When the Performance Data Recorder came out on the 2015 Corvettes, we thought it was about the coolest thing ever. Finally, an in-car camera system that records your driving exploits and saves them on a SD Card. Over the years, the system’s telemetry and cameras have greatly improved and today, the Performance Data Recorder not only captures your heroic driving at the track as it can also be set up to automatically record your day-to-day travels as traffic camera.
According to legend, the PDR was the brainchild of former Corvette Product Marketing Manager Harlan Charles who based the interface design from a PlayStation video game. The Performance Data Recorder records your driving from a front facing camera above the rearview mirror and adds telemetry data that includes speed, throttle and brakes, g-forces, a tachometer, and even track overlays. The videos are stored on a flash card inside the glove box.
Up through the 2025 model year, the Corvette’s PDR merged the telemetry with the video so all you had to do was pop the SD Card out the car, put it in your computer, and then you could view your driving exploits with all the information as it was selected from the PDR at the start of recording. However, according to some new 2026 Corvette owners, that process has been changed.
A member of the MidEngineCorvetteForum.com details the changes after picking up a C8 Z06 last month. After his break-in miles were achieved, the member took to the car to an autocross event. But when he got home and popped the SD Card into his computer, only the video was present. He put the card back into the car and when he watched it on the PDR, the telemetry data was there.

So what gives?
Turns out that we have another change for 2026 that General Motors apparently forgot to mention to its most enthusiastic customers. Viewing the PDR telemetry outside the car is now a multi-step process which also requires the use of the free Cosworth AliveDrive App.
We reached out to our friends at Chevrolet about these changes and they confirmed the process to view the telemetry overlay does require the new Cosworth app. Once you have the videos on your device and viewable within the app, you can generate an MP4 video file with the overlay permanently displayed. While the AliveDrive app does require either IOS or Android, owners will also have access to the Cosworth Pi Toolbox. Chevy describes this app as “a powerful data analysis tool that our engineers use for analysis during development and akin to what race teams use to evaluate their own performance.” And finally, our Chevrolet rep says to expect a desktop solution soon as well.
As for the process of getting those videos transferred to your phone and back, a member of the MECF has outlined the process you need to follow. I use Dropbox to move files back and forth from my iPhone to my desktop, but use whatever solution you find best for transferring files between the devices:
Steps to use the Cosworth AliveDrive app:
• Remove SD card from car
• Import videos to phone/tablet
• Import video into AliveDrive app
• Make any edits (as needed)
• Export video from AliveDrive to device
• Copy file from device to destination of your choice
We thank our friends at Chevrolet for diving into this for us and answering our questions. My personal feeling on this is that it was Cosworth that most likely made the changes as they are sharing new software for use with this process. The older Cosworth Toolbox is not available for Windows 11, so it appears that Cosworth is moving on from it.
Still, as one user put it on MECF, most of us are only using the PDR as a dashcam, and the fact that it only shows the video outside the car may save you from additional culpability in the event you want to use it to prove someone else was at fault.
What does the Corvette Nation think about the PDR and the new process to extract the videos with data? Let us know in the comments below!

The 2026 PDR situation is absolute garbage! I have no idea why they did this. My 2016 Stingray PDR worked like a champ. For those who say “we just use it as a dashcam”, here are some points:
1. The dashcam in my truck shows speed, date/time, and GPS location OVERLAID with the video. The videos would be pretty useless without that info.
2. It does this in 4K video for the front camera, and 2K for the rear, significantly higher resolution than the PDR.
3. It cost me $220, slightly less than the PDR I’d wager.
I’ll probably never track my 2026 and I’ll probably never use the PTM modes, but I paid for that. If PTM didn’t work I wouldn’t dismiss it as “well most of us don’t track our cars”. And I would never presume to speak for “most of us”. It’s pretty disappointing that it doesn’t work like the previous 11 model years!
Oh and I see no way of exporting video from AliveDrive.
If Cosworth is not going to update for Windows 11, where does that leave? The people who do look at the track video on the old version of the PDR? How will we view our video in the future?
Adding this step provides ZERO “value added”. Just an additional step where something can go wrong and requires even more space taken up with apps that sometimes work and too often don’t.
GM just fired their software guy they got form Apple. So they must know something is wrong.
GM will find a way to charge you for using this software. Mary needs her bonus.
Unnecessary and complicated. Innovation for no benefit to the customer. The effort would have been better spent adding rear camera capability to the PDR.
I discovered this problem when I attended the V-Performance Academy at Spring Mountain in September. It’s a pain in the ___. As luck would have it, I also attended Level 1 at Spring Mountain in early October. I told the instructors about my experience with the Blackwing, and they said, don’t worry – the same problem is coming to the 2026 Corvettes. It takes a very simple, convenient feature and transforms it into a kludgy mess. The throttle and brake travel is extremely important, and it is almost unrecognizable with AliveDrive.
Engineers left unchecked always add unnecessary complexity to a situation.
