QUOTE </td></tr><tr><td id='QUOTE'><!--QuoteEBegin-->The M3 marked the introduction of the S50 B30 engine. This engine was a heavily modified version of the 2.5L M50. It had larger pistons and other enhancements to increase the output. The European version leveraged independent throttle bodies and was unrestricted by catalytic converters which increased output to 286hp. The Euro version also had a different cylinder head than the US version. This makes it virtually impossible to convert a US engine to a Euro engine. However, some suppliers offer third party parts that will work on a US engine. The US version (M50 B30) reverted to the same intake system used with the stock 2.5L M50, and the horsepower was reduced to 240hp. However, BMW did tune the engine and gearing to improve low-end torque for the US driver. As a result, if you were to put a US and Euro side by side, they would perform just about the same up to about 60mph. It is on the high end where the Euro version takes advantage of the intake system. This makes sense given that they have the Autobahn and we are limited to 55mph (legally).<!--QuoteEnd--></td></tr></table><div class='postcolor'><!--QuoteEEnd-->
OK, donc en gros c'est pas trop grave d'avoir plus de couple à bas régime et moins de watts en haut mais c'est moins drole quand-même <!--emo&

Ca explique aussi pourquoi aux US les M3 E36 sont carrément moins cheres aux vues du reste de la gamme E36 et E46 que les mêmes M3 en Europe !
Ca reste une voiture intéressante. Les améliorations chassis restent là visiblement.
