The Porsche Taycan’s formal unveiling is only a couple of days away, and the German sports car maker is on full throttle in its efforts to drum up excitement for what could very well be its most important vehicle in decades. Among the most recent of these is a unique acceleration and braking test, which just so happened to be conducted on the flight deck of a US aircraft carrier.
For its test, Porsche opted to utilize the USS Hornet as the runway for the Taycan’s test. The ship is massive, displacing over 27,500 tons and fitted with an 869-foot flight deck. Apart from its long history of active service, the USS Hornet also has the distinction of being the ship that recovered the astronauts from the Apollo 11 and 12 Moon missions.
Porsche tapped the talents of professional racer Shea Holbrook for the Taycan’s test. Conventional acceleration and braking tests usually feature vehicles accelerating from 0-60 mph, then braking hard to decelerate from 60-0 mph. Since the Taycan is no conventional vehicle, Porsche opted to up the ante. Instead of 0-60 mph, the Taycan accelerated to 90 mph before braking hard and decelerating to zero.
This makes the test particularly tricky, considering that it’s pretty much open sea after the vehicle covers the USS Hornet’s flight deck. Fortunately, the Taycan proved capable, accelerating from a standstill to 90.58 mph in 422 feet before braking hard. The entire run took 10.17 seconds.
Speaking about the experience, the veteran female racer noted that the car performed well considering the constraints of the USS Hornet. Holbrook noted that the vehicle proved stable and composed, despite the uneven surface of the carrier’s deck.
“The deck is a long, long way up and despite appearances, it’s actually quite bumpy. Deliberately accelerating towards thin air and the ocean is a new experience for me, but the Taycan gave me a huge amount of confidence – it was really stable but under acceleration and, more importantly, under braking. I built up to the final run, slowly increasing the speed each time until I felt confident and each time the car felt completely comfortable in what it was being asked to do. What a rush!” she said.
Stefan Weckbach, Vice President for the Taycan’s Product Line, stated that the unconventional test was a good, fun way of demonstrating the power of the upcoming vehicle. The Porsche executive candidly added that he was just glad no one ended up taking an unexpected swim due to the test.
“While this isn’t a usual metric we use to benchmark the performance of the Taycan and rather some kind of fun testing than a completely serious one, it’s quite a fitting way to demonstrate the power of the car as it nears the end of its development. On a tough, changeable surface the Taycan’s composure, its incredible acceleration and stopping power were absolutely impressive – though we decided not to take it to the max, just to reach the 0-100 mph margin. While I was completely sure both Shea and the car could achieve something special, I’m really relieved no one went for a swim,” he said.
The production version of the Porsche Taycan is set to be formally unveiled in three countries later this week; one in Canada, one in Germany, and another in China. The event will begin on September 4, 2019 at 9 a.m. EST.

Tesla revealed a major new Cybercab detail in a guide it released for First Responders, showing new territory in its beliefs and intentions for the ride-hailing-focused vehicle that entered production in April.
The First Responders Guide is released to give fire departments, paramedics, and other emergency personnel the proper guidance on what to do in the event of an accident, entrapment, or other situation that would require immediate attention.
On one of the pages of the First Responders Guide, Tesla revealed a stark detail about the Cybercab, which could help personnel enter the vehicle more easily in case of an emergency.
Tesla Cybercab has one important piece that AI4 cars might need for FSD
It shows Tesla has no intention of releasing any Cybercab units that were initially proposed for ride-hailing services for the general public with any manual controls, meaning a steering wheel or pedals:
“A Cybercab equipped with steering wheel, brake pedal, and an acceleration pedal is typically an engineering or test vehicle, and operates at SAE Level 2 autonomy. Cybercab is not typically equipped with a steering wheel or acceleration and brake pedals.”

This is a major development for those who continue to believe Tesla planned to release the Cybercab with any sort of manual controls so that passengers could take over if needed. However, when Tesla started manufacturing production versions of the Cybercab in Giga Texas earlier this year, they were spotted without a steering wheel or pedals.
It essentially confirms the company has no intentions of bringing manual controls to the car’s production versions. Some have argued that the likelihood of Tesla having something
There still are some Cybercab units out there with a steering wheel and pedals, and as Tesla said, these cars are engineering or test vehicles, which have Safety Monitors on board to help the car out of a precarious situation or emergency.
Tesla released the Full Self-Driving v14 ‘Lite’ suite to owners of Hardware 3 or AI3 vehicles today, adding several new features to the vehicles that were once believed to be capable of unsupervised self-driving.
Now, Tesla has released this modified suite to older Tesla vehicles, adding plenty of new features and capabilities.
Here are the full release notes for the suite:
- Distilled the intelligence from HW4 V14 into HW3. This allows HW3 to directly learn how to handle scenarios using HW4 V14 as a guide. This process unlocks the improvements that have been made to HW4 including Reinforcement Learning (RL) and offline models for HW3.
- Improved both proactive and reactive responsiveness across a wide variety of categories including navigation handling, merges and forks, pedestrian interactions, traffic lights, and vehicle cut-in scenarios.
- Improved general comfort in nominal scenarios through fewer false slowdowns, smoother steering and more consistent lane centering.
- Introduced parking, unparking, and reversing capabilities.
- Added Arrival Options for you to select where FSD should park: in a Parking Lot, on the Street, in a Driveway, or at the Curbside.
- Speed Profiles are now available at all times, to further customize driving style preference.
These improvements, according to Tesla’s Head of AI, Ashok Elluswamy, help distill the driving behavior from AI4’s v14 series into both the camera and compute configurations of AI3.
Tesla Full Self-Driving v14 ‘Lite’ for older cars finally gets released
He added:
“It includes destination options and speed profiles on city roads, but more importantly significantly improved safety. We hope you’ll enjoy it, once the build ships wide.”
FSD v14 Lite is now rolling out to AI3 early-access customers. Based on the feedback, will rollout to more customers over the next few weeks.

Tesla will continue to roll out the v14 Lite suite more widely in the coming weeks, the company said.
Tesla has finally released its Full Self-Driving v14 ‘Lite’ suite for older cars that equip the Hardware 3 or AI 3 chip, which have not been able to handle the newest versions of the company’s driver assistance software.
Tesla officially started releasing the v14 Lite suite to owners in the Early Access Program last night. The company’s Head of AI, Ashok Elluswamy, said that the rollout will continue over the next few weeks. The build distills the driving behavior from AI4’s v14 series into both the camera and compute configurations of an AI3 car.

It also includes a variety of new features that were available to AI4 cars running v14, including:
- Start Self-Driving from Park
- Arrival and Parking Options
- Speed Profiles
The release is highly anticipated because those owners with AI3 vehicles were early adopters into the FSD platform and were promised that their cars would be capable of achieving Full Self-Driving.
However, Tesla CEO Elon Musk admitted during the company’s recent Q1 Earnings Call that these vehicles would not be capable of achieving unsupervised Full Self-Driving, which is what Tesla had originally said.
Owners were not pleased with this answer, or the idea that their commitment to buying the suite outright for thousands of dollars would not yield the ability to drive without operating the car. Tesla gave some solutions for this, including a discount on a new car, or an upgrade to an AI4 or AI5 self-driving computer and new, upgraded cameras.
Tesla owners do not seem pleased with these options, as they require giving the company more money.
Nevertheless, it is important to note that Tesla came through for owners here by releasing v14 Lite before the end of Q2, something it had promised owners during the previous Earnings Call. Tesla has had trouble keeping up with timelines, but this is a big achievement for the team.
