Vastly different engines power these cars, but they’re still very close
Right at the pinnacle of both BMW and Mercedes’ performance and luxury ranges we find the M760i and the AMG S63 respectively.
One is powered by a big six-liter twin-turbo V12 while the other makes do with a much smaller four-liter twin-turbo V8 engine. Even so, they make nearly identical power, but the Mercedes just nudges torque even with its displacement handicap – it makes 900 Nm versus the BMW’s 800 Nm.
Carwow put the two alongside on a runway to find out exactly which one is quicker and by how much. Standing and rolling start straight line races prove that even with the torque advantage of the S-Class (and the fact that in this comparo, it was nearly 200 kg lighter than its rival) it’s surprisingly close.
