First dynojet numbers for the Mercedes 5.5 liter twin turbo M157 - Insideline dyno tests the 2011 S63 AMG with Performance Package
We know you have been waiting for dyno numbers for the M157 with baited breath just like we have. Now, the sleepless nights can finally come to an end. Insideline dyno tested the S63 AMG featuring the new twin turbo V8 powerplant with the optional Performance Package and all we have to say is: TORQUE, A LOT OF TORQUE. Wow, over 600 pound-feet at the wheels. They also overlaid the graph with the M159 naturally aspirated v8 out of the Mercedes SLS AMG and once you see the curves compared we don't think you or anyone else is going to miss the M156/M159 motor very much.
