2011 Audi A7 Sportback 2012 Audi RS7 may reach for the 600 horsepower mark to outdo the next BMW F10 M5 email print Share 0 By Alex Ricciuti December 16, 2010 1:00 pm Filed Under: Audi, German, Rumours Could Audi really go all the way with the RS7 and leave behind the competition in the horsepower wars? According to American car magazine Road & Track, rumor has it that Audi may be working on a 600 bhp (608 PS / 447 kW) RS7 performance variant of the A7. Under the bonnet would come a twin-turbo 4.0 liter V8 engineered to deliver that level of output. That power quotient would surpass the expected output of the next BMW M5 (F10) which will come with a 4.4 liter-twin-turbo V8 producing 570 hp (425 kW / 578 PS). To handle all that power, the RS7 will feature Audi's all-wheel drive Quattro system with a torque vectoring differential. The RS7 will also come with an adaptive suspension, larger front air intakes and 19 and 20-inch wheels. The 2012 Audi RS7 is expected to debut late next year.
