Analyse this: the Porsche Track Precision App
The Porsche Track Precision App enables drivers to record videos, lap times and car data in one place, for detailed analysis and sharing. Keen to try it out, we joined Porsche’s Sport Auto Perfection Training 2020 at the Nürburgring Nordschleife so we could discover if, like the Porsche Offroad Precision App, it would see us approach the driving task at hand in an altogether different way.
Porsche Track Precision App: tracking
The Porsche Track Precision App (PTPA) is a bit like one of the myriad of fitness apps, but for cars. It is available for iOS and Android devices and, if a Porsche has the Sport Chrono package, the app will pair with the vehicle to enable the driver to track their lap times on more than 300 racing circuits worldwide. It’s a good idea to put your phone in a windscreen-mounted cradle and you can record video at the same time as collecting data – and if you’re unfamiliar with track driving and need a few pointers, it will offer tips, too. While most apps or hardware solutions make use of the smartphone’s quite simple sensor data, or information obtained via the car’s OBD diagnostic port, the PTPA is unusual in that it receives its data directly from the different control units in the car. The amount of information available for later analysis is vast, and it can be viewed either as a graph or alongside the video recording.

Sport Auto Perfection Training day one: the absolute beginner
There is a good reason that the Nürburgring Nordschleife is known as the “Green Hell”: not only is it the longest circuit in the world, but it is also considered one of the most dangerous. My hopes rested on my general driving experience and the instructor who would accompany me around the track.
A total of 26 groups assembled for a briefing from our instructor, Timo Kluck.
Sport Auto Perfection Training day two: putting theory into practice
After a night of typically thunderous Eifel weather, the following morning greeted us with sunshine although when we assembled on track at 08:00, some wet patches remained.
Porsche Track Precision App: analysis mode
When looking at the data in graph-form, we paid particular attention to a diagram showing accelerator position, braking pressure and steering angle. It was clear to see the places in which I hadn’t braked cleanly or where I had perhaps taken my foot off the accelerator too soon.
The Nordschleife in a Porsche 911 Carrera 4S
At this point I should perhaps mention the car I was driving on the Nordschleife: a current generation 911 Carrera 4S. Summary When I reviewed the Porsche Offroad App, I said at the time that I wouldn’t have thought to take a Porsche offroad until I heard about the app. While the thought of driving a 911 or another Porsche on a race track is perhaps more obvious, it is also slightly more daunting and I experienced for myself how a “normal” 911 has motorsport DNA.
The PTPA provides plenty of information about how to drive on a race track and about the things you have to pay attention to with a car.
