[VIDEO] Chevrolet Introduces the 2015 Corvette's Performance Data Recorder at CES

We are just over a week away from the introduction of the 2015 Corvette Z06 but thanks to the Consumer Electronics Show kicking off a week before NAIAS, we’re getting a preview of a very cool new tech feature coming to Corvette in 2015.

It’s called the Performance Data Recorder – an advanced video capture system with motorsport-inspired telemetry that drivers can download, view and share.

Chevrolet is introducing the new system at the Consumer Electronics Show on Sunday in Las Vegas.

The Corvette Performance Data Recorder is an integrated audio/video recording system which allows Corvette drivers to record high definition video with telemetry overlays while driving both on and off the track. The telemetry can include data ranging from speed and rpms as well as a G-force meter and showing the location on a track via GPS.

“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.”

Three major components make up the Performance Data Recorder system – the camera, telemetry system and the SD card.

Recording a driver’s view of the action is a 720p high definition camera which is mounted within the windshield header trim. Audio is also recorded via a dedicated microphone in the car’s interior.

The telemetry system, developed with Cosworth who also supplies similar equipment to Corvette Racing, uses a dedicated GPS receiver and operates at 5Hz which Chevrolet claims is five times faster than the in-dash NAV system for more precise positioning. The recorder is hard wired into the Stingray’s Controller Area Network to gain access to vehicle’s information including speed and rpms, transmission gear selection, braking force and steering wheel angle.

The final piece of the system is the dedicated SD card slot in the glove box for recording and transferring the drivers exploits and the vehicle’s data. Recording time is estimated to be up to 800 minutes of video on a 32 GB card. That’s more than 13 hours of drive 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 – no data overlay; it simply records and displays video and audio of the drive

  • Performance Mode – records performance metrics, such as 0 to 60 mph acceleraiton, 1/4-mile speed and elapsed time, and 0-100-0 mph runs.

For those that track their Corvettes, the PDR can be used to gain a greater understanding of their performance driving. Cosworth is including a “software toolbox” which will combine professional-level motorsport data analysis with an easy to use interface.

The Cosworth application will give drivers the ability to compare selected laps in detail, from any point on the drive. Comparisons include corner traces, vehicle speed and cornering force.

In addition to downloading the video for later viewing, the video can be viewed on the Corvette Stingray’s eight-inch color touchscreen when the car is parked.

“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, proving you with real-time feedback to improve your driving skills.”

Corvette Racing driver Tommy Milner drove a Corvette Stingray equipped with the Performance Data Recorder at Sebring International Raceway:

Chevrolet also posted this How-To video for the PDR:

From our conversations with Corvette Team members at a recent briefing about the PDR, we were told that the system will ship on 2015 Corvettes and is not something that can be retrofitted for the 2014 Corvette Stingrays.

With the ease that the Performance Data Recorder will allow weekend warriors the ability to capture their drives, we are sure to see a flood of PDR videos on YouTube and other Corvette video sharing websites once the system ships with the 2015 Corvette.
