Chevrolet will offer a performance data recorder on the 2015 Corvette Stingray, underscoring the latest push by automakers to offer advanced technology to differentiate their car and light-truck lineups.

The system -- while ideally suited to a racing enthusiast -- can record high-def video of a driver's experience on the road or track, and it includes telemetry overlays.

Chevy calls it an industry first; the recorder was developed with British race-engineering company Cosworth, which supplies the Corvette Racing team's data acquisition and telemetry system.

"The Performance Data Recorder combines the ability to record and share drive videos with the power of a professional-level motorsports telemetry system," Tadge Juechter, Corvette chief engineer, said in a statement Sunday at the Consumer Electronics Show in Las Vegas. "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 recorder will be available with the start of regular 2015 Corvette production this Fall. Pricing will be announced closer to launch.

The system includes three major components, all integrated into the Stingray's interior.

It uses a high-def camera mounted in the windshield-header trim. It records the driver's point-of-view through the windshield. Like recorders found on commercial aircraft, a microphone in the cabin captures audio, such as the colorful language a driver might spew after failing to properly navigate a hairpin turn.

The system also features a self-contained telemetry recorder using a GPS receiver to access vehicle information ranging from engine speed and gear selection to brake force and steering-wheel angle.

And there's a dedicated SD-card slot in the glovebox for recording and transferring video and data. Recording time depends on the capacity of the card's memory. An 8-GB card can record about 200 minutes, while a 32-GB card stores up to about 800 minutes -- or more than 13 hours of driving time.

There are three data-overlay options on the video: Track mode shows the most data on the screen, including speed, rpm, g-force, a location-based map, lap time and more.

Sport mode has less detail but includes speed and g-force. Touring mode just records and displays video and audio of the drive -- no data. Performance mode records 0-60 times, ¼-mile times, road-course times and the like.

The video can be viewed on the Stingray's touchscreen display when the car is parked, or it can be downloaded to a computer for further editing and sharing via social media if the owner is so inclined.

The data can also be opened in the Cosworth Toolbox software (it comes with the system).

It combines Cosworth's pro-level data analysis with an easy-to-use graphic interface. The Toolbox overlays recorded laps on a track-satellite map and compares selected laps in detail for any requested point on the drive.

Owners can compare corner traces, car speed, and cornering force to help you improve your consistency and 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."
