General Motors Co. Chevrolet brand Sunday is expected to announce what it calls an industry-first performance data recorder, available on 2015 Chevrolet Corvette Stingray models and geared for drivers who take their Corvettes to the racetrack.
The company will make the announcement ahead of the 2014 International Consumer Electronics Show in Las Vegas.
The optional system, first available in late third quarter 2014, was developed with British motorsports engineering company Cosworth Group that supplies Corvette Racing. It will allow drivers to record high-definition video and audio, and overlay vehicle data such as speed and rpms on the video.
“We’ve been wanting to do this for awhile,” said Tadge Juechter, chief engineer of the Chevrolet Corvette.
Corvette Racing driver Tommy Milner, in a video, said Chevrolet’s performance data recorder combines “video quality of a GoPro” and GPS-based telemetry.
GM will mount a high-definition camera in the Corvette’s windshield header trim. A telemetry recorder in the vehicle uses a GPS system that is five times faster than the in-car navigation system. That recorder is hardwired into the car to access vehicle information such as speed, transmission gears and braking force.
“It’ll record on an SD card and all the data from the vehicle will be recorded simultaneously and be synced up,” Juechter said, adding a 32GB SD card can record up to 800 minutes.
Recorded videos can be viewed in the Corvette’s center screen when it is parked, allowing drivers to review driving and make corrections before heading out for another lap, Juechter said. Users also can pull the SD card from the vehicle, download the video to a computer and share via social media.
“We think (it’s) a really cool system that people are really going to enjoy and really goes well with the performance mission of the Corvette,” he said.
Drivers can select modes that overlay data with details such as rpm, g-force and maps to one that just gives a view of the road.
Pricing on the system has not been announced by GM, spokesman Monte Doran said. But it’s expected to cost between $1,000 and $1,500.
Recordings also can be viewed in “Cosworth Toolbox” software, which allows drivers to study their capabilities behind the wheel and compare lap times. The method is similar to what the Corvette Racing team does, as the team studies data and instructs drivers on where to find more speed, Juechter said.
“It’s another example of tech transfer from the racetrack to the street,” he said.
