Our colleague John Voelcker of GreenCarReports is on the scene for the unveiling of the new BMW i8 plug-in hybrid sports coupe and i3 electric city car in Frankfurt today, and he's sent us these live images from the event. Jump into the gallery for a more first-hand look at these slick new concepts, expected to hint more closely at the final production models due in 2013 and 2014.

Quick reminder: the i8 gets its power from a 1.5-liter three-cylinder engine that works in conjunction with an electric motor system to deliver high efficiency while also promising sporty capabilities. The i3, on the other hand, is built for slicing and dicing through city streets, running on pure electricity. For a more complete overview of the sleek i8, read our preview here.
