The average BMW driver may not often take their Bimmer out to the track, but those who do can now get some free iOS assisted coaching. The company's BMW M Laptimer app tracks vehicle throttle, steering, braking and engine data and maps it to a pre-defined or user created track, analyzing the driver's performance along the way. Would-be race car drivers can even swap track data with their friends, and play back a virtual head-to-head ghost comparison race to critique each other's laptimes.
Although the tool is clearly designed to be used in a controlled track environment, drivers can also generate custom maps -- giving them an edge in the race to get to their local grocer. Not much has changed since BMW teased the app earlier this summer, but drivers with access to any BMW Apps connected vehicle (not just BMW M models) can pick it up for free today. Just don't have too much fun racing the custom track you'll undoubtedly build for your morning commute.
