Chevrolet has announced at the Consumer Electronics Show the introduction of 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, or PDR, system was developed with Cosworth and will be available with the start of regular 2015 Corvette production, later in the third quarter of 2014. The PDR system includes three major components, all 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 and audio is recorded via a 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.
Lastly, the system features a dedicated SD-card slot in the glove box for recording and transferring video and vehicle data. An 8-gigabyte card can record approximately 200 minutes, while a 32-GB card stores up to about 800 minutes of driving time. The video can be viewed on the Corvette Stingray’s eight-inch touchscreen when the car is parked, or downloaded to a computer.
“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.”
