At the 2014 Consumer Electronics Show, Chevrolet announced the Performance Data Recorder (PDR) for the 2015 Corvette Stingray. This fully integrated system enables users to record high-definition videos, as well as telemetry overlays, of their driving experiences. According to GM, the system was developed with Cosworth, the well-known British motorsports-engineering company, same company that spies the Corvette Racing team’s data acquisition and telemetry electronics system. The new Performance Data Recorder system includes three major components: first is a 720p, high-definition camera which is mounted within the windshield header trim and records the driver’s point-of-view.
A microphone in the cabin records everything it hears. Moreover, we find a self-contained telemetry recorder, which uses a dedicated GPS receiver operating at 5 hertz or cycles per seconds, allowing precise positioning and corner traces. The recorder is hard-wired into the Stingray’s Controller Area Network, or CAN, to access vehicle information. Finally, the system comes with a dedicated SD-card slot in the glove box that records and transfers video and vehicle data. An 8 gb memory card can record up to 200 minutes, while a 32 gb card stores up to 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.
