BMW is convinced that extra technology can always help drivers improve their track performance. The idea is you buy an M performance model, you download the new iPhone app and pair it up with your vehicle, take it to a circuit have a detailed analysis of each lap you do.
It’s called M Laptimer App, and it works on newer models equipped with the Professional variant of the infotainment system. It should work on most of the more recent models, and some older ones may be only partially supported (not all functions working properly) or not at all.
The information it can record and replay is genuinely useful and is much more than a mere lap timer. It provides a real-time review of any lap, and also captures throttle, braking and steering input, as well as g-forge, rpm and fuel efficiency.
So, if you find your BMW to be compatible and you sometimes take it out on a racetrack, then perhaps you could give it a try and see how it fares in situations other than the ones shown in the videos posted below.
