The V-8 diesel version gets an ECU upgrade to give it a total power output of 365 hp and 649 lb-ft of torque. It looks a lot more subtle too. I'm not sure if I'm a fan of the 23's myself, but check it out for yourself. The American Q7 TDI with the V-6 makes 225 hp and 406 lb-ft of torque.http://carscoop.blogspot.com/2009/05/avus-performance-takes-on-audi-q7.html
