Nav has gotten even worse.
I think that might actually be a good thing; Tesla seems to be adjusting it. They just need to adjust it the opposite way.

Reasoning, Scaling, and Intuition
Third, scaling navigation for unsupervised or robotaxi ambitions requires not just accuracy but adaptability and user-like reasoning. Current FSD often defaults to single routes that ignore driver preferences or real-world nuances like time-of-day traffic patterns. It fails to match the intuitive, context-aware planning that traditional systems have refined over the years.
Resolving navigation is critical for several reasons. Practically, it is the backbone of any autonomous journey: without trustworthy routing, the car cannot reliably reach destinations, rendering FSD useless for robotaxis or hands-free commutes. Safety depends on it—mismatched plans create hesitation in merges or intersections, increasing accident risk.
Economically, Tesla’s valuation and future hinge on FSD delivering unsupervised driving; persistent navigation flaws delay regulatory approval and erode consumer confidence. For owners who paid premiums for FSD, these issues represent unfulfilled promises. While it is unlikely Tesla will lose too many customers due to bad navigation, some will be frustrated with the constant need for human input.
Tesla has achieved miracles in electric vehicles and battery tech. Mastering turn-by-turn—technology Garmin nailed in the early 2000s—should not be this hard. By investing in tighter data integration, faster learning loops from interventions, and more intuitive routing algorithms, Tesla could close this gap.
Until then, FSD’s navigation struggles highlight a humbling truth: even the most ambitious innovator must sometimes master the basics before conquering the future.
A Tesla Cybertruck driver in the United Kingdom had their all-electric pickup seized by local police in the Greater Manchester area after the department cited “legitimate concerns.”
Last Thursday, police saw the pickup on the roads and decided to pull the driver over. Greater Manchester Police said:
“Whilst this may seem trivial to some, legitimate concerns exist around the safety of other road users or pedestrians if they were involved in a collision with the Cybertruck.”

The Cybertruck in question was, according to the BBC, registered and insured abroad and was confiscated. The driver, who is a UK resident, was reported.
The Greater Manchester Police Department then added:
“The Tesla Cybertruck is not road-legal in the UK and does not hold a certificate of conformity.”
The Cybertruck cannot be legally driven in the UK because it has no UK Type Approval for operation in the country. This is due to some safety concerns, which are related to its angular shape and design. The stainless steel exoskeleton has sharp edges and projections that violate UK/EU rules on pedestrian protection.
Tesla has considered creating what it referred to as an “international version” that would be approved for operation in Europe. However, there has been no real movement on that front by the company, as it has been focused on the Robotaxi rollout primarily.
