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
The Performance Data Recorder, or PDR, system was developed with Cosworth, the British motorsports-engineering company that supplies the
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:
.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.'
