Last year at the Frankfurt show, BMW tuning house AC Schnitzer unveiled a radical take on the 6-Series that seemed spectacularly over-flamboyant to have been created by a bunch of German guys. It was called the Tension, and it divided the Frankfurt into two camps, the delighted and the disgusted. But it was just a concept. Now, just about exactly one year later, the production kit is out. They're only converting 50 6-Series models into Tension Street tuners, so act fast. Or look away. Click through for a spec sheet and more pics.
