This site reports that Audi has been testing in nurburgring the new RS6 that incorporates the Gallardo's V10 engine and will be caller Audi RSR6 with 507HP. It will compete with the 550HP V10 M5. Wonder what Mercedes will come up with... its getting crazy, people only care about horsepower nowadays, not grip/traction, weight, steering, brakes, suspensions...why do the cars that get most HP in today's market are cars not made to handle it or designed for performance?
