The point is in this "new world" where it appears that energy efficiency and conservation agendas will drive most engineering designs until, or if, the next miracle energy breakthrough occurs, everything must be on the table.
Audi has come back to a turbo 5 for the just revealed TTrs (last turbo 5 was in the mid-90s). 340 hp & 330 lb. ft. out of only 2.5 liters. That formula applied to a straight or V-6 would yield over 400 hp and around 400 lb ft; combined with lighter wieght it could be a great performer.
