By recording metrics such as satellite positioning, pedal depression, steering angle, gear selection, engine revs and vehicle speed, Sports Drive Logger can then replicate this data in the Gran Turismo 6 game on PlayStation 3. You can view this data in the game's telemetry screens, and even watch a virtual representation of the laps you've just driven. As an added competitive element, you can also compare that data to those of your friends. Great for comparing notes, not so great for the guy whose data-logger refutes claims he pulled off an epic drift "that nobody saw". If you feel like a real challenge, you can compare your data with that of professional drivers, too.
The system, developed in conjunction with Sony, only supports Fuji, Suzuka and Tsukuba so far--but other circuits are sure to join them. Hopefully, it'll make it to the U.S. and Europe too, so FR-S, GT 86 and BRZ drivers can compare their real-life laps with those they've achieved in the game. It doesn't come cheap--the quoted 91,800 Yen currently equates to $890--but it certainly adds an extra dimension to the weekend's track days.
