Who needs snow? Audi says just use what you've got. In its newest Audi S4 ad for the European marke, the German brands shows a downhill skier doing his thing through the streets of San Francisco, with nary a snowflake in sight. Appropriately titled "San Francisco Abfahrtski!", the video features some cool effects and presumably shows you the visceral thrills that you'll experience while piloting your new supercharged S4. Follow the jump to see the spot for yourself, and pay close attention for the parking meter slalom and the cable car dodge.
