We've run across some rather interesting news... or perhaps we should say interesting sounds. The folks from Bimmerpost have scrounged up a short video showing a preproduction BMW i8 running through a few gears in Sport mode at a quick pace, and if you were concerned that the somewhat eco-friendly nature of the upcoming German sports car would neuter its ability to stir the aural senses, fret not.

Here's an interesting tidbit we missed while scouring through BMW's massive press release on the 2012 M5. According to the text, BMW has employed a system it's calling "Active Sound Design" on the new M5, which takes in engine speed and load data from the ECU and plumbs it through the stereo to play a real-time recording of the M5's engine.
