2014 Porsche Cayman gets a performance-testing iPhone app

To promote the new 2014 Cayman, Porsche has cooked up an iPhone app called “Cayman Code of the Curve.” You're probably already rolling your eyes at the prospect of another automaker app that is little more than a downloadable advertisement, but this seems to be something different -- the app is designed to record your driving performance in real-time and then share results with friends. Porsche enthusiast site flatsixes.com has an exclusive first look at the app, which is still in development but is reported to be coming “soon.” Based on preliminary screenshots provided by Porsche, the app instructs users to set up a variety of courses -- cone slalom, autocross and reaction-time challenge courses are shown -- then uses the iPhone's internal accelerometer and GPS receiver to track and record your performance. You'll also be able to use the app's “record your curve” function to share favorite drives with friends on Facebook.

Let's call them Easter eggs, and they're intricate yet intriguing.

BMW teases 2 Series Coupé with new video [w/Video]

BMW's 2 Series Coupé has been previewed in a video ahead of its reveal later this month. The teaser video – produced in the dramatic style favored by most carmakers – outlines the 2 Series' silhouette and from what we can see it's much sleeker and rounder than its predecessor while generally retaining the same proportions. Although the car – which is the second generation of the 1 Series Coupé – is debuting on 25 October, we won't see it on show stands until next January's North American International Auto Show.
