2015 Chevrolet Corvette Stingray to get Performance Data Recorder

Motor Trend logo Motor Trend 1/5/2014 Jason Udy

Chevrolet Announced during the 2014 Consumer Electronics Show (CES) that the 2015 Corvette Stingray will be available with an optional Performance Data Recorder (PDR). The automaker claims the PDR is the first of its kind in a production model. With the PDR, Corvette drivers can record high-definition video with telemetry overlays of their on- and off-track driving.

“The ability to review laps between track sessions can identify immediate adjustments for quicker laps in the next session,” said Corvette chief engineer Tadge Juechter in a release. “It’s like having a 32-GB crew chief trackside, providing you with real-time feedback to improve your driving skills.”

Developed with help from Cosworth -- the same company that supplies the Corvette Racing team’s data acquisition and telemetry electronics systems -- the PDR is a fully integrated system featuring a 720p high-definition camera, a self-contained telemetry recorder, and a dedicated SD-card slot. The camera is mounted in the windshield header trim and records the driver’s point-of-view through the windshield, while a dedicated microphone records in-cabin audio.

Hard-wired into the Corvette’s Controller Area Network (CAN), the recorder can access vehicle information including engine speed, transmission gear selection, braking force, and steering wheel angle. Located in the glove box, the SD-card slot allows recording and transferring video and vehicle data from the car to a computer. Approximately 200 minutes can be stored on an 8GB card and about 800 minutes on a 32GB card.

The PDR system offers four performance modes: Track, Sport, Touring, and Performance. In Track Mode, all of the available data is displayed on the screen including speed, rpm, g-force, a location-based map, lap times and more. While the Sport Mode shows less data than Track Mode, it displays speed, g-force, and other stats. In Touring Mode, the PDR displays video and audio without any data overlay. Finally, Performance Mode records acceleration stats including 0-60 mph time, quarter-mile time and speed as well as 0-100-0 mph runs.

When parked, videos can be played on the Corvette’s center console touchscreen or downloaded to a computer where they can be edited or uploaded to the internet. Videos can also be opened in the included “Cosworth Toolbox” software for further data analysis including point-to-point lap comparisons, corner traces, vehicle speed, and cornering force.

The PDR will be available as an option on the 2015 Chevrolet Corvette Stingray, which begins production in the third quarter of 2014. Pricing for the system will be announced closer to launch.
