It seems like just yesterday we were discussing the debut of the 2014 Corvette Stingray , and now GM is releasing information on the 2015 model year. No, we do not have any hard details on the 2015 Stingray, but GM did reveal the Performance Data Recorder (PDR) , which will be available starting with the 2015 Stingray.
General Motors teamed up with the folks at Cosworth top develop the PDR system, which includes three main components: a 720p camera mounted near the top of the windshield, a self-contained telemetry recorder and an SD memory card slot in the glove box to store the data and video on your own memory card.
The 720p camera eliminates the need to pick up a digital camera capable of withstanding the wear and tear of the track, as it takes high-quality, first-person footage of your track session. There is also a microphone in the cabin, so you can elaborate on what’s going on. You can watch the video either on the eight-inch display in the car when it is parked, or you can upload it to your computer, using the SD card.
The telemetry recorder makes use of a GPS receiver to track the car’s positioning. This is not your standard, choppy, in-dash GPS; rather, this bad-boy operates at 5 hertz — five times faster than a standard GPS — which precisely tracks the Stingray’s positioning and draws a precise driving line that allows you to see how well you tackle turns. Also weaved into this recorder is the Corvette ’s Controller Area Network, allowing it full access to the engine speed, gear selection and steering angle, giving you an in-depth look at how these aspects affect your performance on the track.
There are three overlay modes for the video, with each one displaying only the data you need. The Track Mode displays all of the possible data on the screen, including speed, rpm, G-force, a location-based map and tons of other pertinent info. The Sport Mode reduces the clutter on the screen, but still shows important data, like speed and G-force. Touring Mode only records video and audio, rendering a dash cam useless. The final mode it the Performance Mode, which includes all of the key performance details, including 0-to-60 mph time, quarter-mile time and speed, and 0-to-100-to-0 time.
Using the included Cosworth Toolbox, which shows your lap times on a Bing satellite map, and allows you to compare each lap corner-by-corner.
GM didn’t reveal the price of the PDR, but it made it pretty clear that this will not be a standard feature. This will simply add to the popularity of the Stingray rolling into the next model year. Hat’s off to GM for really putting all it has into the Stingray!

The 2014 Stingray made its debut at the 2013 Detroit Auto Show and it was nothing short of a hit. Sure, the revival of the "Stingray" name took a while to get used to, but its 455-horsepower, 6.2-liter V-8 certainly relieved any of our issues with the recycling of the iconic nameplate. Add to that the optional exhaust system that adds five horsepower and five pound-feet of torque to the mix, and we welcome the Stingray with open arms.
Also available is a Z51 package, which adds in staggered 19- and 20-inch wheels, a dry-sump oil system, electronic limited-slip diff, larger front rotors, a fully upgraded suspension, and much, much more.
The 2014 Corvette starts at $51,000.

Fast Feedback: Corvette Performance Data Recorder
Industry-First System Features Motorsport-Inspired Telemetry Recording Capability
LAS VEGAS – Chevrolet announced at the Consumer Electronics Show today an industry-first Performance Data Recorder for the 2015 Corvette Stingray. The fully integrated system enables users to record high-definition video, with telemetry overlays, of their driving experiences on and off the track.
"The Performance Data Recorder combines the ability to record and share drive videos with the power of a professional-level motorsports telemetry system," said Tadge Juechter, Corvette chief engineer. "Drivers can easily record and share their experiences driving down the Tail of the Dragon or lapping Road Atlanta. In addition, with the included telemetry software, users can analyze their laps in incredible detail and find opportunities to improve their driving and lap times."
The Performance Data Recorder, orPDR, system was developed with Cosworth, the British motorsports-engineering company that supplies the Corvette Racing team’s data acquisition and telemetry electronics system. It will be available with the start of regular 2015 Corvette production, later in the third quarter of 2014. Pricing will be announced closer to launch.
The PDR system includes three major components, all seamlessly integrated into the Corvette Stingray’s interior. First is a 720p, high-definition camera, mounted within the windshield header trim, which records the driver’s point-of-view through the windshield. Audio is recorded via a dedicated microphone in the cabin.
Second is a self-contained telemetry recorder. The system uses a dedicated GPS receiver that operates at 5 hertz, or cycles per second. That is five times faster than the in-dash navigation system and allows more precise positioning and corner traces. The recorder is also hard-wired into the Stingray’s Controller Area Network, or CAN, to access vehicle information, ranging from engine speed and transmission-gear selection to braking force and steering-wheel angle.
Finally, the system features a dedicated SD-card slot in the glove box for recording and transferring video and vehicle data. Recording time depends on the capacity of the memory card, but an 8-gigabyte card can record approximately 200 minutes, while a 32-GB card stores up to about 800 minutes – more than 13 hours of driving time.
The PDR system can record video with three data overlay options, each rendered in real time:
- Track Mode – shows the maximum level of data on the screen, including speed, rpm, g-force, a location-based map, lap time and more.
- Sport Mode – shows fewer details on the overlay but includes key data including speed and g-force
- Touring Mode – simply records and displays video and audio of the drive with no data overlay
- Performance Mode – records performance metrics, such as 0 to 60 mph acceleration, 1/4-mile speed and elapsed time, and 0-100-0 mph runs.
The video can be viewed on the Corvette Stingray’s eight-inch color touchscreen when the car is parked, or downloaded to a computer for further editing, and sharing video via social media sites.
For users who want a more in-depth understanding of their performance, the PDR vehicle data can be opened in the included "Cosworth Toolbox" software, which combines Cosworth’s professional-level motorsport data analysis with an easy-to-use graphic interface.
The Cosworth Toolbox application overlays recorded laps on a Bing-enabled satellite map of the track, and compares selected laps in detail for any requested point on the drive. Comparisons include corner traces, vehicle speed, and cornering force to help drivers improve their driving consistency and ultimately their lap times.
"The ability to review laps between track sessions can identify immediate adjustments for quicker laps in the next session," said Juechter. "It’s like having a 32-GB crew chief trackside providing you with real-time feedback to improve your driving skills."
