Just how quick are the 2016 Cadillac ATS-V coupe and sedan?

The manufacturer estimates 0-to-60 times of under four seconds, regardless of body style or transmission, and a top speed of 189 mph, flat out. In the hands of the world's best drivers, it is a machine to be venerated.

Thanks to the optional, onboard Performance Data Recorder, however, any driver can look like a star. Like a GoPro, the PDR is an accessory to record anything from the daily commute to shareable hot laps—but the comparisons end there. PDR overlays key driving data, from throttle pressure to GPS mapping on some racing circuits, to show exactly why the car is behaving as it does.

Watch as we take the manual-transmission ATS-V for a lap around Texas' most challenging speedway.
