The sheer number of tuning packages for the new Audi RS6 offering more than 700hp (522kW) that has turned up almost overnight just goes to show how much potential the standard car’s 5.0L V10 has. Already we’ve seen such monstrous tuning kits from MTM and ABT Sportsline, and now we have the most powerful kit yet. The latest is from fellow German tuner B&B and the top spec package is rated at 715hp (533kW).
