Scott, I'm quite sure you know about the new 4.7liter twin turbo v8 engine that mercedes has just developed. It cranks out 435hp and 516lbft (700nm) of torque and mercedes is going to be rolling it out on the facelifted cl coupe and the s class this fall. This engine seems to have "one upped" the current bmw twin turbo 4.4l engine found in the 750li which cranks out 407hp and 442lbft(600nm) of torque. My question to you is this; is bmw planning to upgrade their v8 engine in response to the new engine from mercedes?
