APEX Pro changes the game on predictive performance data

T he path to quicker lap it typically involves a display with predictive lap timing and how quickly a driver is going in relation to his fastest lap. Post session, it most often involves taking a faster driver’s lap data and laying it over the slower lap to show where the potential gains are. A new company called APEX approaches the problem from a different perspective. Rather than basing in-car feedback on a driver, the new APEX Pro bases it on machine-learning the capabilities of the car. In addition, rather than displaying the feedback digitally, it shows it in a clever array of red and green lights. Post session, the times ultimately involves data. From inside the car,

data can be downloaded via Bluetooth to an iOS device, such as an iPhone or iPad. There is an app for Androids, too, but the data it displays is more basic. The company is developing its Android and PC-based software. “APEX Pro essentially uses inertial sensors only and GPS all internal to the device to build a model of your vehicle’s capabilities while you drive,” said APEX marketing director Andrew Rains. “It doesn’t use a predisposed baseline for an individual track or an individual car. It simply just learns based on the accelerations that it’s seeing, what your car’s capabilities are, and it extrapolates that to a nine-axis friction circle. It starts to learn where the limits of grip are.”
