mercedes benz make wonderful cars, no mistaking that. my wife drives a c180k and it is terrific.

spitfire, have you considered that although mb & bmw are fierce rivals, most of mbs cars are less powerful than their bmw equivalents.

another point to note is that although both rivals analyse each others cars to the tiniest screw, ultimately bmw build cars one way and mb build them their way.

many petrol mbs are supercharged while bmw do not use supercharges in their cars and for the most part have better power and torque figures than mb. also it is seemingly evident that bmw understate certain performance figures as well. i do not know about mb.

mb build v6s while bmw are the straight 6 champion of the world.

when you go head to head in a medium term comparison between the bmw and mb high performance sports cars can we really see what the answers to your questions are like.

quoting figures is one thing and mb do quote very large figures but in the past, bmw m series cars have outperformed their amg rivals in many a car magazine comparison.

personally speaking i believe this trend will continue with the new m5 and m6.

do not misunderstand me, mb build top high performance cars as well. it is up to the individual to decide which one they like better based on whatever method they choose but deciding on some figures alone is not the answer.

all the best.
